Polyethylene glycol 300 (PEG 300) is a water-miscible polyether with an average molecular weight of 300 g/mol. It is a clear viscous liquid at room temperature with non-volatile, stable properties. Polyethylene glycols are widely used in biochemistry, structural biology, and medicine in addition to pharmaceutical and chemical industries. They serve as solubilizers, excipients, lubricants, and chemical reagents. Low molecular weight glycols are observed to exhibit antibacterial properties as well. PEG 300 is found in eye drops as a lubricant to temporarily relieve redness, burning and irritation of the eyes.

4 Drug and Medication Information
4.1 Drug Indication

Indicated as a lubricant in over-the-counter ophthalmic solutions to temporarily relieve redness, burning and irritation of the eyes.


5 Pharmacology and Biochemistry
5.1 Pharmacology

PEGs act as nonionic surfactant to decrease surface tension and condition the stratum corneum, thus enhance the diffusion of other molecules or drugs through the skin.


5.2 Absorption, Distribution and Excretion

Absorption

PEGs can be absorbed by the gastrointestinal tract following oral administration with the fraction absorbed being dependent on the molecular weight of the compound. It is likely to display minimal absorption through the intact skin, but may penetrate through injured skin with compromised barrier function.


Route of Elimination

After oral and intravenous exposure, PEGs are excreted mainly unchanged in the urine and faeces.


Volume of Distribution

No pharmacokinetic data available.


Clearance

No pharmacokinetic data available.


5.3 Metabolism/Metabolites

Proportion of absorbed PEGs may be metabolized to lower oligomers, glycolic acid, hydroxyglycolic acids and the diglycolic acids homologs, carbon dioxide that is exhaled, and to a minor extent, oxalic acid.


5.4 Biological Half-Life

No pharmacokinetic data available.


5.5 Mechanism of Action

Due to their physical properties, PEG acts as a surfactant by coating the eye. It provides lubrication and surface protection in dry eyes.
