Viagra (sildenafil) belongs to a class of medications, known as phosphodiesterase inhibitors, which are indicated for the treatment of erectile dysfunction in men. Other phosphodiesterase inhibitors include Levitra (vardenafil) and Cialis (tadalafil). These medications are not necessarily different types of Viagra, but treatment alternatives. Viagra, commonly referred to as the "little blue pill" was the first erectile dysfunction medication to be approved by the U.S. Food and Drug Administration (FDA). By inhibiting phosphodiesterase, Viagra enhances the effect of nitric oxide allowing for smooth muscle relaxation and increasing blood flow to specific areas of the body in the presence of sexual arousal or stimulation. Viagra exhibits no therapeutic responses in the absence of sexual stimulation. Possible side effects associated with treatment with Viagra include flushed skin, nausea or abdominal pain, congestion in the nose, diarrhea, vision clouded with a blue tint, headache and digestive problems.During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away.

The maximum dose in patients with moderate hepatic impairment should not exceed 10 mg.

Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and corpus cavernosal smooth muscle. This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells. Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum. The inhibition of phosphodiesterase type 5 (PDE5) enhances erectile function by increasing the amount of cGMP. Tadalafil inhibits PDE5. Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 by tadalafil has no effect in the absence of sexual stimulation.

VIAGRA does not protect against sexually transmitted diseases, including HIV.To address that problem, Lieberman has developed a simple paper card that tests whether a drug contains the correct active ingredients. The user scrapes a tablet across the test card, then dips the card into water. Water travels up the card, mixing chemicals with the drug, and a colored bar code shows whether the correct ingredients are present. Lieberman’s cards currently sense 12 substances, including different types of antibiotics and anti-tuberculosis medications, as well as fillers like chalk, flour, and acetaminophen, a common additive since it lowers fevers, making patients believe the medicine is authentic. She’s currently testing the card with pharmacists in Kenya. si toma otros medicamentos para tratar la hipertensión arterial pulmonar, como riociguat (Adempas).
