The pharmacokinetic behavior of enrofloxacin (EF) was investigated in geese after oral (p.o.) and intravenous (i.v.) administrations of a single dose of 20 mg/kg body weight. Plasma concentrations of EF and its active metabolite, ciprofloxacin, were determined by high performance liquid chromatography fluorescence method. Plasma concentrations versus time were analyzed by non-compartmental meth...

In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...

BACKGROUND Vinorelbine (VRL)-cisplatin (CDDP) is an active doublet for advanced non-small cell lung cancer. CDDP has a narrow therapeutic index and may produce a cumulative nephrotoxicity over the treatment period. This study was to assess the risks of drug-drug interaction (DDI) over 3 consecutive cycles of VRL-CDDP combined treatments. PATIENTS AND METHODS An open-label, nonrandomised, phas...

Characterization of the time course and magnitude of enzyme induction due to multiple inducers is important for interpretation of clinical data from drug-drug interaction studies. A population interaction model was developed to quantify efavirenz autoinduction and further induction with concurrent carbamazepine coadministration. Efavirenz concentration data in the absence and presence of carbam...

The purpose of this study was to use solid lipid nanoparticles (SLN) to improve the pharmacological activity of ofloxacin. Ofloxacin-loaded SLN were prepared using palmitic acid as lipid matrix and poly vinyl alcohol (PVA) as emulsifier by a hot homogenization and ultrasonication method. The physicochemical characteristics of SLN were investigated by optical microscope, scanning electron micros...

N-{4-Chloro-2-[(1-oxidopyridin-4-yl)carbonyl]phenyl}-4-(propan-2-yloxy)benzenesulfonamide (MLN3126) is an orally available chemokine C-C motif receptor 9 selective antagonist. In nonclinical pharmacokinetic studies of MLN3126, nonextractable radioactivity was observed in plasma after oral administration of 14C-labeled MLN3126 ([14C]MLN3126) to Sprague-Dawley (SD) rats. In this study, the nonext...

A novel clinical study design was used to evaluate the blockade of a selective short-acting μ-opioid agonist (remifentanil) in 24 opioid-experienced subjects. Samidorphan (3-carboxamido-4-hydroxynaltrexone) is a novel opioid modulator with μ-antagonist properties. Objective (pupil diameter) and subjective (visual analog scale) responses to repeated remifentanil and saline infusion challenges we...

To date there has not been any report on catan-ionic hybrid lipidic nano-carriers, let alone a report on applying them to deliver insoluble anti-tumor drugs. Catan-ionic hybrid lipidic nano-carriers containing curcumin (CUR-C-HLN) inherit the merits of catan-ionic systems, hybrid lipidic systems and nano-structured carriers (the second-generation substitute of solid lipidic nano-systems). Catan...
