🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAfatinib is absorbed from the gastrointestinal tract after oral administration. The absolute bioavailability is not established from the available information. Food does not significantly affect the absorption of afatinib.
DistributionAfatinib is distributed widely into body tissues. It is highly bound to plasma proteins. The volume of distribution is not established from the available information.
Protein BindingAfatinib is approximately 95% bound to plasma proteins.
MetabolismAfatinib undergoes minimal metabolism. It is primarily metabolised by cytochrome P450 enzymes, mainly CYP3A4, but also by CYP2D6 and CYP2C9, to a small extent. The main metabolite is a covalent adduct with cysteine residues.
Half-LifeThe terminal elimination half-life of afatinib is approximately 28 to 36 hours.
ExcretionAfatinib is primarily excreted in the faeces (about 85%) and urine (about 4%) as unchanged drug. The remainder is excreted as metabolites.
BioavailabilityThe absolute bioavailability of afatinib in humans is not established from the available information.
Onset of ActionThe onset of action is not immediate; it takes several days to weeks for clinical effects to become apparent. Steady-state plasma concentrations are reached within 8 days of daily dosing.
Peak Plasma TimeThe peak plasma concentration of afatinib is reached approximately 2 to 5 hours after oral administration.
Duration of ActionThe duration of action is not directly established, but due to irreversible binding, the effects persist beyond the presence of the drug in plasma. The half-life is about 28-36 hours, so the effect may last for several days after stopping.

How It Works

Afatinib is a potent, irreversible inhibitor of the ErbB family of tyrosine kinases, which includes EGFR (ErbB1), HER2 (ErbB2), ErbB3, and ErbB4. It covalently binds to the ATP-binding site of these receptors, leading to irreversible inhibition of autophosphorylation and downstream signalling. This blocks pathways that promote cell proliferation, survival, migration, and angiogenesis. In cancer cells with activating EGFR mutations, afatinib effectively suppresses tumour growth and induces apoptosis. Because it is irreversible, its effects last longer than reversible inhibitors, but it also contributes to its toxicity profile.

Mechanism Steps

1
Binding to EGFR family receptors: Afatinib covalently binds to the ATP-binding pocket of EGFR, HER2, ErbB3, and ErbB4, forming an irreversible bond.
2
Inhibition of autophosphorylation: This binding prevents the receptors from autophosphorylating, which is necessary for their activation.
3
Blockade of downstream signalling: As a result, downstream signalling pathways such as MAPK and PI3K/AKT are inhibited, which are crucial for cell growth and survival.
4
Induction of apoptosis and growth arrest: Cancer cells with EGFR mutations undergo programmed cell death and stop dividing, leading to tumour shrinkage.

Dosage Information

Adult DosageThe recommended dose of this medicine is 40 mg taken orally once daily until disease progression or unacceptable toxicity occurs. For patients with severe renal impairment (creatinine clearance 15-29 mL/min), the dose may be reduced to 30 mg once daily. For patients with severe hepatic impairment, dose reduction may be necessary. Dose adjustments may also be required for adverse reactions such as diarrhoea, skin reactions, or other toxicities. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and tolerability.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageNo specific dose adjustment is recommended for elderly patients based on age alone. However, elderly patients may be more susceptible to adverse effects such as diarrhoea and dehydration. Monitor closely and adjust dose as needed based on renal and hepatic function.
Renal ImpairmentFor patients with severe renal impairment (creatinine clearance 15-29 mL/min), the recommended dose is 30 mg once daily. For patients with end-stage renal disease or on dialysis, afatinib is not recommended. No dose adjustment is needed for mild to moderate renal impairment.
Hepatic ImpairmentFor patients with severe hepatic impairment (Child-Pugh C), the recommended dose is 30 mg once daily. No dose adjustment is needed for mild to moderate hepatic impairment. Monitor liver function closely.
Maximum Daily DoseThe maximum recommended daily dose is 40 mg. In some cases, dose escalation to 50 mg may be considered in patients who tolerate 40 mg without significant adverse effects, but this is not routinely recommended.
