🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLoratadine is rapidly absorbed from the gastrointestinal tract after oral administration. The syrup formulation is designed for easy swallowing and rapid absorption, especially in children and those who have difficulty with tablets.
DistributionLoratadine is widely distributed in the body. It is approximately 97% to 99% bound to plasma proteins. It does not readily cross the blood-brain barrier, which contributes to its non-sedating profile.
Protein BindingApproximately 97% to 99% bound to plasma proteins.
MetabolismLoratadine is extensively metabolized in the liver, primarily by the cytochrome P450 enzyme CYP3A4 and to a lesser extent by CYP2D6. The major metabolite is descarboethoxyloratadine (DCL), which is also pharmacologically active.
Half-LifeThe elimination half-life of loratadine is approximately 8 to 14 hours in healthy adults. The half-life of its active metabolite, descarboethoxyloratadine, ranges from 17 to 24 hours.
ExcretionLoratadine and its metabolites are excreted primarily in the urine and feces. About 40% of the dose is excreted in the urine and 42% in the feces over a 10-day period.
BioavailabilityThe oral bioavailability of loratadine is approximately 40% due to first-pass metabolism.
Onset of ActionThe onset of action is typically within 1 to 3 hours after oral administration.
Peak Plasma TimePeak plasma concentrations of loratadine are reached approximately 1 to 1.5 hours after oral administration. The peak concentration of the active metabolite occurs at about 1.5 to 3.7 hours.
Duration of ActionThe duration of action is approximately 24 hours, allowing for once-daily dosing.

How It Works

Loratadine is a long-acting tricyclic antihistamine with selective peripheral histamine H1-receptor antagonist activity. It works by competing with histamine for binding sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract. By blocking H1 receptors, it prevents histamine-mediated symptoms such as vasodilation, increased vascular permeability, itching, sneezing, and mucus secretion. Unlike first-generation antihistamines, loratadine does not readily cross the blood-brain barrier, which explains its low incidence of sedation.

Mechanism Steps

1
Histamine release: In an allergic reaction, mast cells release histamine, which binds to H1 receptors on target cells.
2
Competitive antagonism: Loratadine competes with histamine for binding to H1 receptors, preventing histamine from exerting its effects.
3
Reduction of allergic symptoms: Blockade of H1 receptors leads to decreased vasodilation, vascular permeability, itching, and mucus production.
4
Limited CNS penetration: Loratadine poorly crosses the blood-brain barrier, resulting in minimal sedation.
