Influence of midazolam on pharmacokinetics of verapamil in rabbits.
Calcium channel blockers can get involved in pharmacological interactions when used concomitantly with other drugs. Previous reports indicate a differential influence of various general anesthetics on verapamil pharmacokinetics. A tendency of a faster transfer of verapamil from the central compartment to the tissue compartment was found to be associated with a slower drug return from the tissue...
متن کاملDrug-Drug Interactions: Influence of verapamil on the pharmacokinetics of sitagliptin in rats and Ex vivo models
P-glycoprotein (P-gp) and cytochrome P450 3A4 (CYP3A4) play a significant role in the disposition and elimination of drugs. The objective of this study was to investigate the mechanism underlying the interaction between sitagliptin (substrate of P-gp and CYP3A4) and verapamil (known modulator of P-gp and CYP3A4) using in vivo, ex vivo and in situ models. Rats were treated with sitagliptin (10 m...
متن کاملCorrection to: "PBPK Modeling to Unravel Nonlinear Pharmacokinetics of Verapamil to Estimate the Fractional Clearance for Verapamil N-Demethylation in the Recirculating Rat Liver Preparation".
We applied physiologically based pharmacokinetic (PBPK) modeling to study the dose-dependent metabolism and excretion of verapamil and its preformed metabolite, norverapamil, to unravel the kinetics of norverapamil formation via N-demethylation. Various initial verapamil (1, 50, and 100 μM) and preformed norverapamil (1.5 and 5 μM) concentrations, perfused at 12 ml/min, were investigated in the...
متن کاملStercoral perforation with verapamil.
Sir, Constipation is the commonest and most troublesome non-cardiac side effect of verapamil use.', We would like to report a case of stercoral perforation in a woman taking verapamil. A 78 year old woman was admitted with sudden onset of lower abdominal pain associated with signs of generalized peritonitis. She had developed chronic constipation after commencement of verapamil for recurrent su...
متن کاملThe Influence of Verapamil
The -effect of verapamil on the pharmacokinetics of digoxin was studied in 49 patients with chronic atrial fibrillation. A dose of 240 mg/day of verapamil was given to the patients who were receiving a stable dose of digoxin. Serum digoxin levels rose from 0.76 i 0.54 ng/ml (mean ± SD) to 1.31 ± 0.54 ng/ml during verapamil treatment (p < 0.0005). This effect was dose-dependent, as shown in seve...
