Objective(s) The purpose of the present study was to use the solid dispersion (SD) technique to improve the dissolution rates of indomethacin (IMC). Materials and Methods IMC solid dispersions in PVP K30 and isomalt (GALEN IQ 990) were prepared using the solvent evaporation technique and a hot melt method in weight ratios of 2, 10 and 30% (IMC:PVP). Solid dispersions and physical mixtures we...

Purpose: To formulate matrix type sustained-release (SR) tablets of tizanidine hydrochloride (TH) for prolonged drug release and improvement in motor activity after spinal injuries. Methods: Matrix tablets were prepared by the wet granulation method using four polymers (hydroxyl propyl methyl cellulose [HPMC] K 100, ethyl cellulose [EC], guar gum, and polyvinylpyrrolidone (PVP K30) and characte...

Repaglinide has the half life of 1 hour, and bioavailability in the body is 56% due to first-pass metabolism. The total daily dose of Repaglinide is 16 mg (e.g., 4 mg four times daily depending on meal patterns); hence, it required frequent dosing. Transdermal patch of Repaglinide was prepared to sustain the release and improve bioavailability of drug and patient compliance. Different formulati...

The goal of this investigation was to determine the effectiveness hydrophilic polymers in preparing a solid dispersion enhance solubility and dissolution poorly water-soluble drugs, such as curcumin. In order prepare dispersion, curcumin uniformly distributed polymeric matrix polyethylene glycol (PEG 6000), hydroxypropyl methyl cellulose (HPMC E5), polyvinyl pyrrolidine (PVP K30), bovine serum ...

objective(s): this study was performed aiming to investigate the effect of particle engineering via spray drying of hydroalcoholic solution on solid states and physico-mechanical properties of acetaminophen.   materials and methods: spray drying of hydroalcoholic solution (25% v/v ethanol/water) of acetaminophen (5% w/v) in the presence of small amounts of polyninylpyrrolidone k30 (pvp) (0, 1.2...

Cinnamon bark (Cinnamomum burmannii) is used traditionally and has an ingredient containing cinnamic acid compounds. Colocasia esculenta (L) Schott leaves contains of flavonoids, alkaloids, tannins, saponins, steroids, terpenoids. Both the plants C. burmannii have potential as anti-diabetics because they can lower blood glucose levels. This study aims to make combination tablets extract with va...
