read more about labetalol ...Labetalol blocks alpha-1 adrenergic receptors and beta adrenergic receptors. Alpha-1 blockade reduces peripheral vascular resistance, while beta blockade reduces adrenergic effects on the heart. Together these actions lower blood pressure.
Oral labetalol is used for hypertension and can be used alone or with other antihypertensive medicines. Contraindications include bronchial asthma or obstructive airway disease, decompensated heart failure, greater than first-degree heart block, cardiogenic shock, severe bradycardia, and hypersensitivity to labetalol.
The recommended initial oral dose is 100 mg twice daily. The dose can increase by 100 mg twice daily at intervals of two to three days according to blood pressure response. The recommended maintenance range is 200 mg to 400 mg twice daily.
Serious concerns include symptomatic postural hypotension, syncope, severe bradycardia, heart block, cardiac arrest, and worsening heart failure. Abrupt discontinuation in patients with coronary artery disease can worsen angina and has been associated with myocardial infarction. Heart rate, rhythm, and blood pressure are monitored during treatment.
