5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Throat Preparations; Antiseptics;

ATC Code: R02AA03 Dichlorobenzyl alcohol.

Mechanism of action

2,4-Dichlorobenzyl alcohol and amylmetacresol are antiseptics and possess antibacterial, antifungal and antiviral properties. Both AMC and DCBA also reversibly block depolarisation-induced ion channels in a similar way to local anaesthetics. When the two active agents are combined, a synergistic antibacterial action is observed leading to the reduced combined dose used in Strepsils lozenges.

Ascorbic acid and sodium ascorbate provide a source of Vitamin C, which may be beneficial during infection when Vitamin C levels are believed to fall.

Clinical efficacy and safety

Evidence of an analgesic effect for Strepsils in reducing throat soreness, providing pain relief and relief from difficulty in swallowing has been demonstrated to clinical studies with an onset in 5 minutes which lasts for up to 2 hours. Significantly more relief than nonmedical lozenge was also demonstrated for up to 3 days treatment.

Strepsils lozenge have also been shown to significantly decrease postoperative throat soreness and hoarseness 20 minutes and 24 hours after intubation.

A study in children (6-16 years) with acute and recurring chronic sore throat demonstrates a reduction in subjective and objective signs of sore throat over 3 days.

Strepsils Orange with Vitamin C lozenge base has a demulcent action providing throat soothing.
