Formulation and pharmacopoeial quality evaluation of ketorolac tromethamine IR tablet and comparison with marketed product

This study describes the formulation of immediate release Ketorolac tromethamine (KT) 10-mg tablet by directcompression method; evaluation of their compliance to various Pharmacopoeial quality parameters, i.e., weightvariation, friability, hardness, thickness, moisture content, disintegration, assay, and dissolution; and their comparisonwith marketed brands for determination of pharmaceutical equivalency. Five formulations of KT were prepared(coded as FKT1, FKT2, FKT3, FKT4, and FKT5) by direct compression method using different superdisintegrants.Micrometric properties of the mixtures of the drug and the excipients prepared for formulation were evaluated. Qualityevaluation of the five different formulations and randomly selected four different brands of KT 10-mg tablets purchasedfrom the local market (coded as LKT1, MKT2, MKT3, and SKT4) were performed according to Pharmacopoeia. Theresults were obtained by UV-Vis spectrophotometer and all the dissolution profiles were characterized by the zeroorder kinetics. All the brands of KT and developed formulations met the official specification except SKT4 whichshowed excessive moisture content of 7.18%. None of the tested brands of KT were found to be pharmaceuticallyequivalent, whereas two developed formulation were pharmaceutically equivalent with the in house benchmark(MKT2) from which their interchangeability can be suggested.

Current status of gonococcal antimicrobial susceptibility with special reference to azithromycin and ceftriaxone: report from a tertiary care hospital in bangladesh

Objectives: Successful treatment of gonorrhea has always been jeopardized by the emergence of resistance to antibiotics recommended as first-line therapies. The present investigation was carried out to demonstrate the current status of antimicrobial susceptibility of N. gonorrhoeae with a special reference to azithromycin and ceftriaxone

Methods: Microscopical detection in Gram-stained smear and isolation by culture in Thayer-Martin medium were done for 60 clinically suspected gonorrhea patients using urethral discharge or prostatic secretion for male and endocervical secretion for female. Isolates of N. gonorrhoeae were subjected to antimicrobial susceptibility testing by modified Kirby Bauer disk diffusion method against eight antimicrobial drugs including azithromycin and ceftriaxone

Results: Culture yielded a total of 25[42%] isolates of N. gonorrhoeae from 60 clinically suspected patients of both sexes; 21 from male [17 from urethral discharge and 04 from prostatic secretion] and 04 from female [endocervical secretion]. Isolates of N. gonorrhoeae showed moderate to high resistance [60 to 88%] to penicillin, tetracycline, cotrimoxazole, erythromycin, ciprofloxacin and cefixime. While resistance to azithromycin and ceftriaxone was 60% and 48% respectively, which was also moderate

Conclusion: Our findings indicate moderate to the high resistance of N. gonorrhoeae to conventional antibiotics. It also showed moderate resistance to azithromycin and ceftriaxone, current dual therapy recommended by the WHO for the treatment of genital gonorrhea, which is alarming

Synthesis of barbituric acid derivatives using microwave irradiation method and in vitro evaluation of antimicrobial and cytotoxic activity.

The research work was involved in rapid and efficient procedure for the attachment of barbituric acid with arylidene acetophenone under microwave irradiation (MWI) and conventional heating. The result showed that the time was reduced from the conventional 24 hours to 5-10 minutes. In conventional heating, the yield of the compounds 2a-2e were very poor (75-81%), but in MW methods the yields were observed 96.48-98% which was comparatively too high. The structures of the compounds were characterized by FT-IR, 1H-NMR spectral data. The antimicrobial and cytotoxic activities of the synthesized compounds were also investigated. Staphylococcus aureus, Bacillus megaterium, Escherichia coli and Pseudomonas aeruginosa revealed the zone of inhibition were 6-12 mm where sample concentration was 100 μg/disc. However, cytotoxic analysis, the mortality 47-95% were appeared when sample concentration were 0.78-25 (μg/ml) and more than 50 (μg/ml) concentration showed 100% mortality. The presence of a reactive and unsaturated ketone function in synthesized compounds was found to be responsible for their potential antimicrobial and cytotoxic activity.

Non - operative management of perforated peptic ulcer

The aim of this study was to see the morbidity and mortality in peptic ulcer perforation cases by non-operative management in selected cases. Design: The cases were selected on the basis of structured protocol. Setting: This study was carried out in the Department of Surgery of Khulna Medical College Hospital located in southern Bangladesh over a period of 10 years. Subjects: The patients were diagnosed as perforated peptic ulcer clinically and radiologically. All patients in this series had pneumoperitoneum in plain x-ray abdomen. They included 54 patients of peptic ulcer perforation cases had the following parameters: early presentation [<12 hours], soft abdomen with minimum tenderness and relatively younger patients. All patients were chosen who were haemodynamically stable. Ultrasonography was done in doubtful cases and also to see the amount of free fluid inside the abdominal cavity. Methodology: After diagnosis, all patients were managed in a similar fashion-like nil by mouth, continuous gastric aspiration, application of intravenous fluids and antibiotics and antiulcer therapy. In the selected 54 patients, male: female were 49:05. Nine had history of NSAID intake. There was no mortality. Morbidity analysis showed that three had hepatic abscess, four had pelvic abscess, six took prolonged time for improvement, in two cases conservative treatment had to be abandoned and laparotomy was done in the same hospital admission. Non-operative procedure is a safe and effective measure for the management of perforated peptic ulcer in selected cases
