Pastillas Erección: Understanding Erectile Dysfunction Pills

"Pastillas de erección" (erection pills) usually refer to medications like sildenafil (Viagra), tadalafil (Cialis) and others.

1. How they work

- These drugs belong to a class called phosphodiesterase type 5 (PDE5) inhibitors.

- In the male sexual response, nitric oxide is released in the penis during sexual stimulation. Nitric oxide activates an enzyme that leads to the production of cyclic guanosine monophosphate (cGMP), which causes smooth muscle relaxation in the penile blood vessels. PDE5 breaks down cGMP. By inhibiting PDE5, these medications allow cGMP to accumulate, leading to increased blood flow into the penis, resulting in an erection.

2. Precautions and side effects

Precautions

- They should be used under medical supervision. They are not suitable for everyone. For example, men who take nitrates (commonly used for heart problems) should not use PDE5 inhibitors as the combination can cause a dangerous drop in blood pressure.

Side effects

- Common side effects may include headache, flushing, nasal congestion, indigestion, and back pain. In rare cases, they may cause vision or hearing problems.

It is important to note that the use of these medications should be based on a proper medical diagnosis of erectile dysfunction and following the advice of a healthcare provider.
