3 chemical compounds used in erectile dysfunction

People with impotence problems are increasingly seeking help with over-the-counter products. Usually these are dietary supplements or medications that are based on an active substance or a herbal mixture. The preparations belonging to the group of Type 5 phosphodiesterase inhibitors are the most effective substances available on the market.

Preparations containing DHEA - Type 5 phosphodiesterase inhibitors

Introduction of the first generation of phosphodiesterase inhibitors type 5 into clinical practice proved to be a real breakthrough in the treatment of impotence disorders in both men and women. These compounds, due to their chemical properties, participate in the formation of cyclic guanosine monophosphate. As a result, the smooth cavernous muscles contract. This leads to an inflow of blood and an erection. Medicines belonging to this group, however, work only with adequate sexual stimulation. The contraindication for the use of these drugs is the administration of organic nitrates and Peryoni's disease.

The preparation is available in 3 different variants. The product is available in a dosage of 25 mg, 50 mg and 100 mg. The dosage that is appropriate for you is determined by your doctor based on the assessment of the disorder and its intensity. Sildenafil is an active substance that is most often found in dietary supplements or prescription drugs designed to correct erectile dysfunction. Interestingly, studies have shown that the most common side effect of this drug is long-term and strong erection. Sildenafil's pharmaceutical substitutes include..: Zenegra, Penegra, Silagra, Maxigra. Their action is almost the same, the difference is only visible in the price of the product itself. Due to the fact that problems with sexual disorders also affect women, we created a preparation called Lovegra. The product has undergone a delicate modification, adjusted to the female organism.

The drug used in accordance with the manufacturer's or physician's recommendations should not cause any side effects. However, there are such ailments as: headaches and dizziness, nausea, vomiting, diarrhoea, urinary tract infections, temporary vision disorders and palpitations.


Cialis, Tadalis are drugs available in pharmacies that contain the active ingredient tadalafil. The chemical compound is present in four different doses: 2.5 mg, 5 mg, 10 mg, 20 mg.

Tadalafil, however, is distinguished by a much longer operating time. Its maximum blood concentration is 2 hours after admission. More time to be effective is associated with a longer time to attempt sexual intercourse. The study showed that the preparation proved effective in 81% of patients who decided to treat with this chemical compound. The manufacturer recommends using no more than 1 tablet per day.
