The antibiotic consumption ratio in this province was comparable to neighbouring countries, but far higher compared to European countries. Penicillins, cephalosporins and quinolones were the most popular antibiotics. Around half of the antibiotics consumed were made by national pharmaceutical companies that mainly produce oral antibiotics. The public sector consumed a higher portion, but spent a lower amount compared to private sectors. This is the first time report of antibiotic consumption in Iraq. More studies evaluating antibiotic consumption can improve utilization.
Acne vulgaris usually associated with bacterial infections which develops antibiotic resistance in short time. To overcome the resistance, high dose of antibiotic must be directed toward the infected site for appropriate treatment period. For this reason, ciprofloxacin HCl in liposomes may have a chance to concentrate at hair follicles and sebaceous gland and treat skin infections and acne. Aim of this study was to find out the best formula in terms of entrapment efficiency and elasticity among the prepared formula in addition to find the effect of method of preparation on prepared liposomes. Multiple formulas were prepared using 100 mg of ciprofloxacin HCl, 700 mg of phospahtidylcholine with different concentrations of cholesterol (10, 20, 30 and 40 mg). Formulas contain 20 and 30 mg of cholesterol were selected to study the effect of sodium deoxycholate. Rotary evaporator and bath sonication methods were utilized to prepare liposomes. Liposomes properties as entrapment efficiency, vesicles size, relative deformability (elasticity) and pH were studied. Regarding formulas prepared by rotary evaporator, formula which contains 30 mg cholesterol and 25 mg sodium deoxycholate has higher entrapment efficiency (77.24 %). While the highest entrapment efficiency (81.99 %) was obtained from formula contain 20 mg cholesterol alone prepared by sonication method. Liposomes are relatively small in size and ranged between 8.89 -89.9 microns. Sonication method gives liposomes with higher elasticity (relative deformability equal to 7 minutes) for both formulas prepared by 20 mg cholesterol and 50 and 75 mg sodium deoxycholate respectively. No significant effect for method of preparation on pH of the formulas were observed as the pH values ranged between 4.4 -5.5.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
