On Disintegration and Dissolution Behaviors of Paracetamol Tablet Formulations

چکیده

mulation and in many cases the bioavailability of drug from tablets has received considerable attention. As part of the efforts to reach international harmonization of pharmaceutical excipients, the Joint Conference on Excipients identified starch as one of the top 10 excipients (1). Starch is a multipurpose excipient in tablet formulation, and it is used as a binder, disintegrant, and filler (2). The relevance of starch mucilage as a binder in the granulation of hydrophobic drug substrates has been established (3). Although cornstarch is the most frequently used excipient in tableting, previous studies of breadfruit and cocoyam have shown some promise (4,5). Preliminary evaluation of these starches following official and unofficial protocols showed that they possess some of the desirable features of good excipients (5–7). Breadfruit and cocoyam starches, respectively, were found to possess superior hydration and moisture sorption capacities when compared with cornstarch BP (4), which suggests their suitability as mucilaginous binding agents. Binders provide the necessary binding force that holds powders together to form granules, which under compression form a tablet. Usually the stronger (i.e., more efficient) the binder,

The Effect of Formulation Variables on the Release Kinetics of Paracetamol Tablet Formulations.

Aim: The objective of this work was to study the effects of formulation variables on the release kinetics of paracetamol tablet formulation. Materials and Methods: Paracetamol tablets were formulated using wet granulation (WG) and direct compression (DC) using two predetermined pressures. Avicel, dicalcium phosphate (DCP) and pregelatinized starch (PGS) were used as directly compressible...

Evaluation of the Disintegrant Properties of Native Starches of Five New Cassava Varieties in Paracetamol Tablet Formulations

The disintegrant potential of native starches of five new cassava (Manihot esculenta Crantz.) varieties developed by the Crops Research Institute of Ghana (CRIG) was studied in paracetamol tablet formulations. The yield of the starches ranged from 8.0 to 26.7%. The starches were basic (pH: 8.1-9.9), with satisfactory moisture content (≤15%), swelling capacity (≥20%), ash values (<1%), flow prop...

Effects of interacting variables on the tensile strength and the release properties of paracetamol tablets

Purpose: The individual and interaction effects of nature of binder (N), concentration of binder (C) and the relative density (D) on the tensile strength and release properties of paracetamol tablets have been studied using a 2 factorial experimental design. Methodology: Khaya gum, which represented the “low” level, and polyvinylpyrrolidone (PVP), which represented the “high” level, was used as...

Evaluation of Abelmoschus starch as tablet disintegrant

Seed starch (16.0%w/w) obtained from Abelmoschus moschatus Linn. (Malvaceae) was employed as a disintegrant to paracetamol tablets at concentrations of 2.5-10.0% w/w. The granules prepared by wet granulation technique were evaluated for percentage of fines and flow properties. Tablet properties including thickness, content uniformity, average weight and weight variation, hardness, friability, d...

A COMPARATIVE STUDY OF THE DISSOLUTION CHARACTERISTICS OF CAPSULE AND TABLET DOSAGE FORMS OF MELT GRANULATIONS OF PARACETAMOL ñ DILUENT EFFECTS

The dissolution characteristics of melt granulations of paracetamol in capsule and tablet dosage form were compared to determine whether the dissolution characteristics of the granules can be actualized by formulating them as rapidly disintegrating tablets. The term melt granulation refers here to the wax-matrix granules that were formed by triturating the drug powder (paracetamol) with a melte...

Influence of process variables on release properties of paracetamol tablets.

A 2(3) factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), binder concentration (c) and relative density of tablet (d) on the disintegration time (DT) and dissolution times, t1, t50 and t90, of paracetamol tablet formulations. The factorial design was also used to study the quantitative effects of pregelatinization ...
