Abstract

Alfuzosin compositions comprising alfuzosin and a release-retarding matrix comprising about 40 to about 80% (by weight) hydroxypropyl methyl cellulose with a maximum apparent viscosity of about 5600 cP, wherein the compositions are bioequivalent to the reference dosage form of NDA #021287 are disclosed. Alfuzosin compositions comprising alfuzosin and a release-retarding matrix comprising about 40 to about 80% (by weight) hydroxypropyl methyl cellulose (HPMC) with a maximum apparent viscosity of about 5600 cP, wherein the dissolution profile of the compositions are substantially identical to the dissolution profile of the reference dosage form of NDA #021287 are also disclosed. Methods of making and using the alfuzosin compositions are also disclosed.

Claims (43)

alfuzosin; and

a release-retarding matrix comprising about 40 to about 80% (by weight, based on the total weight of the alfuzosin composition) hydroxypropyl methyl cellulose (HPMC) 2208 with a maximum apparent viscosity of about 5600 cP.

2 . The alfuzosin composition of claim 1 , wherein the release-retarding matrix comprises about 40 to about 70% HPMC 2208 with an apparent viscosity of about 3000 to about 5600 cP.

3 . The alfuzosin composition of claim 2 , wherein the release-retarding matrix comprises about 40% HPMC 2208 with an apparent viscosity of about 3000 to about 5600 cP.

4 . The alfuzosin composition of claim 2 , wherein the release-retarding matrix further comprises about 10 to about 40% HPMC 2208 with an apparent viscosity of about 80 to about 120 cP.

5 . The alfuzosin composition of claim 1 , wherein the composition comprises about 10 mg alfuzosin and after a single administration of the composition to a population of at least 12 individuals,

a geometric mean of logarithmic transformed AUC 0-t for alfuzosin is within about 70% to about 143% of about 213 hr*ng/ml under fed conditions or of about 136 hr*ng/ml under fasting conditions;
