Regardless of perspective, Viagra and Sildenafil are more alike than you think—however it is still great to discuss aspects of Viagra and Sildenafil which you probably do not know about.

How Do You Take Sildenafil?


The drug Viagra is a revolutionary product that changed the way patients with erectile dysfunction are treated. Before, patients had to use a number of uncomfortable devices such as injections, penile suppositories, and pumps to elicit proper erectile function; Viagra, on the other hand, paved the way to systemic, less invasive treatments that can be taken on-demand and that are not embarrassing to use by the patients.
Viagra is classified as a PDE5 inhibitor drug and it is the first of its kind. As a PDE5 inhibitor drug, Viagra is able to encourage greater blood flow to the penis tissues when taken, which translates to proper erectile function in the patients. However, contrary to the common notion, Viagra does not cause spontaneous erections—patients need to be sexually aroused for the drug to function. Viagra works by using the science of sexual arousal and uses the NO-cGMP pathway to carry out its benefits in the patients.
Here are other key facts you need to know about Viagra from Pfizer:
● This drug is initially intended for angina (chest pain) but clinical trial participants ended up getting improved erections as a side effect
● Viagra is not a maintenance medicine—it does not have an aggregated effect and should be taken only as needed
● Patients prescribed with Viagra need to take the drug an hour before the intended sexual activity and preferably without food
● Viagra lasts an average of 4 hours in the patients
● Viagra is a prescription-only drug
● This drug should not be taken with blood pressure lowering medicines, heart medicines, and protease inhibitors
● Common side effects of this drug are stuffy nose, lowered blood pressure, skin flushing, headaches, nausea, and changes in vision.

Sildenafil Citrate

When we speak about Sildenafil, we may actually be referring to two things—the active ingredient Sildenafil Citrate or the “generic” alternatives to Viagra.
Sildenafil Citrate is actually the active ingredient of the drug Viagra and the reason of Viagra’s effectiveness. This means that Viagra vs Sildenafil do not differ at all since Sildenafil Citrate is also Viagra.
On the other hand, Sildenafil, the “generic” alternative to Viagra is more diverse—the generic Sildenafil term includes a wide range of Sildenafil Citrate-containing products with various brand names and manufactured by various pharmaceutical companies. Here are the main differences and similarities between Viagra and Sildenafil (generic Viagra):
● Viagra and generic Sildenafil products have the same active contents and both have the same effect in patients
● Viagra vs Sildenafil pills may look differently since Viagra already patented its diamond-shaped, blue-colored appearance
● Generic Sildenafil products are generally cheaper than brand Viagra
● Since Viagra and Sildenafil have the same active ingredients, buyers can also expect the same effect and side effects in the users.
