Abstract

Moisture-sensitive powders are granulated for tablet manufacture by admixing with a solution of a prolamine in substantially water-free methanol, ethanol, isopropanol or propanol, subdividing and evaporating the alcohol. Prolamines used are zein from Indian corn, gliadin from wheat and hordein from barley. Prior to tableting, the granules are usually mixed with a lubricant such as magnesium, calcium, zinc or sodium stearate, stearic acid, talc, mineral oil, boric acid, sodium lauryl sulphonate, calcium ricinoleate. Substances tableted are for example, ascorbic acid, sodium bicarbonate-tartaric acid, aureomycin, bacitracin, terramycin, penicillin.
