Different formulations of Indapamide 1.5mg sustained release tablets were formulated using wet granulation method using hydrophilic polymer. The tablets were subjected to physicochemical studies, in vitro release studies, kinetic modeling and stability studies to find out the best formulation. The in vitro release studies were conducted for 16 hours using USP 30 apparatus type I (Basket method)...

the short half-life of terbutaline sulphate (tbs) requires frequent dosing for controlling chronic pulmanary disorders, such as night asthma. the purpose of the present study was to prepare sustained-release (sr) tablets of tbs to decrease the number of doses frequency and to promote the paitent compliances. it was also desirable to evaluate the capability of natural gums for preparation of sr ...

   Oral pH sensitive drug delivery systems are of utmost importance as these systems deliver the drug at specific part of the gastrointestine (GI) as per the pH of GI, resulting in improved patient therapeutic efficacy and compliance. The pH range of fluids in various segments of the GI tract may provide environmental stimuli for drug release. The aim of this study was to design buoyant beads c...

Purpose: Drug microparticles may be microencapsulated with water-insoluble polymers to obtain controlled release, which may be further determined by the particle distribution. The purpose of this study was to determine the drug release parameters needed for the theoretical prediction of the release profiles of single aspirin crystals and their microcapsules. Method: Four single crystals of aspi...

implantable contraceptive is likely to be a promising new option for fertility control, as we have entered the twenty-first century and the world’s population grows by one billion people in a single decade. the main objective of this study was to develop a subdermal implant for levonorgestrol (a synthetic progestin from 19-norandrostanes) using a high molecular weight biodegradable polymer , i....

The purpose of this study was preparation and evaluation of sustained release matrix type ocular mini-tablets of timolol maleate, as a potential formulation for the treatment of Glaucoma. Following the initial studies on timolol maleate powder, it was formulated into ocular mini-tablets. The polymers investigated in this study included cellulose derivatives (HEC, CMC, EC) and Carbopol971P. Mann...

Diclofenac sodium as ophthalmic dosage form is used in patients treatment of eye pain, swelling and redness recovering from cataract surgery but it faces the bioavailability limitation of eye drops due to effective protective mechanisms and corneal barrier functions in the eyes. Therefore, this investigation was aimed to develop ocular film formulations to achieve controlled drug release. Drug ...
