🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively blocking alpha-1 adrenergic receptors, with a higher affinity for the alpha-1A subtype that is predominantly found in the prostate, bladder neck, and urethra. By blocking these receptors, it prevents the binding of norepinephrine and other stress hormones that cause smooth muscle contraction. This leads to relaxation of the smooth muscles in these areas, which reduces the resistance to urine flow and improves urinary symptoms associated with benign prostatic hyperplasia. Unlike some other alpha-blockers, this medicine has a relatively higher selectivity for the alpha-1A receptors, which may result in fewer blood pressure-related side effects.

Additional Safety Advice
Before starting this medicine, it is essential to inform the doctor about all your medical conditions, especially if you have low blood pressure, liver disease, kidney disease, or any planned eye surgery such as cataract removal. This medicine can cause dizziness, so it is advisable to avoid driving or operating heavy machinery until you know how it affects you. To minimize the risk of dizziness when standing up, rise slowly from a sitting or lying position. It is important to stay well hydrated, especially in hot weather or during exercise, to help maintain blood pressure. This medicine should not be taken by women, particularly those who are pregnant or breastfeeding, as it can cause harm to the baby. Men who are taking this medicine and have a pregnant partner should use a condom during sexual intercourse, as small amounts of the medicine can be present in semen and may harm the fetus. Do not share this medicine with others, even if they have the same symptoms. Keep all appointments with your doctor and undergo regular check-ups to monitor your response to the treatment. Do not stop taking this medicine abruptly without consulting your doctor, as this can lead to a worsening of symptoms. Always store this medicine in its original container, away from moisture and heat, and keep it out of reach of children.
