Accelerated stability studies of amaranth (FD & C Red No 2) [915-67-3] solution in the presence of some excipients commonly used in pharmaceutical formulations, namely, lactose [63-42-3], mannitol [69-65-8], syrup, gelatin, Tween 80 [9005-65-6], polyethylene glycol (PEG 6000, 4000 and 1500) [25322-68-3] and some drugs, namely, ascorbic acid [50-81-7], chlorpheniramine maleate [113-92-8], antazoline-HCl [2508-72-7], chlorpromazine-HCl [69-09-0] and diphenhydramine-HCl [147-24-0], were carried out at 60°. The dye solution itself was very stable. Lactose and mannitol did not produce marked effects on dye stability. Syrup and gelatin caused fading of the dye solution Complete discoloration of the dye solutions resulted in the presence of Tween 80, PEG 6000, 4000, and 1500 after storage of 12-48 h. Diphenhydramine-HCl, antazoline-HCl and chlorpheniramine maleate did not affect the stability of the dye. On the other hand, ascorbic acid caused fading of the dye solution within few hours. Chlorpromazine-HCl gave a faint pinkish violet colloidal solution when mixed with the dye solution
