combination dosage forms of naproxen sodium and pseudoephedrine hydrochloride are used for symptomatic treatment of cold and sinus disorders. in this study, fourth-order derivative spectrophotometric method was used for simultaneous determination of naproxen sodium and pseudoephedrine hydrochloride. the method was linear over the range of 2-28 μg/ml for pseudoephedrine hydrochloride and 4-200 μ...

two simple, accurate and precise methods for simultaneous estimation of esomeprazole and itopride in bulk drug and tablet dosage form have been described. method-a employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. method -b is absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.beer’s law was obeyed in the con...

OBJECTIVES To determine in vitro susceptibilities of a large series of speciated coagulase-negative staphylococci (CNS) against three new antibiotics, linezolid, quinupristin/dalfopristin and telithromycin. METHODS Susceptibilities to three new antibiotics and oxacillin, vancomycin, clindamycin and erythromycin were determined by the agar dilution method, as described by the NCCLS. RESULTS ...

Lincosamides are a class of antibiotics used both in clinical and veterinary practice for a wide range of pathogens. This group of drugs inhibits the activity of the bacterial ribosome by binding to the 23S RNA of the large ribosomal subunit and blocking protein synthesis. Currently, three X-ray structures of the ribosome in complex with clindamycin are available in the Protein Data Bank, which...

The treatment of experimental gas gangrene caused by Clostridium perfringens was investigated by using combinations of antimicrobial agents. This study demonstrated that rifampin, penicillin, metronidazole, and clindamycin were all bactericidal against standard inocula (10(5) to 10(6) CFU). These antimicrobial agents were then administered to mice beginning 30 min after intramuscular injection ...

Abstract In the present study, antibiotic resistance profiles and biofilm forming abilities of 9 Listeria monocytogenes isolates obtained from out 30 retail meat samples were determined, effect commercial white vinegar on these virulence factors in exposed to subMIC concentrations investigated. All found be resistant cefotixin oxacillin, 8 (26.6%) clindamycin, 1 isolate (3.3%) rifampicin, was s...

Clindamycin, a semi-synthetic antibiotic of the lincomycin family, at a dose of 450 mg eight-hourly for three days in adults cured five out of 10 patients moderately ill with chloroquine-resistant falciparum malaria. Combination therapy with full-dose quinine and clindamycin for three days cured all four patients so treated who were followed up, and with half dosage three out of five patients w...

Bacterial counts were carried out on the faeces of 160 patients receiving clindamycin or lincomycin treatment for bacterial infections. In all the patients the total bacteroides count was significantly reduced while strains of Enterobacteriaciae, yeasts, and streptococci were correspondingly increased. Severe diarrhoea developed in 25 (16%) patients, but this could not be related to a change in...
