Abstract

Sustained release pharmaceutical tablets are prepared by admixing in a dry state a medicament and a comminuted, pharmaceutically acceptable, substantially water insoluble, sustained release, lipid material which has a melting point in the range of 40 DEG to 100 DEG C. and is resistant to disintegration and slowly dispersible in the gastrointestinal tract, said comminuted material having a particle size of from 10 to 1500 microns, and compressing the mixture so formed into a tablet. The mixture may include a filler and a lubricant; fillers specified are calcium carbonate, lactose, powdered sugar, kaolin, magnesium carbonate, barium sulphate, diatomaceous earth and calcium sulphate dihydrate, and as lubricants stearic acid, magnesium stearate, sodium stearate, calcium stearate, talc and sodium benzoate. Many types of waxes, fatty acid esters including glycerides, fatty acids and fatty alcohols are given as examples of the sustained release, lipid material; the preferred materials are hydrogenated castor oil, glyceryl monostearate, glyceryl distearate, 12-hydroxy-stearyl alcohol and microcrystalline wax. Specified medicaments are acetaminophen, acetyl salicylic acid, aminophylline, chlorpromazine, prochlorperazine maleate, salicylamide, secobartical, trans-2-phenylcyclopropylamine and tetracycline. In one Example, a sustained release tablet comprises acetaminophen and salicylamide together.
