  • Patent number: 5684038
    Abstract: A process and pharmaceutical composition for the prevention and treatment of cutaneous Type I hypersensitivity reactions in humans is disclosed. The pharmaceutical composition comprises of a chromone compound of the following formula, or a pharmacologically acceptable salt, ester or amide thereof: ##STR1## dissolved or dispersed in a pharmacologically acceptable carrier. In accordance with the process, a preventively or therapeutically effective amount of the composition is topically administered to a human patient, as required; i.e. for prevention the composition is administered to the area of skin susceptible to exposure to antigen and for treatment the composition is administered to the reaction site.

  • Patent number: 5672358
    Abstract: A controlled release aqueous emulsion is disclosed, as are its method of manufacture and use as a vehicle for delivering medicaments in liquid form. A contemplated emulsion comprises an oil-in-water emulsion having an average oil particle size of about 100 nm to about 250 nm, a pH value of about 4.5 to about 8.0 and a viscosity at 20.degree.-25.degree. C. of 1 to about 1000 cps. The water phase constitutes at least 25 weight percent of the total composition. The oil phase is a wax matrix that is a wax having a melting point of about 40.degree. to about 80.degree. C. and is present in an amount of about 3 to about 30 percent of the total composition. A pharmaceutically effective amount of a pharmacologically active compound that is free from decomposition at a temperature below about 90.degree. C. is dissolved or dispersed in the wax matrix. The oil and water phases are emulsified by an emulsifying agent that provides freedom from phase separation at a pH value of about 4.

  • Patent number: 5626879
    Abstract: The present invention contemplates a dry, granular terfenadine composition. That composition comprises (i) particulate terfenadine and (ii) a polyethylene oxide-polypropylene oxide-polyethylene oxide block copolymer having an HLB number of 24 that is a wetting agent for the terfenadine that are dry-blendedly dispersed onto (iii) spray-dried sorbitol particles that are loosely packed, randomly oriented filamentary crystals having pores that entrap the particulate terfenadine and wetting agent upon the dry-blended dispersal. The weight ratio of particulate terfenadine to the block copoymer is about 1:1 to about 1:5:1, and the weight ratio of terfenadine to the spray-dried sorbitol is about 1:4 to about 1:10. The composition is free-flowing and is substantially free from the taste of solubilized terfenadine when placed on the human tongue in dry form or when dispersed in water and tasted within about five minutes of said dispersal.
