Dextromethorphan is a widely used active ingredient in various over-the-counter (OTC) cough medicines, providing effective relief for persistent coughs. As a cough suppressant, dextromethorphan works by affecting the brain's cough center, reducing the frequency and severity of coughing episodes. With its long history of use and established safety profile, dextromethorphan remains a popular choice for managing coughs associated with respiratory infections, allergies, and other conditions.
The use of dextromethorphan in cough medicines has been extensively studied, with numerous clinical trials demonstrating its efficacy in reducing cough frequency and severity. According to the American Academy of Pediatrics, dextromethorphan is a commonly used ingredient in pediatric cough medicines, providing effective relief for children with persistent coughs. Additionally, the National Institute of Allergy and Infectious Diseases notes that dextromethorphan can be used to manage coughs associated with respiratory infections, such as bronchitis and pneumonia.
How Dextromethorphan Works
Dextromethorphan is a non-opioid cough suppressant that works by blocking the action of glutamate and aspartate, two neurotransmitters involved in the transmission of cough signals to the brain. By inhibiting the release of these neurotransmitters, dextromethorphan reduces the brain's perception of cough stimuli, leading to a decrease in cough frequency and severity. This mechanism of action makes dextromethorphan an effective treatment for coughs associated with various conditions, including respiratory infections, allergies, and postnasal drip.
