Because the fluid hydrocarbon portion is absorbed with the particles, the paste is fewer greasy [14].

In the last thirty yrs, given that the expense and issues involved with promoting new drug entities have greater, with concomitant recognition of the therapeutic advantages of controlled drug-delivery, greater focus continues to be focused on progress of sustainedor controlled-release drug-delivery systems.
