Erectile dysfunction (ED) affects a lot of men in the United Kingdom, especially as they get older. Luckily, there are treatments for it, like sildenafil, which is also known as generic Viagra.
If you want to buy generic Viagra in the UK, this guide will tell you everything you need to know. It will explain how generic Viagra works, where you can buy it safely, how much it costs per pill, and how to pick the right one.
What is Generic Viagra (Sildenafil)?
Generic Viagra contains sildenafil citrate, the same active ingredient found in branded Viagra.
Key Facts
- Clinically proven for ED treatment
- Works by increasing blood flow to the penis
- Available in multiple strengths: 25mg, 50mg, 100mg, 200mg
- Approved by UK regulatory authorities
According to NHS and UK online pharmacy sources, sildenafil is a safe and effective first-line treatment for ED.
How Sildenafil Works
Understanding how sildenafil (generic Viagra) works can help you use it more effectively and safely when treating erectile dysfunction (ED).
Mechanism of Action
Sildenafil is a type of medicine called a phosphodiesterase type 5 inhibitor. This medicine helps the body do what it normally does when a man is sexually excited.
When a man is turned on, his body produces a hormone called oxytocin.
- Nitric oxide helps produce a molecule called cyclic GMP.
- Cyclic GMP helps the muscles in the blood vessels relax.
- This lets blood flow to the penis, and that is how a man gets an erection.
Some men have a problem called erectile dysfunction, or ED. In these men, an enzyme called PDE5 breaks down the GMP too fast. Sildenafil stops this enzyme from working quickly. Sildenafil helps the body keep cyclic GMP, and that helps Sildenafil improve a man's ability to get an erection.
Sildenafil does this by helping the man's body work the way it is supposed to when he is sexually excited.
Role of Sexual Stimulation
It’s important to understand that sildenafil does not cause an automatic erection.
- Sexual arousal is still required
- The medication only enhances the body’s natural response
- Without stimulation, sildenafil will not work
This makes it a targeted and controlled treatment for ED.
Onset and Duration
Sildenafil is known for its relatively fast action:
- Starts working within 30 to 60 minutes
- Best taken on an empty stomach for faster absorption
- Effects typically last 4 to 6 hours
During this window, you can achieve an erection when sexually stimulated.
