Active ingredient Avanafil is contraindicated in the following cases:
Patients who have loss of vision in one eye because of non-arteritic anterior ischemic optic neuropathy (NAION), regardless of whether this episode was in connection or not with previous PDE5 inhibitor exposure.
Co-administration of avanafil with potent CYP3A4 inhibitors (including ketoconazole, ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir and telithromycin) is contraindicated.
Avanafil is contraindicated in patients with severe renal impairment (creatinine clearance <30 mL/min).
Avanafil is contraindicated in patients with severe hepatic impairment (Child Pugh class C).
Patients who are using any form of organic nitrate or nitric oxide donors (such as amyl nitrite).
Avanafil was shown to augment the hypotensive effects of nitrates compared to placebo in healthy subjects. This is thought to result from the combined effects of nitrates and avanafil on the nitric oxide/cGMP pathway. Therefore, administration of avanafil to patients who are using any form of organic nitrate or nitric oxide donor (such as amyl nitrite) is contraindicated. In a patient who has taken avanafil within 12 hours, where nitrate administration is deemed medically necessary in a lifethreatening situation, the likelihood of a significant and potentially dangerous drop in blood pressure is increased. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate haemodynamic monitoring.
The co-administration of type 5 phosphodiesterase (PDE5) inhibitors, including avanafil, with guanylate cyclase stimulators, such as riociguat is contraindicated as it may potentially lead to symptomatic hypotension.
Physicians should consider the potential cardiac risk of sexual activity in patients with pre-existing cardiovascular disease before prescribing avanafil.
The use of avanafil is contraindicated in:
Patients with known hereditary degenerative retinal disorders.
