Population pharmacokinetics of omeprazole in a random Iranian population
Background: Omeprazole is metabolized predominantly by CYP2C19, a polymorphically expressed enzymes that show marked interindividual and interethnic variation. These variations cause a substantial differences that have been reported in the pharmacokinetics of omeprazole. The aim of the present study was to evaluate the pharmacokinetic parameters of omeprazole in a random Iranian population. Met...
متن کاملSynthesis and Characterization of Molecular Imprinting Polymer Microspheres of Piperine: Extraction of Piperine from Spiked Urine
Molecularly imprinted polymer (MIP) microspheres for Piperine were synthesized by precipitation polymerization with a noncovalent approach. In this research Piperine was used as a template, acrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker, and 2,2'-azobisisobutyronitrile (AIBN) as an initiator and acetonitrile as a solvent. The imprinted and nonimprinted po...
متن کاملGastroretentive Orlistat Microspheres: Formulation, Characterization, and In Vitro Evaluation
The present study involves the preparation and evaluation of floating microspheres of orlistat for improving drug bioavailability by prolongation of gastric residence time. The microspheres were prepared by a solvent diffusion–evaporation technique using inert polymers (Eudragit RL100, cellulose acetate, and ethyl cellulose). The effect of three formulation variables (i.e., drug/polymer ratio [...
متن کاملPharmacokinetics of intrarectal omeprazole in alpacas.
The purpose of this study was to evaluate the pharmacokinetics of omeprazole in three different vehicles when administered rectally to six alpacas. Alpacas were given single doses of omeprazole (4 mg/kg) in a double-blinded, randomized cross-over design with a 1 week washout period. Omeprazole formulations consisted of (1) Treatment A: omeprazole paste mixed in surgical lubricant (2) Treatment ...
متن کاملReconstituted powder for suspension of antitubercular drugs formulated as microspheres for pediatric use.
The aim of the present investigation was to develop a novel dosage form of rifampicin and isoniazid to minimize degradation of rifampicin in acidic medium, to modulate the release of rifampicin in the stomach and isoniazid in the intestine, and to provide pediatric compliance. Rifampicin slowly diffuses out through this hydrogel matrix, thereby sustaining its release (50.08%). The release of is...
