🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionMetoprolol succinate is well absorbed from the gastrointestinal tract. Chlorthalidone is also absorbed from the gastrointestinal tract. Food does not significantly affect the absorption of metoprolol succinate. The bioavailability of metoprolol succinate is approximately 50% due to first-pass metabolism. Chlorthalidone bioavailability is approximately 65%.
DistributionMetoprolol is widely distributed in body tissues, with a volume of distribution of about 3.2 L/kg. It crosses the blood-brain barrier and placenta. Chlorthalidone is distributed mainly in extracellular fluid and is highly bound to red blood cells. It also crosses the placenta.
Protein BindingMetoprolol is approximately 12% bound to plasma proteins. Chlorthalidone is about 75% bound to plasma proteins, primarily albumin.
MetabolismMetoprolol undergoes extensive first-pass metabolism in the liver, primarily by CYP2D6. Chlorthalidone is not significantly metabolized and is excreted largely unchanged.
Half-LifeThe elimination half-life of metoprolol is approximately 3-7 hours. Chlorthalidone has a long half-life of about 40-60 hours.
ExcretionMetoprolol is excreted mainly in the urine as metabolites. Chlorthalidone is excreted primarily unchanged in the urine.
BioavailabilityMetoprolol succinate: approximately 50%. Chlorthalidone: approximately 65%.
Onset of ActionMetoprolol: within 1-2 hours. Chlorthalidone: diuretic effect within 2-3 hours; antihypertensive effect may take several days to weeks.
Peak Plasma TimeMetoprolol: 3-7 hours for extended-release. Chlorthalidone: 2-6 hours.
Duration of ActionMetoprolol: 24 hours for extended-release. Chlorthalidone: 24-72 hours.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Metoprolol Succinate is a cardioselective beta-1 adrenergic receptor blocker that reduces heart rate, cardiac output, and renin release. Chlorthalidone inhibits sodium reabsorption in the distal convoluted tubule of the kidney, increasing excretion of sodium, chloride, and water, which reduces plasma volume and peripheral vascular resistance.

Mechanism Steps

1
Beta-1 receptor blockade: Metoprolol selectively blocks beta-1 adrenergic receptors in the heart, reducing sympathetic stimulation.
2
Reduced cardiac output: This leads to a slower heart rate and decreased force of contraction, lowering cardiac output and blood pressure.
3
Inhibition of renin release: Beta-1 blockade in the kidneys reduces renin secretion, decreasing angiotensin II and aldosterone levels.
4
Diuretic action: Chlorthalidone inhibits sodium reabsorption in the distal tubule, increasing sodium and water excretion.
5
Volume reduction: The diuretic effect reduces plasma volume and extracellular fluid, contributing to blood pressure lowering.
