Viagra Action
Viagra treats erectile dys function and works by relaxing muscles and increases blood flow to particular areas of the body (in this case, the penis, specifically). Its effects last up to four hours. The most common side effects of Viagra are headache, facial flushing, and upset stomach. Rarely, blurred vision, or sensitivity to light may briefly occur.
As well as treating impotence, Sildenafil Citrate can also be effective in treating Pulmonary Arterial Hypertension (PAH). Similarly to how it acts to relax muscles of the penis, it relaxes arterial walls; therefore, reducing resistance and pressure in the arteries.
Sildenafil Citrate is solely active in relaxing muscles and increasing blood flow to the heart, lungs and penis due to PDE-5, yet vasodilation is not increased in other parts of the body.

The onset of action is fast, and results are seen within 15 to 30 minutes. Side effects are small, but due to individual differences, less than 2% of people still experience mild headaches. Soluble in water and ethanol, it is an ideal raw material for making aphrodisiac wine, soft capsules and oral liquid. The duration can reach more than 6 hours, and the launch of vardenafil makes the current international advanced aphrodisiac raw materials into three: Sildenafil (sildenafil, brand name: Viagra), Tadalafl (tadalafil, brand name: Cialis cialis), Vardenafil (vardenafil, brand name: Alida). Vardenafil was approved by the US FDA in August 2003 in the United States and the European Union. Vardenafil is completely soluble in water and ethanol, making it the most ideal and preferred raw material for manufacturers of health aphrodisiacs, oral liquids, drinking agents and soft capsules: in addition, the least used, the fastest onset time, and high safety have also been favored by other manufacturers of high-end aphrodisiac products. After a large number of clinical studies, Valdenafil (Vardenafil) has shown that as a new generation of phosphodiesterase 5 (PDE5) inhibitors, vardenafil hydrochloride (Levita) has the characteristics of potency, high selection and good tolerability, and its emergence has brought new options for the treatment of erectile dysfunction (ED).
