The aim of this study was to develop and validate a dissolution test for the quality control of deflazacort (DEF) tablets, a drug mainly used for the prevention of organ transplantation rejection, labeled as containing 6 mg of active pharmaceutical ingredient (API), using an RP-HPLC method. After testing sink conditions and stability at 37°C, DEF was found to be unstable, and decomposed as a fu...

Aceclofenac is an analgesic and anti-inflammatory agent used in the management of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. The objective of the present work was to investigate the effect of different types of carriers such as polyvinyl pyrrolidone (PVP), polyethylene glycol (PEG) 6000 and sodium lauryl sulphate (SLS) as solubilizer on in vitro dissolution of aceclofenac....

extended-release matrix tablets of diltiazem hydrochloride (dtz) were prepared using waxy materials alone or in combination with kollidon sr. matrix waxy materials were carnauba wax (cw), bees wax (bw), cetyl alcohol (ca) and glyceryl monostearate (gms). dissolution studies were carried out by using a six stations usp xxii type 1 apparatus. the in vitro drug release study was done in 1000 ml ph...

The aim of this research project was to investigate a potential standardized test method to characterize the dissolution properties of numerous formulation types available for pulmonary delivery. A commercially available dissolution tester was adapted for use as a testing apparatus by the incorporation of a membrane-containing holder. The holder was designed to enclose previously air-classified...

The present work deals with the comparison of in vitro dissolution profiles of fenofibrate liquisolid tablet formulations with those of marketed fenofibrate tablets, and the application of statistical methods to evaluate each method for its usefulness. The methods used to study dissolution profile comparison include Model independent method (Similarity factor, f2); Model dependent methods (Zero...

In the present study, Mefenamic acid 200 mg controlled release matrices were prepared by direct compression and in vitro drug dissolution studies were performed to find out the drug release rate and patterns. Methocel was used as rate controlling polymer. Also the effect of several co-excipients was investigated on the drug release rates during in vitro dissolution studies. Polymer Methocel was...

The present work was aimed to design and develop self-nanoemulsifying drug delivery systems (SNEDDS) with the objective to overcome the problems associated with the delivery of talinolol, a hydrophobic and poorly bioavailable drugs having pH dependant solubility. The solubility of talinolol in various oils, surfactants, cosurfactants and aqueous phases were determined to identify and select the...
