Abstract

An investigation into the design of a directly compressible filler/binder from two locally available raw materials is hereby reported. ‘Nigeria tapioca starch’ (NTS) and ‘Nigeria acacia sieberiana gum’ (NASG) were both extracted using standard methods. The resultant materials were passed through mesh 60 and were then coprocessed in isopropanol and water at ratio of 2:1. NTS and NASG were arbitrarily selected at ratio 90:10, 85:15, and 80:20 which gave flow rates of 5.6, 15.1, and 20.6 g/s; angle of repose of 32.3 o , 30.0 o , and 27.5 o . Compressibility index was 20.9, 17.3 and 6.0 %; while Hausner ratio was 1.21, 1.16, and 1.06, respectively. The composite containing NTS and NASG (80:20) exhibited the best physicochemical properties and was subsequently selected for the ascorbic acid formulations. It was concluded that the coprocessed NASG and NTS have excellent compressibility and compatibility properties and can serve as cost effective excipients in conventional pharmaceutical solid dosage formulations.
