  • Patent number: 5891458
    Abstract: The invention relates to a muco-adherent, soluble device for administering active ingredients, a method of using said device, and an improved method of manufacturing said device using a continuous, enclosed mixing device capable of operating under pressure. The devices of the invention, which comprise a lyophilized foam and an active ingredient, have a dissolution time of at least about 8 hours, and preferably at least about 24 hours, and can provide for the sustained and/or controlled release of an active ingredient for up to about 24 hours.
    Type: Grant
    Filed: September 15, 1997
    Date of Patent: April 6, 1999
    Inventors: Peter Britton, Patricia Flanagan, William P. Hart, Deborah Linkin
  • Patent number: 5863553
    Abstract: The invention relates to an intravaginally-dissolvable contraceptive suppository, a method of using said suppository, and an improved method of manufacturing said birth control device. The suppositories of the invention, which comprise a lyophilized foam and a contraceptive, have a dissolution time of at least about 2 hours, and up to about 24 hours, and provide superior protection against pregnancy.

  • Patent number: 5505961
    Abstract: A method is disclosed for increasing the solubility of acetaminophen alone or in combination with antihistamines, antitussives, decongestants, and expectorants to form a clear solution for encapsulation into a softgel. The acetaminophen is solubilized alone or in combination with the above ingredients by mixing with polyethylene glycol, propylene glycol, water, polyvinylpyrrolidone and potassium (or sodium) acetate. This invention increases the solubility of the acetaminophen to obtain the same size softgel for a 325 mg dose as is presently available for a 250 mg dose softgel product. The disclosed solvent system is useful because it provides for a highly concentrated solution of acetaminophen capable of encapsulation in a small enough capsule to permit easy swallowing.
