The study evaluated different quality control parameters of five brands of Cefuroxime 250mg tablets which are already marketed in Bangladesh. Five brands of the drug sourced from different retail outlets to assess the quality assessment and comparison of the tablets using the in-vitro release study. The brands were subjected to various official tests including uniformity of weight, thickness test, dissolution tests, and cumulative % of drug release and friability test. This research further focuses on the requirement of manufacturers to construct quality into their products during manufacture and also sustain the built-in quality from batch to batch in line with the principles of cGMP.

Objective: The present study was performed to compare the quality of conventional tablets loaded with candesartan cilexetil. The selected candesartan cilexetil tablets were commercialized in the Iraq market and produced by different companies. Methods: Different batches of candesartan cilexetil oral tablets (the concentration of candesartan was 8 mg) were subjected to quality control tests. Tests included weight variation, friability, hardness, drug content, disintegration time and in vitro release study. The protocols of these tests were performed according to USP pharmacopeia. Results: The results, in this study, revealed that all the used batches of candesartan cilexetil oral tablets complied with the specification of USP pharmacopeia for weight uniformity, friability value (% loss) was<1. Hardness results of the tablets were 4.9-6.6 Kg/cm2, which was within the required limits (i.e. 4-8 Kg/cm2). Disintegration time was<15 min in both Simulated Gastric Fluid (SGF) and Simulated Intestinal Fluid (SIF). The percentage of drug content in all marketed tablets was found between 96.2 % and 99.8 %, reflecting compliance with the pharmacopeia limits (i.e. 85-115 %). An in vitro release study indicated that the release of all marketed tablets exceeds 80 % within 15 min. Conclusion: All the studied tablets, loaded with candesartan cilexetil, were produced within the standard criteria of tablet production. The quality control analysis of the selected tablets, in this study, revealed satisfactory pharmaceutical properties (including safety and effectiveness) that comply within the limits of USP pharmacopeia.

Objective: This study was employed to evaluate the quality of marketed oral tablets containing clopidogrel bisulfate. Tablets produced by various companies and commercialized in the Iraq market were used in the study. Methods: Batches of clopidogrel bisulfate conventional tablets (containing 75 mg of drug) were exposed to the quality control tests. These tests involved friability, weight variation, hardness, drug content, disintegration time, and in vitro release study; these tests were conducted depending on USP pharmacopeia. Results: The data indicate that all batches of clopidogrel bisulfate complied with the limitations of USP pharmacopeia for variation of weight, results of the hardness of tablets were 7.2-9.6 Kg/cm2. Friability value (% loss) was less than one, which was within the required limits. The time of disintegration was less than 25 min in both artificial gastric fluid (AGF) and artificial intestinal fluid (AIF). Drug content was observed between 97.1 % and 99.8 %, indicating compliance with the limits of pharmacopeia (85-115 %). An in vitro release study of batches was greater than 80 % within 25 min. Conclusion: All batches of clopidogrel bisulfate were manufactured within the criteria of tablet manufacturing. The quality control tests of tablets showed acceptable pharmaceutical properties (effectiveness and safety) that lie within the limits of USP pharmacopeia.

This study seeks to formulate and evaluate a solid lipid nanoparticle-based, solidified micellar carrier system for oral delivery of cefepime. Cefepime has enjoyed a lot of therapeutic usage in the treatment of susceptible bacterial infections; however, its use is limited due to its administration as an injection only with poor patient compliance. Since oral drug administration encourage high patient compliance with resultant effect in improved therapy, cefepime was formulated as solid lipid microparticles for oral delivery using the concept of solidified micellar carrier system. The carrier system was evaluated based on particle yield, particle size and morphology, encapsulation efficiency (EE %), and thermal analysis using differential scanning calorimeter (DSC). Preliminary microbiological studies were done using gram positive and negative bacteria. In vitro release study was performed using biorelevant media, while in vivo release study was performed in white albino rats. The yield of solid lipid microparticles (SLM) ranged from 84.2 – 98.0 %. The SLM were spherical with size ranges of 3.8 ± 1.2 to 42.0 ± 1.4 µm. The EE % calculated ranged from 83.6 – 94.8 %. Thermal analysis showed that SLM was less crystalline with high potential for drug entrapment. Microbial studies showed that cefepime retained its broad spectrum anti-bacterial activity. In vitro release showed sustained release of cefepime from SLM, and in vivo release study showed high concentration of cefepime released in the plasma of study rats. The study showed that smart engineering of solidified micellar carrier system could be used to improve oral delivery of cefepime.

The goal of this study was to formulate and evaluate norfloxacin sustained release tablets. Norfloxacin sustained release tablets were prepared by wet granulation method using two polymers such as HPMC K 100 M (hydrophilic polymer) and guar gum (natural polymer) and with three polymer ratios (0.5, 1.0 and 1.5). The prepared granules were evaluated to preformulation studies such as angle of repose, bulk density, tapped density, bulkiness, compressibility index and Hauser’s ratio. All the parameters shows that the granules having good flow properties. Then the formulated tablets were taken to evaluation studies such as hardness, weight variation, friability, drug content and thickness. All the parameters were within the acceptable limits. IR spectral analysis showed that there was no interaction between the drug and polymers. The in vitro release study was performed in phosphate buffer pH 7.4 at 293 nm. The in vitro release study showed that if the polymer ratio is increased, then the release of the drug is prolonged. HPMC K 100M shows a prolonged release when compared to guar gum.
