Viagra (sildenafil) is used to treat erectile dysfunction. Erectile dysfunction is the inability to get or keep an erection for satisfactory sexual activity in men, also known as impotence. Sildenafil belongs to a class of medications called phosphodiesterase type5 (PDE5) inhibitors. Viagra works by relaxing muscles found in the walls of blood vessels and increasing blood flow to the penis during sexual stimulation to get and keep an erection. Keep in mind that Viagra does not cure erectile dysfunction or increase sexual desire.
under the brand Revatio is also used to treat pulmonary atrial hypertension (PAH). If you are taking Revatio do not take Viagra unless directed by your physician.
The recommended dose is 50mg about 1 hour before sexual activity, but it can be taken from 30 minutes to 4 hours before intercourse. The maximum daily dosage is once per day, with or without food. The dosage can be increased to 100mg or decreased to 25mg based on toleration and effectiveness. Viagra 100mg are available in KamaHealth.
