Indications

Treatment of erectile dysfunction characterized by an inability to achieve or maintain an erection of the penis sufficient for satisfactory intercourse.

Special instructions

Sexual activity has a potential risk for patients with cardiovascular diseases, therefore, treatment of erectile dysfunction, including the use of udenafil, should not be performed in men with heart diseases in which sexual activity is not recommended.

Patients with difficulty in outflow of blood from the left ventricle (aortic stenosis) may be more sensitive to the action of vasodilators, including PDE inhibitors. Despite the absence in the course of clinical studies of cases of prolonged erection (more than 4 hours) and priapism (painful erection, lasting more than 6 hours), such phenomena are characteristic of this class of drugs.

In the event of an erection lasting more than 4 hours (regardless of pain), patients should immediately seek medical help. In the absence of timely treatment, priapism can lead to irreversible damage to erectile tissue and erectile function.

Due to the lack of clinical data on the use of udenafil in patients older than 71 years of age, this drug is not recommended. Udenafil is not recommended in combination with other treatments for erectile dysfunction.

Side effects

Side effects observed during clinical trials of udenafil, depending on the frequency of their occurrence: very often -? 10% of cases often - 1-10% sometimes - 0.1-1%.

Drug Interactions

CYP3A4 cytochrome P450 isoenzyme inhibitors (ketoconazole, itraconazole, ritonavir, indinavir, cimetidine, erythromycin, grapefruit juice) may enhance the effect of udenafil.

Ketoconazole (at a dose of 400 mg) increases the bioavailability and Cmax of Udenafil (at a dose of 100 mg) almost twice (212%) and 0.8 times (85%), respectively. Ritonavir and indinavir significantly enhance the effect of udenafil. Dexamethasone, rifampin and anticonvulsants (carbamazepine, phenytoin and phenobarbital) can accelerate the metabolism of udenafil, so co-administration with the above drugs weakens the effect of udenafil.

Co-administration of udenafil (30 mg / kg, oral) and nitroglycerin (2.5 mg / kg once intravenously) did not show any effect on the pharmacokinetics of udenafil in experimental studies, however, the simultaneous use of nitroglycerin and udenafil is not recommended due to a possible decrease blood pressure.

Udenafil and drugs from the group of alpha-blockers are vasodilating agents, therefore, when taken together, they should be prescribed in minimal doses.

Overdose

With a single 400 mg dose, the undesirable effects were comparable to those seen when taking udenafil at lower doses, but were more common.

Treatment: symptomatic. Dialysis does not accelerate the elimination of udenafil.
