English Abstract


A method of treating a patient suffering from peripheral vascular disease,
peripheral neuropathies, or autonomic neuropathies by administering a cGMP
PDE5 inhibitor such as sildenafil. The method is particularly applicable to
patients suffering from diabetic foot ulcers, Raynaud's Phenomenon, CREST
Syndrome, erythromatosis, rheumatoid diseases, diabetic retinopathies and
onychiomycosis. According to the present invention, a cGMP PDE5 inhibitor may
be administered as a prophylactic to patients predisposed to develop a
peripheral vascular disease, peripheral neuropathy or autonomic neuropathy.


French Abstract

L'invention concerne une méthode de traitement destinée à un patient souffrant d'une maladie vasculaire périphérique, de neuropathies du système nerveux périphérique ou de neuropathies du système nerveux autonome, comprenant l'administration d'un inhibiteur de cGMP PDE5 tel que le sildenafil. Cette méthode convient particulièrement pour les patients souffrant d'un ulcère diabétique du pied, d'un syndrome de Raynaud, d'un syndrome Crest, d'une érythromatose, de maladies rhumatoïdes, de rétinopathies diabétiques et d'onychomycoses. L'invention concerne également l'administration d'un inhibiteur de cGMP PDE5 en tant qu'agent de prévention à des patients présentant une prédisposition à une maladie vasculaire périphérique, une neuropathie périphérique ou une neuropathie du système nerveux autonome.
