🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly and completely absorbed after oral administration. Food does not significantly affect the extent of absorption, but it may slightly delay the time to peak concentration.
DistributionThis medicine is widely distributed throughout the body. It crosses the blood-brain barrier and the placenta, and it is excreted in breast milk.
Protein BindingApproximately 85% of this medicine is bound to plasma proteins.
MetabolismThis medicine is extensively metabolized in the liver by cytochrome P450 enzymes, including CYP2D6, CYP1A2, and CYP3A4. The main metabolites are demethylmirtazapine and 8-hydroxymirtazapine.
Half-LifeThe elimination half-life of this medicine ranges from 20 to 40 hours. It may be prolonged in elderly patients or those with liver or kidney impairment.
ExcretionThis medicine and its metabolites are excreted primarily in the urine (about 75%) and feces (about 15%).
BioavailabilityThe oral bioavailability of this medicine is approximately 50%.
Onset of ActionSleep improvement may be noticed within the first few days. The full antidepressant effect usually takes 2 to 4 weeks.
Peak Plasma TimePeak plasma concentrations of this medicine are reached about 2 hours after oral administration.
Duration of ActionThe effects of this medicine last for about 24 hours, allowing for once-daily dosing.

How It Works

This medicine works by blocking certain serotonin receptors (5-HT2 and 5-HT3) and histamine H1 receptors, while also enhancing noradrenergic and serotonergic neurotransmission through alpha-2 adrenergic receptor blockade. This leads to increased release of norepinephrine and serotonin in the brain, which helps improve mood, sleep, and appetite.

Mechanism Steps

1
Blockade of alpha-2 adrenergic receptors: This medicine blocks presynaptic alpha-2 adrenergic receptors, which leads to increased release of norepinephrine and serotonin.
2
Antagonism of serotonin 5-HT2 and 5-HT3 receptors: By blocking these receptors, this medicine helps reduce anxiety and nausea, and improves sleep quality.
3
Antagonism of histamine H1 receptors: This action contributes to the sedative effects of this medicine, which can be beneficial for patients with insomnia.
4
Enhanced noradrenergic and serotonergic neurotransmission: The net effect is increased availability of norepinephrine and serotonin in the synaptic cleft, which helps alleviate depressive symptoms.
