So why is this? While a handful of pharma companies have attempted and failed to get rival drugs into the clinic, the sheer scale of the Viagra profit machine created a monopoly, with most companies shying away from the challenge, perceiving it as too much of a risk.

Sexual Medicine: “Needs and Expectations of Patients with Erectile Dysfunction: An Update on Pharmacological Innovations in Phosphodiesterase Type 5 Inhibition with Focus on Sildenafil.” The reported effects were due to a particular molecule known as glyceryl trinitrate or GTN, which causes the dilation of blood vessels in the penis, increasing blood flow. But the reason why Futura were so intrigued was because, while Viagra, Cialis and other drugs have to be taken orally – meaning they reach the target area via the bloodstream and so interact with other systems in the body – GTN could be rapidly absorbed into erectile tissue through the skin. This meant that it could potentially be applied directly as part of a gel or cream, with almost instantaneous results and none of the troublesome side effects associated with Viagra. Sildenafil is the generic version of Viagra, meaning it has the same active ingredient and same dosage as the brand-name medicine. Each is equally effective at creating a short-term reversal of ED symptoms. Pfizer owns Viagra's brand name, giving the pharmaceutical manufacturer the exclusive right to use the term.

One thing is clear: the market is growing. GTN could potentially be applied directly to the penis as a gel or cream, with near instantaneous results It’s not all about food though. Before you take Viagra, generic unbranded Sildenafil, or other PDE-5 inhibitors, ensure that you take into account some other variables that affect the drug’s absorption.

But a 2017 review study found that tadalafil and sildenafil worked in pretty much the same way and had similar side effects. The one big difference was that many of those who took part in the study said they felt more confident when taking tadalafil. This may be because tadalafil's effects last longer -- up to 36 hours versus 12 hours for sildenafil.
