The effect of small-scale preparation techniques on the diffusion of salicylic acid from ointment bases was studied. The method of mechanical incorporation of the drug in cold petrolatum base, using a spatula, appeared to result in higher rates of salicylic acid diffusion than those encountered with

0 Water, alcohol, and dimethyl sulfoxide were each incorporated at 1,2, and 5 concentrations into four ointment bases containing atropine. The diffusion of drug from five samples of each base was determined at 20-min. intervals for 2 hr. The diffusion process was zero order after 20 min. In the majo
The effect of various starches (corn, potato, rice, arrowroot, and a compressible starch) on the rate of dissolution of salicylic acid from tablets (prepared by double compression) was investigated. Dissolution rate determinations were carried out using three different test methods: USP-NF Method Ty
