Abstract: The formulation disclosed herein has beneficial properties in enhancing the solubility and permeability (flux) of at least one of vardenafil, sildenafil, and/or related phosphodiesterase inhibitors or other ionizable compounds. In particular, the formulation confers beneficial properties for compounds in crossing the mucosal membrane, leading to an effective plasma drug concentration. In some embodiments, the formulation comprises an organic-aqueous solvent, which may include at least one of an alcohol, a polyether, diethylene glycol monoethyl ether, a medium chain glyceride, one or more saturated polyglycolyzed C8-C10 glyceride, and/or organic salts, or any combination thereof. In some embodiments, the formulation has a pH of about 3.5 to about 8.0. Also disclosed herein is a use for the formulation in administering one or more compound for the treatment of erectile dysfunction or other diseases, wherein the one or more compound is administered transmucosally (intranasally or sublingually).

Abstract: A method for enhancing absorption of a compound in a medicament that is suitable for administering transmucosally to a subject is conducted in an environment having a suitable pH. The suitable pH is determined based on the ionization constant (dissociation constant) of the compound in water, the solubility of the ionized form of the compound, and the solubility of the non-ionized form of the compound.
