How Hydryllin DM Works?

Diphenhydramine and dextromethorphan are two active ingredients commonly found in Hydryllin DM Syrup. They have distinct modes of action:

Diphenhydramine: Diphenhydramine is an antihistamine with additional antitussive properties. Its mode of action involves:

  • Antihistamine Effect: Diphenhydramine works by blocking the effects of histamine, a chemical released during an allergic reaction. By binding to histamine receptors, particularly H1 receptors, it helps to reduce symptoms such as sneezing, itching, runny nose, and watery eyes associated with allergies.
  • Antitussive Effect: Diphenhydramine also acts as a cough suppressant by inhibiting the cough reflex in the brain. It works by reducing the sensitivity of the cough center, providing temporary relief from coughing.

Dextromethorphan: Dextromethorphan is a cough suppressant and belongs to a class of medications called antitussives. Its mode of action involves:

  • NMDA Receptor Antagonism: Dextromethorphan acts as a non-competitive antagonist of N-methyl-D-aspartate (NMDA) receptors in the brain. By blocking NMDA receptors, it reduces the transmission of cough signals in the central nervous system, resulting in decreased coughing.
  • Sigma-1 Receptor Agonism: Dextromethorphan also has an affinity for sigma-1 receptors, which are located in various regions of the brain. Activation of sigma-1 receptors may contribute to the antitussive effects of dextromethorphan, although the exact mechanism is not fully understood.
