Regional delivery increases comfort and bioavailability of the drug, resulting in rapid and relatively high blood levels in the regions to be treated in the substantial absence of side effects due to the high levels required for efficacy following systemic delivery. In the preferred embodiment, these formulations consist of drug micro or nanoparticles, which may be formed of drug alone or in combination with an excipient or polymeric carrier. The excipient or polymer may be used to manipulate release rates and to increase adhesion to the affected region. The drug formulation can be applied as a dried powder, a liquid suspension or dispersion, or as a topical ointment, creme, lotion, foam or suppository.

  • Patent number: 6645508
    Abstract: A stable composition including a water-sensitive pharmacologically active agent, such as an enzyme, an antibiotic or a vitamin, a hydrophilic non-polar primary solvent, an optional hydrophilic non-polar secondary solvent and optional pharmaceutical or cosmetic adjuvants to enhance appearance for topical use. Where the water-sensitive or water-degradable component is L-Ascorbic acid and the principal solvent is N-methyl-2-pyrrolidone (“NMP”) the composition is stable for many months at a concentration of L-Ascorbic acid of up to about 40 % w/v. This composition using NMP as a solvent and enhancer of skin penetration together with appropriate adjuvants is useful for preparing dermatological topical dosage for cosmetic and therapeutic purposes.

  • Patent number: 6638495
    Abstract: Stabilized dispersions are provided for the delivery of a bioactive agent to the respiratory tract of a patient. The dispersions preferably comprise a plurality of perforated microstructures dispersed in a suspension medium that typically comprises a hydrofluoroalkane propellant. As density variations between the suspended particles and suspension medium are minimized and attractive forces between microstructures are attenuated, the disclosed dispersions are particularly resistant to degradation, such as, by settling or flocculation. In particularly preferred embodiments, the stabilized dispersions may be administered to the lung of a patient using a metered dose inhaler.
