In clinical pharmacology studies, Cialis was shown to potentiate the hypotensive effect of nitrates.

It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors. Physicians should discuss with patients the increased risk of NAION in individuals who have already experienced NAION in one eye. Physicians should also discuss with patients the increased risk of NAION among the general population in patients with a "crowded" optic disc, although evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including Cialis, for this uncommon condition [see Warnings and Precautions (5.4) and Adverse Reactions (6.2)]. cheap cialis Who Should Not Take Cialis?Dyspepsia 1% 4% 8% 10%Cialis stays active in the body much longer than the other drugs.
