Medorphan (Dextromethorphan Hydrobromide)

Dextromethorphan acts as a non‑competitive antagonist of NMDA receptors and an agonist at sigma‑1 receptors in the brainstem’s medullary cough centre. This dual action reduces excitatory signalling that triggers the cough reflex, thereby suppressing cough without significant analgesic or sedative effects at normal doses.

The appropriate dose of Medorphan is determined by a qualified healthcare professional based on the patient’s age, weight, and clinical condition. OTC labeling typically advises adults to take the recommended amount every 4‑6 hours, not exceeding the maximum daily limit, but exact dosing should follow the prescriber’s instructions.

Safety data for dextromethorphan during pregnancy and lactation are limited. It should only be used if the potential benefit justifies any possible risk to the fetus or infant. Pregnant or nursing individuals should consult their healthcare provider before taking Medorphan.

To order Medorphan, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request verification of trade or institutional credentials. The sales team then replies with pricing, availability, shipping details and any necessary import documentation.

The primary alternative to dextromethorphan‑based products is codeine, an opioid cough suppressant. Medorphan offers cough relief without the opioid‑related risks of dependence, respiratory depression, or constipation. However, dextromethorphan can interact with serotonergic drugs, whereas codeine carries a higher potential for abuse and stricter regulatory controls.

Medorphan should be stored at room temperature below 25 °C, in its original packaging, and protected from moisture and direct sunlight. Keep the product out of reach of children and do not use it after the expiry date printed on the label.

Medorphan is taken orally, usually as a tablet or liquid preparation. The dose is swallowed with a glass of water and may be repeated at intervals recommended by the prescriber, typically every 4‑6 hours, without exceeding the maximum daily amount.

Serious adverse reactions, although rare, include allergic responses such as rash, swelling, or anaphylaxis, serotonin syndrome when combined with serotonergic agents, and hallucinations or other psychotic symptoms. If any of these occur, discontinue use immediately and seek medical attention.

Medorphan should be avoided in children under two years of age, individuals taking monoamine oxidase inhibitors (MAOIs), and patients with a known hypersensitivity to dextromethorphan or any excipients in the formulation. Caution is also advised for those with severe hepatic impairment.
