Pastillas Erección: Unraveling the Mystery of These Pills

"Pastillas de erección" (erection pills) are medications often used to treat erectile dysfunction.

1. Common types and how they work

Sildenafil (Viagra):

- It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.

- Normally, in the penis, an enzyme called PDE5 breaks down a chemical called cyclic guanosine monophosphate (cGMP). cGMP is important for relaxing the smooth muscles in the blood vessels of the penis, allowing increased blood flow, which is necessary for an erection. Sildenafil inhibits PDE5, thus increasing the levels of cGMP and promoting blood flow to the penis when sexual stimulation occurs.

Tadalafil (Cialis):

- Also a PDE5 inhibitor.

- It has a relatively long - acting effect compared to sildenafil. Tadalafil can help men achieve and maintain an erection for a longer period, sometimes up to 36 hours in some cases.

Vardenafil (Levitra):

- Another PDE5 inhibitor.

- It works in a similar way to sildenafil and tadalafil, by enhancing the effects of nitric oxide - mediated vasodilation in the penile arteries, which leads to increased blood flow and penile erection.

2. Precautions and side effects

Precautions:

- These medications should be used under medical supervision. They are not suitable for everyone, especially those with certain underlying health conditions such as severe heart problems, low blood pressure, or those taking nitrate medications (as the combination can cause a dangerous drop in blood pressure).

Side effects:

- Common side effects may include headache, flushing (redness of the face and neck), nasal congestion, indigestion, and in some cases, vision problems (although rare).

It's important that men experiencing erectile problems consult a healthcare provider to determine the most appropriate treatment option, rather than self - medicating with these types of pills.
