What is rilmenidine?

Rilmenidine

Rilmenidine is an antihypertensive medication used to treat high blood pressure (hypertension). It belongs to a class of drugs called selective imidazoline I1-receptor agonists.

• Mechanism of Action: Rilmenidine works by selectively binding to and stimulating imidazoline I1-receptors in the brain. This action reduces sympathetic nervous system activity, leading to a decrease in heart rate and blood vessel constriction, ultimately lowering blood pressure. Unlike some older antihypertensives, rilmenidine has a higher selectivity for I1-receptors compared to alpha-2 adrenergic receptors, which can minimize certain side effects.

• Indications: It is primarily indicated for the treatment of mild to moderate essential hypertension.

• Dosage and Administration: The typical starting dose is usually one tablet (1 mg) daily, taken in the morning. Depending on the patient's response, the dose may be increased to 2 mg daily.

• Side Effects: Common side effects may include fatigue, palpitations, insomnia, drowsiness, anxiety, depression, gastrointestinal disturbances (such as nausea, constipation, or diarrhea), and skin reactions.

• Contraindications: Rilmenidine is contraindicated in patients with severe renal impairment, severe liver disease, and a history of hypersensitivity to the drug.

• Precautions: Caution should be exercised when using rilmenidine in patients with a history of depression, heart failure, or postural hypotension. It can enhance the effects of central nervous system depressants.

• Drug Interactions: Rilmenidine can interact with other medications, including other antihypertensives, central nervous system depressants (such as alcohol and sedatives), and some antidepressants.

• Pregnancy and Lactation: Its safety during pregnancy and breastfeeding has not been fully established, so it should only be used if the potential benefits outweigh the risks.

• Pharmacokinetics: Rilmenidine is well absorbed after oral administration and has a relatively long half-life, allowing for once-daily dosing.
