Multielement analysis of crude drug and infusions from Achyrocline satureioides and A. tomentosa (Asteraceae), "marcelas", were carried out by ICP-OES, to know both mineral composition and safety. These plants are used a...

A new reversible thermosensitive drug delivery system was designed and prepared by using chitosan and glycerophosphate with or without poly (ethylene glycol) and used as an a carrier for the Miconazole nitrate, an antifu...

The aim of the present investigation is to improve the dissolution of poorly water soluble drug valsartan by preparing solid dispersions and also to evaluate the effect of different inert carriers on flow properties of s...

The objective of the present study was to develop and evaluate a pulsatile system of theophylline based on chronopharmaceutical considerations. The basic design consists of an impermeable capsule body, which contains the...

The present study was undertaken to investigate the effect of nature of polymers like HPMC, carbopol-934P and their content levels on the release profiles of water soluble drug, diclofenac potassium. For this purpose, di...

Lipid-based nanocarriers were prepared by hot solvent diffusion technique. Tristearin (TS) and/or castor oil were employed as oily phase, and Lutrol F68® or Solutol HS15® and lecithin were employed as surfactant and co...

Novel stable mucoadhesive chitosan microspheres were developed to explore the possibility of nasal delivery of L-dopa to avoid first pass metabolism and to improve therapeutic efficiency in treating the symptoms of parki...

Son diversas las etapas que deben cumplimentarse en Cuba para la introducción de un nuevo medicamento en el mercado, dentro de las que se encuentran la evaluación de parámetros físico-químicos, farmacológicos, to...

No presente estudo, os teores de heterosídeos de flavonóides, de lactonas terpênicas e de ácidos ginkgólicos foram determinados por CLAE, e também os perfis de dissolução de seis medicamentos fitoterápicos à ...

Achyrocline satureoides (Lam.) DC., Compositae (n.v. "marcela"), es una de las plantas medicinales más utilizadas con fines terapéuticos en la elaboración de fitofármacos en nuestra región. Sus principales actividad...

El objetivo del trabajo consiste en construir un cuestionario capaz de determinar y comparar el nivel de satisfacción de los pacientes de distintos subsectores del sistema de salud en la utilización de medicamentos p...

Este trabalho objetivou caracterizar e avaliar a qualidade de matérias-primas (MPs) de primaquina de diferentes fornecedores, designadas amostras A, B, C e D. Os resultados de características físicas, solubilidade, fa...

Effervescent tablets have always been convenient, simple and measured dosage form. The phenomenon of carbonation, in this type of dosage form, accelerates the solubility and enhances the bioavailability of the drug and t...

The purpose of this paper was to produce controlled-release matrices with 120 mg of propranolol hydrochloride (PHCl) employing hydroxypropyl methylcellulose (HPMC, Methocel® K100) as the gel forming barrier. Although th...

Nanocapsule suspensions containing coenzyme Q10 were prepared by interfacial deposition. The nanocapsules showed characteristics compatible with dermal application: slightly acid pH, drug content close to 100%, particle ...

El objetivo del presente trabajo ha sido el de evaluar el efecto del peso molecular de acetobutirato de celulosa (ABC) (PM 30000 y 70000) y la presencia de polietilenglicol 1500 (PEG 1500) en el tamaño de microesferas p...

The transport of buspirone across rat intestine (duodenum, jejunum, ileum and colon) was studied by using the non-everted sac method. Rats were pretreated with ashwagandha (Withania somnifera) and Aloe vera juice for 7 d...

O objetivo deste estudo foi avaliar a estabilidade física e química de comprimidos gastro-resistentes contendo 20 mg de omeprazol. Os comprimidos sem revestimento (SR) e revestidos (R1 e R2) foram expostos nas seguin...

Hydrophilic matrix tablets were developed with acyclovir (ACV), using hypromelose and polyethylene oxide (PEO) in different concentrations. Matrix tablets obtained in each formulation were evaluated to determine the weig...

The dissolution behavior of five commercially available brands of sustained release theophylline tablets was studied in phosphate buffer solutions of pH 1.2, 4.5, 5.5, 6.0 and 7.5 at 37 °C using the USP dissolution ap...

Nimesulide was formulated as sustained release microcapsules using biodegradable polymer Poly(D,L-lactide-co-glycolide) (PLGA) as the release material by non-solvent addition coacervation method. The prepared microcaps...

This study introduced a novel phase separation technique for the microencapsulation of metoprolol tartrate as a model. Non-solvent addition coacervation technique was employed for the loading of drug into ethylcellulose,...

Microspheres were prepared using the emulsion/solvent evaporation method with the aim of obtaining diclofenac sodium (DFS) prolonged release dosage forms. The effects of the drug:polymer ratio and addition of Pluronic F6...

The aim of the study was to formulate and evaluate controlled release microspheres. Ciprofloxacin HCl, belonging to the class of fluroquinolones, was chosen as the model drug. The drugloaded microspheres were prepared wi...
