Noscapine Hydrochloride Aurobindo (Noscapine Hydrochloride)

Noscapine Hydrochloride is an antitussive that acts on the central cough reflex pathway.

• Acute cough: reduces the frequency and intensity of sudden coughing episodes.
• Chronic cough: helps control persistent coughing that lasts for weeks.
• Cough associated with respiratory infections: alleviates irritation‑driven cough during viral or bacterial upper‑respiratory tract infections.

• Noscapine Hydrochloride suppresses the cough reflex primarily through a central action in the medullary cough center. While the exact molecular target is not fully defined, it is believed to modulate neuronal excitability and inhibit the transmission of cough‑inducing signals, resulting in reduced cough frequency without significant opioid‑type effects.

Adverse reactions to Noscapine Hydrochloride are generally mild, but monitoring is advised.

Common Side Effects

• Nausea: mild stomach upset.
• Dizziness: transient light‑headedness.
• Fatigue: feeling unusually tired.
• Headache: mild to moderate pain.
• Gastrointestinal discomfort: mild abdominal cramping.
• Rash: mild skin irritation.

Serious or Rare Side Effects

• Allergic reaction: swelling, hives, or difficulty breathing.
• Hepatic dysfunction: elevated liver enzymes.
• Hematologic changes: unexplained bruising or bleeding.
• Severe dizziness: persistent vertigo.
• Cardiac arrhythmia: irregular heartbeat.
• Anaphylaxis: rapid onset of severe allergic symptoms.

Before using Noscapine Hydrochloride, consider the following safety measures.

• Pregnancy: consult a healthcare professional; safety data are limited.
• Breastfeeding: discuss potential risks with a physician.
• Liver disease: use with caution; monitor hepatic function.
• Renal impairment: dose adjustment may be required.
• Concomitant CNS depressants: monitor for additive sedation.
• Store at ambient temperature: keep below 25°C, protect from moisture and direct sunlight.

Noscapine Hydrochloride may interact with other medicines; review the following categories.

Major Interactions (Avoid)

• MAO inhibitors: risk of enhanced central nervous system effects.
• Opioid cough suppressants: potential additive sedation.

Moderate Interactions (Monitor Closely)

• Antihistamines: may increase drowsiness.
• Benzodiazepines: monitor for excessive sedation.
• Alcohol: can potentiate CNS depression.
• CYP450 substrates: possible alteration of metabolism.
• Herbal supplements (e.g., St. John’s wort): may affect drug levels.
