Drug

D0470 | erlotinib

Molecular Formula C22H23N3O4
Molecular Weight 393.4
Structure
State solid
Clearance Smokers have a 24% higher rate of erlotinib clearance.
Volume of distribution Apparent volume of distribution = 232 L
Route of elimination Following a 100 mg oral dose, 91% of the dose was recovered in which 83% was in feces (1% of the dose as unchanged parent compound) and 8% in urine (0.3% of the dose as unchanged parent compound).
Protein binding 93% protein bound to albumin and alpha-1 acid glycoprotein (AAG)
Half life Median half-life of 36.2 hours.
Absorption Erlotinib is about 60% absorbed after oral administration and its bioavailability is substantially increased by food to almost 100%. Peak plasma levels occur 4 hours after dosing. The solubility of erlotinib is pH dependent. Solubility decreases pH increases. Smoking also decrease the exposure of erlotinib.
