How Does Viagra Work? | What Does Viagra Do?
Viagra is working by increasing blood flow that is going to the penis and this is helping a man to get and to maintain an erection.
Make sure you know that this medication is not going to protect against STD (Sexually Transmitted Diseases) like for example HIV, syphilis, hepatitis and others. Also, is important to know that if there is no sexual stimulation, the product won’t work and that’s because this product is increasing the blood flow and won’t offer sexual stimulation. If there’s not sexual stimulation – there’s no blood flow going to the penis and the product won’t work by increase the blood flow.
Sildenafil is working by inhibiting the phosphodiesterase type 5 (PDE5) enzyme. This is the enzyme that is degrading the number of cGMP (cyclic Guanosine Monophosphate). This is responsible for relaxing the smooth tissue allowing for more blood flow. When the individual is having too much PDE5 enzyme, too much cGMP is blocked so the individual cannot get the erection or maintain it.
By taking Sildenafil – you are inhibiting PDE 5 and this causes the erection and allows you to keep it during sexual intercourse.
How Long Does Viagra Last? | Sildenafil 20 mg How Long Does it Last?
This is the moment when the biggest difference between Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) is noticed. All the 3 types of medications are working the same way – inhibiting PDE5 enzyme, but each of them lasts different times. For example, Viagra is considered to last the shortest period of time compared to the 3.
It has a half life of about 3-4 hours and that’s why the product is considered effective for only approximately 6 hours. How much would Viagra last depends on a number of factors such as: is it taken with food or not, is the individual having underlying health issues and others.
For example, if a person has some specific health issues, this may increase or decrease the time that Viagra is effective. Also, taking Viagra on a full stomach would make it less effective and make it work less time. Taking it on an empty stomach – Sildenafil is working longer and considered more effective.
However, in normal circumstances, Viagra – Sildenafil (SP Agra) is considered effective for about 6 hours.
How Long Does it Take for Sildenafil to Take Effect?
Viagra might be taken by mouth or under the tongue. Nonetheless, by far the most used method is taken by mouth. This specific product – SP Agra is also coming in form of tablets. When taken for erectile dysfunction then the average time for onset of erection is ranging anywhere between 12 to 70 minutes for different men.
In normal circumstances, Viagra is taking approximately 20-30 minutes to take effective. Taking in consideration that it requires a fairly short time for taking effect and is having a fairly short half life, the product should be taken as needed (before sexual intercourse).
Viagra Administration | Sildenafil Dosage
Viagra is a product that should be taken as needed – as it was mentioned earlier. This product is also treating other health conditions but in nearly all cases is given for erectile dysfunction. With this being said, the dosage of Sildenafil (Viagra) greatly depends on a number of factors such as – personal health, how bad is the ED condition, why exactly you need to use it and other factors.
We recommend not to take a dosage more than once every 24 hours. Also, we recommend to start slowly and then increase the dosage if needed (if no results are seen).
Doses usually range anywhere between 20 mg to 150 mg and rare when higher. Usually, elder people require more, but this also comes with possible side effects. Most people find their perfect dose between 50 mg to 100 mg.
