Statistical Properties of the Dissolution Test of USP

چکیده
Introduction The dissolution test as defined in the United States Pharmacopoeia (1) is used in judging the quality of pharmaceutical products. Dissolution testing is a method for evaluating physiological availability that depends upon having the drug in a dissolved state. The USP Dissolution testing involves three stages and the acceptance criteria are defined for each stage as a function of a quantity Q,a percentage of the label value that is established for each drug product in its monograph. Acceptance criteria are shown in Table 1. These acceptance criteria are complex and the behavior of the test for samples of varying quality levels is not easily predictable from the knowledge of its drug properties. Pharmaceutical manufacturers are interested in many of the statistical properties of the dissolution test. The following aspects of immediate release dissolution were studied:

Experimental and Computational Study on Hydrodynamic of a Downscaled Mini Vessel USP Dissolution Test Apparatus II
Although not listed on the United States Pharmacopeia (USP), like standard USP 2, small volume USP 2 dissolution apparatus has gained a great deal of attention, especially for cases where small amount of drug product is available for testing in research and design step or evaluations are to be made on a tablet containing trace amounts of the active pharmaceutical ingredient. In this work, first...
متن کاملComparative Dissolution of Diltiazem Immediate and Extended Release Products Using Conventional USP and Innovative Dissolution Paddles
Drug dissolution studies are commonly conducted using compendial methods employing USP Paddle and Basket apparatuses. In many cases, dissolution studies can be of limited benefit especially for product-dependent dissolution procedures like in extended release (ER) formulations. The high variability in dissolution testing, that is not productrelated, emphasizes the need for developing new method...
متن کاملInvestigation of Solid Dispersion Technique in Improvement of Physicochemical Characteristics of Ibuprofen Powder
Ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), eudragit RS PO, eudragit RL PO and hydroxypropylmethylcellulose (HPMC) as carriers to improve physicochemical characteristics of ibuprofen. The prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissoluti...
متن کاملImproving the dissolution properties of spironolactone using liquisolid technique
In this study the effect of liquisolid technique on the dissolution profile of spironolactone was evaluated. Different formulations of spironolactone liquisolid compacts were prepared using various amounts of non-volatile vehicles (Poly ethylene glycol 400 and glycerin). The ratio of microcrystalline cellulose (as carrier) to silica (as coating powder material) was 20 for all formulations. Afte...
متن کاملEffect of Polymorphism and Application of Kinetic Models for the Evaluation of In Vitro Dissolution Profiles of an Eletriptan Hydrobromide Formulation
The intent of this work was to study the effect of polymorphism on dissolution properties and to apply several methods to evaluate the dissolution profiles of immediate-release tablets containing alpha (α) and beta (β) forms of eletriptan hydrobromide (EH). The polymorphs were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and diffuse reflectance infrared Fou...
