🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. However, it undergoes significant first-pass metabolism in the liver, which reduces its bioavailability.
DistributionThis medicine is highly lipophilic and distributes widely into body tissues, including the brain. It crosses the blood-brain barrier and the placenta, and is excreted in breast milk.
Protein BindingApproximately 90% bound to plasma proteins, primarily albumin.
MetabolismThis medicine is extensively metabolized in the liver, primarily by the CYP2D6 and CYP1A2 enzymes. It has a significant first-pass effect, and its metabolites are excreted in urine.
Half-LifeThe elimination half-life is approximately 3 to 6 hours for immediate-release formulations.
ExcretionThis medicine and its metabolites are primarily excreted in the urine.
BioavailabilityApproximately 25% to 30% due to first-pass metabolism.
Onset of ActionThe onset of action is typically within 30 to 60 minutes after oral administration for immediate-release tablets.
Peak Plasma TimePeak plasma concentrations are reached approximately 1 to 2 hours after oral administration.
Duration of ActionThe duration of action is approximately 6 to 12 hours for immediate-release formulations, but this can vary depending on the indication and individual factors.

How It Works

This medicine works by blocking beta-adrenergic receptors, which are found in the heart, blood vessels, and other tissues. By blocking these receptors, it prevents the effects of adrenaline and noradrenaline, leading to a slower heart rate, reduced force of heart contractions, and decreased blood pressure. This reduces the workload on the heart and helps to control symptoms of angina and arrhythmias. In migraine prevention, the exact mechanism is not fully understood, but it may involve effects on blood vessels and brain chemicals.

Mechanism Steps

1
Binding to beta receptors: This medicine binds to beta-adrenergic receptors on the surface of cells in the heart, blood vessels, and other tissues.
2
Blockade of adrenaline effects: By occupying these receptors, it prevents adrenaline and noradrenaline from binding and exerting their stimulatory effects.
3
Reduced heart rate and contractility: This leads to a slower heart rate and decreased force of heart contractions, reducing the heart's oxygen demand.
4
Lowered blood pressure: The reduced cardiac output and decreased renin release contribute to lowering blood pressure.
5
Additional effects: In the brain, it may affect serotonin receptors and other pathways, which helps prevent migraines and reduce anxiety symptoms.
