Drug delivery compositions which are suitable for transvaginal administration for the treatment of diseases and disorders of the urogenital tract are described. The drug delivery compositions are administered directly to the vagina using a convenient transvaginal application that deposits a very small volume of drug at the desired site for delivery. This method of administration reduces the systemic levels of the drugs and decreases the side effects which are associated with systemic administration. In the preferred embodiment, the compositions are in the form of a gel. The formulation is administered in volumes of less than or equal to 1 milliliter. In the preferred embodiment, the composition contains an antimuscarinc drug, such as oxybutynin.
