Glycol salicylate, also known as 2-hydroxyethyl salicylate, is a benzoate ester formed from the condensation of the carboxy group of salicylic acid with one of the hydroxy groups of ethylene glycol. It is found as an active ingredient and topical analgesic in patches used to provide relief for mild to moderate muscle and joint pain. This drug belongs to the salicylate group of drugs, which are used as analgesic agents for the treatment of mild to moderate pain. Glycol salicylate (GS), composed of salicylic acid (SA) and ethylene glycol, is a non-steroidal anti-inflammatory drug. This ingredient is an important component of many topical creams and sprays for the relief of aches, pains, and stiffness of the muscles, joints, and tendons.

4 Drug and Medication Information
4.1 Drug Indication

This drug is only recommended for topical usages for the relief of muscular and rheumatic pain in human and animals.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Temporarily relieves minor to moderate aches and pains. Works with ingredients such as menthol, which has counter-irritant properties. Counter-irritants are externally applied, and lead to irritation or mild inflammation of the skin to relieve pain in muscles or joints by reducing inflammation in deeper adjacent structures. Counter-irritants relieve pain by disrupting the brain from receiving pain signals resulting from conditions such as osteoarthritis (OA) or injuries such as sprains or strains. These agents may cause vasodilatation or skin irritation, leading to a false sensation of heat or warmth.


5.2 Absorption, Distribution and Excretion

Absorption

Salicylate absorption follows first-order kinetics with an absorption half-life ranging from 5 to 16 minutes.


Route of Elimination

Salicylates are generally excreted.


5.3 Metabolism/Metabolites

The metabolism of glycol salicylate is similar to that of [DB00945] at other salicylates. Metabolism of salicylic acid occurs through glucuronide formation (to produce salicyl acyl glucuronide and salicyl phenolic glucuronide), conjugation with glycine (to produce salicyluric acid), and oxidation to gentisic acid. The rate of formation of salicyl phenolic glucuronide and salicyluric acid are readily saturated at low salicylic acid concentrations and their formation is described by Michaelis-Menten kinetics. The larger the dose administered, the longer it will take to reach steady-state concentrations of salicylates. There is also evidence that enzyme induction of salicyluric acid formation occurs during the metabolism of salicylates.


5.4 Biological Half-Life

The serum half-life of [DB00945], a similar salicylate, is 20 min.


5.5 Mechanism of Action

Similar to other salicylates. Salicylates and other analgesics and anti-inflammatory drugs, particularly the non-steroidal anti-inflammatory drugs (NSAID) mainly used in rheumatology, inhibit cyclooxygenase, therefore reducing prostaglandin synthesis.
