Inderal

Propranolol Hydrochloride, the active ingredient in Inderal, is a beta blocker presented as an oral tablet for oral use. It reduces heart rate, myocardial contractility and blood pressure and is used in adults with hypertension, angina, arrhythmias, migraine prophylaxis and essential tremor.

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

Inderal, a non‑selective beta‑adrenergic antagonist, is employed across several cardiovascular and neurological conditions.

- Hypertension: lowers systolic and diastolic pressure to reduce cardiovascular risk. - Angina pectoris: decreases myocardial oxygen demand, relieving chest pain. - Myocardial infarction prophylaxis: reduces recurrence of heart attacks after an initial event. - Arrhythmias: stabilises abnormal heart rhythms by slowing conduction. - Migraine prophylaxis: prevents migraine attacks by modulating vascular tone. - Essential tremor: diminishes tremor amplitude in patients with this movement disorder.

Adverse reactions may vary in frequency and severity.

Common Side Effects: - Fatigue or drowsiness - Dizziness, especially on standing - Cold extremities or reduced peripheral circulation - Gastrointestinal upset such as nausea or abdominal cramps - Sleep disturbances, including vivid dreams - Mild bronchospasm in susceptible individuals

Serious or Rare Side Effects: - Severe bradycardia or heart block - Hypotension leading to syncope - Exacerbation of asthma or chronic obstructive pulmonary disease - Depressive mood changes or suicidal thoughts - Masking of hypoglycaemia symptoms in diabetic patients - Allergic reactions such as rash, angioedema, or anaphylaxis

Before initiating therapy, consider patient‑specific factors and monitor for adverse events.

- Cardiovascular disease: assess baseline heart rate and blood pressure. - Respiratory conditions: avoid in uncontrolled asthma or severe COPD. - Diabetes: monitor blood glucose as symptoms of hypoglycaemia may be blunted. - Thyroid disorders: use caution in hyperthyroidism due to potential for exaggerated heart rate changes. - Concomitant depression: observe for mood alterations. - Store at ambient temperature below 25°C: keep in the original container, protect from moisture and direct sunlight.

Propranolol may alter the pharmacokinetics or pharmacodynamics of several agents.

Major Interactions (Avoid): - Calcium channel blockers (e.g., verapamil, diltiazem): risk of profound bradycardia and AV block. - Anti‑arrhythmic drugs (e.g., amiodarone, flecainide): additive conduction slowing. - Non‑selective β‑blockers combined with other β‑blockers: excessive β‑blockade.

Moderate Interactions (Monitor Closely): - Antidiabetic agents (insulin, sulfonylureas): may potentiate hypoglycaemia. - NSAIDs and selective COX‑2 inhibitors: can attenuate antihypertensive effect. - Antidepressants (e.g., SSRIs, tricyclics): may increase plasma propranolol levels. - Antithyroid drugs: monitor thyroid function tests.
