Avana 100 mg medicines are prescribed for men diagnosed with erectile dysfunction or impotence condition. These high-dose medicines help improve the erection function by boosting the production and release of nitric oxide in the penile blood vessels. Nitric oxide is a powerful component that manages constriction, causes vasodilation, and augments an abundant blood flow to the penile shaft by overcoming all the blockages of the penile blood vessels. The pill must be taken about an hour before the planned sex. The medicine is not responsible for triggering erections spontaneously. It yields the required outcome only in the presence of sexual stimulation.
