Abstract
A method and drug form are provided for increasing the oral absorption of polar bioactive agents such as polypeptides by the oral administration of said polar bioactive agents in a suitable pharmaceutically accepted excipient to which has been added a hydroxyaromatic acid or salt as an adjuvant thereof. The adjuvant is present in the drug form in quantities sufficient to be effective in enhancing the rate of oral absorption of the polar bioactive agents.
