Metronidazole is an antiprotozoal drug which is also effective against anaerobic bacteria. The availability of several brands of Metronidazole tablets in Libyan pharmacies today places health practitioners and a pharmacist in a problem of drug substitution in case of a particular brand is not available. The aim of the present study was the evaluation and comparison of pharmaceutical equivalence of five different Metronidazole coated tablets 500 mg, which are commercially available in the private pharmacies in Tripoli city, produced by various pharmaceutical companies with different trade names. The pharmaceutical quality of five brands of Metronidazole tablets was analyzed using official and unofficial quality control tests prescribed in different Pharmacopoeia including uniformity of weight, thickness, hardness, disintegration time, drug content as well as dissolution rate and assay. Acceptable external features as well as uniformity in diameter and thickness were revealed for all the tablets. The entire selected brands complied with the official specifications for uniformity of weight, hardness and disintegration, they released more than 75% of their drug content within 45 minutes. It can be concluded that all the brands could be regarded as bioequivalent and therefore can be interchanged in the clinical practice; this sort of study is good indicator for the evaluation of the idealness of commercial products and showed the importance of post marketing investigation for the drugs imported and distributed in Libya.

Hydroxyethylrutosides (Troxerutin) is a standardized mixture of semi-synthetic flavonoids obtained by substituting hydroxyethyl groups in the naturally occurring flavonol rutin. Because there are four dissociation hydroxyls in rutin, some fifteen kinds of hydroxyethylrutins can be theoretically synthesized. The good quality of the raw material of a drug and the finished product must include the related impurities in an analytical investigation, and this seemed particularly important to the quality control of Troxerutin. According to the literature, it is clear that, the chromatographic analysis of Troxerutin still problematic as its sample can be considered as a complex sample as it contains plenty of different components. In this study, new HPLC technology named fused- core column was used to separate the major components of Troxerutin bulk powder. Fused – Core silica stationary phases represent key technological advancement in the area of fast HPLC separations. These phases are made by fusing 0.5 μm porous silica. The reduced intra – particle flow path of the fused particles provides superior mass transfer kinetics and better performance at high mobile phase velocities, while the fused – core particles provide lower pressure than sub – 2 μm particles. arabic 13 English 77

Introduction: Smoking causes substantial preventable morbidity, mortality and financial burdens. It is the main risk factor for many diseases and a significant cause of death. Smoking prevalence is high internationally and in Malaysia, especially among males. Smoking cessation is essential to reduce tobacco-related morbidity and mortality. Aim: To evaluate knowledge, attitude towards and practice of smoking among pharmacy students in the International Islamic University Malaysia (IIUM). Materials and Methods: A cross-sectional study was conducted using a validated structured self-administered questionnaire among a sample of IIUM pharmacy students (n=251) from November 2012 to December 2012. Descriptive and inferential statistics were used to summarise data and to examine the relationship between variables. Results: A total of 251 IIUM pharmacy students have participated in the survey. The median age of the participants was 21-23 years; 23.9% of them were males and 76.1% were females. The percentage of current smokers and ex-smokers was 0.4%, 0.8%, respectively. About 43% of the respondents had a good knowledge (score >16), more than half of them had a positive attitude (score >17), and about 38.4% had a good practice (score >11). Conclusion: Smoking prevalence among pharmacy students in IIUM is very low. However, conducting training and educational programs to improve knowledge, attitudes and practice of pharmacy students is highly recommended to assist their contribution to smoking cessation interventions in the future. arabic 15 English 87
