Sildenafil is a phosphodiesterase type 5 inhibitor. Sildenafil belongs to a class of drugs known as PDE5 inhibitors. The action of sildenafil, as an inhibitor of the cyclic GMP-kinase enzyme system, is dependent on the presence of magnesium in the blood. In healthy subjects, the blood level of sildenafil is approximately 18.6 mmol/L. Sildenafil enhances the effect of nitric oxide on smooth muscle relaxation in the pulmonary vascular smooth muscle. Relaxation of pulmonary vascular smooth muscle is due to the inhibition of the enzyme phosphodiesterase type-5 (PDE5).
DosageThe recommended dosage of sildenafil for erectile dysfunction is between 50 and 100 mg (20 to 80 mg) taken orally once or twice a day. The maximum recommended dosage is 100 mg to be taken with food.
EffectsEffects of sildenafil in the human body have not been clearly defined.
InteractionsThere are, in the case of sildenafil, other medicines or herbal products with the action of sildenafil. Therefore, the presence of sildenafil can interact with the blood pressure lowering medicinal product, which may lead to hypotension.
CautionThere are, in the case of sildenafil, other blood pressure lowering medicinal products or herbal products with the action of sildenafil. The administration of sildenafil and other blood pressure lowering medicinal products with the blood pressure lowering medicinal products, which have the blood pressure lowering medicinal product, may, in the course of the interaction, increase the hypotensive effect of sildenafil. If the blood pressure lowering medicinal product, which has the blood pressure lowering medicinal product, is administered with the sildenafil blood pressure lowering medicinal product, it may cause a lowering of the blood pressure.
In the case of sildenafil, there are some preparations of sildenafil, which have the action of sildenafil. Therefore, it is recommended that sildenafil be taken under the supervision of a doctor and in accordance with the instructions provided on the package.
Mode of ActionSildenafil, when used in adequate doses, inhibits the activity of a number of phosphodiesterase (PDE) 5 enzyme systems. The inhibition of PDE5 results from the direct interaction of sildenafil and its co-substrate, cGMP. The inhibition of PDE5 by sildenafil results from the inhibition of the phosphodiesterase type-5 enzyme by the co-substrate of the enzyme PDE-5. Inhibition of PDE-5 by sildenafil results from the phosphodiesterase type-5 enzyme, which is located in the smooth muscle cells of the corpus cavernosum, the corpus cavernosum of the pulmonary artery, the pulmonary arterioles, the pulmonary vascular smooth muscle cells of the pulmonary arterial bed, and the corpus cavernosum of the cardiac muscle.
Sildenafil, when taken orally, increases the level of cGMP in the smooth muscle cells of the corpus cavernosum, the corpus cavernosum of the corpus cavernosum of the pulmonary artery, the pulmonary arterioles, the pulmonary vascular smooth muscle cells of the pulmonary arterial bed, and the corpus cavernosum of the cardiac muscle. The inhibition of cGMP by sildenafil increases the level of the phosphodiesterase type-5 enzyme by approximately 80% and the degree of inhibition by sildenafil by approximately 60%. The increased level of cGMP by sildenafil may lead to vasodilation in the pulmonary arteries and may also lead to relaxation of the smooth muscle cells of the corpus cavernosum of the corpus cavernosum, the corpus cavernosum of the pulmonary artery, the pulmonary arterioles, the pulmonary vascular smooth muscle cells of the pulmonary arterial bed, and the corpus cavernosum of the cardiac muscle.
When sildenafil is taken in sufficient amounts, the level of cGMP in the smooth muscle cells of the corpus cavernosum, the corpus cavernosum of the corpus cavernosum of the corpus cavernosum of the pulmonary artery, the pulmonary arterioles, the pulmonary vascular smooth muscle cells of the pulmonary arterial bed, and the corpus cavernosum of the cardiac muscle should be evaluated.
The cheapest erectile dysfunction (ED) pills are generic Viagra, called.
The term "generic" refers to the active ingredient of a medicine or drug rather than to the advertised brand name under which the medicine is sold. It is a term referring to any drug marketed under its chemical name without advertising.

What is Viagra (sildenafil)Viagra is a FDA approved medication recommended for the treatment of erectile dysfunction. It works by blocking the reuptake of blood in the kidney and the liver. This allows the chemicals in blood-sucking erectile dysfunction medications called phosphodiesterase type 5 (PDE5) inhibitors to overcome the inability to achieve and maintain an erection during sexual stimulation. This medication works by preventing the breakdown of phosphodiesterase type 5 (PDE5), an enzyme that breaks down certain chemicals in the body. This medication is an effective way to manage erectile dysfunction and is particularly beneficial for patients who have difficulty achieving or maintaining an erection during arousal.
