Use of the angiotensin-(1-9) peptide or derivatives thereof, use of vectors overexpressing the ace2 enzyme that produces angiotensin-(1-9) for preparing medicaments useful for preventing, reverting, inhibiting and/or reducing hypertension and/or inducing vasodilation

Abstract

The present invention is related to the use of the angiotensin-(1-9) peptide or peptides derived therefrom, which are biological or chemical analogs, for preparing medicaments useful for preventing, reverting, inhibiting and/or reducing hypertension and/or inducing vasodilation. Furthermore, this invention also comprises a vector overexpressing the homologous angiotensin-II converting enzyme (ACE2) for elevating the concentration in the blood and/or tissues of the angiotensin-(1-9) peptide. This vector may be adenovirus, retrovirus, lentivirus or adeno-associated virus containing the gene encoding for ACE2. This invention allows the administration of angiotensin-(1-9) or the derivatives thereof in oral form, injectable form, continuous infusion pump, or for increasing its levels in the body by means of the combined treatment with angiotensin-I converting enzyme inhibitors, with angiotensin-II receptor antagonists (ARA II), with Rho kinase inhibitors, with renin inhibitors, with L-type calcium channel antagonists and/or with diuretics.
