Purpose: To prepare and evaluate spherical agglomerates of pioglitazone hydrochloride (PGH) for direct compression with different additives. Method: Spherical agglomerates of pioglitazone hydrochloride were prepared by emulsion solvent diffusion method with and without additives (polyethylene glycol 6000, polyvinyl pyrrolidone, β cyclodextrin, Eudragit RS100, low acyl gellan gum and xanthan gum...

felodipine is a second generation calcium channel blocker widely used as antihypertensive and antianginal drug which belongs to bcs class ii category. hence, its low water solubility limits the pharmacological effect. the aim of this study was to improve the dissolution rate of felodipine using spherical agglomeration technique with acetone, water and dichloromethane as good solvent, poor solve...

Background: Intravenous drug delivery is an advantageous choice for rapid administration, immediate drug effect, and avoidance of first-pass metabolism in oral drug delivery. In this study, the synthesis, formulation, and characterization of atorvastatin-loaded polyurethane (PU) nanoparticles were investigated for intravenous route of administration. Method: First, PU was synthesized and charac...

Biodegradable poly(D, L-lactide-co-glycolide) (PLGA) and PLGA-based polymeric nanoparticles are widely used for sustained release of protein and peptide drugs. These formulations are usually prepared by water/oil/water (W/O/W) and solid/oil/water (S/O/W) double emulsion solvent evaporation method. Other methods of preparation are nanoprecipitation, emulsion solvent diffusion and salting-out. Th...

The aim of this study was to prepare and evaluate microspheres containing ibuprofen. Microspheres were prepared by modified quasi-emulsion solvent diffusion method. The influence of formulation factors (drug-polymer ratio, volumes of solvent, polyvinyl alcohol concentration and type of polymer) on the morphology, particle size distribution, drug loading capacity, micromeritical properties and t...

Microspheres are multiparticulate drug delivery systems which are prepared to obtain prolonged or controlled drug delivery to improve bioavailability, stability and to target the drug to specific site at a predetermined rate. They are made from polymeric waxy or other protective materials such as natural, semi synthetic and synthetic polymers. Microspheres are characteristically free flowing po...

The success in the preparation of Eudragit RS100 microspheres in 0.IN HCI solution using gelatin as antiaggregating agent, encouraged the selection of an acidic drug to be encapsulated using a solvent evaporation technique [1]. Ibuprofen is a non-steroidal, anti-inflammatory, analgesic and antipyretic drug approved for use as adjunct therapy in the treatment of rheumatoid and osteoarthritis [2]...

In this work, we are motivated by the need to produce particles of well-controlled size, shape and morphology for general application in catalysis, environmental remediation, nanomedicine, pharmaceuticals, the development of new materials, and other fields. Moreover, our approaches are guided by the desire for continuous and scalable production, in contrast to the batch-wise processes typically...

Abstract: Aim/Background: The purpose of the study was to fabricate and evaluate atenolol loaded micro-sponge in-situ gel. Materials Methods: Oil in Emulsion Solvent Diffusion Technique used for formulation microsponges by using different levels polymers such as Eudragit RS-100 Ethyl Cellulose. prepared micro-sponges were evaluated optical microscopy, percentage yield, drug content, entrapment ...
