Tadalafil 5mg: PDE5 inhibitor for Erectile Dysfunction.
tadalafil at 5 mg is mainly used to treat erectile dysfunction (ED) in men. But it also has other indications:
1. In erectile dysfunction
Mechanism for action:
-Tadalafil inhibits the type 5 phosphodiesterase enzyme (PDE-5), which is responsible for degrading nitrogen monoxide (no)-cyclic guanosin monophosphate dependent (cGMP) in penile cavernous tissue. By inhibiting PDE-5, the concentration of cGMP is increased, resulting in relaxation of smooth muscles of cavernous tissue and allowing greater blood flow to the penis, facilitating erection.
Practical aspects:
-unlike some other ED drugs, tadalafil has a relatively long duration of action. The 5 mg dose is an option for patients who require regular and continuous treatment. It can be taken daily, which allows for greater flexibility in sexual life, as it is not necessary to plan the administration ahead of the time of sexual activity in all cases.
2. In pulmonary arterial hypertension (HTAP)
Mechanism for action:
-also in the pulmonary artery, PDE inhibition-5 per tadalafil results in vascular relaxation. This decreases pulmonary blood pressure by increasing vasodilation of pulmonary blood vessels, improving blood flow and cardiopulmonary function.
Practical aspects:
-in the case of HTAP, the dose and administration are adjusted according to the clinical condition of the patient and are governed by specific medical recommendations for this disorder.
3. In erectile dysfunction associated with certain chronic diseases
Relationship with other diseases:
-in patients with diabetes mellitus, for example, there is an increased risk of developing erectile dysfunction due to vascular and nerve damage that can be caused by the disease in the long term. Tadalafil 5 mg may help improve erectile function in these patients, always under medical supervision, as interaction with other medications they may be taking to control diabetes and other comorbidities should be taken into account.
General considerations:
-the use of tadalafil 5 mg should be prescribed by a doctor, who will evaluate the general health of the patient, including his medical history, medications he is currently taking and possible contraindications. Some side effects may include headache, heartburn, nasal congestion, among others.
