The present study was performed to compare the bioavailability of two digoxin 0.25 mg tablet formulation in 30 volunteers of both sexes. The study was conducted open with randomized two period crossover design and a thre...

The development and validation of a simple and accurate method by HPLC-UV to quantify meloxicam (MLX) in human plasma and its application to comparative bioavailability study between MLX formulation and manipulated melox...

The study was performed to compare the bioavailability of two hydroxyzine hydrochloride 25 mg tablet formulation in 16 volunteers of both sexes. The study was conducted open with randomized two period crossover design ...

"Iron is an essential micronutrient for higher plants. Although abundant in most soils, Fe3+ is not available for plant uptake, because of its poor solubility. Ferrous sulfate is a fertilizer used for crops but, Fe2+ is...

"Chagas disease, caused by Trypanosoma cruzi, remains a major neglected disease with limited therapeutic options. Benznidazole (Bzn) is the first-line treatment, despite low aqueous solubility, poor bioavailability and s...

A predictive in vitro-invivo correlation (IVIVC) can empower in vitro dissolution as a surrogate for in vivo bioavailability / bioequivalence. IVIVCs can decrease regulatory burden by decreasing the number of biostudies ...

The purpose of the present study was to prepare glycyrrhizic acid-phospholipid complex (GL-PLC) as to improve the oral bioavailability of glycyrrhizic acid (GL), enhance the drug efficacy and reduce the side effects. The...

Aunque la gatifloxacina ha sido usada en la clínica por algunos años, no son frecuentes los estudios pre-clínicos de este antibió- tico. El objetivo de este trabajo fue determinar los parámetros farmacocinéticos en...

The aim of this work was to determine the pharmacokinetics of intravenous (iv) and intramuscular (im) ceftazidime administered to lactating (LTG; n = 6) and non-lactating (NLTG; n=6) healthy Creole goats in 2 trials (T1 ...

Chitosan microparticles (Cs-MPs) for the dissolution and oral bioavailability improvement of curcumin (Cur) were prepared with sodium tripolyphosphate (TPP) by ionotropic gelation method. Response surface methodology (RS...

Fluorine substituents have become a widespread and important drug component, their introduction facilitated by the development of safe and selective fluorinating agents. Organofluorine affects nearly all physical and ads...

Hydroquinone (HQ) is a drug reported to possess manifold biological activities. HQ is highly unstable into various topical vehicles, presenting low topical bioavailability and a relevant level of toxicity. The Pluronic®...

The solubility behaviour of drugs remains one of the most challenging aspects in formulation development. Solid dispersions (SD) and inclusion complexes (IC) are two of the most promising strategies to improve the oral...

The aim of this study was to investigate the impact of solid dispersions of polyethylene glycol 6000 (PEG 6000), using the co-precipitation method, on the in vitro solubility and intestinal absorption of praziquantel (PZ...

The study was conducted to evaluate the bioequivalence of deferiprone 500 mg with innovator drug in Pakistani men. Twenty four healthy volunteers were enrolled in this study. Each volunteer take two tablets of generic a...

Rhizoma Paridis saponins (RPS) were considered to be the principal bioactive components of Paris polyphylla Smith var. yunnanensis. Intestinal microflora-mediated metabolism may affect their pharmacological activities in...

The objective of this study was to compare the pharmacokinetic characteristics of ascaridole following oral administration of pure ascaridole and Jinghuaweikang (JHWK) capsule. Besides, additional rats were given pure as...

The present investigation concerns the development of floating tablets of tramadol hydrochloride, which after oral administration are designed to prolong the gastric residence time; improves the drug bioavailability, red...
