A pharmaceutical composition comprising a drug which is an organic nitrogen compound of basic reaction and which is effective against a tropical disease, in admixture with a polymeric matrix of a copolymer of the compound of Formula I. with at least one comonomer having more than one functional group selected from the group consisting of hydroxyl and carboxyl groups.
Claim 2
Dependent Claim
59 words
A pharmaceutical composition comprising a drug which is an organic nitrogen compound of basic reaction and which is effective against a tropical disease, in admixture with a polymeric matrix of a copolymer of the compound of Formula I. with at least one comonomer having more than one functional group selected from the group consisting of hydroxyl and carboxyl groups.
Claim 3
Dependent Claim
27 words
A pharmaceutical composition according to claim 1, in which the polymeric matrix is a copolymer of glycerol and the compound of Formula I defined in claim 1.
Claim 4
Dependent Claim
