  1. 2. Indications

Tadalafil 20 mg is a medication. Here are some key points about it:

1. Pharmacological properties

Mechanism of action

Tadalafil 20 mg: A Solution for Male Erectile Dysfunction.

- Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme found in the smooth muscle cells of the blood vessels in the penis (in men) and the clitoris (in women). By inhibiting PDE5, tadalafil increases the levels of cyclic guanosine monophosphate (cGMP), which leads to relaxation of the smooth muscles in the blood vessels. This allows increased blood flow into the erectile tissues, facilitating penile erection in men or clitoral engorgement in women.

Absorption, distribution, metabolism, and excretion

Absorption: Tadalafil is relatively well - absorbed after oral administration. It can be taken with or without food, and its absorption is not significantly affected by food.

Distribution: It has a high volume of distribution, which means it is widely distributed throughout the body tissues.

Metabolism: Tadalafil is mainly metabolized in the liver by the cytochrome P450 (CYP) 3A4 enzyme system.

Excretion: The majority of the drug and its metabolites are excreted in feces, with a smaller portion excreted in urine.

Indications

Erectile dysfunction (ED) in men

- It is commonly prescribed to help men with ED achieve and maintain penile erections sufficient for sexual intercourse.

Benign prostatic hyperplasia (BPH) in men

- Tadalafil can also be used to relieve the symptoms associated with BPH, such as difficulty in urination (hesitancy, weak urinary stream, etc.). In some cases, it may be prescribed for both ED and BPH simultaneously.

Pulmonary arterial hypertension (PAH)

- In some countries, tadalafil has been approved for the treatment of PAH. By relaxing the pulmonary arterial smooth muscles, it can reduce pulmonary artery pressure and improve exercise capacity in patients with PAH.

3. Dosage and administration

For erectile dysfunction

- The typical starting dose is 10 mg, which can be adjusted up to 20 mg or down to 5 mg depending on the individual's response and tolerability. The maximum recommended dosing frequency is once per day.

For benign prostatic hyperplasia

- The usual dose is 5 mg once daily. In some cases, the dose may be adjusted based on the patient's symptoms and response.

For pulmonary arterial hypertension

- The recommended dose is 40 mg once daily.

4. Precautions and side effects

Precautions

Medical history: Patients with a history of heart disease, low blood pressure, liver or kidney problems, or those taking medications that interact with tadalafil (such as nitrates, which can cause a dangerous drop in blood pressure when combined with tadalafil) should inform their healthcare provider.

Age: Elderly patients may be more sensitive to the side effects of tadalafil, and dose adjustments may be necessary.

Side effects

- Common side effects may include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. Less common but more serious side effects can include sudden vision or hearing loss, although these are rare.

It is important that tadalafil should only be used under the supervision of a qualified healthcare provider, who can assess the individual's suitability for the treatment, monitor for side effects, and adjust the dose as needed.
