Cialis in action

There are so many different medications for erectile dysfunction on the market today that it is difficult to know which to choose. However, having an understanding of the chemistry behind the pharmaceuticals might make it easier to know which drug treatment is the most appropriate.

What does Cialis do?

Cialis is the brand name for the phosphodiesterase type 5 inhibiting medication tadalafil. Cialis (and other PDE5 inhibitors) prevent the production of the PDE5 enzyme that prevents the body's production of cyclic GMP, a naturally occurring chemical that allows the relaxation of the walls of the corpus cavernosum so that blood can flow sufficiently.

What makes Cialis unique is the fact that it treats not only ED, but also benign prostatic hyperplasia (BPH) a condition characterized by an inflammation of the prostate, leading to difficult, frequent and/or urgent urination. ED and BPH are not related conditions, but they can coexist, nonetheless.

Unlike the other drugs currently on the market, when you buy Cialis, you can rest assured that it can be taken as a daily drug or on an as needed basis. Patients who choose the option of taking it daily might also use it for treatment of BPH, but it can also be used by patients who want the option of being ready to achieve an erection at any time.

Cialis also differs from other ED drugs in that the as-needed version has a far longer active life that other competing drugs. While other ED medications last between four and five hours, a single dose of Cialis lasts for up to 36 hours, so a patient can take it on Friday afternoon and still be ready to achieve an erection by Saturday night.

Is Cialis right for me?

Men suffering from ED might also have underlying medical conditions causing it. These conditions include:

  • Obesity
  • Diabetes
  • Hypertension
  • Penis scars
  • Stress
  • Alcohol or drug addiction
  • Depression

It is very important to seek advice from a physician before undergoing any pharmaceutical treatment for erectile dysfunction, since the different medications necessary for the various conditions might conflict with PDE5 inhibitors.

Because Cialis is an enzyme inhibitor, it also slows the production of other enzymes, occasionally resulting in mild side effects. These side effects include blurry vision, reduced blood pressure, flushing and mild headache.

When deciding to buy Cialis, it is important to remember that it does not cause erections; it merely slows the production of the enzyme that prevents sufficient blood flow to the penis. In order to achieve an erection, the patient must still become sexually aroused.
