A detailed overview on viagra

Many people have misunderstandings about Viagra. The reason for these prejudices is that they don’t know much about Viagra. Viagra is a clinical first-line drug that can treat male erectile dysfunction.

The little blue pill was originally developed as a cardiovascular treatment, but researchers found that it did not work as well as expected for cardiovascular disease. However, it did work well for male sexual dysfunction.

But Viagra is not an aphrodisiac, it cannot increase or stimulate sexual desire. After taking Viagra, you can’t just sit there and wait for the drug to take effect. Only when you are fully aroused or stimulated will the penis become engorged and the effect of Viagra be fully exerted. To use a vivid metaphor, the bullets are in the warehouse and the gun is loaded, but you still have to pull the trigger yourself.

There are three common types of Viagra, which one is more effective?

There are many types of Viagra-like drugs, and the more common ones on the market are sildenafil (Viagra), tadalafil (Guan Ai), vardenafil ( Ai Yue Da ), etc. Many male friends are also confuse. These all look good, so how should they choose?

Can they be mix? Here is an analysis of the onset, duration, and drug response of these three drugs. You can choose the matching drug according to your needs.

Onset and duration of action

Sildenafil (Viagra): It usually takes effect about 1 hour after taking it, and the half-life of the drug is 4 hours; the effect can last for 4-6 hours.

Tadalafil (Tadalafil): It usually takes effect about half an hour after taking it, and the half-life of the drug is 18 hours; the drug effect can last up to 36 hours.

Vardenafil (Aiyueda): It usually takes effect about 1-2 hours after taking it, and the half-life of the drug is 4-6 hours; the drug effect can last for 4-8 hours.

The half-life of a drug refers to the time it takes for the blood concentration of a drug in the body to drop by half. Generally speaking, the longer the half-life, the longer the drug lasts.

Adverse Reactions

Common adverse reactions of sildenafil and vardenafil include dizziness, headache, abnormal vision, increased light sensitivity of the eyes; cardiovascular (angina pectoris, myocardial infarction, heart failure, rapid heart rhythm abnormalities, etc.), chest pain, back pain, nausea and vomiting, facial flushing, gastrointestinal reactions, etc.

Tadalafil has significantly reduced adverse reactions in cardiovascular, visual, chest and back pain, and is relatively mild. But there is no need to worry too much, as most of these adverse reactions are mild and short-lived, and can be recover without any treatment.

Food taboos

Usually, when taking Viagra-like drugs, you should try to avoid eating greasy, high-calorie foods before and after taking the drug, and avoid drinking alcohol, so as not to delay the peak time of the drug or affect the direct effect of the drug. Tadalafil is relatively relax in terms of food taboos and is not affect by high-fat diets and drinking. So there is no need to avoid it.

Here we would like to remind everyone that although Viagra-like drugs can be call “good news for men with ED”. If male friends with normal sexual function use such drugs blindly for the purpose of “improving sexual function”, it will cause unnecessary risks to their own health and unhealthy drug dependence, bringing unexpected harm to the body.

Who should not use Viagra?

1. Heart disease patients : people with severe heart disease or who are currently taking nitrate drugs.

2. Patients with hypotension : Viagra may cause a drop in blood pressure and should be use with caution by patients with hypotension.

3. Patients with retinal or optic nerve diseases : Viagra may affect vision and people with related eye diseases should avoid using it.

4. Currently taking specific medications : such as α-receptor antagonists, antihypertensive drugs, etc., which may interact with Viagra.

5. Severe liver and kidney dysfunction : liver and kidney dysfunction may affect drug metabolism and increase the risk of side effects.

Finally, I would like to remind everyone that it is okay to use medication, but using it correctly is the key! It is important to first understand the limitations and potential risks of Viagra-like drugs, which is crucial to ensuring your own health.
