Pharmaceutical compositions for poorly soluble drugs
View Patent ↗The present invention provides a pharmaceutical composition of a practically insoluble drug, wherein the composition may be administered with food or without food. The composition may be in the form of a solid dispersion of the practically insoluble drug and a polymer having acidic functional groups, and the composition may in vitro form a suspension.
1. A pharmaceutical composition consisting essentially of about 100 mg of an azole antifungal drug and optionally at least one polymer having acidic functional groups wherein in vivo the composition provides a mean C MAX of at least 100 ng/ml, after administration in the fasted state.
2. A pharmaceutical composition according to claim 1 , wherein said at least one polymer having acidic functional groups is present.
3. A pharmaceutical composition according to claim 1 , wherein in vivo the composition provides a mean C MAX of at least 150 to 250 ng/ml, after administration of the azole antifungal drug in the fasted state.
4. A pharmaceutical composition according to claim 1 , wherein the azole antifungal drug is itraconazole.
5. A pharmaceutical composition consisting essentially of about 100 mg of an azole antifungal drug and optionally at least one polymer having acidic functional groups wherein the composition provides a mean AUC of at least 800 ng.h/ml, after administration in the fasted state.
6. A pharmaceutical composition according to claim 5 , wherein said at least one polymer having acidic functional groups is present.
7. A pharmaceutical composition according to claim 5 , wherein the composition provides a mean AUC of 1300 to 2300 ng.h/ml, after administration of the azole antifungal drug in the fasted state.
8. A pharmaceutical composition according to claim 5 , wherein the azole antifungal drug is itraconazole.
9. A pharmaceutical composition, consisting essentially of:
about 100 mg of an azole antifungal drug; and
one or more polymer having acidic functional groups; and
optionally one or more additional ingredients selected from the group consisting of a disintegrant, a diluent, a filler, an inert solid carrier, an inert solid matrix, a lubricant, a glidant, a colouring agent, a pigment, a flavour, water, ammonia, an alkaline agent, and methylene chloride,
wherein in vivo the composition provides a mean C MAX of at least 100 ng/ml, after administration in the fasted state.
10. A pharmaceutical composition according to claim 9 , which is present in a capsule.
11. A pharmaceutical composition according to claim 9 , in the form of a powder.
12. A pharmaceutical composition, consisting essentially of:
about 100 mg of an azole antifungal drug; and
one or more polymer having acidic functional groups; and
optionally one or more additional ingredients selected from the group consisting of a disintegrant, a diluent, a filler, an inert solid carrier, an inert solid matrix, a lubricant, a glidant, a colouring agent, a pigment, a flavour, water, ammonia, an alkaline agent, and methylene chloride,
wherein in vivo the composition provides a mean AUC of at least 800 ng.h/ml, after administration in the fasted state.
13. A pharmaceutical composition according to claim 12 , which is present in a capsule.
14. A pharmaceutical composition according to claim 12 , in the form of a powder.
15. A pharmaceutical composition, consisting essentially of:
about 100 mg of an itraconazole; and
one or more polymer selected from the group consisting of hydroxypropylmethylcellulose phthalate, polyvinyl acetate phthalate, hydroxypropylmethylcellulose acetate succinate, alginate, carbomer, carboxymethyl cellulose, methacrylic acid copolymer, shellac, cellulose acetate phthalate, starch glycolate, polacrylin, methyl cellulose acetate phthalate, hydroxypropylcellulose acetate phthalate, cellulose acetate terephthalate, cellulose acetate isophthalate and cellulose trimellitate; and
optionally one or more additional ingredients selected from the group consisting of a disintegrant, a diluent, a filler, an inert solid carrier, an inert solid matrix, a lubricant, a glidant, a colouring agent, a pigment, a flavour, water, ammonia, an alkaline agent, and methylene chloride,
wherein in vivo the composition provides a mean C MAX of at least 100 ng/ml, after administration in the fasted state.
16. A pharmaceutical composition, consisting essentially of:
about 100 mg of an itraconazole; and
one or more polymer selected from the group consisting of hydroxypropylmethylcellulose phthalate, polyvinyl acetate phthalate, hydroxypropylmethylcellulose acetate succinate, alginate, carbomer, carboxymethyl cellulose, methacrylic acid copolymer, shellac, cellulose acetate phthalate, starch glycolate, polacrylin, methyl cellulose acetate phthalate, hydroxypropylcellulose acetate phthalate, cellulose acetate terephthalate, cellulose acetate isophthalate and cellulose trimellitate; and
optionally one or more additional ingredients selected from the group consisting of a disintegrant, a diluent, a filler, an inert solid carrier, an inert solid matrix, a lubricant a glidant, a colouring agent, a pigment, a flavour, water, ammonia, an alkaline agent, and methylene chloride,
wherein in vivo the composition provides a mean AUC of at least 800 ng.h/ml, after administration in the fasted state.
