Tusq D Sugar Free Lozenges Uses, Dosage, Side Effects, Food Interaction and all others data.

Amylmetacresol is an antiseptic available in Canada over-the-counter in a number of lozenges for the treatment of sore throat and minor mouth infections , . Amylmetacresol is often combined with dichlorobenzyl alcohol and menthol in the commonly used sore throat lozenges, known as Strepsils .

The acute sore throat (pharyngitis) is one of the most common conditions for which children are seen in the primary care setting. Pharyngitis is normally caused by viruses and proves benign and self-limiting. Clinically proven, over-the-counter throat lozenges offer rapid and effective relief of acute sore throat symptoms, and are increasingly important in the management of this condition .

The mixture of amylmetacresol throat lozenge medications markedly reduces the infectivity of certain infectious viruses in the throat and in cough droplets, thus reducing opportunities for person-to-person transmission . In addition, it relieves symptoms of sore throat/irritation of the throat , .

Dextromethorphan suppresses the cough reflex by a direct action on the cough center in the medulla of the brain. Dextromethorphan shows high affinity binding to several regions of the brain, including the medullary cough center. This compound is an NMDA receptor antagonist and acts as a non-competitive channel blocker. It is one of the widely used antitussives, and is also used to study the involvement of glutamate receptors in neurotoxicity.

Dextromethorphan is an opioid-like molecule indicated in combination with other medication in the treatment of coughs and pseudobulbar affect. It has a moderate therapeutic window, as intoxication can occur at higher doses. Dextromethorphan has a moderate duration of action. Patients should be counselled regarding the risk of intoxication.

How Tusq D Sugar Free Lozenges works

The mechanism of virucidal action is not fully elucidated, however it is suggested that denaturation of external protein spikes, a pH-induced rearrangement of the tertiary structure of attachment proteins, or a selective effect on viral lipid membranes/protein–lipid interaction is responsible for this action .

Amylmetacresol is an antibacterial and antiviral agent, and blocks voltage-gated Na channels in a local anesthetic-like manner .

Dextromethorphan is an agonist of NMDA and sigma-1 receptors. It is also an antagonist of α3/β4 nicotinic receptors.[A10589] However, the mechanism by which dextromethorphan's receptor agonism and antagonism translates to a clinical effect is not well understood.
