The prior art lacks a formulation, application or product of D-Ala7-Angiotensin-(1-7) (A-779) and analogues and derivatives, D-Pro7-Angiotensin-(1-7) and analogues or derivatives or of Ang-(1-7) analogues or derivatives using cyclodextrins, liposomes, biodegradable polymers and its derivatives for the study or treatment of arterial hypertension and other cardiovascular diseases, wounds, burns, arrhythmia, tumors, diabetes mellitus, sperm mobility, nephropathy, gastrointestinal and gynaecologicalgynecological disorders, angiogenesis, angioplatsy, alopecia and blood diseases in warm blooded animals, or as ligands for de G-protein-coupled receptor MAS. This characterizes the present invention as a more effective option for the study and treatment of pathologies associated or not to this receptor. A combination of two different technologies are provided: the molecular encapsulation of the peptide angiotensin-(1-7) and its analogues and derivates in cyclodextrin and the microencapsulation in biodegradable polymers and liposomes. It is also characterized by the increase of this peptides and its analogues and derivatives using the formulation.
