Contra Indications

Patients with cardiogenic shock, overt cardiac failure, second or third degree AV block and marked sinus bradycardia.

Precautions

Impaired Renal or Hepatic Function. Lactation: excretion in milk unknown; use caution

Pregnancy-Lactation

Interactions

May potentiate AV conduction time and may increase negative inotropic effect w/ class I antiarrhythmic drugs (e.g. quinidine, disopyramide, propafenone). Concomitant catecholamine-depleting drugs (e.g. reserpine, guanethidine) may produce excessive sympathetic activity. May exacerbate rebound HTN upon discontinuance of clonidine treatment. Increased risk of bradycardia w/ digitalis glycosides. Reduced hypotensive effect w/ NSAIDs.

Adverse Effects

Side effects of Bisoprolol : 1-10% Dizziness (10%),Dyssomnia (8%-10%),Bradyarrhythmia (9%),Upper respiratory infection (5%),Diarrhea (4%),Rhinitis (4%),Arthralgia (3%),Cough (3%),Dyspnea (2%),Nausea (2%),Pharyngitis (2%),Sinusitis (2%),Vomiting (2%) <1% Cold extremities,Hypotension,Depression,Dyspepsia,Bronchospasm Frequency Not Defined Aggravate CHF,Decrease HDL,Hypertriglyceridemia,Mask symptoms of hypoglycemia,Decreased exercise tolerance,Raynaud's phenomenon,May increase triglyceride levels and insulin resistance

Mechanism of Action

Bisoprolol selectively and competitively blocks beta1-receptors but has little or no effect on beta2-receptors except at high doses.
