Viagra vs Levitra and Cialis

The introduction of Cialis and Levitra considerably decreased the marketing share of sildenafil citrate in the year 2003. If sildenafil citrate is not beneficial in the treatment of erectile dysfunction, Cialis and Levitra can be a good choice of drug, and the mechanism of action is similar to sildenafil citrate.

VIAGRA vs LEVITRA

Levitra (Vardenafil) is a PDE-5 inhibitor drug prescribed for erectile dysfunction and other problems in male impotence. The plasma half-life of Levitra is 3-4 hours, and thereafter the drug activity will be decreased in blood.

LEVITRA received the Food and Drug Administration’s approval in 2003.

The significant features in LEVITRA are as following:

  • Levitra can be used with alcohol and meal without causing severe side effects or decreasing effects
  • The drug effects can remain up to 12 hours which is twice more than in VIAGRA
  • Levitra is reported to prolong duration of sexual intercouse (not approved for the premature ejacuation)
  • Levitra starts to act in 20 minutes after intake
  • LEVITRA has a more tolerable safety profile with less side effects compared to VIAGRA
  • Vardenafil, an active ingredient in LEVITRA, has an FDA-approved orally disintegrating formulation (brand name: STAXYN).

VIAGRA VS CIALIS

CIALIS is a brand name for tadalafil, a PDE-5 inhibitor, that is prescribed for male sexual dysfunction.

The significant features in CIALIS are as following:

  • Unlike of sildenafil citrate, the plasma half-life of Cialis is about 17.5 hours, therefore CIALIS effects can remain up to 36 hours (this is why CIALIS is often called the Weekend Pill).
  • Additionally, low dosaged CIALIS (2.5 mg and 5 mg) can be used on a daily basis for the male to be ready to a spontaneous sexual activity.
