Salicylic acid is keratolytic producing desquamation by solubilising the
intercellular cement in the stratum corneum.
Salicylic acid is absorbed percutaneously with maximal plasma levels after 6 12 hours; 65-85% of the dose is absorbed.
Following percutaneous absorption, salicylic acid is distributed in the
extracellular space and 58% is protein bound to albumin. Salicylates cross the
placenta and appear in breast milk.
Salicylates are metabolised in the liver by microsomal enzymes and either
conjugated with UDP-glucuronic acid to form phenyl or acyl glucuronides or
hydroxylated into gentisic acid. In the liver and kidneys, the carboxyl groups
are conjugated in the mitochondria to form salicylates or gentisurates.
65- 85% of topically administered salicylates are recoverable in the urine, 52%
of which are in the form of salicyluric acid, 42% as phenolic glucuronides of
salicylic acid and the rest as salicylic acid. Of a single dose, 95% is excreted
within 24 hours of its entry into the extracellular space.
Preclinical safety data
