Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive tract. Acquired functional mutations in the tyrosine-protein kinase growth factor receptor proto-oncogene (KIT) and platelet-derived growth factor-alpha gene lead to increased tyrosine kinase activity, which is considered a key factor in the pathogenesis of GIST.

Due to the increasing number of therapeutic monoclonal antibodies (mAbs) used in the clinic, there is an increasing need for robust analytical methods to quantify total mAb concentrations in human plasma for clinical studies and therapeutic drug monitoring. We developed an easy, rapid, and robust sample preparation method for liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis.

In the present experiment the depletion profile study of Albendazole and its metabolites (ABZSO and ABZSO2) were carried out in the plasma of Pangasianodon hypophthalmus. The experiment consists of three treatment groups and control. A 20mg/kg body weight dose of ABZ was given through intraperitoneal, intramuscular and orally respectively to the three treatment groups while no drug was given to control group.

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

Present study was conducted for pharmacokinetic interaction of long acting moxofloxacin (LA moxifloxacin) with meloxicam at the dose rate of 7.5 mg.kg-1 and 0.5 mg.kg-1 respectively following intramuscular (IM) administration. Peak plasma concentrations of drug were estimated by using HPLC florescence detector

The physiologically based pharmacokinetic (PBPK) model for liver transporter substrates has been established previously and used for predicting drug–drug interactions (DDI) and for clinical practice guidance. So far, nearly all the published PBPK models for liver transporter substrates have one or more hepatic clearance processes (i.e., active uptake, passive diffusion, metabolism, and biliary excretion) estimated by fitting observed systemic data.

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.
