Coronary artery disease (CAD) is a common condition that is characterised by hardening of the arteries. When a patient has CAD, cholesterol and other substances accumulate on the walls of blood vessels. This can cause them to become narrower which makes it harder for blood to flow through them and reach the penis.
Healthy blood supply is essential for erections as this is what gives the penis rigidity. Reduced blood flow is by far the most common cause of erectile dysfunction (ED). Sildenafil UK approved tablets can, however, effectively treat this condition by improving blood flow. This medicine is a PDE5 inhibitor that works in response to sexual stimulation.
Understanding how it functions in the body
Phosphodiesterase 5, or PDE5, is a naturally-occurring enzyme that regulates blood flow. It is found in various tissues including blood vessels of the penis. PDE5 causes levels of another enzyme called cGMP to decrease, thereby reducing the body’s ability to produce nitric oxide. Nitric oxide causes blood vessels to dilate which enhances blood flow to the penis. By blocking PDE5, sildenafil UK certified tabletsboostlevels of nitric oxidewhich restores erectile function.
The unplanned discovery of Viagra
The discovery that this medicine can improve erectile function was an unplanned event. Sildenafil was originally developed to treat heart conditions like high blood pressure and angina. During early clinical studies in the 1990’s, patients were given varying doses of the medicine to test its efficacy for treating heart conditions. Interestingly, erections were noted as a side effect. The researchers realised that sildenafil could provide an excellent on-demand treatment for ED.
Unbranded sildenafil is cheaper than Viagra
The FDA approved sildenafil in 1998 and since then, it has successfully treated more men with ED than any other medicine. This is often enough encouragement for men to try sildenafil UK approved tablets over other treatments. Fifteen years after it was officially approved the patent for Viagra expired. Viagra is the brand name that was used for sildenafil when the medicine was launched.
Now that the patent has ended, other manufacturers are able to produce this medicine at a cheaper, more competitive price. It is simply known as sildenafil and offers the same safety and effects as Viagra. It is cheaper because generic manufacturers did not need to invest substantial amounts of money to invent sildenafil.
Therefore, they can afford to offer sildenafil UK generic medication to the market at a lower price. Competition among companies causes the price of sildenafil to decrease even further.
