Development and optimization of metoclopramide containing polymeric patches: impact of permeation enhancers

Abstract The study is aimed to develop a monolithic controlled matrix transdermal patches containing Metoclopramide as a model drug by solvent casting method. Eudragit L100, Polyvinylpyrrolidone K-30, and Methylcellulose were used in different ratios and Polyethylene glycol 400 added as a plasticizer. Resulting patches were evaluated for their physicochemical characters like organoleptic characters, weight variation, folding endurance, thickness, swelling index, flatness, drug content, swelling index, percentage erosion, moisture content, water vapor transmission rate and moisture uptake. Formed patches were also evaluated through Fourier transform spectroscopy (FT-IR), X-ray diffraction (XRD), Differential Scanning calorimetry (DSC) and Scanning Electron Microscopy (SEM). Results of SEM unveiled smooth surface of drug-loaded patches. In-vitro dissolution studies were conducted by using dissolution medium phosphate buffer saline pH 7.4. Effect of natural permeation enhancers was elucidated on two optimized formulations (Z4 and Z9). Different concentrations (5%-10 %) of permeation enhancers i.e. Olive oil, Castor oil and Eucalyptus oil were evaluated on Franz diffusion cell using excised abdominal rat skin. Z4-O2 (Olive oil 10%) had enhanced sustain effect and flux value (310.72) close to the desired flux value. Z4-O2 followed Higuchi release model (R2= 0.9833) with non-fickian diffusion release mechanism (n=0.612)

An attempt to enhance solubility of metoclopramide base by Solid dispersion strategy and its application on development of Transdermal device

Chemotherapy induced nausea and vomiting (CINV) is an issue, which usually occurs in cancer patient. Despite high bioavailability of oral and intravenous administration, these have some drawbacks. The oral route causes hepatic first pass metabolism and intravenous route is invasive in nature. Hence, antiemetic drug by means of transdermal route is necessary to administer in such cases. The aim of the present investigation is to develop suitable Transdermal Therapeutic System (TTS) with an objective to enhance solubility and skin permeability properties of metoclopramide base. Preformulation study begins with an approach to enhance solubility of 40 metoclopramide base by solid dispersion technique. transdermal films were prepared with 41 the solid dispersion as well as with pure drug. Phase solubility study at various temperatures reveals binding constants (Ka, 95-350 M-1 for PVP K30; 56-81 M-1 for HPßCD). Spontaneity of solubilization was justified by AL type linear profiles. The films showed satisfactory diffusion (%), permeation rate and flux after 8 h study. The transdermal patches as prepared were analyzed under FTIR, DSC and SEM. Both solubility and permeability rate in this investigation have been enhanced. So, it can be affirmed that this route would effectively enhance bioavailability

Effect of acupuncture on the prevention of nausea and vomiting after laparoscopic cholecystectomy: a randomized clinical trial / Efeitos da acupuntura para a prevenção de náuseas e vômitos após colecistectomia laparoscópica: estudo clínico randomizado

Abstract Background and objectives: Postoperative nausea and vomiting (PONV) is a common and undesirable complication observed after laparoscopic cholecystectomy (LC). We investigated the effects of auriculoacupuncture (AA) on the prevention of postoperative nausea and vomiting in the immediate postoperative period of uncomplicated laparoscopic cholecystectomy. Methods: Sixty-eight patients were randomly divided into two groups, auriculoacupuncture (n = 35) and control (n = 33), and then they were evaluated prospectively. The needle was placed before anaesthesia induction and remained for 20 minutes. Nausea intensity was evaluated using an analogic visual scale and PONV events were registered immediately after anaesthesia care unit admission and in the second, fourth and sixth hours after the surgery. Results: The auriculoacupuncture group had a significantly smaller incidence of nausea and vomiting than the control group throughout the whole postoperative period (16/35 vs. 27/33, p= 0.03 and 4/35 vs. 15/33, p= 0.005, respectively); the AA group had fewer nausea events 2 h (p= 0.03) and 6 h (p= 0.001) after surgery and fewer vomiting events 2 h (p= 0.01) and 6 h (p= 0.02) after surgery. Conclusions: Auriculoacupuncture can partially prevent postoperative nausea and vomiting when compared to metoclopramide alone after uncomplicated laparoscopic cholecystectomy. Auriculoacupuncture can be recommended as an adjuvant therapy for postoperative nausea and vomiting prevention in selected patients.

Resumo Justificativa e objetivos: Náuseas e vômitos são complicações comuns e indesejáveis no pós-operatório de colecistectomia laparoscópica (CL). Nós investigamos os efeitos da auriculoacupuntura (AA) para a prevenção de náuseas e vômitos no período pós-operatório (NVPO) imediato da CL não complicada. Métodos: 68 pacientes foram aleatoriamente divididos em dois grupos, auriculoacupuntura (n = 35) e controle (n = 33), e foram avaliados prospectivamente. A agulha foi aplicada antes da indução anestésica e permaneceu no lugar por 20 minutos. A intensidade da náusea foi avaliada mediante escala visual analógica e episódios de NVPO foram registrados imediatamente após a admissão na unidade de recuperação anestésica e duas, quatro e seis horas após a cirurgia. Resultados: O grupo AA apresentou significativamente menos episódios de NVPO do que o grupo controle durante todo o período pós-operatório (16/35 vs. 27/33, p = 0,03 e 4/35 vs. 15/33, p = 0,005, respectivamente). O grupo auriculoacupuntura apresentou episódios de náuseas menos intensos às 2 horas (p = 0,03) e 6 horas (p = 0,001) após a cirurgia e menos episódios de vômitos 2 horas (p = 0,01) e 6 horas (p = 0,02) após a cirurgia. Conclusão: A auriculoacupuntura aliviou náuseas e vômitos no pós-operatório em número significante de pacientes, mas não foi capaz de prevenir náuseas e vômitos no pós-operatório em todos os pacientes. Ela pode ser recomendada como terapia adjuvante para prevenção de náuseas e vômitos no pós-operatório no pós-operatório de colecistectomia laparoscópica em pacientes selecionados.

Drug interactions in maternal intensive care: prevalence, risk factors, and potential risk medications / Interações medicamentosas em terapia intensiva materna: prevalência, fatores e medicamentos de risco

ABSTRACT Objective: To characterize severe potential drug interactions in maternal intensive care, and to determine their frequency, risk factors and potential risk medications. Methods: An observational and longitudinal study conducted between December 2014 and December 2015 in a maternal intensive care unit. Clinical data were collected and severe potential drug interactions were identified on pregnant inpatients. The drug interactions were classified by type, prevalence and exposure rate. A multivariate logistic regression model was used to identify the severe potential drug interactions and the related drugs (p<0.05). Results: A total of 95.1% of patients were exposed to, at least, one potential drug interaction; in that, 91.7% 33.9% were related to, respectively, moderate and severe potential drug interactions. The patients were exposed, on average, on 69.2% of days they were in the intensive care unit. The main drugs involved in more severe drug interactions were magnesium sulfate, metoclopramide, propranolol and diazepam. Conclusion: The severe potential drug interactions were observed in almost all patients of the study, and, approximately one third of those interactions were related to greater severity and resulted in exposure during long hospital stay. The higher number of prescribed drugs and its previous use of medications at home increase the occurrence of severe potential drug interactions.

RESUMO Objetivo: Caracterizar as interações medicamentosas potenciais graves em terapia intensiva materna, e determinar sua frequência, os fatores e os medicamentos de risco associados à ocorrência dessas interações. Métodos: Estudo observacional e longitudinal executado entre dezembro de 2014 a dezembro de 2015, conduzido em uma unidade de terapia intensiva materna. Foram coletados dados clínicos e identificadas interações medicamentosas potenciais graves de gestantes admitidas. As interações medicamentosas foram caracterizadas quanto ao tipo, à prevalência e à taxa de exposição. Um modelo multivariado de regressão logística foi utilizado para identificação de fatores associados à ocorrência de interações medicamentosas potenciais graves e os medicamentos implicados (p<0,05). Resultados: Um total de 95,1% das pacientes foi exposto a, no mínimo, uma interação medicamentosa potencial, com 91,7% delas envolvidas com interações medicamentosas potenciais moderadas e 33,9% com as interações graves. As pacientes ficaram expostas, em média, em 69,2% dos dias que estiveram sob terapia intensiva. Os principais medicamentos implicados em interações medicamentosas de maior gravidade foram sulfato de magnésio, metoclopramida, propranolol e diazepam. Conclusão: As interações medicamentosas potenciais graves ocorreram na maioria das pacientes avaliadas. Aproximadamente um terço das interações foram graves e levaram à maior exposição por um longo período de internação. Maior número de fármacos prescritos e uso prévio domiciliar de medicamentos elevam a ocorrência de interações medicamentosas potenciais graves.

O uso de metoclopramida em mulheres em trabalho de parto: uma revisão sistemática com metanálise / The use of metoclopramide in women in labor: a systematic review with meta-analysis

Revisão sistemática com metanálise que buscou evidências científicas sobre o efeito do cloridrato de metoclopramida na evolução do trabalho de parto, a partir de ensaio clínico controlado randomizado e recomendações da Cochrane Collaboration. A busca atemporal e sem restrições de idioma, estruturada na estratégia PICOS-T, foi realizada em bases de dados Scopus, PubMed, EMBASE, Cochrane, CINAHL e Scielo, literatura cinzenta e referências cruzadas, com estratégias e descritores específicos. As ferramentas Rayyan e EndNote Basic foram adotadas para gerenciar as referências. O estudo foi conduzido por dois avaliadores independentes e a concordância entre eles foi medida pelo Índice Kappa. Foram identificados 2.884 artigos, mas apenas 04 eram elegíveis e a qualidade metodológica destes (risco de viés e sigilo de alocação) foi avaliada com base no Cochrane Collaboration Risk of Bias Tool. O Grades of Recommendation, Assessment, Development and Evaluation foi utilizado para avaliar qualidade das evidências e força das recomendações. O relato desta pesquisa foi baseado no Preferred Report Items for Systematic Reviews and Meta-Analyzes. Não houve conflitos de interesse e qualquer tipo de financiamento. Os estudos incluídos datam de 1982 a 1992, tem 734 parturientes, "Baixo Risco de Viés" (50%) ou "Risco de Viés Incerto" (50%) e "Sigilo de Alocação Adequado" (75%). Para Ahmed et al. (1982) a metoclopramida não é eficaz para iniciar a dilatação do colo uterino no trabalho de parto espontâneo. Para Vella et al. (1985) a metoclopramida não interfere no tempo de trabalho de parto. Para Rosemblatt et al. (1991) a metoclopramida pode atuar para coordenar as contrações do útero e melhorar a força expulsiva, reduzir o tempo e facilitar a passagem do feto. Para Rossemblatt et al. (1992) doses repetidas de metoclopramida provocam redução gradativa na duração de trabalho de parto, parto e dequitação. A metanálise com 02 estudos (92 parturientes) encontrou Mean Difference= 0.8116 e RR= 0.811 (IC 95%). O tempo médio de dilatação (horas) após uso de metoclopramida versus placebo foi 4.43 versus 2.21 para Ahmed et al., com RR= -2.22. Para Rosemlatt et al., este tempo foi 4.56 versus 8.74, com RR= 4.18. O p-valor= 0.7995 revelou que não tem diferença rejeitar ou não a hipótese nula referente ao desfecho clínico pesquisado (dilatação do colo uterino). O I2= 91,56% revelou alta heterogeneidade entre os estudos e limitada aplicabilidade de seus resultados. O Teste Q de Cochran= 11.84 mostrou que há diferença de efetividade entre os resultados, rejeitando a hipótese nula citada. O "Forest Plot" mostrou que as intensidades dos resultados individuais de cada estudo diferem entre si, o que significa ausência de efeito em relação ao desfecho clínico. Este estudo apresenta nível de evidência moderado e forte recomendação dos resultados. Não há comprovação científica de que a metoclopramida favorece a dilatação do colo uterino no trabalho de parto, portanto seu uso não é recomendado. As limitações deste estudo envolveram escassos estudos elegíveis e importantes diferenças nos resultados e medições dos estudos da amostra. Novas pesquisas experimentais devem ser realizadas. As evidências deste estudo são importantes para subsidiar a prática baseada em evidência na atenção ao parto e nascimento e melhorar os desfechos materno e neonatal

A systematic review with meta-analysis that sought scientific evidence on the effect of metoclopramide hydrochloride on the evolution of labor, from a randomized controlled clinical trial and recommendations from the Cochrane Collaboration. The timeless search and without language restrictions, based on the PICOS-T strategy, was performed in databases Scopus, PubMed, EMBASE, Cochrane, CINAHL and Scielo, gray literature and cross-references, with specific strategies and descriptors. The Rayyan and EndNote Basic tools were adopted to manage the references. The study was conducted by two independent evaluators and the agreement between them was measured by the Kappa. 2.884 articles were identified, but only 04 were eligible and their methodological quality (risk of bias and allocation secrecy) was evaluated based on the Cochrane Collaboration Risk of Bias Tool. The Grades of Recommendation, Assessment, Development and Evaluation was used to evaluate the quality of the evidence and the strength of the recommendations. The report of this research was based on the Preferred Report Items for Systematic Reviews and Meta-Analyzes. There were no conflicts of interest and any kind of financing. The included studies date from 1982 to 1992, have 734 parturients, "Low Risk of Bias" (50%) or "Uncertain Bias Risk" (50%) and "Adequate Allocation Secrecy" (75%). For Ahmed et al. (1982) metoclopramide is not effective in initiating cervical dilatation in spontaneous labor. For Vella et al. (1985) metoclopramide does not interfere with labor time. For Rosemblatt et al. (1991) metoclopramide can act to coordinate the contractions of the uterus and improve the expulsive force, reduce the time and facilitate the passage of the fetus. For Rossemblatt et al. (1992) repeated doses of metoclopramide cause a gradual reduction in the duration of labor, childbirth and placental clearence. The meta-analysis with 02 studies (92 parturients) found mean difference = 0.8116 and RR = 0811 (CI 95%). The mean time of dilation (hours) after use of metoclopramide versus placebo was 4.43 versus 2.21 for Ahmed et al., with RR =-2.22. For Rosemlatt et al., this time was 4.56 versus 8.74, with RR = 4.18. The P-value = 0.7995 revealed that it has no difference to reject or not the null hypothesis referring to the clinical outcome investigated (uterine cervix dilatation). The I2 = 91.56% showed high heterogeneity between studies and limited applicability of its results. The Cochran Q Test = 11.84 showed that there is a difference in effectiveness between the results, rejecting the null hypothesis cited. The "Forest Plot" showed that the intensities of the individual results of each study differ, which means no effect in relation to the clinical outcome. This study presents a moderate level of evidence and a strong recommendation of the results. There is no scientific evidence that metoclopramide favors uterine cervix dilation in labor, therefore its use is not recommended. The limitations of this study involved scarce eligible studies and important differences in the results and measurements of the sample studies. New experimental studies should be carried out. The evidences of this study are important to subsidize the evidence-based practice in childbirth care and birth and to improve maternal and neonatal outcomes

Farmacovigilancia activa de metoclopramida 10 mg oral en pacientes del Programa de Alivio del Dolor y Cuidados Paliativos o diabetes mellitus tipo 2 en cinco hospitales del Servicio de Salud Viña del Mar-Quillota / Extrapyramidal adverse reactions to metoclopramide: a pharmacovigilance survey

Background: In 2013 the Chilean regulatory sanitary agency issued a warning concerning dose adjustment and use restriction to avoid severe adverse effects of metoclopramide such tardive dyskinesia. Aim: To study dyskinesia type adverse effects in a population using metoclopramide. Material and Methods: A cross sectional observational study was conducted among patients pertaining to palliative care and diabetes mellitus programs and consuming 10 mg/day or more of metoclopramide. Patients were interrogated looking for extrapiramidal signs and symptoms using a questionnaire validated by two neurologists. Results: In 40% of diabetic patients with gastroparesia and 35% of palliative care patients, extrapyramidal adverse reactions to metoclopramide were suspected. Palliative Care patients suffered the largest number of adverse events. The period of use and individual doses of the drug were largely above Chilean regulatory agency recommendations in all cases. Conclusions: A significant number of patients using metoclopramide could experience extrapyramidal adverse reactions.

Bromopride, metoclopramide, or ondansetron for the treatment of vomiting in the pediatric emergency department: a randomized controlled trial / Bromoprida, metoclopramida ou ondansetrona no tratamento de vômito no departamento de emergência pediátrica: ensaio controlado randomizado

Abstract Objective: To compare the effectiveness of a single intramuscular dose of bromopride, metoclopramide, or ondansetron for treating vomiting. Methods: Randomized controlled trial including children 1-12 years of age presenting with acute vomiting at the pediatric emergency department. Outcomes: Number of children that stopped vomiting at one, six, and 24 h following treatment; episodes of diarrhea; acceptance of oral liquids; intravenous rehydration; return to hospital and side effects. Results: There were 175 children who completed the study. Within the first hour after treatment, all drugs were equally effective, with ondansetron preventing vomiting in 100%, bromopride in 96.6%, and metoclopramide in 94.8% of children (p = 0.288). Within six hours, ondansetron was successful in preventing vomiting in 98.3% of children, compared to bromopride and metoclopramide, which were successful in 91.5% and 84.4% of patients, respectively (p = 0.023). Within 24 h, ondansetron was superior to both other agents, as it remained efficacious in reducing vomiting in 96.6% of children, as opposed to 67.8% and 67.2% with bromopride and metoclopramide, respectively (p = 0.001). The ondansetron group showed better acceptance of oral liquids (p = 0.05) when compared to the bromopride and metoclopramide. The ondansetron group did not show any side effects in 75.9% of cases, compared to 54.2% and 53.5% in the bromopride and metoclopramide groups, respectively. Somnolence was the most common side effect. Conclusions: A single dose of ondansetron is superior to bromopride and metoclopramide in preventing vomiting six hours and 24 h following treatment. Oral fluid intake after receiving medication was statistically better with Ondansetronwhile also having less side effects compared to the other two agents.

Seguimiento e impacto de la divulgación de cinco alertas sanitarias de medicamentos en f1Colombia / Monitoring and impact of the disclosure of five health alerts for drugs in Colombia

RESUMEN Objetivo Realizar la notificación y verificar el seguimiento de cinco alertas sanitarias de medicamentos a un grupo de prestadores de salud en Colombia. Métodos Estudio cuasi-experimental, prospectivo, antes y después, sin grupo control, mediante una intervención en médicos prescriptores de ketoconazol, metoclopramida, nimesulida, diacereina, ranelato de estroncio. Se tomó como población universo a los afiliados al régimen contributivo del Sistema de Salud Colombiano en 13 entidades promotoras de salud (EPS) de Colombia. Se identificaron los pacientes que recibían mensualmente estos medicamentos previamente a la alerta. Se realizó una intervención educativa y posteriormente se midió la proporción de cambio en la dispensación. Resultados Se realizaron en total unas 26 actividades diferentes a 500 médicos prescriptores. De un total de 4 121 954 de personas se identificaron 13 979 pacientes mensuales en 2013 que recibían alguno de los cinco medicamentos y se observó una reducción en 1 470 sujetos al mes (-10,5%) para 2014. El medicamento con el que se consiguió la mayor reducción fue ketoconazol (-31,1% de casos), seguido de ranelato de estroncio (-30,3%) y metoclopramida (-8,6%). Para nimesulida (+0,7%) y diacereina (+16,4%) no se obtuvieron resultados favorables. Conclusiones Se mantienen prescripciones potencialmente riesgosas en pacientes de Colombia. Con intervenciones basadas en farmacovigilancia posterior al reporte de alertas por agencias reguladoras sanitarias, se puede disminuir la proporción de pacientes que utilizan estos medicamentos.(AU)

ABSTRACT Objective Make the notification and monitoring compliance with five health drug alerts to a group of health care providers in Colombia. Methods Quasi-experimental, prospective, before-after study, without control group, by intervening in physician prescribers of ketoconazole, metoclopramide, nimesulide, diacerein, strontium ranelate. The affiliated population of the contributory system of the Colombian Health System was taken as the universe population sample from 13 health promoting entities (EPS) of Colombia. Patients receiving monthly these drugs prior to the alert were identified. An educational intervention was performed and then the rate of change in the dispensation was measured. Results About 26 different activities were conducted on 500 prescribers. Out of a total of 4 121 954 people, 13 979 patients were identified monthly in 2013, who received some of the five medications. Likewise, a reduction in 1,470 subjects per month (-10.5%) for 2014 was observed. The drug which achieved the greatest reduction was ketoconazole (-31.1% of cases), followed by strontium ranelate (-30.3%) and metoclopramide (-8.6%). For nimesulide (+ 0.7%) and diacerein (+ 16.4%) no favorable results were obtained. Conclusions Patients with potentially risky prescriptions remain in Colombia; educational pharmacovigilance interventions made after the report alerts given by drug regulatory agencies may decrease the proportion of patients using these drugs.(AU)

Lactation Induction in a Commissioned Mother by Surrogacy: Effects on Prolactin Levels, Milk Secretion and Mother Satisfaction / Indução da lactação em mãe por útero de substituição: efeitos na concentração de prolactina, produção láctea e satisfação materna

Abstract Case report of a 39-year-old intended mother of a surrogate pregnancy who underwent induction of lactation by sequential exposure to galactagogue drugs (metoclopramide and domperidone), nipple mechanical stimulation with an electric pump, and suction by the newborn. The study aimed to analyze the effect of each step of the protocol on serum prolactin levels, milk secretion and mother satisfaction, in the set of surrogacy. Serum prolactin levels and milk production had no significant changes. Nevertheless, themother was able to breastfeed for four weeks, and expressed great satisfaction with the experience. As a conclusion, within the context of a surrogate pregnancy, breastfeeding seems to bring emotional benefits not necessarily related to an increase in milk production.

Resumo Relato de caso de mãe por útero de substituição, de 39 anos de idade, submetida a indução da lactação por exposição sequencial a drogas galactogogas (metoclopramida e domperidona), estimulação mamilar mecânica com bomba elétrica, e sucção pelo recém-nascido. O estudo teve como objetivo analisar os efeitos de cada etapa do protocolo na concentração sérica de prolactina, no volume de secreção láctea e na satisfação materna. A concentração sérica de prolactina e a produção láctea não apresentaram mudanças significativas. Entretanto, a mãe foi capaz de amamentar a criança por quatro semanas, e manifestou grande satisfação com a experiência. Como conclusão, no contexto de maternidade por útero de substituição, o aleitamento materno parece promover benefícios emocionais, não necessariamente relacionados ao aumento do volume de leite.

Effects of metoclopramide on the expression of metalloproteinases and interleukins in left colonic anastomoses. An experimental study

PURPOSE : To evaluate the effects of metoclopramide on metalloproteinases (MMP) and interleukins (IL) gene expression in colonic anastomoses in rats. METHODS : Eighty rats were divided into two groups for euthanasia on the 3rd or 7th postoperative day (POD), then into two subgroups for sepsis induction or not, and then into subgroups to receive either metoclopramide or saline solution. Left colonic anastomosis were performed and then analyzed. RESULTS : On the 3rd POD, metoclopramide was associated with increased expression of MMP-1a, MMP-13, and TNF-α. On the 7th POD, the transcripts of all MMPs, TNF-α, IL-1β, IFN-γ, and IL-10 of the treated animals became negatively modulated. In the presence of sepsis, metoclopramide did not change MMPs and decreased IL-6, IL-1β, IFN-γ and IL-10 gene expression on the 3rd POD. On the 7th POD, increased expression of all MMPs, IFN-γ and IL-10 and negative modulated TNF-α and IL-6 gene expression. CONCLUSION : Administration of metoclopramide increased metalloproteinases and interleukins gene expression on the 3rd postoperative day and negatively modulated them on the 7th POD. In the presence of abdominal sepsis, metoclopramide did not change MMPs and decreased ILs gene expression on the 3rd POD. On the 7th POD, the drug increased expression of all MMPs.

Influence of hyperprolactinemia on collagen fibers in the lacrimal gland of female mice

OBJECTIVE:To quantify the collagen fibers in the lacrimal gland of female mice with hyperprolactinemia.METHODS:Forty adult female mice were randomly divided into two groups with 20 animals each: nonpregnant control (CTR1, control group, 0.2 mL of saline solution) and nonpregnant experimental (HPRL1, experimental group, 200 µg/day metoclopramide). Treatments lasted for 50 consecutive days. On day 50, 10 females from each group (control and experimental) were euthanized in the proestrus phase; then, the blood was collected and the lacrimal glands were removed. Thereafter, the remaining females were placed with the mates and continued to receive treatment with saline solution or metoclopramide. On the 6th post-coital day, 10 pregnant females from the control group (CTR2) and 10 pregnant females from the experimental group (HPRL2) were euthanized, after which blood was collected and the lacrimal glands removed. The lacrimal glands were processed for morphological analyses and collagen quantification, and prolactin and sex steroid levels were measured in the blood samples. Data were statistically analyzed using an unpaired Student t test (p<0.05).RESULTS:Morphological analysis revealed greater structural tissue disorganization of the lacrimal glands in the metoclopramide-treated groups. The total collagen content was significantly higher in the HPRL1 group than in the CTR1 group (p<0.05), whereas the difference between the CTR2 and HPRL2 groups was not significant.CONCLUSION:Our data suggest an impairment in the functioning of the lacrimal gland as a consequence of increased prolactin levels and decreased serum levels of estrogen and progesterone.

Comparison of droperidol and ondansetron prophylactic effect on subarachnoid morphine-induced pruritus / Comparação dos efeitos profiláticos do droperidol e do ondansetron sobre o prurido provocado pela morfina subaracnoidea / Comparación de los efectos profilácticos del droperidol y del ondansetrón sobre el prurito provocado por la morfina subaracnoidea

El objetivo del presente trabajo es comparar el efecto del droperidol con el del ondansetrón sobre el prurito provocado por la morfina subaracnoidea.

Efectos extrapiramidales por metoclopramida en embarazo y recién nacido / Extrapyramidal effects for metoclopramide in pregnancy and newborn

Las náuseas y la emesis son complicaciones posoperatorias que pueden derivar en bronco aspiración, una situación clínica potencialmente fatal. Para su prevención, se usan medicamentos como la metoclopramida. Se presenta un reporte de caso de extrapiramidalismo por metoclopramida en el recién nacido y la madre. Es una reacción secundaria a un medicamento, clasificada como un evento serio y definitivo, de tipo A. Se requiere considerar el balance entre riesgo y beneficio de este medicamento en este tipo de condiciones, como también considerar otras medidas que eviten estos casos. El reporte de reacciones adversas a medicamentos es una actividad que contribuye al uso seguro de los medicamentos.

Postoperative nauseas and vomiting are complications that can lead to bronchoaspiration, a potentially fatal clinical event. Medications such as metoclopramide are used to prevent them. A case report of extrapyramidal signs in a newborn and mother metoclopramide is presented. It has been classified as a serious drug reaction, type A. The risk-benefit balance of this drug in such conditions should be considered as well as other measures to prevent such events. The reporting of adverse drug reactions is an activity that contributes to the safe use of medicines.

Analysis of agreement between Visual Analogue Scales (VAS) and numerical questions to assess perception of teratogenic risks in treatment with drugs and radiotherapy in women / Análise de concordância entre as escalas visual analógica (VAS) e questões numéricas para avaliar a percepção de riscos teratogênicos em tratamento com medicamentos e radioterapia em mulheres

To evaluate the agreement between Visual Analogue Scales (VAS) and numerical questions as a way of assessing the perception of teratogenic risk of treatment with drugs and radiotherapy. Methods: the sample comprised 144 pregnant and 143 non-pregnant women consecutively recruited at public health centers in Porto Alegre, in the State of Rio Grande do Sul, from February to August 2011. The perception of risk for congenital malformations in the general population and the perceptions of teratogenic risk for exposure to acetaminophen, meto-clopramide, misoprostol and radiotherapy were measured using VAS and numerical questions. The agreement between the results of the two techniques was tested using a Bland-Altman plot. Results: the medians for the perceptions measured using VAS were higher than those obtained using numerical questions for all variables. The perception of risk for acetaminophen showed the lower bias of the two techniques (bias=13.17; p<0.001) and exposure to radiotherapy, the higher (bias=25.02; p<0.001). Conclusion: there was no agreement between the measurements obtained using the two techniques for any of the risk perceptions under study. Risk perceptions were higher using VAS, for all kinds of exposure. Studies should be conducted to assess whether there is overestimation in other situations and social contexts owing to the use of VAS...

Avaliar a concordância entre Escalas Visuais Analógicas (EVA) e perguntas numéricas para aferir a percepção de risco teratogênico de medicamentos e radioterapia. Métodos: a amostra foi constituída por 144 gestantes e 143 não gestantes recrutadas consecutivamente em centros públicos de saúde de Porto Alegre, RS, entre fevereiro e agosto de 2011. A percepção de risco de malformações congênitas na população geral e as percepções de risco teratogênico das exposições a paracetamol, metoclo-pramida, misoprostol e radioterapia na gestação foram aferidas por EVA e perguntas numéricas. A concordância entre as duas técnicas foi avaliada pela análise gráfica de Bland-Altman Resultados: as medianas das percepções de risco teratogênico medidas por EVA foram superiores às obtidas através da pergunta numérica, para todas as variáveis. A percepção de risco ao paracetamol apresentou o menor viés entre as duas técnicas de aferição (viés=13,17; p<0,001) e a exposição à radioterapia, o maior (viés=25,02;p<0,001). Conclusões: não houve concordância entre as duas técnicas, para nenhuma das percepções de risco estudadas. As percepções de risco foram maiores para EVA, para todas as exposições. Sugerimos a realização de estudos que avaliem se também ocorre superestimação em outras situações e contextos sociais, em função do uso de EVA...

Effects of bromopride on expression of metalloproteinases and interleukins in left colonic anastomoses: an experimental study

Anastomotic dehiscence is the most severe complication of colorectal surgery. Metalloproteinases (MMPs) and interleukins (ILs) can be used to analyze the healing process of anastomosis. To evaluate the effects of bromopride on MMP and cytokine gene expression in left colonic anastomoses in rats with or without induced abdominal sepsis, 80 rats were divided into two groups for euthanasia on the third or seventh postoperative day (POD). They were then divided into subgroups of 20 rats for sepsis induction or not, and then into subgroups of 10 rats for administration of bromopride or saline. Left colonic anastomosis was performed and abdominal sepsis was induced by cecal ligation and puncture. A colonic segment containing the anastomosis was removed for analysis of gene expression of MMP-1α, MMP-8, MMP-13, IL-β, IL-6, IL-10, tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ). On the third POD, bromopride was associated with increased MMP-1α, MMP-13, IL-6, IFN-γ, and IL-10 gene expression. On the seventh POD, all MMP transcripts became negatively modulated and all IL transcripts became positively modulated. In the presence of sepsis, bromopride administration increased MMP-8 and IFN-γ gene expression and decreased MMP-1, TNF-α, IL-6, and IL-10 gene expression on the third POD. On the seventh POD, we observed increased expression of MMP-13 and all cytokines, except for TNF-α. In conclusion, bromopride interferes with MMP and IL gene expression during anastomotic healing. Further studies are needed to correlate these changes with the healing process.

Mecanismos de interacción entre el extracto etanólico de Jatropha curcas L. y metoclopramida en el sistema gastrointestinal / The mechanisms of interaction between the ethanol extract of Jatrohpa curcas L. and metoclopramide on gastrointestinal system

Objetivo: Determinar los mecanismos de interacción entre el extracto etanólico de Jatrohpa curcas L. y la metoclopramida sobre el sistema gastrointestinal. Material y Métodos: Se usó 30 ratones albinos machos, en5 grupos; los que recibieron por vía oral: Grupo 1: Jatropha curcas L. 800 mg/Kg, y 0, 5mg/Kg de metoclopramida. Grupo 2: 0.5 mg/mL de metoclopramida. Grupo 3: 1.5 mg/Kg de Atropina. Grupo 4: 800 mg/kg de Jatropha curcas L. Grupo 5: no recibió medicamento. A todos, se les administró por vía oral: carbón activado al 5% 0,1 mL/10g, como marcador intestinal. Se empleó el Método Arboset al, para evaluar la motilidad intestinal. La validación estadística del recorrido intestinal se realizó aplicando las pruebas de Kolmogorov Smirnov, ANOVA de 1 cola, Tukey y Newman-Keuls. Resultados: Se observó un el porcentaje de recorrido del carbón de 36.46% del grupo 1 frente a 65,45%, 3,66% y 58,87% de los grupos 2, 3 y 4, respectivamente; y de 58,87% del grupo 4 frente a 20,94% del grupo 5. Conclusiones: Se evidenció el antagonismo entre el extracto etanólico de la semilla de Jatropha curcas L. con la metoclopramida, el cual se explicaría por la interacción entre el sistema colinérgico, adrenérgico, GABAérgico y de neuropéptidos sobre la glándula suprarrenal, sistema nervioso central y gastrointestinal.

Objective: Determinate the mechanisms of interaction between the ethanol extract of Jatrohpacurcas L. and metoclopramide on gastrointestinal system. Material and Methods: 30 male albino mice were used, forming 5 groups and received oral medications as follows: Group 1: Jatropha curcas L. 800 mg / kg, and 0.5 mg/Kg of metoclopramide. Group 2: 0.5 mg/mL of metoclopramide. Group 3: 1.5 mg/Kg of atropine. Group 4: 800 mg/Kg of Jatropha curcas L. Group 5 received no medication. All groups receivedoral activated charcoal 0.1 mL/10g as intestinal marker. The Arbos et al method was used to evaluate intestinal motility. The statistical validation of the intestine dynamics was performed using the Kolmogorov Smirnov, 1-tailed ANOVA, Tukey and Newman-Keuls. Results: the percentage of charcoal runs in the 1rst group was 36.46% compared to 65.45%, 3.66 % and 58.87% for the 2nd, 3th and 4th groups, respectively. In the 4th group was 58,87% compared to 20.94% in the 5th group. Conclusions: the antagonism between the ethanol extract of the seeds of J.curcas L. with metoclopramide, which is probably would explain by the interaction between the cholinergic system, adrenergic system, GABAergic system and neuropeptides on the adrenal gland, central nervous system and gastrointestinal system.
