๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionOral absorption is dose-dependent; low doses (<25 mg) are well absorbed, while higher doses have variable absorption.
DistributionDistributes widely into body tissues, including third-space fluids (pleural effusions, ascites).
Protein BindingApproximately 50% bound to plasma proteins.
MetabolismHepatic metabolism to polyglutamated forms; also undergoes intracellular polyglutamation.
Half-LifeLow dose: 3-10 hours; high dose: 8-15 hours.
ExcretionPrimarily renal excretion via glomerular filtration and active tubular secretion.
BioavailabilityDose-dependent; low doses (โ‰ค25 mg) have ~60% bioavailability, higher doses have lower bioavailabilit
Onset of ActionVariable; antineoplastic effects may take weeks.
Peak Plasma Time1-2 hours after oral administration.
Duration of ActionVariable; prolonged due to intracellular polyglutamation.

How It Works

Inhibits dihydrofolate reductase (DHFR), blocking tetrahydrofolate synthesis and DNA synthesis.

Mechanism Steps

1Methotrexate enters cells via reduced folate carrier (RFC1).
2Intracellularly, it is polyglutamated by folylpolyglutamate synthetase (FPGS).
3Polyglutamated methotrexate inhibits dihydrofolate reductase (DHFR) with high affinity.
