Hydrodynamically Balanced Systems (HBS): Innovative Approach of Gastroretention: A Review
The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. The recent developments of FDDS including the physiological and formulation variables affecting gastric retention, approaches to design single-unit and multiple-unit floating systems, and their ...
متن کاملHydrodynamically Balanced Systems ( Hbs ) : Innovative Approach of Gastro Retention : a Review
The objective of writing this review on hydrodynamically balanced systems (HBS) was collection of the recent literature. The design of hydrodynamically balanced drug delivery system is base on prolong GI residence time of drug in an area of the GI tract to maximize drug reaching its absorption. Gastrointestinal transit time of orally administered dosage forms are controlled by using gastro rete...
متن کاملFormulation and Evaluation of Hydrodynamically Balanced System for Verapamil Hydrochloride- Gastro Retentive Approach
Objective: The aim of present investigation was to develop HBS system (sustained release) for Verapamil HCl used for the treatment of hypertension. The drug delivery system was designed to retain the system in stomach so that increase in absorption of drug and decrease in dosing interval. Methodology: Single unit capsules were filled with weighed mixture of Verapamil HCl and polymers such as HP...
متن کاملFormulation and in vitro evaluation of Hydrodynamically balanced system for theophylline delivery
The objective of the present study was to formulate hydrodynamically balanced systems (HBSs) of theophylline as single unit capsules. They were formulated by physical blending of theophylline with hydroxypropyl methyl cellulose, polyethylene oxide, polyvinyl pyrrolidone, ethyl cellulose, liquid paraffin, and lactose in different ratios. These theophylline HBS capsules were evaluated for weight ...
متن کاملHydrodynamically Balanced Gastro-Retentive Site Specific Drug Delivery System: An Innovative Approach
Conventional oral dosage forms suffer with many disadvantages. To avoid such limitations controlled release dosage forms are preferred. When these controlled release dosage forms administered by oral route retained in the stomach and release the drug in a controlled fashion continuously in gastrointestinal tract [1]. Controlled release systems also suffer with some limitations such as short gas...
