5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Oily phenol injection acts as an analgesic and thrombotic agent by numbing the sensory nerve endings and precipitating proteins.

5.2 Pharmacokinetic properties

Phenol is absorbed from the gastro-intestinal tract and through skin and mucous membranes. It is metabolised to phenylglucoronide and phenylsulphate and small amounts are oxidised to catechol and quinol which are mainly conjugated. The metabolites are excreted in the urine; on oxidation to quinones they may tint the urine green.
