Pharmacy and Medicine

Sex happiness is essential for all individuals, regardless of the age. But, erection problems still bring about agitation for a few men, give them no piece and lower their self-esteem. And any man, no doubt, wants to be at his best in sex. Frequently it is erectile dysfunction that leads to the aggravation and even rupture of relationships.

Three drugs curing erectile dysfunction - Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) - are almost identical with respect to pharmaceutics. Meantime producers of every drug try to persuade the audience that it's better than others. The success of advertising drives rather than medical parameters are probable to determine the destiny of every drug preparation and determine the most prevailing of them. There is no problem to buy Viagra online in various web-shops. You may also buy Cialis online there.

All three drug preparations are the part of the group of phosphodiesterase type 5 inhibitors. Erection is usually weakened by PDE-5, the enzyme that holds back the stretching of veins of the phallus. Viagra and Levitra are quite identical in organization and qualities, and the composition of Cialis is somewhat different.

But Levitra is fast absorbed and Cialis is slowly driven out of the organism, and that's the principle difference between the drug preparations in fact. That's all FDE-5 inhibitors have nearly similar impact. They differ in term and duration of action.

All three drugs are effectual in approximately 80 percent of cases.

But Levitra produces an impact in quite small dosage - 5-10 times smaller than those of the opponents. The strength of ill-effects can be slightly decreased because of this. But the drug is still contraindicative with disorders of cardiovascular system and after the stroke.

There is still more on under-effects: all three medicines block not only the “needed” FDE-5 enzyme but also the others. E.g., Viagra and Levitra produce an influence on the FDE-6 ferment, which is answerable for color sense. The brain, heart, or thymus are regulated by FDE-11, the action of which may be held back by Cialis. But no one has yet found out what exact inappropriate consequences it may bring about.

Another important aspect is the interplay of these medicaments with nourishment and alcohol drinks. It's well known that taken on an empty belly Viagra produces a much faster impact than with a meal. However, although slowly the impact still occurs at any rate. The advertising prospectuses of Cialis guarantee that it does not interact with alcohol, as opposed to the rivals. In fact, there is information about Levitra being also safe in conjunction with alcohol drinks. But marketeers take their time to bring this “trump” and convince all to buy Levitra. It's obvious that the “trump” is doubtful: 1 of the widespread reasons of erectile dysfunction is drink abuse.
