INDERAL F 10 TABLET

🧠💊 Propranolol 40mg + Flunarizine 10mg Tablet: A Dual-Action Solution for Migraine and More

The combination of Propranolol 40mg and Flunarizine 10mg is a widely used medication in the prevention of migraine headaches, particularly in patients who suffer from frequent, chronic, or disabling attacks. This fixed-dose combination targets migraine through two distinct mechanisms—beta-blockade and calcium channel modulation—offering enhanced efficacy compared to monotherapy.

🔬 Mechanism of Action

This combination tablet works via a dual pharmacological pathway:

• Propranolol (40mg) is a non-selective beta-blocker. It reduces the frequency and intensity of migraines by:

  • Lowering blood pressure and heart rate

  • Reducing the excitability of neurons involved in migraine initiation

  • Stabilizing vascular tone in the brain

• Flunarizine (10mg) is a calcium channel blocker with antihistaminic properties. It prevents migraines by:

  • Reducing calcium influx in smooth muscle and neuronal cells

  • Improving cerebral blood flow

  • Decreasing migraine-associated neuronal hyperexcitability

Together, they provide synergistic protection against migraine triggers and help in reducing the severity and duration of migraine attacks.

📌 Indications and Uses

This combination tablet is primarily used for:

• Prophylaxis of migraine headaches, especially when episodes are frequent or severe

• Vascular headaches and tension-type headaches

• Sometimes used off-label for vestibular disorders (e.g., vertigo associated with migraine)

⚠️ This tablet is not for acute migraine relief. It is a preventive therapy meant to reduce the number and intensity of attacks over time.

💊 Dosage and Administration

• The usual adult dose is one tablet once daily, usually at bedtime to minimize daytime drowsiness (due to flunarizine).

• Dose adjustments should be made only under medical supervision.

• Effects may take 2–4 weeks to become noticeable.

It is important to use this medication consistently, as missing doses can reduce its preventive benefits.

⚠️ Precautions and Warnings

• Asthma/COPD: Avoid due to propranolol’s bronchoconstrictive effects.

• Depression: Flunarizine may worsen mood in susceptible individuals—use with caution.

• Bradycardia or heart block: Propranolol can exacerbate these conditions.

• Liver disease: Use cautiously as flunarizine is metabolized by the liver.

• Pregnancy and breastfeeding: Use only if clearly necessary under doctor’s advice.

🤒 Side Effects

Common side effects:

• Drowsiness or fatigue (flunarizine)

• Dizziness or low blood pressure

• Weight gain and increased appetite

• Cold hands and feet (propranolol)

• Sleep disturbances or vivid dreams

Serious (but rare):

• Depression or mood changes

• Parkinsonism or extrapyramidal symptoms (especially with long-term flunarizine use)

• Heart rhythm abnormalities

• Allergic reactions

If any severe or persistent symptoms occur, seek medical attention promptly.

---

🔄 Drug Interactions

• CNS depressants (e.g., alcohol, sedatives): May enhance drowsiness.

• Other antihypertensives or calcium channel blockers: Increased risk of hypotension or bradycardia.

• Antidepressants and antiepileptics: Use with caution due to additive CNS effects.

---

🧊 Storage Guidelines

• Store at room temperature (15–30°C)

• Keep away from light and moisture

• Out of reach of children
