Cialis or Viagra which is better?
Sildenafil (Viagra) and Tadalafil (Cialis) are two well-known remedies for erectile dysfunction, the mechanism of action of which is only slightly different from each other. However, Viagra is more popular. It is not surprising, as this drug has been in the pharmaceutical market for already more than 15 years.
Meanwhile, manufacturers of each drug claim that it is better than others. Cialis, which is less known to the male population compared to Viagra, is not only less efficient than Viagra, but also has several significant advantages, which will be discussed below.
Both drugs belong to the group of phosphodiesterase inhibitors of the fifth type (PDE-5). An enzyme suppresses the expansion of the blood vessels of the penis, and, therefore, weakens an erection. The principle of Cialis is based on increasing natural arousal. It should be remembered that the drug is not an aphrodisiac, but only enhances the erection and sexual arousal of a man. The principle of action of Viagra is similar.
However, the composition of Cialis and Viagra is somewhat different. Manufacturers of Cialis generics often use cheaper dyes, preservatives, additives, and fillers, among which are chalk, talc, and sodium carbonate.
Although the effect of all PDE-5 blockers is exactly the same, it differs in the time of onset and the timing of the action. Cialis is excreted more slowly. Both drugs, in addition to the “necessary” PDE-5 enzyme, block the other enzymes. For instance, Viagra activates the PDE-6 enzyme, which is responsible for color perception. While Cialis inhibits the activity of PDE-11 in the heart, thymus, and brain. However, it has not yet clear what undesirable after-effects this may lead to.
Cialis is famous for its longer action. While the well-known Viagra gives effect for a maximum of 5 hours, the modern drug allows a man to feel an erection for 36 hours. According to consumer reviews, Cialis, compared with Viagra, has fewer side effects.
After taking Cialis pills, sexual arousal occurs within half an hour. Viagra gives effect only in 45-60 minutes. In addition, Cialis is cheaper than Viagra, which is considered to be the original medicine from a European manufacturer.
Another interesting aspect is the interaction of these medications with food products and alcohol. It is known that Viagra acts much faster on an empty stomach than when eating. Moreover, while the meal schedule does not affect the time of use of the Cialis, it is not true about Viagra as in this case the combination with some products can result in complications, such as pain in the liver region. However, the effect still comes. As for alcohol, Cialis, as stated in advertising brochures, does not interact with it, unlike Viagra and other competitors.
