应用

Adipic acid is an organic acid used for resolving the problem of pH-dependent release of weakly basic drugs.

生化/生理作用

Presence of adipic acid in the urine of ketotic patients is utilized as a marker for diagnosing the degree of ketosis.

制备说明

Adipic acid is freely soluble in ethanol and methanol. It also dissolves in boiling water, and acetone. Additionally, the product is slightly soluble in water and cyclohexane and is practically insoluble in benzene and petroleum ether.

Weakly basic drugs or salts thereof demonstrate pH-dependent solubility. The resulting release from conventional matrix tablets decreases with increasing pH-milieu of the gastrointestinal tract. The aim of this study was to overcome this problem and to achieve pH-independent drug release.
