Explanation:
- Some common cough syrups that contain alcohol include some formulations of NyQuil, ZzzQuil, and other nighttime cough or cough/cold syrups, among others.
- The ethyl alcohol is used in cough syrups and tonics for the cure of respiratory and cough related diseases. Because of its high solubility, ethanol is used in cough syrups and tonics. Note: Ethanol is naturally produced by the fermentation of sugars by yeasts or via petrochemical processes such as ethylene hydration.
- Alcohol in pharmaceutical products acts as a preservative and/or promotes sedation depending on the agents listed and the responsibility lies with the consumer of knowing what is in medications that are taken.
- Results: The ethanol percentage by volume (% v/v) in the test- ed syrups ranges from 0.102% to 2.576%. All five syrups studied comply with the FDA require- ment for drugs for adults and children >6 years since they do not contain more than 5% ethanol.
