Novel Orally Disintegrating Tablets Produced Using a High-Pressure Carbon Dioxides Process.

abstract：:A series of carbamates of the phenolic compound 1 were prepared and evaluated in vivo as its prodrug. Each carbamate was orally administered to rats, and plasma concentrations of the parent compound 1 were measured with the passage of time. We judged which carbamate was suitable for the prodrug of 1 from both the AUC ...
