BACKGROUND AND THE PURPOSE OF THE STUDY Lovastatin is an antihyperlipidemic agent which has low bioavailability due to the extensive first pass metabolism. It was sought to increase gastric retention of lovastatin by development of a sustained release gastroretentive drug delivery system leading to reduced fluctuation in the plasma concentration and improved bioavailability. MEHODS: Floating m...
Oral Sustained Delivery of Theophylline Floating Matrix Tablets- Formulation and In-vitro Evaluation
The aim of the study was to develop and physicochemicaly characterize single unit controlled delivery system of Theophylline and was formulated as floating matrix tablet by direct compression method using gas generating agent (sodium bicarbonate) and various viscosity grades of hydrophilic polymers (HPMC K15M, K4M; HPC and Carbapol 934P). Formulation was optimized on the basis of buoyancy and i...
Gastroretentive bimodal drug delivery systems of lamotrigine were developed using immediate release and extended release segments incorporated in a hydroxypropyl methylcellulose capsule and in vitro and in vivo evaluations were conducted. In vivo radiographic studies were carried out for the optimized formulation in healthy human volunteers with replacement of drug polymer complex by barium sul...
The purpose of writing this review on Hollow microspheres is to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. Hollow microsphere promises to be a potential approach for gastric retention. The recent developments of FDDS including approaches to design single-unit and multiple-unit floating systems, mechanism of floating mi...
aluminum phosphide (alp) as 3 g tablet is widely used in iran to protect stored food grains from pests. hyperglycemia following its ingestion has been already reported in the recent years but severe hypoglycemia is uncommon. here, we report a 19 year old male who attempted suicide with one tablet of alp and demonstrated severe hypoglycemia. despite restoration of blood glucose concentration to ...
propranolol, a prototypical b-adrenergic receptor antagonist and atenolol, a cardio-selective b-antagonist are widely used in therapeutic regimens for treatment of hypertensive patients. in iran, several pharmaceutical manufacturers formulate these two b-blockers. as the formulation of a dosage form is essential for the patient's safety and drug efficacy, in this study we aimed to evaluate...
Objective: Focus of the study was to formulate Design expert Software assisted floating tablet Bisoprolol Fumarate. Fumarate is a Beta adrenergic blocking agent, used treat cardiac diseases favorable characters be formulated as sustained release Gastro retentive tablets.
 Methods: Floating Tablets were prepared by using polymers such Polyox N 12 K and Carbapol 940 P. Formulations direct co...
ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...
