BALMINIL DM : Mechanism of Action, Indications, uses, Administration, Side Effects

Dextromethorphan (DM) is a medication used as a cough suppressant. Here are the details regarding dextromethorphan's chemical formula, mechanism of action, indications, uses, administration, and side effects:

Chemical Formula:

The chemical formula for dextromethorphan is C18H25NO.

Mechanism of Action:

  • Dextromethorphan works by affecting the cough reflex in the brain. It is a non-opioid, non-narcotic agent that suppresses coughing.

  • While the exact mechanism of action is not fully understood, it is believed to involve the inhibition of the NMDA (N-methyl-D-aspartate) receptors in the brain. These receptors are involved in transmitting pain and cough signals.


  • Dextromethorphan is primarily indicated for the relief of cough due to various respiratory conditions, such as the common cold, bronchitis, and other upper respiratory tract infections.

  • It is not intended to treat the underlying cause of the cough but provides temporary relief by suppressing the cough reflex.


  • In addition to its use as a cough suppressant, dextromethorphan has been investigated for potential therapeutic effects in other conditions.

  • It has been studied for its potential use in neuropathic pain, fibromyalgia, and other chronic pain conditions. Dextromethorphan has also been researched for its potential antidepressant and neuroprotective properties. However, further research is needed to establish its efficacy in these areas.


  • Dextromethorphan is available in various formulations, including syrups, capsules, lozenges, and tablets.

  • The specific dosage and administration instructions may vary depending on the product and the individual's age and weight.

  • Generally, it is taken orally and should be administered according to the instructions provided by the healthcare professional or as directed on the packaging.

Side Effects:

  • While dextromethorphan is generally considered safe when used as directed, it can cause certain side effects. Common side effects may include dizziness, drowsiness, nausea, upset stomach, and constipation. These side effects are usually mild and temporary.

  • However, it's important to note that higher doses of dextromethorphan or misuse of the medication can lead to more severe side effects, including hallucinations, confusion, impaired coordination, rapid heartbeat, respiratory depression, and even overdose.

  • Misuse or combining dextromethorphan with other substances, such as alcohol or certain medications, can also increase the risk of adverse effects.

  • It is crucial to follow the recommended dosage and guidelines provided by healthcare professionals or the medication packaging.

  • If any concerning symptoms or side effects occur while taking dextromethorphan, it is important to seek medical advice.
