🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Labetalol is a combined alpha- and beta-adrenergic receptor blocker. It competitively blocks beta-adrenergic receptors, which reduces heart rate and cardiac output, and also blocks alpha-adrenergic receptors, leading to vasodilation. This dual action results in a decrease in blood pressure without a significant reduction in heart rate at usual doses.
Mechanism Steps
💡 How to Take labeta injection
Strength: Labetalol is available as 100 mg, 200 mg, and 300 mg tablets. This product is a 100 mg tablet.
Dosage Information
| Adult Dosage | The usual starting dose for hypertension is 100 mg twice daily, which may be increased gradually based on response. For pregnancy-induced hypertension, doses may range from 100 mg to 400 mg twice daily. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |

| Elderly Dosage | Elderly patients may be more sensitive to the effects of labetalol. Start with a lower dose and titrate slowly. Monitor blood pressure and heart rate closely. |
| Renal Impairment | No specific dose adjustment is usually required for mild to moderate renal impairment. In severe renal impairment, use with caution and monitor. |
| Hepatic Impairment | Use with caution in patients with hepatic impairment. Dose reduction may be necessary. Monitor liver function. |
| Maximum Daily Dose | The maximum recommended daily dose is 2400 mg, but doses above 800 mg are rarely used. Individualized by clinician. |
