🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is well absorbed after oral administration, and absorption is not significantly affected by food.

DistributionThis medicine is widely distributed in body tissues, including the brain, and it tends to accumulate in fatty tissues with long-term use.

Protein BindingThis medicine is highly bound to plasma proteins, approximately 90% or more.

MetabolismThis medicine is extensively metabolised in the liver by cytochrome P450 enzymes, mainly CYP2D6.

Half-LifeThe elimination half-life of this medicine is long, approximately 18 to 24 days, which allows once-daily dosing and supports gradual build-up of effect.

ExcretionThis medicine and its metabolites are mainly excreted in the bile and faeces, with a smaller amount eliminated through urine.

BioavailabilityThe oral bioavailability of this medicine is not established from the available information.

Onset of ActionThe preventive effect of this medicine usually starts to appear after 2 to 4 weeks of regular use, and full benefit may take 6 to 8 weeks.

Peak Plasma TimePeak plasma levels of this medicine are reached approximately 2 to 4 hours after oral intake.

Duration of ActionBecause of its long half-life, the effect of this medicine lasts for several days after a single dose, and it is usually taken once daily.

How It Works

This medicine works by blocking certain calcium channels in nerve cells and blood vessel walls. By reducing the excessive flow of calcium into these cells, it helps prevent the abnormal electrical activity that can trigger migraines and vertigo. It also helps maintain normal tone in brain blood vessels, which supports steady blood flow and reduces the likelihood of migraine-related changes in the brain.

Mechanism Steps

1

Calcium channel blockade: This medicine binds to calcium channels on nerve and blood vessel cells and reduces the entry of calcium into these cells.

2

Stabilisation of nerve cells: By lowering calcium overload, it stabilises nerve cell membranes and reduces abnormal electrical activity that can trigger migraines.

3

Improved vascular tone: It helps maintain normal tone in brain blood vessels, supporting steady blood flow and reducing migraine-related vascular changes.

4

Reduced vertigo signals: In the inner ear and balance centres, it helps calm abnormal signals that cause dizziness and spinning sensations.
