Buprenorphine is a partial mu agonist and kappa antagonist which is used for the treatment of pain and opioid addiction. A mixture of buprenorphine hydrochloride and naloxone hydrochloride has been approved for the treatment of opioid dependence.In this study a third order derivative spectrophotometric method based on zero-crossing technique has been used for the simultaneous determination of b...

In the United States, few intramammary antimicrobials exist that are approved for treatment of bovine mastitis; thus, ensuring judicious use of these products is a priority. The objectives of this study were to determine phenotypic susceptibility and presence of selected antimicrobial resistance genes from staphylococci, streptococci, and streptococcal-like organisms recovered from cases of cli...

The in vitro susceptibilities of 76 isolates of Actinobacillus pleuropneumoniae collected from pigs with pleuropneumonia were tested with 12 commonly used antimicrobial drugs by an agar dilution minimal inhibitory concentration procedure according to National Committee for Clinical Laboratory Standards (NCCLS) guidelines. Field isolates had low MICs for ceftiofur, danofloxacin and penicillin. N...

CTX-M-type beta-lactamases are increasing among US Enterobacteriaceae isolates. Of 2,165 non-Typhi Salmonella isolates submitted in 2007 to the National Antimicrobial Resistance Monitoring System, 100 (4.6%) displayed elevated MICs (≥2 mg/L) of ceftriaxone or ceftiofur. Three isolates (serotypes Typhimurium, Concord, and I 4,5,12:i:-) contained bla(CTX-M-5), bla(CTX-M-15), and bla(CTX-M-55/57),...

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...

REASONS FOR PERFORMING STUDY Systemic administration of ceftiofur crystalline free acid (CCFA) may be a potential treatment for infectious endometritis caused by Streptococcus equi ssp. zooepidemicus (S.  zooepidemicus) and other susceptible bacterial organisms in the mare. OBJECTIVE To determine if i.m. administration of CCFA at the label dose will exceed the minimum inhibitory concentration...

bla(CTX-M) beta-lactamases confer resistance to critically important cephalosporin drugs. Recovered from both hospital- and community-acquired infections, bla(CTX-M) was first reported in U.S. livestock in 2010. It has been hypothesized that veterinary use of cephalosporins in livestock populations may lead to the dissemination of beta-lactamase-encoding genes. Therefore, our objectives were to...
