Abstract
Il procedimento mira a preparare una composizione destinata alla liberazione prolungata e controllata di sostanze medicamentose peptiche, che si presenta sottoforma di microsfere in materiale polimero biodegradabile incorporante la detta sostanza medicamentosa.Il procedimento consiste nel convertire prima un peptide o un sale di peptide solubile in acqua in un peptide, rispettivamente un sale di peptide, insolubile in acqua. Le tappe successive comprendono la preparazione di un'emulsione organica acquosa, poi l'estrazione del solvente organico in un eccesso di mezzo acquoso.
