Type of medicine Phosphodiesterase type-5 inhibitor
Used for Erectile dysfunction in adult men
Available as Tablets

Erectile dysfunction (occasionally referred to as impotence) is the inability to obtain or maintain a proper erection. There are several possible causes, the most common of which is a constriction of the arteries that supply blood to the penis.

Sildenafil works by inhibiting the action of a chemical called phosphodiesterase type-5 in your body. This aids in the dilation (relaxation) of blood vessels and increases blood flow to the penis following sexual stimulation. This aids in the maintenance of an erection.

Sildenafil is a prescription medication. While non-branded (generic) sildenafil tablets are available on the NHS, the brand Viagra® is only available to men with erectile dysfunction caused by certain medical conditions.

Sildenafil can also be purchased over the counter in certain circumstances from pharmacies. Consult your pharmacist to determine whether this is a viable option for you.

Another brand of sildenafil tablets called Revatio® is used to treat a completely different condition called pulmonary arterial hypertension; if you have been prescribed this brand of sildenafil tablets, please refer to the separate medicine leaflet called Sildenafil for pulmonary hypertension.

how sildenafil works

Sildenafil Citrate is part of the class of drugs called PDE-5 inhibitors. Sildenafil Citrate increases penis blood flow in response to sexual stimulation. This is done by inhibiting the enzyme that is responsible for the breakdown of the cGMP. CGMP is a chemical that relaxes and expands blood vessels as well as muscles. This lets men keep an erection that is strong enough to allow sexual intimacy.

Sildenafil Citrate only works in conjunction with sexual stimulation. It is effective for 30 to 60 minutes and can be taken as long as 4 hours prior to sexual activity.

Sildenafil Citrate is used to treat erectile dysfunction (ED) and also to lower blood pressure in patients with pulmonary arterial hypertension (PAH). It is prescribed when it is needed to treat ED, and regularly to treat PAH. The stomach, headache, and flushing are the most common negative side consequences.

Sildaforce 100 mg could alter the way other medications perform, and different medicines can affect the way Cenforce 100mg functions, leading to negative side negative effects. Cenforce 100mg cannot provide protection to your partner or you from contracting sexually transmitted infections like HIV. HIV is the virus that is the cause of AIDS.
