Propenol SR 40mg Tablet 15s

Propenol Sr 40mg Tablet 15s contains propranolol and is used to treat high blood pressure (hypertension), certain heart rhythm disorders, angina (chest pain), migraine prevention, anxiety symptoms, and other cardiovascular conditions. High blood pressure occurs when the force of blood against artery walls remains persistently elevated, increasing the risk of heart attack, stroke, and kidney disease.

Propranolol works by blocking beta-adrenergic receptors in the heart and blood vessels, reducing heart rate and blood pressure. Propenol Sr 40mg Tablet 15s/Propranolol may be used alone or in combination with other medicines, depending on the condition being treated and the patient's overall cardiovascular risk profile.

Propenol Sr 40mg Tablet 15s contains propranolol, a non-selective beta-adrenergic blocker used to manage various cardiovascular and neurological conditions. It works by blocking both beta-1 receptors (primarily found in the heart) and beta-2 receptors (found in the lungs and blood vessels). By doing so, it slows the heart rate, reduces the force of heart contractions, and lowers blood pressure.

In hypertension, propranolol decreases cardiac output and suppresses renin release from the kidneys, which contributes to blood pressure reduction. In angina, it reduces myocardial oxygen demand by slowing the heart and lowering contractility. For arrhythmias, it stabilises the heart rhythm by controlling excessive sympathetic stimulation.

Propranolol is also widely used in migraine prevention and performance-related anxiety. In migraine, it stabilises vascular tone and reduces the frequency of attacks. In anxiety, particularly situational anxiety such as public speaking, it reduces physical symptoms like rapid heartbeat, tremors, and sweating.

Unlike selective beta-blockers, propranolol affects both heart and lung receptors, so caution is required in patients with asthma or chronic obstructive pulmonary disease (COPD). The medicine is metabolised in the liver and excreted through the kidneys. Patients with hepatic impairment may require dose adjustment.

The onset of action varies depending on the indication. For blood pressure and angina, therapeutic effects develop over several days. For anxiety symptoms, effects may be noticed within an hour. When taken as prescribed, Propenol Sr 40mg Tablet 15s/Propranolol is an effective and versatile medicine for long-term cardiovascular and neurological management.

Hypertension (High Blood Pressure)

Helps lower blood pressure and reduce cardiovascular risk.

Angina Pectoris

Reduces chest pain by decreasing heart workload and oxygen demand.

Cardiac Arrhythmias

Controls abnormal heart rhythms such as atrial fibrillation or supraventricular tachycardia.

Migraine Prevention

Reduces the frequency and severity of migraine attacks.

Anxiety (Performance or Situational)

Controls physical symptoms such as tremors and rapid heartbeat.

Post-Myocardial Infarction

Improves survival and reduces recurrence risk after a heart attack.

Hyperthyroidism

Controls symptoms such as palpitations and tremors.

Effective Blood Pressure Control

Reduces sustained hypertension and protects vital organs from long-term damage.

Heart Rate Regulation

Slows excessive heart rate and improves rhythm stability.

Migraine Prevention

Decreases the frequency and severity of migraine episodes.

Anxiety Symptom Relief

Controls physical manifestations of anxiety without sedation.

Post-Heart Attack Protection

Reduces risk of recurrent cardiovascular events.

Wide Clinical Utility

Useful across cardiovascular, neurological, and endocrine conditions.

When taken as prescribed, Propenol Sr 40mg Tablet 15s/Propranolol is generally well tolerated. Side effects are often mild and improve as the body adapts.

Common Side Effects

• Fatigue and Weakness: Reduced heart rate may cause tiredness, especially during early treatment.

• Cold Hands and Feet: Due to reduced peripheral circulation.

• Dizziness: Particularly when standing up quickly (orthostatic hypotension).

• Nausea or Mild Stomach Upset: Occasional digestive discomfort.

Uncommon Side Effects

• Bradycardia: Slower than normal heart rate.

• Sleep Disturbances: Vivid dreams or insomnia.

• Shortness of Breath: More likely in individuals with underlying respiratory disease.

• Depression or Mood Changes: Rare but possible with long-term use.

Serious Side Effects (Require Immediate Medical Attention)

• Severe Bradycardia or Heart Block: Marked slowing of the heart.

• Severe Hypotension: Fainting or collapse.

• Bronchospasm: Wheezing or difficulty breathing, especially in asthma patients.

• Allergic Reactions: Rash, swelling of the face or throat, difficulty swallowing.

Propenol Sr 40mg Tablet 15s/Propranolol should be taken exactly as prescribed. The dose varies depending on the condition being treated. It is usually taken one to three times daily. For anxiety, it may be taken 30 to 60 minutes before the stressful event.

Tablets should be swallowed whole with water and may be taken with or without food. Taking it consistently at the same time each day helps maintain stable blood levels. Do not stop abruptly without medical advice.

• Consistent Dosing: Take at regular intervals daily for steady cardiovascular control.

• Do Not Stop Suddenly: Abrupt withdrawal may cause rebound hypertension, angina, or arrhythmia.

• Monitor Heart Rate: Report pulse below 50 - 55 bpm or symptoms of fainting.

• Asthma Precaution: Inform your doctor if you have asthma, COPD, or breathing difficulty.

• Diabetes Monitoring: May mask symptoms of hypoglycaemia, such as a rapid heartbeat.

• Regular Check-ups: Periodic blood pressure and heart rate monitoring are essential.

• Stress Management: Combine with relaxation techniques in anxiety management.

Although Propenol Sr 40mg Tablet 15s/Propranolol can be taken with or without food, certain dietary factors may influence its effectiveness or increase the likelihood of side effects. Lifestyle habits, including alcohol intake and dietary sodium consumption, can significantly impact blood pressure control and overall cardiovascular outcomes.

• Alcohol (High): Increases the risk of dizziness and hypotension.

• Caffeine (Moderate): May reduce effectiveness in anxiety control.

• High-Sodium Diet (High): Reduces blood pressure-lowering benefits.

• Grapefruit (Low-Moderate): May alter liver metabolism in some individuals.

• Large Meals (Low): May slightly delay absorption, but not clinically significant.

Propenol Sr 40mg Tablet 15s/Propranolol can interact with several medicines that influence heart rate, blood pressure, or autonomic regulation. These interactions may increase the risk of excessive bradycardia, hypotension, or conduction abnormalities.

• Calcium Channel Blockers (High): Verapamil or diltiazem may cause severe bradycardia or heart block.

• Antiarrhythmics (High): Amiodarone and digoxin increase the risk of conduction disturbances.

• Insulin and Oral Antidiabetics (Moderate): Mask hypoglycaemia warning signs.

• NSAIDs (Moderate): May reduce antihypertensive effect.

• Clonidine (High): Sudden withdrawal increases the risk of rebound hypertension.

• Anaesthetics (Moderate): May enhance hypotensive effects during surgery.

Propenol Sr 40mg Tablet 15s/Propranolol should be prescribed cautiously in patients with certain pre-existing medical conditions. Because it blocks both beta-1 and beta-2 receptors, its systemic effects can influence respiratory, cardiovascular, metabolic, and hepatic function.

• Asthma or COPD (High): Risk of bronchospasm due to beta-2 blockade.

• Bradycardia or Heart Block (High): May worsen conduction abnormalities.

• Diabetes (Moderate): Masks hypoglycaemia symptoms.

• Peripheral Vascular Disease (Moderate): May worsen cold extremities.

• Depression (Low-Moderate): May aggravate mood symptoms.

• Severe Liver Disease (Moderate-High): Impaired metabolism may increase drug levels.

If you miss a dose, take it as soon as you remember, unless it is nearly time for the next scheduled dose. Skip the missed dose if close to the next one. Do not double the dose. Missing doses may reduce blood pressure control or trigger angina or arrhythmia symptoms.
