Suppository Dissolution Utilizing USP Apparatus
Standardized in-vitro dissolution testing of suppositories has been of interest to the pharmaceutical industry since the early works of Giabaldi and Gundhofer in 1975.(1) Anthony Palmieri exam ined standard izin g suppository dissolutions in his work at the University of Wyoming (2). Palmieri developed a slotted dissolution basket for suppositories that is ---------widely used by many individua...
متن کاملCalibration—the Usp Dissolution Apparatus Suitability Test
This report summarizes some trends observed in drug dissolution testing, based upon the United States Pharmacopeia (USP) dissolution Apparatus Suitability Test results and the preliminary data obtained from an international collaborative study to assess the pharmaceutical quality of furosemide products in different countries. Based on the USP calibrator data submitted by the participants, repre...
متن کاملHydrodynamic Complexity Induced by the Pulsing Flow Field in USP Dissolution Apparatus 4
USP dissolution Apparatus 4 can have a pulsing or non-pulsing flow, with most commercial apparatus employing a pulsing flow. Overall, a low velocity flow field is present, particularly in the larger 22.6-mm diameter cell. Dissolution data, computational fluid dynamics (CFD), and imaging methods are used and discussed to investigate the effects of low velocity pulsing flow on dissolution. Local ...
متن کاملA Comparison of Dissolution Testing on Lipid Soft Gelatin Capsules Using USP Apparatus 2 and Apparatus 4
Introduction Soft gelatin capsule (SGC) formulations are becoming more popular in recent years (1,2). These formulations can mask odors and unpleasant tastes,and are easy to swallow. They are suitable for encapsulation of lipid solutions,suspensions,or paste-like formulations,making them a useful option when formulating poorly water-soluble drugs. Due to the unique properties of SGC formulation...
متن کاملA novel USP apparatus 4 based release testing method for dispersed systems.
A novel dialysis adapter has been developed for USP apparatus 4 for in vitro release testing of dispersed system dosage forms. This USP apparatus 4 method was optimized and compared with currently used dialysis and reverse dialysis sac methods. Optimization studies for the USP apparatus 4 method showed that release from solution, suspension and liposome formulations was not flow rate limited an...
