CIALIS 20 MG: Unveiling the Key Facts and Benefits
Guía de Salud Masculina
Cialis (tadalafil) 20 mg is a medication often used to treat erectile dysfunction (ED) in men. Here are some important aspects:
1. Mechanism of action
Inhibition of PDE5: Tadalafil inhibits the enzyme phosphodiesterase type 5 (PDE5). In the penis, this leads to an increase in the levels of cyclic guanosine monophosphate (cGMP). When sexual stimulation occurs, increased cGMP levels cause smooth muscle relaxation in the penile blood vessels, allowing more blood to flow into the penis and resulting in an erection.
Usage and dosage
For erectile dysfunction:
- The recommended starting dose for most men is 10 mg, taken before anticipated sexual activity. However, a 20 - mg dose may be prescribed by a healthcare provider in some cases, depending on the individual's response and tolerability.
- It should not be taken more than once per day.
For benign prostatic hyperplasia (BPH): Tadalafil can also be used to treat the symptoms of BPH. In this case, the usual dose is 5 mg once daily.
3. Precautions and side effects
Precautions:
- Before taking Cialis 20 mg, it is important to inform your doctor about any pre - existing medical conditions, especially heart problems (such as a history of heart attack or stroke), low blood pressure, liver or kidney disease, and any medications you are currently taking.
- Cialis may interact with medications containing nitrates (such as nitroglycerin), which can cause a dangerous drop in blood pressure, so it is contraindicated in patients using nitrates.
Side effects:
- Common side effects may include headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose.
- In rare cases, more serious side effects such as sudden vision or hearing loss may occur, and immediate medical attention should be sought if such symptoms develop.
This medication should only be used under the supervision of a healthcare professional, who can determine if it is appropriate for an individual patient and provide proper dosing instructions.
