Method II

Add the ether-alcohol theobroma solution all at once to the substance or mixture contained in a mortar; triturate quickly; pass through a No. 20 or No. 30 sieve, and allow to dry by exposure for an hour or two.

Tablet-triturates, or moulded tablets, are made with sugar of milk by means of an apparatus consisting of a flat plate of vulcanite having holes bored into it, which fits upon another vulcanite plate upon which are as many projections as holes, and these projections push out the tablets from the holes. Each tablet generally weighs a fraction over a grain, but the weight of the tablets formed by the mould is determined by making powdered sugar of milk into a paste with proof spirit. The paste should have such a consistency that it will just spread with a spatula. The mould is filled with the paste, the tablets pressed out, dried, and their weight taken. From this the weight of sugar of milk required for the desired number of tablets is calculated, a portion, equal to the bulk of the medicament to be added, being deducted. The medicament is triturated thoroughly with the sugar of milk, made into a stiff paste with proof spirit, and moulded as above directed.
