2,4-Dichlorobenzyl alcohol Usage And Synthesis

Chemical Properties

white to light yellow crystal powde

Uses

An surgical antiseptic.

Uses

2,4-Dichlorobenzyl alcohol is an antiseptic found in commercially available throat lozenges. Also used deactivate Respiratory syncytial virus and SARS-Cov.

Definition

ChEBI: A member of the class of benzyl alcohols that is benzyl alcohol in which the hydrogens at positions 2 and 4 are replaced by chlorines.

General Description

2,4-Dichlorobenzyl alcohol is a constituent of commercially available lozenges for acute sore throat caused by upper respiratory tract infections.

Mechanism of action

In-vitro evidence has demonstrated the virucidal effect of Amylmetacresol (AMC) and 2,4-dichlorobenzyl alcohol (DCBA) on a number of viruses associated with the common cold; a reduction in viral load is believed to have benefits in reducing the symptoms. The local anesthetic action of AMC/DCBA throat lozenges, a combination of the potent channel blocker – AMC and the reduced potency for sodium channel blockade DCBA – attenuate the effects of AMC, possibly as a result of competitive binding, which acts on a sodium channel blocker, and may be effective in relieving symptoms due to inflammation. Therefore, AMC/DCBA throat lozenge is thought to represent a useful option to meet patients' needs and avoid unnecessary prescription of antibiotics[1].

Clinical Use

Amylmetacresol and 2,4-dichlorobenzyl alcohol throat lozenges have been marketed in many countries worldwide for pain relief in acute sore throat. Amylmetacresol and 2,4-dichlorobenzyl alcohol throat lozenges have been shown to be safe and efficient in relieving of acute sore throat symptoms, and it produces an immediate symptomatic relief. Local symptomatic pain relief plays an important role in managing acute sore throat[1-2].

Side effects

COMMON SIDE EFFECTS: Difficulty in breathing, Tongue soreness, Hypersensitivity reactions, Swelling of the face, Tongue, Throat and Neck.
