The Effects Of Cialis
Being an active substance, Cialis affects certain mechanisms of male body, resulting in erection. But apart from causing erection, Cialis can also produce some effects with other functions of the body. And here's an overview of the functions affected and the effects of using Cialis.
Cialis and vision - Single doses of phosphodiesterase inhibitors are known to cause a certain impairment of color discrimination (especially with blue/green hues). The same effects were observed during PDE6 inhibition, an enzyme that is involved in phototransduction process in the retina. A study on the effects of tadalafil (Cialis) on vision, no effects on visual acuity, intraocular pressure, or pupillometry were observed. During the clinical studies of Cialis the number of patients reporting changes in color vision was very small (less than 0.1% of all patients).
Cialis and blood pressure - Cialis taken by healthy male patients resulted with no significant changes in supine systolic and diastolic blood pressure as well as in standing systolic and diastolic blood pressure. The heart rate was also unaffected by Cialis.
Cialis and blood pressure when taking nitrates - during numerous clinical studies tadalafil (Cialis) regardless of its dosage was observed to significantly increase the hypotensive effects of nitrates. Because of that patients should avoid taking Cialis and nitrates together, because it may result in a dangerous increase of blood pressure that can even be fatal.
Cialis and sperm characteristics - the clinical studies have shown that Cialis (regardless of dosage) had no effects on sperm count, concentration, motility, or morphology over a long period of time. In addition, Cialis didn't affect serum levels of testosterone, luteinizing hormone, or follicle stimulating hormone.
Cialis Effects on cardiac electrophysiology - a single 100mg dose of Cialis (5 times exceeding the normal dose) has produced a change in heart beats. But the change was insignificant, of only 3.1 beats per minute after taking the increased dose of Cialis.
