| 20110212927 | CARBONATE PRODRUGS AND METHODS OF USING THE SAME - The present invention provides carbonate prodrugs which comprise a carbonic phosphoric anhydride prodrug moiety attached to the hydroxyl or carboxyl group of a parent drug moiety. The prodrugs may provide improved physicochemical properties over the parent drug. Also provided are methods of treating a disease or condition that is responsive to the parent drug using the carbonate prodrugs, as well as kits and unit dosages. | 09-01-2011 |
| 20110212926 | WATER-SOLUBLE ACETAMINOPHEN ANALOGS - The present invention provides water-soluble acetaminophen prodrugs and formulations which may be suitable for parenteral administration. Methods of treating a disease or condition responsive to acetaminophen (such as fever and/or pain) using the acetaminophen prodrugs, as well as kits, unit dosages, and combinations with additional pharmaceutical agent(s) are also provided. | 09-01-2011 |
| 20110196043 | METHODS AND COMPOSITIONS FOR ADMINISTRATION OF TRPV1 AGONISTS - Compositions are provided that contain a TRPV1 agonist, such as capsaicin, and a solvent system. Topical application of the composition results in rapid delivery of agonist to the dermis and epidermis. Method of using the compositions for reducing nociceptive nerve fiber function in subjects, and for treatment of capsaicin-responsive conditions are also provided. | 08-11-2011 |
| 20110184069 | METHODS AND COMPOSITIONS FOR ADMINISTRATION OF TRPV1 AGONISTS - Compositions are provided that contain a TRPV1 agonist, such as capsaicin, and a solvent system. Topical application of the composition results in rapid delivery of agonist to the dermis and epidermis. Method of using the compositions for reducing nociceptive nerve fiber function in subjects, and for treatment of capsaicin-responsive conditions are also provided. | 07-28-2011 |
| 20110182972 | LOW-CONCENTRATION CAPSAICIN PATCH AND METHODS FOR TREATING NEUROPATHIC PAIN - Described here are patches and methods for treating neuropathic pain. In some variations, the neuropathic pain-relieving patch comprises capsaicin or a capsaicin analog, wherein the concentration of the capsaicin or capsaicin analog is less than 1% by weight, and a penetration enhancer, wherein the patch is capable of relieving neuropathic pain over a sustained period of time. The penetration enhancer may be any suitable penetration enhancer. The patches may also include oils, viscosity increasing agents, and the like. In some variations, the pain-relieving patches comprise capsaicin, or an, wherein the concentration of the capsaicin or analog is less than 1%, and a penetration enhancer, whereby delivery of capsaicin from the patch continues for at least an hour, and whereby a single use of the patch provides a therapeutic benefit for at least one month, two months, or three months. Methods for treating neuropathic pain are also described. | 07-28-2011 |
| 20100269858 | COMPOSITIONS AND KITS FOR THE REMOVAL OF IRRITATING COMPOUNDS FROM BODILY SURFACES - The invention provides compositions, methods and kits for the removal of harmful or irritating substances from bodily surfaces. Kits may include a composition containing capsaicin and a capsaicin-cleansing composition, e.g., a composition in which capsaicin is soluble. | 10-28-2010 |
