Action
Description: Salicylic acid produces desquamation of hyperkeratotic epithelium via dissolution of the intercellular cement thereby causing swelling, softening, maceration, and desquamation of the cornified tissue. Salicylic acid is keratoplastic (corrects abnormal keratinisation) in low concentrations and keratolytic (causes peeling of the skin) in higher concentrations (1% or higher, depending on the vehicle).
Onset: Treatment of warts: 1-2 weeks.
Pharmacokinetics:
Absorption: Rapidly and efficiently absorbed percutaneously (65-85%). Time to peak plasma concentration: 6-12 hours.
Distribution: Distributed in the extracellular space. Crosses the placenta and enters breast milk. Plasma protein binding: 50-80%, to albumin.
Metabolism: Metabolised in the liver by microsomal enzymes.
Excretion: Mainly via urine (52% as salicyluric acid, 42% as salicylate glucuronides, 6% as salicylic acid).
