The famous 비아그라 판매 (Sildenafil) began to be marketed in 1998 and was a real revolution, as it was the first oral drug capable of reliably producing an erection .
As on so many other occasions in the history of medicine, its discovery was accidental : a medicine used for the heart accidentally induced erections. From there, research began and the subsequent development of the drug. The final effect of the drug is vasodilation of the blood vessels of the penis.
It became the best-selling drug in the world and, in the first 3 months of 1998, Pfizer (the laboratory that developed it) earned more than 400 million dollars. According to some estimates, in recent decades 비아그라 판매 has generated annual sales of more than 1,800 million dollars.
Recently the British newspaper The Guardian published an article showing the effort being made by the pharmaceutical industry to find new drugs for the treatment of erectile dysfunction, now that the patents on the market are running out, which allows generic laboratories can launch drugs on the market at a lower cost to the patient.
Without a doubt, this is an emerging market: in the year 2025, more than 300 million men in the world will suffer from erectile dysfunction . The increase in longevity, vascular diseases and obesity, together with the desire to maintain an active sexual life for more years, means that more and older men come to our consultations. More and more patients over 80 years of age who want to continue enjoying sex.
Since the appearance of 비아그라 판매, 3 other oral drugs have fundamentally emerged , which differ in their doses (some are daily doses and others act faster) and effects. The final purpose is to prevent the relaxation of the penis when it reaches an erection, as long as there is sexual desire. In general, the answer is usually positive in 70% of cases. For most of these drugs, taking food can reduce their effects.
The later arrival of Cialis (Tadalafil) also revolutionized treatment. With a period of action of more than 30 hours, men could use this drug during the weekend without having to be aware of its intake 1 hour before intercourse.
The most common side effects of erection medications are headache, stomach upset, and/or muscle pain, although they usually go away. They are drugs that throughout history have shown a very high safety profile
