Sildenafil Citrate: various forms and its online purchasingSildenafil citrate is the drug name of the active ingredient present in Viagra, a famous erectile dysfunction medication. When sildenafil citrate is sold in 25, 50, or 100 mg dosages, it is called as Viagra or it is the generic for it. When it is vended in a 20 mg dosage, it is called Revatio or the generic for Revatio.
Revatio is rather FDA approved for treating pulmonary hypertension. Viagra and Revatio both contain the exact same chemical (i.e., sildenafil citrate), and it simply differs in the strength in which it is produced.
Physicians have the discretion to prescribe 20 mg sildenafil citrate pill for ED in doses ranging from 20 mg to 100 mg if they understand that it is an appropriate course of treatment for any particular patient. A 20 mg tablet for ED is an off-label usage of the medicine. It is up to the medical judgment of a physician to decide if any off-label treatment is appropriate for a patient depending on symptoms, his unique medical history, and preferences.
How does sildenafil citrate work?
1. In order to understand how sildenafil citrate works to treat ED, it is important to first understand how erections work.
2. cGMP causes the corpora cavernosa to relax. This allows blood to rush into the Cavernosal arteries.
3. The blood rushes into the penis, during that the veins that drain blood from the penis get compressed resulting in the increased blood to be trapped inside the penis causing an erection.
4. An enzyme named as phosphodiesterase-5 (PDE-5) breaks down cGMP and this leads the penis to return to its flaccid state.
5. PDE5 inhibitors (PDE5i) block this enzyme, leading to higher levels of cGMP and improves the ability to obtain and maintain an erection.
Common Side Effects of sildenafil citrate
The most common side effects of sildenafil citrate include headaches, stuffy nose, facial flushing, and upset stomach. Whereas serious side effects that are rare include an erection that will not resolve after 3–4 hours (or priapism), sudden hearing loss, and sudden vision loss in one or both eyes.
What Happens on Overdose?
Taking more than the recommended amount of sildenafil citrate greatly increases risk of side effects, including most severe ones that can be dangerous, like severe low blood pressure or priapism. Thus, never take more than the prescribed amount. If you find any severe side effects seek out emergency medical attention immediately.
Is Buying sildenafil citrate pill Online Safe?
Buying this pill online can have risks only when the source is not reputable. Counterfeit PDE5i can have variable quantities of the active drug ranging from 0%–200+% of the drug. If the active ingredient is in lower amounts than expected, then it leads to lack of effectiveness. If active drug is in higher amounts, it may result in higher potential for side effects.
With reputed online pharmacy, you can always be sure that you are getting genuine medicines with active ingredients in the correct amount and without harmful additives. The pharmacy must be regulated by the FDA, then you never need to worry about what is actually present in the pills you are taking.
