The effect of triacetin on solubility of diazepam and phenytoin

Riley, Christine Marie, 1964- January 1990 (has links)
The effect of triacetin in combination with common cosolvents on the solubility of phenytoin and diazepam was studied. The cosolvents were PEG 400 and propylene glycol. In addition, the data were used to test the following model: UNFORMATTED EQUATION FOLLOWS: log Sᵈ(c,p,w) = log Sᵈ(w) + f(c)σᵈ(c) + [Sᵖ(w)10(f(c)σᵖ(c))/D(p)] σᵈ(p). UNFORMATTED EQUATION ENDS. The term on the left side of the equation is the solubility of a drug in the ternary system. This is related to the aqueous solubility of the drug, the solubility of the drug in a completely miscible organic solvent (CMOS), and the solubility of the partially miscible organic solvent (PMOS). This model was proposed by Gupta et al. (1989) and predicts the solubility of a ternary system composed of a CMOS and PMOS. The results indicate the triacetin does increase the solubility of the two poorly water-soluble drugs. There is good correlation between the observed and predicted increase in the solubility of the drugs.
