Compositions and methods of use of ritonavir for treating HCV
View Patent ↗The present invention discloses compositions and a method of improving the pharmacokinetics of pharmaceutical agents (or pharmaceutically acceptable salts, esters, and prodrugs thereof) which are metabolized by cytochrome P450 monoxygenase comprising coadministering ritonavir or a pharmaceutically acceptable salt, ester, and prodrug thereof.
1. A pharmaceutical coadministered composition comprising 3-[2-(3-tert-butyl-ureido)-3,3-diemthyl-butyryl]-6,6-dimethyl-3-aza-bicyclo[3.1.0]hexane-2-carboxylic acid (2-carbamoyl-1-cyclobutylmethyl-2-oxo-ethyl)-amide (SCH 503034) or a salt, ester, or ester thereof and ritonavir or a salt, ester, or ester thereof.
2. The method for improving the pharmacokinetics of 2-(2-{2-cyclohexyl-2[(pyrazine-2-carbonyl)-amino]-acetylamino}-3,3-dimethyl-butyryl)-octahydro-cyclopenta[c]pyrrole-1-carboxylic acid(1-cyclopropylaminooxalyl-butyl)-amide (VX-950), or a salt, ester, or ester thereof comprising coadministering 2-(2-{2-cyclohexyl-2[(pyrazine-2-carbonyl)-amino]-acetylamino}-3,3-dimethyl-yl-butyryl)-octahydro-cyclopenta[c]pyrrole-1-carboxylic acid(1-cyclopropylaminooxalyl-butyl)-amide (VX-950) or a salt, ester, or prodrug thereof with ritonavir or a salt, ester, or ester thereof.
3. The method for improving the pharmacokinetics of 3-[2-(3-tert-butyl-ureido)-3,3-diemthyl-butyryl]-6,6-dimethyl-3-aza-bicyc-lo[3.1.0]hexane-2-carboxylic acid (2-carbamoyl-1-cyclobutylmethyl-2-oxo-ethyl)-amide (SCH 503034) or a salt, ester, or ester thereof comprising coadministering 3-[2-(3-tert-butyl-ureido)-3,3-diemthyl-butyryl]-6,6-dimethyl-3-aza-bicyc-lo[3.1.0]hexane-2-carboxylic acid (2-carbamoyl-1-cyclobutylmethyl-2-oxo-ethyl)-amide (SCH 503034) or a salt, ester, or prodrug thereof with ritonavir or a salt, ester, or ester thereof.
4. The composition of claim 1 coadministered with one or more pharmaceutical agents selected from the group consisting of interferon alpha-2a, interferon alpha-2b, pegylated interferon, pegylated interferon alpha-2a, pegylated interferon alpha-2b, concensus interferon alpha, pegylated concensus-inteferon alpha, interferon fused to a protein, ribavirin, and viramidine.
5. A pharmaceutical coadministered composition comprising 2-(2-{2-cyclohexyl-2[(pyrazine-2-carbonyl)-amino]-acetylamino}-3,3-dimethyl-butyryl)-octahydro-cyclopenta[c]pyrrole-1-carboxylic acid(1-cyclopropylaminooxalyl-butyl)-amide (VX-950) or a salt or ester thereof and ritonavir or a salt, ester, or prodrug thereof; wherein said composition is coadministered with one or more pharmaceutical agents selected from the group consisting of interferon alpha-2a, interferon alpha-2b, pegylated interferon, pegylated interferon alpha-2a, pegylated interferon alpha-2b, concensus interferon alpha, pegylated concensus-inteferon alpha, interferon fused to a protein, ribavirin, and viramidine.
