The effects of three selective oral inhibitors, fluvoxamine (FLU), ketoconazole (KET), and verapamil (VER), on the pharmacokinetics (PK) of florfenicol (FFC) were investigated in chickens. The chickens were administered orally with saline solution (SAL), FLU (60 mg/kg), KET (25 mg/kg), or VER (9 mg/kg) for 7 consecutive days. Florfenicol was given to the chickens at a single dose of 30 mg/kg or...

Objective: A randomized, open-label, balanced, two-treatment, two-period, two-sequence, single-dose, crossover bioequivalence study comparing Rizatriptan 10 mg Orally Disintegrating Strips (ODS, test) with that of established Oral Lyophilisate mg, Maxalt-MLT® (reference) was conducted in 24 healthy male volunteers under fasting conditions. single oral dose administrated to each volunteer. Metho...

This study was designed to investigate the effects of tangerine, orange, and grapefruit juice on the pharmacokinetic pattern of cyclosporine A in rats. Forty male Sprague-Dawley rats were divided into four groups to receive water, orange, tangerine, or grapefruit juices respectively. Water or juices (10 ml/kg) were given orally twice a day for 3 days. Three hours after the 5th dose, cyclosporin...

We consider the classical scheduling problem on parallel identical machines to minimize the makespan. There is a long history of studies on this problem, focusing on exact and approximation algorithms, and it is thus natural to consider whether these algorithms are optimal in terms of the running time. Under the exponential time hypothesis (ETH), we achieve the following results in this paper: ...

the aim of this study was to characterize the effect of typhoid fever on pharmacokinetic parameters of levofloxacin (lf) and compare the pharmacokinetic parameters of the said antibiotic in healthy human volunteers and patients with typhoid fever. total of 12 subjects were divided into two groups “a” (healthy volunteers) and “b” (typhoid patients). single oral dose of lf 500 mg was given and 5 ...

bioequivalence study is a scientific and practical method used to compare the quality of a generic drug with a reference product. this study aimed to examine the bioequivalence of two closantel formulations produced with different sources of raw material by a domestic pharmaceutical company. due to long half- life of closantel, the study carried out by a parallel method. thirty sheep were divid...

clomipramine is a tricyclic antidepressant. different methods for determination of clomipramine hydrochloride in plasma have been described. most of these procedures favor the use of acidic back-extraction in extraction procedure and hplc as the analytical technique. in this study, the clomipramine extraction procedure was modified and a direct injection to the column was performed to shorten t...

Most of these procedures favor the use of acidic back-extraction in extraction procedure and HPLC as the analytical technique. In this study, the clomipramine extraction procedure was modified and a direct injection to the column was performed to shorten t...

The bioavailability of two dipyridamol tablet formulations of (Dipyridamole from Tolidaru and Persantin from Boehringer) was compared in 14 healthy male volunteers who received a single dose of 25 mg of the test (T) and the reference (R) products in a randomized balanced 2-way crossover design. Plasma samples were obtained over a 16 h interval and dipyridamole concentrations determined by HPLC ...

PurposeCelecoxib-tramadol co-crystal (CTC) is a first-in-class of celecoxib and racemic tramadol. This Phase 1 bioavailability study compared single-dose pharmacokinetic (PK) parameters CTC with those the individual reference products from United States, immediate-release tramadol, taken alone simultaneously to determine their systemic exposure.MethodsThis was single-center, randomized, single-...
