🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is well absorbed from the gastrointestinal tract after oral administration. Food does not significantly affect its absorption.
DistributionIt is widely distributed throughout the body, including the brain. It crosses the blood-brain barrier and the placenta, and is excreted in breast milk.
Protein BindingApproximately 80-90% bound to plasma proteins.
MetabolismThis medicine is extensively metabolized in the liver, primarily by demethylation and glucuronidation. Some metabolites may be active.
Half-LifeThe elimination half-life is approximately 14-24 hours, but it can be longer in elderly patients or those with liver impairment.
ExcretionMetabolites are excreted mainly in the urine and to a lesser extent in the feces.
BioavailabilityThe oral bioavailability is approximately 30-50% due to first-pass metabolism.
Onset of ActionThe antidepressant effect usually takes 2-4 weeks to become noticeable, but side effects such as dry mouth and drowsiness may occur within hours of the first dose.
Peak Plasma TimePeak plasma concentrations are reached about 2-4 hours after oral administration.
Duration of ActionThe pharmacological effects last for about 24 hours, allowing for once-daily dosing in most patients.

How It Works

This medicine works by blocking the reuptake of serotonin and noradrenaline in the brain. These are neurotransmitters that help regulate mood, emotion, and pain perception. By preventing their reabsorption into nerve cells, the medicine increases their availability in the synaptic gap, which helps to improve mood and reduce pain signals. It also has anticholinergic effects, which can cause dry mouth, constipation, and blurred vision, and antihistamine effects, which contribute to drowsiness.

Mechanism Steps

1
Inhibition of serotonin reuptake: This medicine binds to the serotonin transporter and blocks the reuptake of serotonin into presynaptic neurons, increasing serotonin levels in the synapse.
2
Inhibition of noradrenaline reuptake: It also blocks the noradrenaline transporter, leading to higher noradrenaline levels in the synaptic cleft.
3
Antagonism of muscarinic receptors: The medicine blocks muscarinic acetylcholine receptors, which causes dry mouth, constipation, blurred vision, and urinary retention.
4
Antagonism of histamine H1 receptors: Blockade of histamine H1 receptors contributes to sedation and weight gain.
5
Antagonism of alpha-1 adrenergic receptors: This action can lead to orthostatic hypotension and dizziness.
