[Efficacy and tolerance of intracavernous injection of moxisylyte in patients with erectile dysfunction: double-blind placebo-controlled study].
OBJECTIVE
To evaluate the efficacy of intracavernous moxisylyle versus placebo in patients with erectile dysfunction of various origins. To assess the local tolerance and systemic safety of moxisylyte by self-administered injection.


METHODS
Multicentre study, comprising two treatment phases: The first, double-blind phase, was conducted in two parallel groups of randomized patients, over a 1-month period (1 injection per week) in the investigator's office; the second phase was conducted under open conditions in the patient's home, over a period of 3 to 11 months. Self-administered injections (1 to 2 per week) were performed using a prefilled syringe containing 10 mg of moxisylyte.


RESULTS
Out of 307 patients evaluated during the first phase, the qualitative and quantitative superiority of erectile response induced by moxisylyte compared to placebo was confirmed (p < 0.0001). The stability of the response to moxisylyte was also confirmed on 4 injections, and the frequency of responses compatible with sexual intercourse ranged from 48% to 52% from one injection to another. This efficacy was also maintained during the open phase, as 92% of the 4,487 self-administered injections generated positive erectile responses. The quality of these responses was considered sufficient to allow sexual intercourse after 62% of injections. The local tolerance was considered to be excellent for more than 95% of injections, without any major adverse effects, and a very low risk of prolonged erection and fibrotic reaction. The systemic safety was also considered to be excellent for more than 98% of erections.


CONCLUSIONS
This study confirms the possibility of obtaining an erectile response by intracavernous injection of 10 mg of moxisylyte with a very low incidence of local and systemic adverse effects. It also tends to confirm the superior efficacy of moxisylyte by self-administered injections at home than by injection in the doctor's office.
