Viagra Super Active
Viagra Super Active is the most advanced form of Viagra. It contains the active ingredient sildenafil and is used to treat erectile dysfunction in men.
Indications for use
The drug is used to treat erectile dysfunction, characterized by an inability to achieve or maintain an erection of the penis sufficient for satisfactory intercourse. The drug is effective only with sexual stimulation.
How does it work?
Sildenafil restores decreased erectile function by increasing blood flow to the penis. The mechanism of action is based on the release of nitric oxide in the corpora cavernosa at the time of sexual arousal. Free nitric oxide activates the enzyme guanylate cyclase, stimulating an increase in cGMP levels, which causes relaxation of the smooth muscle fibers of the corpora cavernosa and increased blood flow.
How to take Viagra Super Active?
The drug is taken orally.
The recommended dose for most adult patients is 50 mg approximately 1 hour before sexual activity. Taking into account the efficacy and tolerability, the dose can be increased to 100 mg or reduced to 25 mg. The maximum recommended dose is 100 mg. The maximum recommended frequency of use is 1 time / day.
