🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCaffeine is rapidly absorbed from the gastrointestinal tract after oral administration. Diphenhydramine is also well absorbed orally.
DistributionCaffeine distributes widely throughout body fluids. Diphenhydramine is widely distributed in tissues and crosses the blood-brain barrier.
Protein BindingCaffeine is approximately 25% bound to plasma proteins. Diphenhydramine is about 98% bound to plasma proteins.
MetabolismCaffeine is metabolized in the liver by cytochrome P450 enzymes, primarily CYP1A2. Diphenhydramine is metabolized in the liver, mainly by CYP2D6.
Half-LifeCaffeine half-life is about 3-5 hours. Diphenhydramine half-life is about 4-9 hours.
ExcretionCaffeine metabolites are excreted in urine. Diphenhydramine metabolites are excreted in urine.
BioavailabilityCaffeine oral bioavailability is approximately 100%. Diphenhydramine oral bioavailability is about 40-60%.
Onset of ActionCaffeine onset is within 30-60 minutes. Diphenhydramine onset is within 15-30 minutes.
Peak Plasma TimeCaffeine peak plasma levels occur at 30-60 minutes. Diphenhydramine peak plasma levels occur at 1-2 hours.
Duration of ActionCaffeine effects last 3-5 hours. Diphenhydramine effects last 4-6 hours.

How It Works

Caffeine acts as a central nervous system stimulant by antagonizing adenosine receptors, which leads to increased neuronal firing and release of neurotransmitters like dopamine and norepinephrine. Diphenhydramine is a first-generation antihistamine that competitively blocks histamine H1 receptors, reducing allergic symptoms and causing sedation due to its central nervous system penetration.

Mechanism Steps

1
Adenosine receptor antagonism: Caffeine blocks adenosine receptors in the brain, preventing adenosine from causing drowsiness and promoting wakefulness.
2
Histamine H1 receptor blockade: Diphenhydramine competes with histamine for H1 receptor sites on effector cells, reducing allergic symptoms.
3
Central nervous system effects: Diphenhydramine crosses the blood-brain barrier and causes sedation by blocking central H1 receptors.
