RESUMO

Background: Hospital pharmacists can play an important role in the detection, prevention, and reporting of adverse drug reaction (ADR) since they interact with patients in hospital settings. The ADR reporting practice by Pharm D students, who represent the future hospital pharmacists, has not been adequately investigated in the literature. Objective: To evaluate Pharm D students' knowledge, attitude, and practice regarding ADR reporting, and the associated barriers and motivators to ADR reporting during clinical training at different hospital sites in Jordan. Methods: The present cross-sectional study was conducted on sixth year pharm D students during clinical training at different hospital departments in different hospital sites Jordan. In addition to socio-demographic variables, a structured self-reported questionnaire was used to assess students' knowledge, attitude, practice, barriers, and motivators towards ADR reporting. Binary logistic regression was used to explore the variables associated with the study outcomes. Results: A total of 497 students participated in the study. The participants showed inadequate knowledge regarding ADR reporting, with a mean knowledge score of 3.20 (±1.78). On the other hand, the study participants showed positive attitude towards ADR reporting with a total mean score of 13.6 (±1.96). However, the ADR reporting practice was low with a mean score of 5.78 (±1.88). Not knowing how to report (60.2%) and not knowing where to report (55.9%) were the most common barriers to ADR reporting, while the most reported motivators for ADR reporting were seriousness of reaction (84.1%) and involvement of new drug (51.1%). Logistic regression analysis showed that time from the start of training (OR = 0.510; 95%CI = 0.305-0.852; P = 0.010), female gender (OR = 1.759; 95%CI = 1.083-2.857; P = 0.022), and attending a course/workshop about pharmacovigilance (OR = 0.213; 95%CI = 0.137-0.332; P = 0.00) were significant predictors of knowledge about ADR reporting. Increased age (OR = 0.93; 95%CI = 0.880-0.997; P = 0.041) and low knowledge (OR = 0.564; 95%CI = 0.380-0.837; P = 0.004) were significantly associated with negative attitude toward ADR reporting. Female gender (OR = 0.481; 95%CI = 0.302-0.766; P = 0.002) and attitude level (OR = 1.837; 95%CI = 1.205-2.802; P = 0.005) were significant predictors of ADR reporting practice. Conclusions: Pharm D students showed positive attitude towards ADR reporting, however, the knowledge and practice of ADR reporting were inadequate and the participants reported several barriers. Therefore, the topic of ADR reporting and pharmacovigilance, as well as, educational training programs need to be included in future pharmacy curriculum in order to improve students' awareness and practice of ADR reporting.

RESUMO

A series of N-(benzoylphenyl)-carboxamide derivatives (2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a and 6b) was prepared with good yields by reacting the corresponding carbonyl chlorides with aminobenzophenones at room temperature. This was followed by evaluating the hypotriglyceridemic and hypocholesterolemic effects of 3b, 5a and 5b. Triton WR-1339 (300 mg/kg) was intraperitoneally administered to overnight-fasted rats to induce hyperlipidemia. Rats were divided into six groups: control, hyperlipidemic, hyperlipidemic plus compounds 3b, 5a and 5b and hyperlipidemic plus bezafibrate. Results showed that after 18 h of treatment at a dose of 15 mg/kg body weight of each of the test compounds, the elevated plasma levels of triglycerides (TG) and total cholesterol (TC) were significantly lowered by compounds 5b and 3b (p < 0.001) and by 5a (p < 0.0001), compared to the hyperlipidemic control group. Compounds 3b and 5a significantly increased levels of high-density lipoprotein cholesterol (HDL-C) by 58 and 71%, respectively. In addition, compounds 3b and 5a caused significant reduction (p < 0.0001) of low-density lipoprotein cholesterol (LDL-C) levels compared to the control group. These results suggest a promising potential for compounds 3b, 5a and 5b as lipid-lowering agents, which may contribute to reducing the risk of atherosclerosis and cardiovascular disease

RESUMO

A new series of imidazole-5-carboxamide derivatives were prepared and tested for their anti-hyperlipidemic activity in Triton-WR-1339-induced hyperlipidemic Wistar rats. The purpose of this research was to improve benzophenone carboxamides water solubility maintaining at the same time the antihyperlipidemic activity. Compounds 4, 6, 10, and 11 were synthesized through a coupling reaction between imidazoles-5-carbonyl chloride and amino benzophenones. The tested animals (n=48) were divided into six groups: the first group (hyperlipidemic control group; HCG) received an intraperitoneal injection (i.p.) of (300 mg/kg) Triton WR-1339. The second group received i.p. injection of Triton WR-1339 followed by an intra-gastric administration of bezafibrate (100 mg/kg) (bezafibrate; BF). The third, fourth, fifth, and sixth groups received i.p. injection of Triton WR-1339 followed by an intra-gastric administration of (30 mg/kg) of compounds 4, 6, 10, and 11, respectively. At a dose of 30 mg/kg body weight compounds 4, 6, 10, and 11 significantly (p<0.0001) decreased the plasma level of triglyceride (TG), low-density lipoprotein (LDL) and total cholesterol (TC) levels after 18 h of treatment. Additionally, compounds 4, 6, 11 and bezafibrate (100 mg/kg) significantly (p<0.0001) increased the plasma level of high-density lipoprotein (HDL) levels, which is known for its preventive role against atherogenesis. These results demonstrate the possibility of pharmacokinetic properties improvement maintaining the biological and pharmacological profile of these compounds.

RESUMO

Hyperlipidemia is a known cause of coronary vascular diseases, which is a major cause of death in many parts of the world. Targeting several pathways that lead to increase in lipid profiles is of great potential to control diseases. 1H-indole-2-carboxamide derivatives were tested for their hypolipidemic activity at the molecular level in comparison with bezafibrate. The gene expression profiles of lipoprotein signaling and cholesterol metabolism and fatty acid metabolism PCR arrays were determined in rats with acute hyperlipidemia induced by Triton WR1339. Lipid profiles of serum from treated rats showed significant hypolipidemic effect by the compounds. Several genes of potential interest were reported to be overexpressed by Triton WR1339 including Apoc3, Apob, Hmgcs2, Apoa1, Apoe, Apof, acsl1, and Decr1. Most of the overexpressed genes were downregulated by N-(3-Benzoylphenyl)-1H-Indole-2-Carboxamide with significant decreases in Apoc3, Apob, Acaa2, Acsl1, and Slc247a5 gene expression levels. N-(4-Benzoylphenyl)-1H-Indole-2-Carboxamide and bezafibrate did not significantly affect the gene expression levels which were increased with acute hyperlipidemia induced by Triton WR1339. In conclusion, gene expression profiling identified the possible mechanism in which Triton WR1339 induces its acute hyperlipidemic effect which was reversed by the use of N-(3-Benzoylphenyl)-1H-Indole-2-Carboxamide.

RESUMO

It is estimated that 2-3% of children in the US have hypertension (HTN) and 8% of children ages 4-17 carry the diagnosis of attention-deficit hyperactivity disorder (ADHD). The prevalence of HTN and cardiovascular (CV) risk factors in children with ADHD on CNS stimulant treatment (stimulants) compared to no treatment and compared to their healthy counterparts is not well described. Using National Health and Nutrition Survey data, we examined demographic, blood pressure (BP) and CV risk factors of 4,907 children aged 12-18 years with and without the diagnosis of ADHD, and further examined the CV risk in a subgroup of ADHD patients on stimulants. Three hundred eighty-three (10.7%) children were reported to have ADHD, of whom 111 (3.4%) were on stimulants. Children with ADHD on stimulants were significantly younger, male, and white compared to those with ADHD not on medication and those without ADHD. Body mass index (BMI), eGFR, cholesterol, the prevalence of albuminuria, and poverty were not significantly different between the three groups. One hundred sixty (2.7%) had BP in the hypertensive and 637 (12.4%) in the pre-hypertensive range. The prevalence of elevated BP (HTN and/or pre-HTN range) was not different between children with ADHD on stimulants compared to ADHD without medication and those without ADHD. Heart rate (HR) was significantly higher in the ADHD group on stimulants vs. the groups ADHD on no stimulants and without ADHD. When the relationship between stimulants and the risk of abnormal BP was examined, there was a significant interaction between having BP in the HTN range and sex. After adjusting for BMI, race, and age, females with ADHD on stimulants tended to be older and had significantly more BP in the hypertensive range. On the other hand, males were more likely to be of a white race and older, but not hypertensive. Children with ADHD on stimulants have significantly higher HR than children with ADHD on no stimulants and children without ADHD. On the other hand, the prevalence of abnormal BP classification is comparable between the three groups.

RESUMO

Five novel derivatives of N-(9,10-dihydro-9,10-dioxoanthracenyl)-1H-indole-2-carboxamide were synthesized and their lipid-lowering effects studied in hyperlipidemic rats. Fusion of the anthraquinone derivatives at high temperature with 5-indole-2-carbonyl chloride, followed by recrystallization from chloroform/methanol gave the desired compounds in excellent yields. Compounds 1 to 5 at a non-toxic dose (1 ml of 57 microM solutions) and bezafibrate as positive control were administered to rats that were hyperlipidemic due to treatment with Triton WR-1339. A decrease in the plasma levels of triglyceride (TG) and low-density lipoprotein-cholesterol (LDL-C) and an increase in the plasma level of high-density lipoprotein-cholesterol (HDL-C) were observed with compounds 1, 3, 4, and 5. Compounds 1, 4, and 5 significantly reduced total cholesterol (TC) levels as well. These compounds may provide agents for targeting dyslipidemia and cardiovascular disease.

RESUMO

A novel series of 5-fluoro-N-(9,10-dihydro-9,10-dioxoanthracen-8-yl)-1H-indole-2-carboxamides (3c-3g) were synthesized. The present study was undertaken to investigate the possible antihyperlipidemic effect of these novel compounds on hyperlipidemic rats. Hyperlipidemia was induced by a single intraperitoneal injection of Triton WR-1339 (300 mg/kg). The tested animals were divided into normal control (NCG), hyperlipidemic control (HCG), compounds 3c-, 3d-, 3e-, 3f-, 3g- and bezafibrate (BF)-treated groups. At a dose of 15 mg/kg, compounds 3c-3g and BF (100 mg/kg) significantly (p < 0.0001) reduced elevated plasma triglycerides levels after 12 and 24 h compared to the hyperlipidemic control group. However, only compounds 3e and 3g obviously showed a significant (p < 0.0001) reduction in plasma total cholesterol levels after 12 and 24 h. Moreover, high-density lipoprotein cholesterol levels were significantly increased in all treated groups. The current study demonstrates that 5-fluoro-N-(9,10-dihydro-9,10-dioxoanthracen-8-yl)-1H-indole-2-carboxamides (3c-3g) have a definite antihyperlipidemic potential and these beneficial activities may contribute to their cardioprotective and antiatherosclerotic role.

RESUMO

BACKGROUND: Glycemic goals (hemoglobin A1c < 7%) are often not achieved in patients with type 2 diabetes despite the availability of many effective treatments and the documented benefits of glycemic control in the reduction of long-term microvascular and macrovascular complications. Several studies have established the important positive effects of pharmacist-led management on achieving glycemic control and other clinical outcomes in patients with diabetes. Diabetes prevalence and mortality are increasing rapidly in Jordan. Nevertheless, clinical pharmacists in Jordan do not typically provide pharmaceutical care; instead, the principal responsibilities of pharmacists in Jordan are dispensing and marketing of medical products to physicians. OBJECTIVE: To assess the primary clinical outcome of glycemic control (A1c) and secondary outcomes, including blood pressure, lipid values, self-reported medication adherence, and self-care activities for patients with type 2 diabetes in an outpatient diabetes clinic randomly assigned to either usual care or a pharmacist-led pharmaceutical care intervention program. METHODS: Patients with type 2 diabetes attending an outpatient diabetes clinic of a large teaching hospital were recruited over a 4-month period from January through April 2011 and randomly assigned to intervention and usual care groups using the Minim software technique. The intervention group at baseline received face-to-face objective-directed education from a clinical pharmacist about type 2 diabetes, prescription medications, and necessary lifestyle changes, followed by 8 weekly telephone follow-up calls to discuss and review the prescribed treatment plan and to resolve any patient concerns. The primary outcome measure was glycemic control (A1c), and secondary measures included systolic and diastolic blood pressure, complete lipid profile (i.e., total cholesterol, low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], serum triglycerides), and self-reported medication adherence (4-item Morisky Scale) and self-care activities (Summary of Diabetes Self-Care Activities questionnaire). Data were collected at baseline and at 6 months follow-up. Changes from baseline to follow-up were calculated for biomarker values, and between-group differences in the change amounts were tested using the t test for independent samples. A P value of < 0.05 was considered statistically significant. RESULTS: A total of 77 of 85 patients (90.6%) randomly assigned to the intervention group and 79 of 86 patients (91.9%) assigned to usual care had baseline and 6-month follow-up values. Compared with baseline values, patients in the intervention group had a mean reduction of 0.8% in A1c versus a mean increase of 0.1% from baseline in the usual care group (P = 0.019). The intervention group compared with the usual care group had small but statistically significant improvements in the secondary measures of fasting blood glucose, systolic and diastolic blood pressure, total cholesterol, LDL-C, serum triglycerides, self-reported medication adherence, and self-care activities. Between-group differences in changes in the secondary measures of HDL-C and body mass index were not significant. CONCLUSIONS: Patients with type 2 diabetes who received pharmacist-led pharmaceutical care in an outpatient diabetes clinic experienced reduction in A1c at 6 months compared with essentially no change in the usual care group. Six of 8 secondary biomarkers were improved in the intervention group compared with usual care.

RESUMO

A new series of N-(benzoylphenyl) and N-(acetylphenyl)-1-benzofuran-2-carboxamides (3a-3d and 4a'-4c') were synthesized. Compounds (3a, 3b, and 4a'-4c') were tested in vivo using Triton-WR-1339-induced hyperlipidemic rats as an experimental model for their hypolipidemic activity. The tested animals were divided into eight groups: control, hyperlipidemic, 3a, 3b, 4a', 4b', 4c', and bezafibrate. At a dose of 15 mg/kg, the elevated plasma triglyceride (TG) levels were significantly reduced in compounds 3b (p <0.0001) and 4c' (p <0.05) after 12 and 24 h compared to the normal control group. Furthermore, high-density lipoprotein-cholesterol levels were remarkably increased in compounds 3b (p <0.001) and 4c' (p <0.05). Meanwhile, compound 4b' slightly reduced the TG levels after 12 and 24 h. The present study demonstrated new properties of the novel series of benzofuran-2-carboxamides 3b and 4c' as potent lipid-lowering agents. It is, therefore, reasonable to assume that compounds 3b and 4c' may have a promising potential in the treatment of hyperlipidemia and coronary heart diseases.

RESUMO

In the search for new potential antihyperlipidemic agents, the present study focuses on the synthesis of novel N-(benzoylphenyl)-5-substituted-1H-indole-2-carboxamides (compounds 8-12, 15, 16, 18) and investigating their antihyperlipidemic activity using Triton WR-1339-induced hyperlipidemic rats as an experimental model. Hyperlipidemia was developed by intraperitoneal injection of Triton WR-1339 (250 mg/kg body weight). The tested animals were divided into normal control (NCG), hyperlipidemic (HG), compound 8, 9, 15, 16, 18- and bezafibrate treated groups. At a dose of 15 mg/kg body weight, compounds 9, 16, 18 and bezafibrate (100 mg/kg) significantly (p < 0.0001) reduced elevated plasma triglycerides levels after 12 h compared to the hyperlipidemic control group. However, only the group treated with compounds 9, 16 and 18 showed an obviously significant (p < 0.001) reduction in plasma total cholesterol levels after 12 h compared to the hyperlipidemic control group. Moreover, high density lipoprotein-cholesterol levels were significantly (p < 0.0001) increased in all treated groups after 12 h compared to the hyperlipidemic control group, except for compounds 8 and 15 which revealed inactive. It is therefore reasonable to assume that compounds 9, 16 and 18 may have potential in the treatment of hyperlipidemia.

RESUMO

Benzothiophene carboxamide derivatives of aminobenzophenone, aminopyridine, aminobenzimidazole, and aniline derivatives (compounds 1-9) were synthesized and compounds 3, 6, 7, 8, and 9 tested in vivo for their hypolipidemic activity. Compounds 1-8 were prepared adopting the fusion process at 130-150 degrees C between benzothiophene-2-carbonyl chloride and aminobenzophenones, aminopyridine, and anilines, respectively, and were obtained in high yield, while compound 9 was obtained from the reaction of benzothiophene acyl chloride with aminobenzimidazole in DMF at 160 degrees C. At a dose of 15 mg/kg body weight compounds 6, 7, and 9 significantly reduced plasma triglyceride levels in Triton WR-1339-induced hyperlipidemic rats in comparison to control rats. Furthermore, they significantly increased high-density lipoprotein levels. It is therefore reasonable to assume that compounds 6, 7, and 9 may have a promising potential in the treatment of hyperlipidemia and atherosclerosis.

RESUMO

Direct interaction between 7-chloro-1-cyclopropyl-6-fluoro-8-nitro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid and primary α-amino acids (exemplified by glycine, alanine, and l-valine) in aqueous ethanolic NaHCO(3) at 70-80°C for 24-72 h produced the respective N-(4-oxoquinolin-7-yl)-α-amino acids (6a-c). The latter derivatives underwent reductive lactamization upon treatment with Na(2)S(2)O(4) in aqueous ethanol to afford moderate yields of the corresponding pyrido[2,3-f]quinoxaline-8-carboxylic acids (8a-c). Acetylation of 8a-c using acetyl chloride afforded N(4)-acetylated hexahydro-2,7-dioxopyrido[2,3-f]quinoxaline-8-carboxylic acids (9a-c). The structures, assigned to these new heterocyclic products, are supported by analytical and spectral data. The synthesized compounds (6a-c/9a-c) showed appreciable antibacterial activity as compared with ciprofloxacin.

RESUMO

The N-(benzoylphenyl)-1H-indole-2-carboxamide derivatives 1-6 were synthesized, and the lipid-lowering effects of two of these novel compounds were studied using hyperlipidemic rats as an experimental model. Treatment of ethyl-1H-indole-2-carboxylate with aminobenzophenones in the presence of sodium ethoxide and DMF, followed by purification using column chromatography, gave the target compounds in good yields. The tested animals were divided into control, hyperlipidemic, compounds 2-, 3- and bezafibrate-treated groups. At a dose of 15 mg/kg body weight, compounds 2, 3 and bezafibrate significantly reduced the elevated plasma triglyceride levels after 7 and 24 h. Furthermore, the high-density lipoprotein-cholesterol levels were remarkably increased in all treated groups after 7 and 24 h compared to the hyperlipidemic control group. However, only compounds 2- and 3-treated groups obviously showed a significant reduction in plasma total cholesterol levels after 24 h. It is therefore reasonable to assume that 2 and 3 may have a promising potential in the treatment of hyperlipidemia and coronary heart diseases.

RESUMO

Using Triton WR-1339-induced hyperlipidemic rats as an experimental model, we investigated whether compound 4 [N-(9,10-dihydro-9,10-dioxoanthracen-2-yl)benzofuran-2-carboxamide] and compound 5 [N-(4-benzoylphenyl)benzofuran-2-carboxamide], two novel anti-hyperlipidemic agents, have any effect on plasma triglyceride (TG), total cholesterol (TC), and high-density lipoprotein cholesterol levels (HDL-C) levels. The tested animals were divided into control (CG), hyperlipidemic (HG), and compounds 4, 5, and bezafibrate (BF) treated groups. At a dose of 15 mg/kg body weight, compounds 4, 5, and BF significantly reduced elevated plasma TG levels after 7 and 24 h. Furthermore, HDL-C levels were remarkably increased in all treated groups after 7 and 24 h compared to the hyperlipidemic control group. However, only compounds 4 and 5 treated groups clearly showed a significant reduction in plasma total cholesterol levels after 7 and 24 h. It is therefore reasonable to assume that compounds 4 and 5 may have promising potential in the treatment of hyperlipidemia and atherosclerosis.

RESUMO

The lipid-lowering activity of a series of novel N-(benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide derivatives has been studied in Triton WR-1339-induced hyperlipidemia in rats. The test animals were divided into four groups: control, hyperlipidemic, compound + 4% DMSO [C1: N-(2-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (1), C2: N-(3-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (2), C3: N-(4-benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide (3)]-treated and bezafibrate (BF)-treated. At a dose of 15 mg/Kg body weight, compounds 2, 3 and BF significantly reduced elevated plasma triglycerodes levels after 12 h. Moreover, high density lipoprotein-cholesterol levels were significantly increased in all treated groups after 12 h compared to the hyperlipidemic control group, except for C1 which was inactive. In sum, it may be stated that the results of the present study demonstrated new properties of some N-(benzoylphenyl)-5-fluoro-1H-indole-2-carboxamide derivatives as potent lipid lowering agents and these beneficial activities may contribute to their cardioprotective and antiatherosclerotic role.

RESUMO

The lipid-lowering effects of two novel antihyperlipidemic agents, BMI2C [N-(4-benzoylphenyl)-5-methoxy-1H-indole-2-carboxamide] and DDMI2C [N-(9,10-dihydro-9,10-dioxoanthracen-2-yl)-5-methoxy-1H-indole-2-carboxamide], were studied using hyperlipidemic rats as an experimental model; hyperlipidemia was developed by intraperitoneal injection of Triton WR-1339 (200 mg/kg body weight). At a dose of 15 mg/kg body weight, BMI2C and DDMI2C significantly reduced elevated plasma triglyceride levels after 7 and 24 h. Furthermore, BMI2C and DDMI2C significantly reduced elevated plasma total cholesterol levels after 24 h. Interestingly, high-density lipoprotein-cholesterol levels were significantly increased in all treated groups. These findings indicate that the two studied novel compounds have a promising potential in the treatment of hyperlipidemia and atherosclerosis.
