Abstract: The present invention relates to a subcutaneous delivery system comprising a biodegradable polymeric matrix and at least one of the pharmacologically active substances of general formula (I): wherein A represents an amino group —NH2 or an ammonium group —NH3+ or a residue of general formula (II): wherein each of X1 to X5 represents, independently, an hydrogen atom, a linear or branched C1 to C6 alkyl group, a linear or branched C1 to C6 alkyloxy group, a hydroxyl group —OH, an amino group —NH2, a primary or secondary C1 to C6 alkylamino group, a halogen atom, a nitro group —NO2; said substance being embedded into said matrix. It relates also to a process for its preparation and to its use for the preparation of a medicament.

Abstract: The present invention relates to compositions comprising two sustained release formulations, the first being capable of releasing a gonadotropin releasing hormone composition and the second an estrogenic composition. The compositions of the invention can be employed for an improved androgen deprivation therapy of prostate cancer, in which therapy loss of bone mineral density and the occurrence and severity of hot flashes are minimized through the maintenance of a minimally adequate estrogen level.
