Lopressor HCT - General Information

A selective adrenergic beta-1-blocking agent with no stimulatory action. It&

Pharmacology of Lopressor HCT

Lopressor HCT, a competitive, beta1-selective (cardioselective) adrenergic antagonist, is similar to atenolol in its moderate lipid solubility, lack of intrinsic sympathomimetic activity (ISA), and weak membrane stabilizing activity (MSA).

Lopressor HCT for patients

Metoprolol succinate is used to treat high blood pressure alone or in combination with other medications. This medication can also be used to treat a heart condition called angina. This particular formulation is an extended release product, meaning it can be taken once a day. This medication should be taken as directed, with a meal or right after a meal. The tablets should not be broken or crushed. Do not take a double dose if a dose is missed. This medication should not be stopped abruptly; it should be discontinued slowly over time. If you are taking this medication for high blood pressure, make sure to have your blood pressure checked regularly. If you ever have trouble breathing, call your physician immediately. The most common adverse effects are dizziness and tiredness. It is important to inform all your healthcare providers that you are taking this medication, especially before any surgeries or procedures.

Lopressor HCT Interactions

Catecholamine-depleting drugs (e.g., reserpine) may have an additive effect when given with beta-blocking agents. Patients treated with extended release metoprolol succinate plus a catecholamine depletor should therefore be closely observed for evidence of hypotension or marked bradycardia, which may produce vertigo, syncope, or postural hypotension.

Lopressor HCT Contraindications

Hypertension and Angina: Extended release metoprolol succinate is contraindicated in sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure

Additional information about Lopressor HCT

Lopressor HCT Indication: For the treatment of hypertension and angina pectoris.
Mechanism Of Action: Like betaxolol and atenolol, metoprolol competes with adrenergic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart and vascular smooth muscle. Beta(1)-receptor blockade results in a decrease in heart rate, cardiac output, and blood pressure.
