What is the difference between viagra and sildenafil citrate

Thanks to science, ED can be optional. Sildenafil has been available since , when it was approved by the FDA under the product name Viagra as a medication for erectile dysfunction. Interestingly, sildenafil was originally intended as a treatment for cardiovascular diseases such as pulmonary arterial hypertension, or increased blood pressure in the arteries of the lungs.

In some cases, sildenafil is still used today for this purposes. Pfizer patented sildenafil in and gained FDA approval to sell the medication in The patent for Viagra expired in for countries outside the United States, allowing for the sale of generic sildenafil. They have the same effect on your ability to maintain an erection. Important note: The bioequivalence also means you need to steer clear of both Sildenafil and Viagra if you have been medically advised against taking either of them.

Sildenafil and Viagra both work by inhibiting the PDE5 enzyme, which controls muscle contraction in the penis. The drug allows the blood vessels in the penis to relax and expand, boosting the blood flow to the area and making it easier to maintain a lasting erection. However, these side-effects tend to be mild and temporary, so they might not be a reason to avoid trying ED medication. For most men and their partners , the benefits outweigh the risks. Some potential side-effects include headache and dizziness, hot flushes, indigestion, blurred vision, and nasal congestion.

In truth, the differences are minimal and mostly trivial in nature. The main difference between Sildenafil and Viagra is the price. Branded Viagra tablets , thanks to their high-profile name, regularly cost over three times as much as the unbranded Sildenafil.

While some may prefer to pay the high price for the familiar brand name, there is no practical or medical reason to do so. A lower price for medication especially when ordered online might ring alarm bells for some people, but credible licensed suppliers are legitimately able to supply these drugs for cheaper.

The other difference between Sildenafil and Viagra can be the appearance of the tablets themselves. Yes, there are other branded and generic medications available in the UK for ED. For example, Tadalafil is the generic version of the brand Cialis, Vardenafil is the unbranded version of Levitra, and Avanafil is the generic version of Spedra.

All of these drugs are PDE5 inhibitors, so they all work in a similar way to Sildenafil and Viagra to help men with erectile dysfunction. Clinically proven to help you get an erection when you need it. So there you have it. You can combat this condition with safe, reliable, and medically-approved drugs — ordered online for an affordable price.

Sildenafil is a game-changer. If you suffer from erectile dysfunction ED then it is absolutely okay to take the prescribed amount of either Viagra or Sildenafil both work the same. However, it is not safe or healthy to take ED medication if you have not been prescribed it, or do not suffer from erectile dysfunction.

Recreational ED medication use can be harmful to your physical and mental health. Sildenafil, the active ingredient in Viagra, was invented by American pharmaceutical company Pfizer in the s. In , Pfizer patented their Sildenafil medication as Viagra. Sildenafil was then studied in men with erectile dysfunction, and in it was approved by the FDA specifically for treatment of ED. It costs a fraction of the price of Viagra, and has made the treatment more accessible to a wider range of patients.

Branded Viagra comes in small diamond-shaped blue pills — Pfizer has also patented this pill design and appearance. Sildenafil is sold as white or blue tablets, with different characteristics depending on the brand.

Some have chalky finishes while others are smooth, and some are scored for easy division, while others are not. Both Viagra and the different brands of sildenafil can be purchased in 25mg, 50mg, and mg preparations, and there is no significant difference between them in terms of active ingredients. As a generic medicine, sildenafil is produced by a number of manufacturers, and competition among them helps to regulate its price and keep it affordable for consumers.

Viagra and sildenafil are medically the same. It is a requirement for the generic version to contain the same levels of the active ingredient in the body as its branded alternative, which is known as bioequivalence.

Before generic drugs are licensed for sale the manufacturer must demonstrate bioequivalence to the licensing authorities the European Medicines Agency. If you have a private prescription for Viagra, the branded drug must be dispensed; but you may ask for sildenafil at the time that the prescription is made. They are considered equally effective, however patients must follow proper protocol for optimum results.
