What is Cialis?

Cialis is a brand name of the Tadalafil based drug manufactured by the company Eli Lilly. Tadalafil was developed by Eli Lilly. Cialis is used to treat erectile dysfunction in men.

Cialis (Tadalafil) is the third among the most popular PDE-5 inhibitors. The first was Viagra (Sildenafil) by Pfizer and the second was Levitra (Vardenafil) by Bayer Pharmaceuticals.

Cialis is used to manage erectile dysfunction. Tadalafil increases the blood flow in the penis and the erection is strong and long. Cialis induces erection only in the presence of sexual stimulation. The medication itself does not induce erection.

Cialis was approved by the U.S Food and Drug Administration (FDA) in 2003.

Cialis also for benign prostatic hypertrophy.

Cialis is not the only Tadalafil based drug. Another one is Adcirca by Eli Lilly for pulmonary arterial hypertension. Tadalafil improves blood circulation not only in the pelvic organs but also in the lungs.

What you should know before taking Cialis

Male erection is a complex reaction to sexual stimulation which involves not only the penis. The brain, nerve cells, hormones are all responsible for the erection. Erectile dysfunction is a sign that some of these systems fail to function properly.

Diabetes, heart diseases, stress, nervous disorders, Parkinson’s disease can cause erection problems. Certain medications are also responsible for this condition.

So the first thing to do when you notice erection problems is to visit a doctor and find out the cause.

Cialis generics

A generic drug is a pharmaceutical drug that has the same chemical substance as the drug that was originally developed.

When a company is developing a new medication, its active substance is thoroughly tested and studied. Of course, laboratory and clinical studies cost millions of dollars. The drug developer obtains a patent that gives it exclusive rights to manufacture and sell the medication. No other company is allowed to manufacture the drug while the patent is in force. The drug developer can set the price for its drug and in this way, the company may return its investments in the research and development activities.

When the term of the patent expires, other companies are entitled to manufacture drugs with this active substance. These drugs become generics.

Legal generics are not counterfeit drugs as they are also tested and studied and approved before entering the market.

However, we may find illegal generics even before the term of the patent expires.

Typically third countries manufacture illegal generics and India is especially active. These generics are not tested for safety and initially, they are meant for the local market of third countries.

However, due to their low price and availability, over time they enter the markets in developed countries. One does not need a prescription or other documents to buy illegal generics online. This fact attracts men who are too shy to go to a doctor.

Actually, there are no official generics of Cialis today. Both Tadalafil based medications – Cialis and Adcirca – are manufactured by the company Eli Lilly only. Its patent expires in spring 2020 but it may be extended.

Where can I buy Cialis? Can I buy Cialis without a prescription?

Cialis is available only with a doctor’s prescription. Even online drugstores require a copy of your prescription.

Illegal generics of Cialis are available with no prescription in certain online drugstores. However, buying them you are at a risk to have serious side effects.

Conclusion

Tadalafil based Cialis is a solution for many men around the world. This medication is second only to Viagra. It has a positive effect, minimum side effects and its duration of action is up to 36 hours.
