Sildenafil is also known as Viagra™. This is a common medication prescribed by doctors to men who suffer from erectile dysfunction (impotence) and pulmonary arterial hypertension. On this page I will focus on how viagra sverige works to treat erectile dysfunction.
More than 150 million men suffer from impotence worldwide. This condition usually causes stress, anxiety and strain in marriages. Sidenafil and other medications like Cialis™, Levitra™, yohimbine and trazodone are used by men to achieve an erection.
Erectile dysfunction is defined as inability to achieve or maintain an erection for sexual intercourse for at least 3 months. Learn more about erectile dysfunction here.
How does sildenafil work?
High blood flow to the penis is required to achieve and maintain an erection. Blood flow to the penis is reduced in impotence due to many causes like atherosclerosis. Nitric oxide is a hormone required in the process of having an erection. Nitric oxide will activate an enzyme causing the production of a substance called cyclic guanosine monophosphate (cGMP). This substance cGMP causes arteries to dilate (sinusoidal smooth muscle relaxation) and this will increase blood flow to the penis.
An enzyme called phosphodiesterase-5 (PDE5) destroys the cGMP required to achieve an erection. Sidenafil will inhibit the enzyme phosphodiesterase-5 (PDE5) and this leads to a longer lasting erection.
How to take sildenafil
Sidenafil usually comes in tablet forms (25, 50 and 100mg). Use it as prescribed by your doctor. A maximum is one tablet a day is usually enough and safe for you. Take one tablet at least 30 minutes before sexual activity though 1 hour will achieve good results. The effects may last for 4 hours.
