Inderal

Propranolol, the active ingredient in Inderal, is a beta blocker presented as an oral dosage form for oral use. It treats hypertension, angina pectoris, cardiac arrhythmias, myocardial infarction prophylaxis, migraine prophylaxis, and essential tremor in adult patients.

GNH USA supplies Inderal as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Propranolol acts on the cardiovascular and nervous systems to control blood pressure, heart rhythm, and vascular tone. - Hypertension: lowers blood pressure by reducing heart rate, myocardial contractility, and renin release. - Angina pectoris: decreases myocardial oxygen demand, relieving chest pain. - Cardiac arrhythmias: stabilises abnormal heart rhythms by slowing conduction through the AV node. - Myocardial infarction prophylaxis: reduces risk of recurrent infarction by limiting cardiac workload. - Migraine prophylaxis: prevents migraine attacks through vascular stabilisation. - Essential tremor: diminishes tremor amplitude by dampening peripheral beta‑adrenergic activity.

Propranolol may cause a range of adverse reactions, from mild to serious.

Common Side Effects: - Fatigue or tiredness - Dizziness or light‑headedness - Cold hands and feet - Gastrointestinal upset (nausea, abdominal discomfort) - Sleep disturbances (insomnia or vivid dreams) - Mild bradycardia

Serious or Rare Side Effects: - Severe bradycardia or heart block - Marked hypotension - Bronchospasm, especially in asthmatic patients - Acute heart failure exacerbation - Masking of hypoglycaemia symptoms in diabetics - Depression or mood changes

Before prescribing propranolol, clinicians should evaluate patient‑specific factors and monitor for adverse outcomes. - Assess cardiovascular status: check baseline heart rate, blood pressure, and ECG. - Review respiratory history: avoid in uncontrolled asthma or severe COPD. - Monitor glucose control: patients with diabetes may experience masked hypoglycaemia. - Evaluate for depression: beta‑blockers can exacerbate mood disorders. - Adjust dose cautiously in renal or hepatic impairment. - Store at ambient temperature: keep in the original container, protect from moisture and light.

Propranolol interacts with several drug classes; careful management is required.

Major Interactions (Avoid): - Asthma or severe COPD medications: non‑selective β‑blockade may precipitate bronchospasm. - Calcium channel blockers (verapamil, diltiazem): increased risk of AV block and bradycardia. - Insulin or oral hypoglycaemic agents: may mask hypoglycaemia symptoms. - MAO inhibitors: can cause hypertensive crisis. - Other β‑blockers: additive cardiac depression.

Moderate Interactions (Monitor Closely): - Antihypertensives (ACE inhibitors, diuretics): may enhance hypotensive effect. - Digoxin: increased risk of bradyarrhythmias. - Antidepressants (SSRIs, tricyclics): potential for additive CNS effects. - NSAIDs: may reduce antihypertensive efficacy. - Antithyroid drugs: may alter thyroid hormone levels.
