Cialis or Viagra which is better?

Sildenafil (Viagra) and Tadalafil (Cialis) are two renowned medications used to treat erectile dysfunction, with only slight differences in their mechanisms of action. Viagra has been on the market for over 15 years, making it a more popular choice among men. However, Cialis, though less known, has several significant advantages worth exploring.

Both drugs belong to the phosphodiesterase inhibitor of the fifth type (PDE-5) group. They work by suppressing an enzyme that constricts the blood vessels of the penis, thereby weakening the erection. Both Cialis and Viagra enhance natural arousal, but it is important to note that they are not aphrodisiacs. Instead, they serve to improve erection and sexual arousal in men.

While the composition of Cialis and Viagra (such as sildenafil, tadalafil, vardenafil, kamagra, suhagra, tadacip, revatio, cenforce) differs slightly, manufacturers of Cialis generics often use cheaper dyes, preservatives, additives, and fillers, such as chalk, talc, and sodium carbonate.

The effects of all PDE-5 blockers are essentially the same, but they differ in onset time and duration. Cialis is excreted more slowly than Viagra, providing a longer-lasting effect. Additionally, both drugs affect other enzymes besides the targeted PDE-5 enzyme. For example, Viagra activates the PDE-6 enzyme, responsible for color perception, while Cialis inhibits the activity of PDE-11 in the heart, thymus, and brain. The potential undesirable side effects of Cialis's PDE-11 inhibition are not yet fully understood.

Cialis is renowned for its extended action, providing an erection for up to 36 hours, compared to Viagra's maximum 5-hour window. According to consumer reviews, Cialis also has fewer side effects than Viagra.

Upon ingestion, Cialis induces sexual arousal within half an hour, while Viagra takes 45-60 minutes to take effect. Moreover, Cialis is generally cheaper than Viagra, which is considered the original medication from a European manufacturer.

Another interesting aspect to consider is the interaction of these medications with food and alcohol. Viagra acts faster on an empty stomach, and certain food combinations can lead to complications, such as liver pain. In contrast, Cialis is not affected by meal schedules. As for alcohol, Cialis advertising claims no interaction, unlike Viagra and other competitors. However, it is essential to consume alcohol responsibly and in moderation when using either medication.
