Plasma disposition

Topical ophthalmic atropine sulfate is an important part of the treatment protocol in equine uveitis. Frequent administration of topical atropine may cause decreased intestinal motility and colic in horses due to systemic exposure.

Varying the rate of continuous intravenous infusions of 5-fluorouracil (5FU) chemotherapy over a 24-hour period has been reported to improve patient outcomes. It has been hypothesized that circadian variation in drug disposition is a contributing factor. We analyzed 5-FU concentrations during a 24-hour continuous 5-FU infusion

Bio-enhancers such as piperine, curcumine, ginger and cow urine distillate are being seen as important adjuvant drugs to combat antimicrobial resistance and to increase efficiency of antimicrobial agents. Cow urine distillate is one of the important bio-enhancer easily available with farmer. The disposition kinetics was aimed to assess the pharmacokinetic alteration in profile of moxifloxacin, a third generation fluoroquinolone anti-microbial agent. Moxifloxacin was administered at the dose rate of 5 mg.

Marbofloxacin is a third generation quinolone developed exclusively for veterinary use. The disposition kinetic profile of marbofloxacin was generated after a single intravenous bolus injection in male Sahiwal calves (n = 5) at the dose level of 2 mg.kg-1 body weight. Marbofloxacin concentrations in plasma were determined by microbiological assay using Escherichia coli MTCC 443 as the test organism. The plasma concentration–time profile following intravenous administration was best described by a two-compartment open model. The plasma drug concentration ≥ 0.12 μg.ml-1 was detected at 24 h.

Cefquinome is fourth generation cephalosporin developed exclusively for veterinary use. The present research was aimed to investigate the disposition kinetic profile of cefquinome at the dose level of 2 mg.kg-1 body weight following single intramuscular administration. Cefquinome concentrations in plasma were determined by microbiological assay technique using Kocuria rhizophila MTCC 1541 as the test organism. The plasma concentration– time profile following intramuscular administration was best described by onecompartment open model. The peak plasma concentration (Cmax) of 5.79 ± 0.35 μg.

The liquid chromatography–tandem mass spectrometric assay method for the simultaneous determination of rosuvastatin and amlodipine in human plasma using deuterated analogs as internal standards has been developed and validated. The analytes were extracted from 100 lL aliquots of human plasma via liquid–liquid extraction using a mixture of ethyl acetate and n-hexane (80:20, v/v) as an extraction solvent. The optimized mobile phase was composed of 0.1% formic acid in 5 mM ammonium acetate, methanol, and acetonitrile (20:20:60, v/v/v) and delivered at a flow rate of 0.75 mL/min.
