Tabletting Properties of Musol; A New Direct Compression Vehicle

Abstract

A new autocompressible vehicle, Musol, obtained by chemical modification of an edible seed polysaccharide was evaluated for direct compression properties, A Hausner ratio of 1,2 and percent compressibility of 16.7 obtained for Musol indicate that it has very good flow properties. Musol showed superiority over Avicel PH 101, USP Fast-Flo lactose, and Encompress when evaluated in terns of flow rake of powders and moisture sorption by both powders and their slugs, Compacts prepared with Musol were found to disintegrate by erosion and therefore did not perform as well as either alginic acid or Ac-disol in 250 mg Sulphadimidine tablets. However, good drug release was obtained from aspirin tablets containing 5% w/w Musol as a dry binder. The t₅₀, t₉₀ and Dissolution efficiency were as good as the values obtained with 5% w/w Avicel PH 101, A 50/50 blend of Musol and Avicel PH 101 surpassed other blends in performance.
