Indications Bisopro, a highly selective β 1 ​ blocker, is indicated for the treatment of: 

• Hypertension (High blood pressure) 
• Angina (Chest pain) 
• Moderate to severe heart failure
• Note: It is not recommended for the emergency treatment of hypertensive crises.

Pharmacology Bisoprolol Fumarate is the most selective β 1 ​ blocker, primarily targeting β 1 ​ adrenergic receptors in the heart and vascular smooth muscle. This action reduces heart rate and cardiac output, leading to a decrease in arterial hypertension. Unlike non-selective β -blockers, Bisoprolol does not adversely affect the cholesterol fraction, including HDL -cholesterol, in long-term therapy. Its elimination half-life is 10 − 12 hours, supporting once-daily dosing. 

Dosage & Administration (Adults) The dose must be individualized. 

• Starting Dose: 5 mg once daily (alone or added to a diuretic). 
• Dose Titration: If the response is inadequate, the dose may be increased to 10 mg and then, if necessary, to 20 mg once daily. Doses are increased at 2 -week intervals. 
• Maximum Dose: Increasing the dose beyond 20 mg once daily provides minimal additional benefit. 

Special Populations:

• Renal or Hepatic Impairment: Initial daily dose should be 5  mg . Titration must be used with caution due to the possibility of drug accumulation. 
• Geriatrics: Dose adjustment is usually unnecessary, unless significant renal or hepatic dysfunction is present. 
• Children: Safety and effectiveness have not been established. 

Contraindications Do not use Bisopro in patients with: 

• Cardiogenic shock
• Overt heart failure
• Second or third-degree A-V block
• Right ventricular failure secondary to pulmonary hypertension 
• Sinus bradycardia

Side Effects Side effects are primarily related to CNS depression and may include: 

• Fatigue, dizziness, headache 
• Disturbances of the gut (nausea, vomiting, diarrhea, constipation, or abdominal pain) 
• Cold or numb extremities 
• Muscle weakness or cramps 
• Slower than normal heart rate ( bradycardia ) 
• Breathing difficulties ( bronchospasm ) in people with asthma or COPD . 

Interactions

• Other $\beta$ -blockers: Should not be combined. 
• Calcium Channel Blockers (e.g., Verapamil, Diltiazem) and Antiarrhythmic Agents (e.g., Disopyramide): Concurrent use may lead to severe hypotension, bradycardia, and cardiac failure. 
• Clonidine: The β -blocker should be withdrawn several days before discontinuing clonidine to avoid rebound hypertension. 

Therapeutic Class: Anti adrenergic agent ( Beta blockers ), Beta-adrenoceptor blocking drugs .
