The present study concerned with the development and characterization of metronidazole microcapsules prepared by thermal change method using different ratios (1:1, 1:2 and 1:4) of ethyl cellulose in order to select the best microcapsule formulation with a good encapsulation efficiency and drug release profile. The obtained microcapsules were discrete, spherical with free flowing properties and ...

attempts have been made to prepare nanoparticles based on poly(lactic-co-glycolic acid) (plga) and doxorubicin. biological evaluation and physio-chemical characterizations were performed to elucidate the effects of initial drug loading and polymer composition on nanoparticle properties and its antitumor activity. plga nanoparticles were formulated by sonication method. lactide/glycolide ratio a...

it has been observed that most of the chemical entities have high lipophilicity and poor aqueous solubility, which result in poor bioavailability. in order to improve the bioavailability, the release behavior of such drugs should be improved. although there are numerous techniques to handle solubility related issue, but they are expensive due to involvement of complicated equipments, advanced m...

the purpose of this study was to develop a new monolithic matrix tablet to completely deliver glipizide in a zero order manner over a sustained period. two approaches were examined using drug in a formulation that contain polymer like hydroxylpropyl methyl-cellulose k 100 (hpmck) and eudragit l 100. the granules were prepared by wet granulation method and thereby formulated as f-1, f-2. f-3 and...

Previous studies have reported the efficacy of baclofen in the treatment of Gastroesophageal Reflux Diseases (GERD). The objective of present study is to evaluate the effect of co-administration of omeprazole 20 mg/d plus sustained Release baclofen (SR baclofen) vs omeprazole 20 mg/d plus placebo on alleviation of symptoms in patients with a diagnosis of GERD. A prospective, double blind, place...

terbutaline sulfate exhibits extensive first pass metabolism and a short elimination half life which makes frequent oral administration of the drug inevitable. a novel buccoadhesive controlled delivery system of the drug can easily overcome the problem. a two-layered core tablet composed of a fast release layer made of mannitol, lactose, peg and the drug attached to a sustained release layer co...

angelica essential oil (ao), a major pharmacologically active component of angelica sinensis (oliv.) diels, possesses hemogenesis, analgesic activities and sedative effect. the application of ao in pharmaceutical systems had been limited because of its low oxidative stability. the ao-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using response...

In this study,formulation of sustained-releasingmatrix tablet of bupropion 150 mg, using hydroxypropylmethylcellu lose(HPMC) 4000cps was evaluatedwith the aim of reducing the frequency of daily dose. The level of HPMC4000 ,polyvinylpyrolidone(PVP) and magnesium stearate(Mg St)was varied based on a 2level 3 factor factorial experimental designusing the release rate of the drug from the matrices ...

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...
