🔹 Levodropropizine + Chlorpheniramine

🧪 Components

1. Levodropropizine →

   • Peripheral antitussive

   • Suppresses dry cough without CNS depression.

2. Chlorpheniramine maleate →

   • First-generation antihistamine (H1 blocker)

   • Reduces allergic symptoms: runny nose, sneezing, watery eyes.

   • Has mild sedative effect.

🎯 Why this Combination?

• Many coughs are allergic + irritative in nature (e.g., allergic rhinitis, seasonal flu).

• Levodropropizine controls the cough reflex.

• Chlorpheniramine reduces allergy-related symptoms (sneezing, nasal drip) that often trigger cough.
  👉 Together: more effective relief in dry, allergic cough.

⚠️ Side Effects

  • Blurred vision (rare)

🚫 Precautions

• Avoid in productive cough (can trap mucus).

• Caution in:

  • Children <2 years

  • Elderly (due to sedation, confusion risk)

  • Patients with liver/kidney disease

• Avoid driving/operating machinery (sedation risk from chlorpheniramine).
