🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionPheniramine is well absorbed from the gastrointestinal tract after oral administration. The onset of action is typically within 15 to 30 minutes.
DistributionPheniramine is widely distributed throughout the body, including the central nervous system. It crosses the blood-brain barrier and the placenta.
Protein BindingNot established from the available information.
MetabolismPheniramine is metabolized in the liver, primarily by N-demethylation and oxidative deamination.
Half-LifeThe elimination half-life of pheniramine is approximately 16 to 19 hours.
ExcretionPheniramine and its metabolites are excreted primarily in the urine.
BioavailabilityNot established from the available information.
Onset of Action15 to 30 minutes
Peak Plasma Time1 to 2 hours
Duration of Action4 to 6 hours

How It Works

Pheniramine is a first-generation antihistamine that competitively blocks histamine H1 receptors. By binding to these receptors, it prevents histamine from exerting its effects, which include vasodilation, increased vascular permeability, and sensory nerve stimulation. This leads to reduction in allergic symptoms such as sneezing, itching, and runny nose. Additionally, pheniramine has anticholinergic properties, which contribute to its drying effects and sedation.

Mechanism Steps

1
Histamine release: In an allergic reaction, histamine is released from mast cells and basophils.
2
H1 receptor binding: Pheniramine competes with histamine for binding to H1 receptors on target cells.
3
Blockade of histamine effects: By occupying H1 receptors, pheniramine prevents histamine from inducing vasodilation, increased permeability, and sensory nerve stimulation.
4
Anticholinergic action: Pheniramine also blocks muscarinic acetylcholine receptors, contributing to drying effects and sedation.
5
Central nervous system depression: Pheniramine crosses the blood-brain barrier and causes sedation by blocking histamine in the brain.
