Article history: Received on: 23/05/2013 Revised on: 05/07/2013 Accepted on: 01/09/2013 Available online: 30/09/2013 The main objective of the present work was to develop sustained release matrix tablets of Atenolol. To reduce the frequency of administration and to improve the patient compliance, a once daily sustained release formulation of Atenolol is desirable. So sustained release Matrix Ta...

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 study, matrix-type transdermal patches of glibenclamide were developed using a combination hydrophilic and hydrophobic polymers for investigating the efficacy carriers. A cellulose derivative, HPMC E50, was used as matrix-forming polymer, Eudragit RS 100 polymer. The solvent casting technique employed to develop blend patch formulation chloroform methanol solvent. No drug–polymer intera...

The efficacy of oral aspirin treatment in the secondary prevention of cardio and cerebro vascular disease is well known. However oral administration is often associated with abdominal discomfort. The feasibility of delivering aspirin transdermally from eudragit and polyvinyl acetate (PVA) matrix-type patches to enhance its antithrombotic efficiency of aspirin was investigated. Transdermal films...

Coated hard capsules are becoming increasingly important for a number of reasons such as administration of new active ingredients, oral vaccination, colon drug delivery or their use in preclinical and clinical trials. The independency of coating composition on capsules filling is the major advantage of this dosage form. In our study, two types of hard capsules (gelatin and hypromellose) were co...

Objective: To formulate economic transdermal patch of lornoxicam (LX) and to study its anti-inflammatory activity on acute and chronic inflammatory in rat models Method: Three LX transdermal patches (F1, F2 and F3) consist of Eudragit RL-100 and RS-100 in three different ratios (1:2, 1:1 and 2:1) were prepared respectively by the solvent evaporation technique. All formulations contain diethylph...

The present study reports on the production of low molecular weight heparin (LMWH) loaded polymeric microspheres for delivery via the oral route. The microspheres were prepared by the spray-drying technique using Eudragit as the polymer. The objective of this study was to examine extensively the influence of formulation and process variables on the characteristics of the microspheres prepared. ...

OBJECTIVES Microencapsulation of drugs into preformed polymers is commonly achieved through solvent evaporation techniques or spray drying. We compared these encapsulation methods in terms of controlled drug release properties of prepared microparticles and investigated the underlying mechanisms responsible for the 'burst release' effect. METHODS Using two different pH-responsive polymers wit...

The objective of present investigation is to design a sustained release floating microballoons of Metformin HCl using two polymers of different permeability characteristics Cellulose Acetate Butyrate (MW of 16,000) and Eudragit RS 100 (MW of 150,000) using the oil-in-oil emulsion solvent evaporation method. The prepared microballoons were studied for drug release behavior in simulated gastric f...

The present study has been performed to microencapsulate the antidiabetic drug of Vildagliptin to get sustained release of drug. The attempt of this study was to formulate and evaluate the Vildagliptin loaded microspheres by emulsion solvent evaporation technique using different polymers like Eudragit RL100, Eudragit RS100, Ethyl cellulose, and Methocel K100M. In vitro dissolution studies were ...
