🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionDiphenhydramine is well absorbed from the gastrointestinal tract after oral administration. Menthol is rapidly absorbed through the oral mucosa and gastrointestinal tract.
DistributionDiphenhydramine is widely distributed throughout the body, including the central nervous system. It crosses the placenta and is excreted in breast milk. Menthol distributes to local tissues and is rapidly metabolized.
Protein BindingDiphenhydramine is approximately 98% bound to plasma proteins. Menthol binding is not well established.
MetabolismDiphenhydramine is extensively metabolized in the liver, primarily by cytochrome P450 enzymes, including CYP2D6. Menthol undergoes glucuronidation in the liver and is also metabolized by CYP2A6.
Half-LifeThe elimination half-life of diphenhydramine is approximately 4 to 8 hours. The half-life of menthol is not well established.
ExcretionDiphenhydramine and its metabolites are primarily excreted in the urine. Menthol metabolites are excreted in urine and bile.
BioavailabilityThe oral bioavailability of diphenhydramine is approximately 40% to 60%. The bioavailability of menthol from oral administration is not well established.
Onset of ActionDiphenhydramine begins to work within 15 to 30 minutes after oral administration. Menthol provides immediate cooling relief upon contact with the throat.
Peak Plasma TimePeak plasma concentration of diphenhydramine is reached in about 2 to 3 hours after oral administration. Peak menthol levels are not well established.
Duration of ActionThe effects of diphenhydramine last approximately 4 to 6 hours. Menthol's soothing effect is short-lived and may last for a few minutes to an hour.

How It Works

This medicine combines two active ingredients. Diphenhydramine is a first-generation antihistamine that competitively blocks histamine H1 receptors, reducing allergic symptoms. It also has anticholinergic and sedative effects. Menthol acts as a topical analgesic and counterirritant, providing a cooling sensation by activating TRPM8 receptors, which helps soothe throat irritation.

Mechanism Steps

1
Histamine H1 receptor blockade: Diphenhydramine binds to H1 receptors on effector cells, preventing histamine from triggering allergic responses such as vasodilation, increased vascular permeability, and sensory nerve stimulation.
2
Anticholinergic action: Diphenhydramine also blocks muscarinic acetylcholine receptors, which contributes to dry mouth, blurred vision, and reduced respiratory secretions.
3
Central nervous system depression: Diphenhydramine crosses the blood-brain barrier and causes sedation by blocking histamine and muscarinic receptors in the brain.
4
TRPM8 activation by menthol: Menthol activates TRPM8 receptors on sensory neurons, producing a cooling sensation that masks throat irritation and provides a soothing effect.
