Cialis has comfortably the longest effectiveness period of any erectile dysfunction drug on the market.
Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues.
So to answer the above question, no, Viagra would not necessarily give a stronger erection than Cialis, and vice versa. However, Cialis will last longer and can help achieve one or more erections for up to 36 hours. This is considerably longer than Viagra, which is typically effective for 4-6 hours.

It relaxes the smooth muscles and arteries inside the penis. At the same time, it increases blood flow to the penis.

Penile implant. A penile implant involves a 30- to 45-minute surgical procedure that places a water-based device into the erection chambers of the penis, which enables you to reliably control exactly when and how long an erection lasts. Dr. Starke says this is the closest option to a cure that exists for ED.
Common physical causes of erectile dysfunction include heart disease, diabetes, nerve damage and high blood pressure. Hormonal issues, such as low testosterone, can also affect your level of sexual desire, which may stop you from getting an erection even with Viagra.
Cialis works by enhancing the effects of one of the chemicals the body normally releases into the penis during sexual arousal. This allows an increase of blood flow into the penis. An erection is the result of an increase in blood flow into certain internal areas of the penis.
