Tương tác
Increased effect or plasma concentration with CYP2C9 and CYP3A4 inhibitors (e.g. cimetidine, fluconazole, amiodarone). Decreased effect or plasma concentration with rifampicin. Terbinafine increases the effect of TCAs (e.g. desipramine), beta-blockers (e.g. atenolol), SSRIs (e.g. escitalopram), MAOIs (e.g. rasagiline) by inhibiting CYP2D6 enzyme. Decreases the clearance of caffeine. Increases the clearance of ciclosporin.
Tác dụng
Description: Mechanism of Action: Terbinafine is a synthetic allylamine derivative that interferes with fungal sterol biosynthesis by inhibiting squalene epoxidase. This results in a deficiency in ergosterol and intracellular accumulation of squalene within the fungal cell membrane, leading to fungal cell death. Pharmacokinetics: Absorption: Well absorbed from the gastrointestinal tract (>70%). Bioavailability: Approx 40%. Time to peak plasma concentration: Within 2 hours. Distribution: Distributed mainly to stratum corneum, sebum, hair, and nail matrix, bed, and plate. Enters breast milk. Plasma protein binding: >99%. Metabolism: Rapidly and extensively metabolised in the liver mainly by CYP1A2, CYP3A4, CYP2C8, CYP2C9, and CYP2C19 to inactive metabolites. Undergoes first-pass metabolism. Excretion: Mainly via urine (80%, as inactive metabolites); faeces (20%). Plasma elimination half-life: 200-400 hours (terminal); approx 36 hours (effective).
