  • Patent number: 6197345
    Abstract: The foregoing invention relates to a new microbubble preparation and thrombolytic therapy which relies on microbubbles and ultrasound for its lytic activity. The pharmaceutical composition of the invention comprises a liquid solution of microbubbles with an internal atmosphere enhanced with the perfluorocarbon gas which cavitate in the presence of an ultrasound field following intravenous injection or infusion of said composition into said host. For thrombolysis the area of a thrombus is exposed to an ultrasound field in the presence of the microbubbles and significant lysis is experienced. The method and pharmaceutical composition of the invention exhibit thrombolytic properties similar to those of other thrombolytic agents such as urokinase and are less toxic and are clot specific in that they do not introduce a systemic lytic state to a said animal.

  • Patent number: 6168798
    Abstract: The invention provides methods and compositions which are mild and nonirritating for reducing and eliminating skin disorders, particularly blemishes and redness associated with acne. The hydroalcoholic compositions of the invention contain a keratolytic compound, preferably a &bgr;-hydroxy carboxylic acid, more preferably salicylic acid or pharmaceutically acceptable salt thereof; and a glycerophosphate ester or salt, formulated with pharmaceutically acceptable carriers. Preferred glycerophosphate salts for use in the methods and compositions of the invention are sodium glycerophosphate and calcium glycerophosphate. Additional anti-irritancy agents are not required in the compositions of the present invention, as the glycerophosphate salt component uniquely endows the compositions with nonirritant properties.

  • Patent number: 6165445
    Abstract: There is provided novel pharmaceutical compositions containing tyloxapol as the active ingredient. These formulations comprise tyloxapol at concentrations above 0.125%, preferably from about 0.25% to about 5.0%. In addition, the invention encompasses pharmaceutical compositions having reduced hypertonicity which compositions comprise tyloxapol in pharmaceutically acceptable solutions without significant concentrations of hypertonic agents or other active ingredients NaHCO.sub.3, or active phospholipids, such as DPPC. The less hypertonic formulations allow one to derive all the benefits of the active ingredient tyloxapol, such as its reduced toxicity and enhanced half-life, while avoiding or reducing side effects, such as bronchospasms, associated with the various hypertonic agents or other active ingredient agents.

  • Patent number: 6162460
    Abstract: Disclosed is a poultice capable of rapidly curing an affected part of a patient's body and of enhancing a curative value by increasing an infiltration efficiency of medicine into a hypodermic tissue of the affected part with the aid of a low-frequency electro therapy. Both surfaces of compress sheets of the poultice are coated with predetermined skin-adhesive medicines adapted to cure an affected part of a patient's body. A thin film is attached to lower surfaces of the compress sheets. The thin film can be detached from the lower surfaces of the compress sheets during use of the poultice. An attaching sheet for attaching the poultice to the affected part of the patient's body is located on upper surfaces of the compress sheets. A pair of conductive layers are coated on a lower surface of the attaching sheet, which is opposite to the upper surfaces of the compress sheets. A low-frequency oscillator for applying a low-frequency energy into the compress sheets is installed between the conductive layers.
