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.
