DOCUMENT TYPE: Conference CA Section: 64 (Pharmaceutical Analysis) Eleven phenothiazine derivs., such as triphthazine [117-89-5], diprazin [58-33-3], and fluorphenazine [69-23-8], were detd. in powders, lozenges, and ampul solns. by dissolving in MeOH, acidification with dil. H2SO4, and titrn. with 0.1N Ce(SO4)2. This method is simple, rapid, and has a relative error of .+-. 0.19-1.5%. .

Diffusion rates of active principles from dermal pharmaceuticals

Diffusion rates of active principles from dermal pharmaceuticals. Ali, J.; Dobrecky, J.; Gomez, J. C.; Lopez, E. L.; Manjon, F.; Murillo, P.; Salamano, B. (Fac. Farm. Bioquim., UNBA, Buenos Aires, Argent.). Rev. Farm. (Buenos Aires), 124(1-12), 11-12 (Spanish) 1982. CODEN: RFABAN. ISSN: 0034-9496. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) The diffusion rate of promethazine [60-87-7] or promethazine-HCl [58-33-3] in oil-in-water emulsions was greater than in water-in-oil emulsions. The diffusion rate was also affected by the soly. of the active ingredient in the receptor medium and the surfactant used.
