  • Pulmonary delivery of active agents
    Publication number: 20030072740
    Abstract: The present invention provides methods for administering an active agent to an animal in need of the agent by the pulmonary route. This method comprises administering via the pulmonary route, a composition comprising (a) an active agent and (b)(i) an acylated amino acid, (ii) a sulfonated amino acid, or (iii) a combination of (i) and (ii). Administration of the compositions of the present invention provide improved pulmonary delivery and greater bioavailability of the active agent than administration of the active agent alone. As a result, lesser amounts of the active agent may be administered to obtain a desired result when contained in the composition of the present invention than when administered alone.

  • Method of preparing alkylated salicylamides
    Patent number: 6399798
    Abstract: The present invention relates to a method of preparing an alkylated salicylamide from a protected and activated salicylamide (hereinafter referred to as a “protected/activated salicylamide”). The method comprises the steps of (a) alkylating the protected/activated salicylamide with an alkylating agent to form a protected/activated alkylated salicylamide, and (b) deprotecting and deactivating the protected/activated alkylated salicylamide, simultaneously or in any order, to form the alkylated salicylamide. The alkylated salicylamides prepared by this method are suitable for use in compositions for delivering active agents via oral or other routes of administration to animals.
