Either increases effects of the other by additive vasodilation.
Coadministration of PDE-5 inhibitors (eg, avanafil, sildenafil, tadalafil, vardenafil) and guanylate cyclase stimulators (eg, riociguat) is contraindicated due to risk of additive hypotension; do not administer 24 hr before or within 48hr of each other. Either increases effects of the other by pharmacodynamic synergism. Coadministration of vericiguat with PDE-5 inhibitors may result in additive hypotensive effects. apalutamideapalutamide will decrease the level or effect of tadalafil by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Coadministration of apalutamide, a strong CYP3A4 inducer, with drugs that are CYP3A4 substrates can result in lower exposure to these medications. Archived from the original on 22 April 2018.
