Investigation of excipients’ nature influence on the quality indices of effervescent tablets of acetylsalicylic acid, paracetamol and ascorbic acid

Abstract

The priority objective of pharmaceutical science remains the creation and rational use of medicines. In recent years among these medicines particular attention is paid to the form of sparkling (fast-dissolving, gaseous or effervescent) solid dosage forms – tablets, granules, powders, microspheres, capsules, suppositories and others. In the development of effervescent tablets, which are absent in the domestic market, a combination of acetylsalicylic acid, paracetamol and ascorbic acid was selected for experimental studies. The purpose of the work is to study the influence of excipients on the pharmaco-technological properties of effervescent tablets of acetylsalicylic acid, paracetamol and ascorbic acid. Materials and methods. In the course of the experiment, nine excipients from groups of fillers, leavens and binders were investigated. By studying qualitative factors, one of the plans of dispersion analysis was used, namely a three-factorial experiment based on the Hyper-Greek-Latin square. In experiments we used modern equipment for determining the bulk density of powders (ERWEKA GT, Germany), bulk density (ERWEKA SVM 202, Germany), tablet press (Korsh XL-100, Germany), uniformity of the weight of tablets (Mettler Toledo AB54-S, Switzerland), crushing resistance (ERWEKA TBH-525 WTO, Germany), abradability (ERWEKA TAR 200, Germany), disintegration time (ERWEKA ZT 33, Germany). Results. As a result of the statistical processing of experimental results, the influence of excipients on the pharmaco-technological parameters of mass for tableting (bulk density, density after compression, Carr's index, flow ability, slope angle), tableting process, tablet appearance, mass uniformity, abradability, resistance to crushing, disintegration and transparency of the solution were investigated. Conclusions. The influence of nine excipients on the pharmaco-technological characteristics of effervescent tablets of acetylsalicylic acid, paracetamol and ascorbic acid was studied. One-dimensional leaders for most of the investigated pharmaco-technological parameters are anhydrous lactose (SuperTab ® 22AN), crospovidone XL-10, sodium stearyl fumarate (Pruv ® ). The obtained results are the basis for the development of the optimal composition of effervescent tablets of acetylsalicylic acid, paracetamol and ascorbic acid.
