The estimation of bioequivalency using metabolite data was investigated for immediate release formulations with drugs exhibiting linear pharmacokinetics and no first-pass effect. This was… (More)
Simulations were conducted to address the question of whether metabolite data are required for bioequivalence evaluation of immediate release formulations with drugs exhibiting linear… (More)
The pharmacokinetics of morphine and its derived metabolite, morphine 3-monoglucuronide, were studied in normal and bile-cannulated dogs. High doses (7.2-7.7 mg/kg iv) caused renal and biliary… (More)
The pharmacokinetics of atropine (dl-hyoscyamine) was studied in six normal volunteers following a single 1-mg intravenous dose of atropine. Atropine plasma levels were collected for 24 hours and… (More)
Prostaglandins are believed to influence hypothalamic-pituitary-adrenal (HPA) axis function, but their specific effects on ACTH and cortisol secretion in humans are unclear. Acetylsalicylic acid… (More)
Methylphenidate modified-release products produce early and late peak concentrations critical for treatment of morning and afternoon symptoms of attention deficit hyperactivity disorder (ADHD).… (More)
Develop and validate particular, concrete, and abstract yet plausible in silico mechanistic explanations for large intra- and interindividual variability observed for eleven bioequivalence study… (More)
We investigated the effects of dose and intrasubject variability (ISV) on bioequivalence (BE) of a parent drug with a single metabolite formed by nonlinear first-pass. A BE simulation was done using… (More)
