An observational study to evaluate the awareness of drug treatment, prescription pattern, adverse drug reactions, and adherence in patients of major depressive disorder.

Aims: Due to the paucity of studies in and out of India that dealt with treatment awareness of major depressive disorder (MDD), we decided to assess the awareness of MDD patients, and since adherence and awareness are linked to each other, we assessed adherence too. Prescription pattern studies identify changes in prescriptions due to poor initial response or adverse drug reactions (ADRs), which may result in dose reduction or switching medications and delay remission. Therefore, the study assessed the ADR pattern. Methodology: A cross-sectional questionnaire-based study was carried out on 200 MDD patients with treatment records for at least 3 months after getting approval from the Institutional Ethics Committee and consent from the patients. The data obtained were entered in Microsoft Excel and analyzed using descriptive statistics. Results: The mean age was 44.65 ± 12.02 years, and females were 70%. Maximum patients (98%) were aware of the consequence of stopping the drugs suddenly, and only 12.5% were aware of the onset of response to treatment. Escitalopram was the most common antidepressant prescribed (43.77%), and 67 ADRs out of 136 were attributable to it. Weakness and fatigue were the most common ADRs. The majority (97) of the ADRs were possibly related to antidepressants, and 65% of patients showed optimal adherence to medications. Conclusions: This study sheds light on the treatment awareness and adherence of MDD patients in India and highlights the need for educating patients about treatment response. It also emphasizes the importance of monitoring ADRs and adjusting prescription patterns accordingly to improve treatment outcomes.

Evaluation of factors that act as barriers in conducting academic trials - An investigator's perception.

Background: Academic trials are essential in investigating health research questions relevant to the society. Only a few leading research institutions in India have been engaged in academic trials. Thus, there is a need to understand what factors dampen the spirit of the academician in conducting academic clinical trials. Aims and Objectives: The aim of the study is to evaluate the investigator's perception of obstacles to carrying out academic trials and to identify factors that will motivate investigators in conducting academic trials. Materials and Methods: We conducted a prospective observational study in a tertiary care hospital for 6 months. Faculty members working in academic institutes were selected. A structured questionnaire was designed for the study and administered using google forms. Responses were taken on a Likert scale. Validity and reliability assessments were carried out. Mann-Whitney test was applied to assess differences between demographic groups. P <0.05 was considered significant. Results: Most of the participants rated applying for research grants (76%), obtaining funding for the study and making arrangements for compensation for trial-related events (75%) as extremely challenging. We found that the degree of challenge is significantly lower in the faculty members who conducted clinical trials in the past as against those who did not (P = 0.00069). We also found that the degree of challenge is significantly higher in the faculty members with <10 years of experience than those with >10 years of experience (P = 0.00001). Conclusion: Thus, to conclude the challenges faced by investigators were at multiple levels, most common being applying for research grants and making arrangements for the funds for payment towards participation or study-related injury. Faculty members with exposure to conducting clinical trials and with experience of more than 10 years had perceived a reduced degree of challenges.

A Retrospective Study of Ethics Committee Monitoring Checklists of the Audiovisual Consent Process: An Ethical Perspective.

Clinical trial regulations for new drugs in India released a gazette notification for obtaining audiovisual (AV) consent from all trial participants in November 2013. The reports of AV recordings of the studies from October 2013 to February 2017 submitted to the institutional ethics committee were analyzed in view of the Indian regulations on AV consenting. The reports of AV recording were checked: number of AV consents for each project, adequacy of AV recording, number of persons in the video, informed consent document elements (ICD) covered as per Schedule Y, confirmation of understanding by the participant, the time taken to complete the procedure, maintenance of confidentiality, and whether reconsent was taken. Seven studies of AV consent were monitored. Eighty-five (85) AV-consented and filled checklists were evaluated. The AV recording was not clear in 31/85, ICD elements were missing in 49/85 consents, time taken to complete the procedure was 20.03 ± 10.83 with the number of pages being 14.24 ± 7.52 (R= 0.29 p<0.041). In 19/85 consents, privacy was not maintained and on 22 occasions, reconsent were taken. There were deficits found in the AV consent process.

Association of funding and conflicts of interest on outcomes reported in published studies of Covid-19.

BACKGROUND: An outbreak of the Covid-19 has led to substantial mortality globally. The entire world is carrying out studies to understand the pathophysiology, clinical features, diagnosis and treatment of Covid-19. We investigated the possible association of type of funding, corporate or academic, and conflict of interests on the outcomes reported in clinical trials on Covid-19. METHODS: Studies containing the keywords "clinical trial" AND "Covid 19" or "Corona" were located by a search on PubMed published between September 2019 to August 2021. Filters were used to select only papers in the English language and on "humans". The data were analysed using descriptive statistics and the Chi-square test. RESULTS: We found a significant association between the existence of a conflict of interest and reporting of a positive outcome (X2 value = 18.751, p less than 0.001). We also found a significant association between industry funding and reporting of a positive outcome (X2 value = 18.041, p less than 0.001). CONCLUSION: We conclude from this study that the presence of conflict of interest and pharmaceutical industry funding is associated with reporting a positive outcome.

S-adenosyl methionine improves motor co-ordination with reduced oxidative stress, dopaminergic neuronal loss, and DNA methylation in the brain striatum of 6-hydroxydopamine-induced neurodegeneration in rats.

PURPOSE: Parkinson's disease (PD) is the most common age-related neurodegenerative disease worldwide. S-adenosyl methionine (SAMe), a methyl donor that plays an important role in DNA methylation, could replenish the cellular antioxidant glutathione (GSH). Herein, we investigated the neuroprotective effects of SAMe in 6-hydroxydopamine (6-OHDA) rat models of PD and elucidated the underlying mechanism. METHODS: PD model rats were developed by injecting 6-OHDA stereotaxically into the striatum. In Phase 1 of the study, we performed the neurobehavioral tests, GSH assay, and histopathology to evaluate the neuroprotective effects of SAMe. The animals were treated with SAMe (150 or 300 mg/kg body weight) orally for 28 days. The positive control group received selegiline (5 mg/kg), whereas the disease control group received normal saline. In Phase 2, we evaluated the striatal dopamine levels and performed DNA methylation assay to uncover the mechanism of action of SAMe. In this phase, a higher dose of SAMe (300 mg/kg) was used. RESULTS: SAMe (300 mg/kg) treatment for 4 weeks significantly attenuated the abnormal circling behavior in PD rats (p < 0.05). Moreover, SAMe at both doses (150 and 300 mg/kg) enhanced the performance of PD rats in the open field test and stepping test (p < 0.05). SAMe treatment significantly increased the GSH levels, and at high dose, SAMe restricted neuronal loss in the striatum of PD-model rats (p < 0.05). Moreover, SAMe treatment led to a significant recovery in the dopamine levels and improved the DNA methylation status in the dopaminergic neurons (p < 0.05) of PD model rats. CONCLUSION: SAMe exhibits antioxidant activity and DNA methylation modulating effects in 6-OHDA model PD rats. Moreover, SAMe prevents neuronal loss in PD rats suggesting that SAMe has therapeutic potential in preventing PD development. The neuroprotective potential of SAMe is greater at high doses.

Evaluation of Antidepressant Effect of Minocycline in Alcohol Abstinence-Induced Depression Model in Mice.

Introduction Depression is one of the common comorbidities seen in chronic alcohol use disorder. Also, alcohol withdrawal induces depression and anxiety, which is associated with relapse in alcohol consumption. Minocycline, a tetracycline derivative, has shown an antidepressant effect in preclinical models. However, their effect on alcohol withdrawal-induced depression has not been studied. Therefore, the current study has been undertaken to evaluate the effect of minocycline on alcohol abstinence-induced depression models in mice. Method We conducted the study in two models. C57bl/6 mice were given a two-bottle choice (alcohol + water) for 28 days. During alcohol abstinence of 14 days, mice were treated with 10 mg/kg, 30 mg/kg, and 50 mg/kg of minocycline and were evaluated for behavioral changes using the forced swim test (FST) and tail suspension test (TST). A sucrose preference test was carried out where mice were exposed to binge alcohol drinking protocol for 12 days, where a two-bottle choice (alcohol or water) was given. This was followed by exposing the mice to a two-bottle choice paradigm (alcohol + sucrose) and they were divided into groups - no treatment group, vehicle-treated, minocycline 30 mg/kg or minocycline 50 mg/kg treated - and consumption of sucrose was assessed. Result In the forced swim test, a significant decrease in immobility time (p<0.05) was observed in the high-dose minocycline group (82.75±19.09) as compared to the vehicle control group (128.12±35.44). In the tail suspension test also, a significant decrease in immobility time (p<0.05) was seen in the high-dose minocycline group (83.75±18.61) as compared to the vehicle control group (122.25±18.51). The water and alcohol intake were comparable among all groups. In the sucrose preference test, it was found that the minocycline 50 mg/kg group had the highest sucrose preference (55%) followed by the minocycline 30 mg/kg group (50%) as compared to 42% in the vehicle control group. Significant reduction in brain-derived neurotrophic factor (BDNF) levels was seen with minocycline 50 mg/kg (p<0.05) and minocycline 30 mg/kg group (p<0.05) in BDNF levels when compared to the normal control group. Conclusion Minocycline in a higher dose (50 mg/kg) has shown an effect in alcohol withdrawal-induced depression in the abstinence-induced two-bottle choice model in mice. Both doses of minocycline have shown an effect in the sucrose preference test in the alcohol withdrawal-induced depression model.

A Cross-Sectional, Questionnaire-Based Study on Drug Treatment Awareness in Schizophrenia Patients and Caregivers: An Unexplored Avenue.

Background: Schizophrenia is associated with high relapse rates, and medication nonadherence is a major factor contributing toward relapse. Since medication adherence and treatment awareness are linked, an alarming need was felt to evaluate the level of drug treatment awareness in patients who have schizophrenia. Besides, patients who have schizophrenia are often dependent on their caregivers for medications. Hence, the current study was also designed to look into drug treatment awareness among caregivers. Methods: This was a cross-sectional, questionnaire-based study. Patients diagnosed with schizophrenia as per The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition were included, provided they had good insight and had been prescribed medications at the study center for at least three months. Caregivers were included using the Pollak and Perlick criteria. The sociodemographic profile of the patients and caregivers was recorded, and further assessment for treatment awareness was done using the prevalidated Drug Treatment Awareness Questionnaire (DTAQ). Results: A total of 166 patients and 157 caregivers were enrolled. Mean drug awareness scores among patients and caregivers did not show statistically significant differences (P= 0.22). Mean ± SD DTAQ awareness scores in patients and caregivers were 12.57 ± 1.81 and 12.84 ± 1.91, respectively. The majority of patients and caregivers (> 90%) possessed awareness in domains related to past medication records and in that of re-visit/re-contact instructions. Awareness was least commonly seen in relation to side effects of medications and details of the prescribed medications, where only about 50% of patients and caregivers possessed awareness. No clinically significant correlation was found between sociodemographic factors and drug treatment awareness scores. Conclusion: Drug treatment awareness in patients and caregivers was comparable and was not reliant on the sociodemographic factors. Special interventions should be conducted to raise drug treatment awareness among patients having insight and their caregivers.

Antipsychotic Drug Utilization and Adverse Drug Reaction Profiling in Patients With Schizophrenia at a Tertiary Care Hospital in Western India.

Introduction Prescription pattern studies conducted in patients with schizophrenia have shown variability in the utilization of antipsychotics based on the geographical location of the study setting. Moreover, there is only a sparse number of studies specifically related to adverse drug reactions (ADRs) in schizophrenia. Hence, a need was felt to study the antipsychotic utilization pattern and adverse drug reactions in patients with schizophrenia in our setting. Methods This was a cross-sectional, observational study conducted at the psychiatry outpatient department (OPD) of a tertiary care hospital in India. Patients diagnosed to have schizophrenia as per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) were included in the study provided they had been prescribed antipsychotic medications at the study center for at least three months. The sociodemographic profile of the patients and caregivers was recorded, and prescription pattern assessment was done using WHO core drug use indicators. Information related to ADRs was recorded, and further assessment was done based on the causality, severity, and preventability of ADRs. Results A total of 250 patients were enrolled in the study. Risperidone (40.25%) and olanzapine (26.32%) were the most commonly prescribed antipsychotic drugs, while trihexyphenidyl was the most frequently prescribed concomitant medication. Among the 37 cases of adverse drug reactions that were recorded, amenorrhea, sedation, and weight gain were found to be the most common. The majority of ADRs were of mild severity in addition to being non-preventable. Conclusion It was observed that atypical antipsychotics were commonly prescribed in the study center, and the majority of the ADRs were mild and not preventable, which shows the adequacy of prescribing practices in the current setting.

Critical appraisal of published research papers - A reinforcing tool for research methodology: Questionnaire-based study.

BACKGROUND AND OBJECTIVES: Critical appraisal of published research papers is routinely conducted as a journal club (JC) activity in pharmacology departments of various medical colleges across Maharashtra, and it forms an important part of their postgraduate curriculum. The objective of this study was to evaluate the perception of pharmacology postgraduate students and teachers toward use of critical appraisal as a reinforcing tool for research methodology. Evaluation of performance of the in-house pharmacology postgraduate students in the critical appraisal activity constituted secondary objective of the study. MATERIALS AND METHODS: The study was conducted in two parts. In Part I, a cross-sectional questionnaire-based evaluation on perception toward critical appraisal activity was carried out among pharmacology postgraduate students and teachers. In Part II of the study, JC score sheets of 2nd- and 3rd-year pharmacology students over the past 4 years were evaluated. RESULTS: One hundred and twenty-seven postgraduate students and 32 teachers participated in Part I of the study. About 118 (92.9%) students and 28 (87.5%) faculties considered the critical appraisal activity to be beneficial for the students. JC score sheet assessments suggested that there was a statistically significant improvement in overall scores obtained by postgraduate students (n = 25) in their last JC as compared to the first JC. CONCLUSION: Journal article criticism is a crucial tool to develop a research attitude among postgraduate students. Participation in the JC activity led to the improvement in the skill of critical appraisal of published research articles, but this improvement was not educationally relevant.

An Evaluation of the Efficacy, Safety, and Tolerability of Abhraloha Compared With Oral Ferrous Ascorbate on Iron Deficiency Anemia in Women: A Randomized Controlled, Parallel-Group, Assessor-Blind Clinical Trial.

Background and objective Iron deficiency anemia (IDA) is a common condition in women for which ferrous ascorbate (FA) is often prescribed, which can lead to multiple side effects. Abhraloha is an Ayurvedic medicine that has been used for decades in India to treat IDA. In this study, we aimed to evaluate the efficacy and safety of Abhraloha with regard to change in hemoglobin (Hb) levels as compared to the standard treatment using FA in participants with IDA. Materials and methods We conducted a single-center, pragmatic, prospective, randomized, active-controlled, two-arm, parallel-group, assessor-blind study to evaluate the efficacy and safety of Abhraloha with regard to change in Hb levels as compared to the standard treatment using FA in participants suffering from IDA. The eligible participants were randomized and were advised to take either Abhraloha (two tablets twice a day) or FA (one tablet twice a day) for eight weeks; they were asked to follow up after 14 days for re-evaluation. On visit 1 and during the study period, the physician assessed the participants on the Pandurog scale and subjective variables. Descriptive statistics were used with unpaired T-test/Mann-Whitney U test for comparison between the groups. The Wilcoxon signed-rank test was used for within-group analysis, and the chi-square test/Fisher's exact test was employed for categorical data. Results Based on our findings, Abhraloha tablets significantly increased all the variables including the Pandurog scale after eight weeks of treatment. Abhraloha reduced total iron-binding capacity (TIBC) and peripheral smear lymphocyte (PSL), which is consistent with an improvement in IDA. There was a statistically significant increase in Hb, red blood cell (RBC) count, packed cell volume (PCV), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) in the Abhraloha group as compared with the FA group at eight weeks. The Abhraloha group also exhibited a statistically significant improvement in all the subjective variables. Abhraloha was found to be safe and well-tolerated among the participants. Conclusions Abhraloha possesses hematinic activity and it improves all the blood indices. It is associated with significantly fewer adverse effects compared to oral iron therapy, which proves that it can be safely used for the treatment of IDA.

Assessing completion reports for compliance with institutional ethics committee-approved protocols: An observational study.

BACKGROUND: Protocol non-compliance in clinical research studies is common and can affect both patient safety and data integrity. There are no published studies which actively looked for non-compliance. The present study was carried out, against this background, with the objective of assessing the proportion of protocol non-compliance and evaluating those aspects of protocol where there was non-compliance. METHODS: The study completion reports that were submitted to the institutional ethics committee for the period January 2017 to December 2017 were compared with the approved protocol. A checklist for recording protocol non-compliance was developed, which was validated by five experts and consisted of a 12-point checklist with responses such as yes, no, not applicable, and insufficient information. RESULTS: Out of 193 studies, prospective observational studies were n = 120 (62.17 %), retrospective studies were n = 39 (20.21%), interventional studies n = 28 (14.51 %), and observational studies with both prospective and retrospective study design were n = 6 (3.11%). The study objective was modified in n=18 (9.32%) studies. Only n = 14 (7.24%) satisfied the selection criteria. Six studies (3.10%) did not collect the data as mentioned in the protocol. Fifty-eight studies (30.05%) did not achieve the calculated sample size, whereas n = 78 (40.41%) did not complete the study as per the stipulated study duration. Contrary to 180 protocol deviations found in this study, only 14 protocol deviations were reported by the principal investigator. Aspects like blinding and randomisation, which are relevant to interventional studies (n = 28), showed 100 % compliance. CONCLUSION: The research protocol is not adhered to in all aspects. Adequate training to investigators will help prevent non-compliance and enable us to conduct studies with higher ethical and scientific integrity.

Reports of site monitoring visits by institutional ethics committees in an Indian tertiary care hospital: A retrospective analysis.

The monitoring of clinical trials is an integral function of the institutional ethics committee (IEC)to ensure the ethical conduct of research. The National Ethical Guidelines for Biomedical and Health Research Involving Human Participants, 2017, of the Indian Council of Medical Research, underline a strong need for active monitoring of clinical trials. A previous study by the authors, of research studies initiated between 2008 and 2010, had found many lapses after site monitoring. In the present study, 12 clinical studies-both sponsored and investigator initiated-were monitored by members of the King Edward Memorial Hospital (Mumbai) IEC between 2011 and 2017. The most common violations seen were related to informed consent (8/12 sites). The other violation themes were lack of investigator understanding of protocol (6/12), deviation from the investigational plan (5/12), non-reporting of the study's progress to the IEC (4/12), and patient recruitment prior to IEC approval (2/12). The IEC took various corrective actions, such as ordering retaking of consent and good clinical practice (GCP) re-training and requiring interim reports, explanations for deviations, upgradation of facilities, and payment of pending compensation. The IEC even froze review of protocols from a frequently defaulting Principal Investigator's (PI) site and put study recruitment on hold for the same PI. This study demonstrates that active site monitoring by IECs is a must for ensuring the ethical conduct of studies.

Perception of postgraduate students in pharmacology toward animal simulation model.

OBJECTIVE: The objective of the study is to evaluate the perception of postgraduate pharmacology students toward computer-simulated method (CSM) in comparison to the prevalent isolated live tissue-based bioassay method. MATERIALS AND METHODS: A questionnaire-based survey was conducted in 30 postgraduate pharmacology students who had used the animal simulation software and had completed at least five isolated tissue experiments. Students' opinions on the usage, logistics, advantages, disadvantages, and usefulness of CSM compared to live animal experiments (LAE) were analyzed. RESULTS: Four tissues were used for LAE, whereas with CSM, students could perform experiments using 11 different tissues. Of the total nine bioassay methods, students had performed six assay methods using both LAE and CSM. Majority of the students (23/30) agreed that CSM reduces anxiety, technical errors and is less time consuming when used before LAE. Most of the students agreed that CSM can be used for difficult, lengthy experiments (19/30), and for UG/PG teaching (19/30). However, opinions regarding replacing LAE with CSM in PG teaching were divided (agree: 7, neutral: 12, and disagree: 12). CONCLUSION: CSM should be integrated alongside LAE to complement, reinforce, and enhance learning from other techniques.

Minocycline in Alcohol Withdrawal Induced Anxiety and Alcohol Relapse in Rats.

INTRODUCTION: Anxiety and negative sensations due to alcohol withdrawal are factors leading to alcohol relapse and addiction. Minocycline, an antibiotic, can decrease alcohol consumption in rats, however, its effects on alcohol withdrawal anxiety and relapse have not been studied. MATERIAL AND METHODS: Part 1: Forced alcohol drinking in gradually increasing concentration was administered till day 22 in rats. Effect of drugs on anxiety was assessed using elevated plus maze (EPM) and two-chambered box apparatus, after removal of alcohol. Part 2: For relapse, an alcohol deprivation effect model was used, rats were continuously offered alcohol and water for 4 consecutive weeks in a two-bottle choice paradigm, followed by 2 weeks of alcohol deprivation. Effect of drugs on alcohol consumption during the first hour of alcohol reintroduction was assessed. Animals were sacrificed and whole brain Tumor Necrosis Factor (TNF) α was estimated. RESULTS: Part 1: Anxiety at 3 hours was significantly lower following minocycline (20 mg/kg i.p.) or diazepam compared to vehicle control. Part 2: Acute administration of minocycline (5,10 and 20 mg/kg, i.p.) suppressed alcohol consumption significantly (p value<0.05) as compared to vehicle control. A significant decrease in whole brain TNF α was observed in animals treated with minocycline compared to untreated animals. CONCLUSION: Minocycline attenuates alcohol withdrawal anxiety and disrupts alcohol relapse.

Evaluation of effect of minocycline on rewarding potential and alcohol relapse in place preference model in mice.

INTRODUCTION: Medical management for alcohol abuse has limitations. Alcohol consumption activates N-methyl-d-aspartate receptors and release of nitric oxide which can be inhibited by minocycline as it readily crosses blood brain barrier and may have effect on alcohol consumption. Thus, study objective is to evaluate the effect of minocycline on rewarding property, extinction and the reinstatement phenomenon induced by alcohol in a model of conditioned place preference (CPP) in mice. METHODOLOGY: To evaluate rewarding effects of alcohol, CPP procedure consisted of 4 parts, including adaptation (day 1), pre-conditioning test (day 2), conditionings with alcohol (days 3, 5, 7 and 9) or saline (days 4, 6, 8 and 10) and postconditioning test (day 11) conducted on 11 consecutive days. The groups included were saline treated group (alcohol control), naltrexone - 1mg/kg (positive control), and minocycline in the doses of 10, 30 and 50mg/kg. To evaluate the effect of minocycline on alcohol relapse, CPP procedure consisted 6 parts, the first 4 were the same as enumerated above followed by extinction (days 12-16) and reinstatement phase (day 17). RESULTS: The time spent in alcohol paired compartment by different groups, revealed that minocycline and naltrexone significantly attenuated alcohol-induced place preference compared to alcohol control (p<0.05). Pretreatment with minocycline and naltrexone blocked reinstatement of extinguished CPP. CONCLUSION: Minocycline may have a role in attenuating the rewarding property of alcohol and prevent alcohol relapse.

Evaluation of antiepileptic effect of S-adenosyl methionine and its role in memory impairment in pentylenetetrazole-induced kindling model in rats.

BACKGROUND: Epilepsy is the third most common cause of neurological disability worldwide. Despite the introduction of antiepileptic drugs (AEDs) in the past 20years, the seizures of around 30% of patients with epilepsy remain refractory to available treatment. Also, available AEDs and the disease itself have the potential to exert detrimental effects on cognitive function and therefore compromise patient wellbeing. S-adenosyl methionine has potential antiepileptic and memory-enhancing properties because of its involvement in the transmethylation reaction. OBJECTIVES: The present study was designed to evaluate the antiepileptic effect of S-adenosyl methionine and its role in memory impairment in the pentylenetetrazole (PTZ)-induced kindling model in rats. MATERIALS AND METHODS: The antiepileptic effect of 2 doses of SAM (50 and 100mg/kg) was tested by evaluating seizure severity score and seizure latency in the pentylenetetrazole-induced kindling model in rats. At the end of the study, spatial memory was evaluated in an elevated plus maze (EPM) test, and animals were sacrificed for estimation of oxidative stress markers in brain tissue homogenate. RESULTS: A higher dose of SAM (100mg/kg) exhibited an increase in seizure latency and a decrease in seizure severity score, suggesting its antiepileptic activity in the PTZ-induced kindling model. Also, the administration of SAM (50 and 100mg/kg) showed a decrease in transfer latency in the EPM test compared to the disease control group (p<0.0001). Biochemical analysis of rat brain tissue revealed significantly decreased malondialdehyde (p<0.0001) and increased glutathione (GSH) (p<0.0001) in the SAM 100-mg/kg group compared with that in the disease control group. CONCLUSION: The results demonstrated that S-adenosyl methionine exerts antiepileptic, memory-enhancing, and antioxidant properties in a pentylenetetrazole-induced kindling model of epilepsy.

Evaluation of effects of Mandurabhasma on structural and functional integrity of small intestine in comparison with ferrous sulfate using an experimental model of iron deficiency anemia.

BACKGROUND: The present study was planned to assess effects of Mandurabhasma (MB) on structural and functional integrity of small intestine using an animal model of iron deficiency anemia (IDA) in rat. METHODS: IDA was induced by giving iron deficient diet and retro-orbital bloodletting for 21 days in Wistar female rats. Rats (n = 72) were divided into six groups: (i) Control group, (ii) IDA rats, (iii) IDA rats receiving vehicle, (iv) rats receiving ferrous sulfate (40 mg/kg), (vi) rats receiving a low dose (22.5 mg/kg) of MB, (vi) rats receiving a high dose (45 mg/kg) of MB. Treatment was conducted for a period of 21 days followed by an assessment of change in hemoglobin (Hb) levels, lactase levels, lipid peroxidation activity by measuring malondialdehyde (MDA) levels and jejunal morphometry. RESULTS: In the present study, the lactase activity was markedly reduced in iron-deficient rats. Our study has demonstrated that intestinal morphology and MDA levels were not altered in the animals with IDA as compared to normal animals. In phase II, improvement in Hb response to ferrous sulfate was accompanied by an improvement in lactase activity. However, it significantly increased MDA levels with derangement of the normal villous structure. Rats receiving a low dose of MB did not have increased MDA levels. It did not alter the jejunal villous structure and improved lactase activity, but hematinic activity was found to be less than that of ferrous sulfate. Rats receiving a high dose of MB showed significantly improved Hb as well as lactase levels. They exhibited damage to the villous structure and increased MDA levels, but the effects were significantly less as compared to ferrous sulfate group. CONCLUSION: Rats receiving a high dose of MB have shown improvement in hematinic and lactase levels comparable to those receiving ferrous sulfate. However, it causes lesser oxidative damage as compared to ferrous sulfate. This is an encouraging finding because it indicates the potential of MB to cause lesser gastrointestinal side effects compared to ferrous sulfate.

Drug utilisation and off-label use of medications in anaesthesia in surgical wards of a teaching hospital.

BACKGROUND AND AIMS: When a drug is used in a way that is different from that described in regulatory body approved drug label, it is said to be 'off label use'. Perioperative phase is sensitive from the point of view of patient safety and off-label drug use in this setup can prove to be hazardous to patient. Hence, it was planned to assess the pattern of drug utilisation and off-label use of perioperative medication during anaesthesia. METHODS: Preoperatively, demographic details and adverse events check list were filled from a total of 400 patients from general surgery, paediatric surgery and orthopaedics departments scheduled to undergo surgery. The perioperative assessment form was assessed to record all prescriptions followed by refilling of adverse events checklist in case record form. World Health Organization (WHO) prescribing indicators were used for analysis of drug utilisation data. National Formulary of India 2011 was used as reference material to decide off-label drug use in majority instances along with package insert. RESULTS: A total of 3705 drugs were prescribed to the 400 participants and average number of drugs per patient was 9.26 ± 3.33. Prescriptions by generic name were 68.07% whereas 85.3% drugs were prescribed from hospital schedule. Off-label drugs overall formed 20.19% of the drugs prescribed. At least one off-label drug was prescribed to 82.5% of patients. Inappropriate dose was the most common form of off-label use. There was 1.6 times greater risk of occurrence of adverse events associated with the use of off-label drugs. CONCLUSION: Prescription indicators were WHO compliant. Off-label drug use was practiced in anaesthesia department with questionable clinical justification in some instances.
