Contraindications:

Cardiogenic shock, heart block (2nd, 3rd degree), sinus bradycardia, overt cardiac failure

Side Effects:

CNS: Catatonia, depression, dizziness, drowsiness, fatigue, hallucinations, headache, insomnia, lethargy, memory loss, mental changes, peripheral neuropathy, strange dreams, vertigo CV: Bradycardia, CHF, cold extremities, postural hypotension, profound hypotension, 2nd or 3rd degree heart block, ventricular dysrhythmias EENT:. Dry burning eyes, rhinitis, sinusitis, sore throat GI: Diarrhea, flatulence, gastric pain, gastritis, increased AST/ALT (1-2 times normal in 4%), ischemic colitis, mesenteric arterial thrombosis, nausea, vomiting GU: Decreased libido, impotence HEME: Purpura METAB: Azotemia, hyperglycemia, hyperkalemia, hypertriglyceridemia, hyperuricemia, increased hypoglycemic response to insulin MS: Arthralgia, joint pain RESP: Bronchospasm, cough, dyspnea, wheezing SKIN: Alopecia, fever, pruritus, rash, sweating MISC: Decreased exercise tolerance, edema, facial swelling, weight gain

Cautions:

Precautions:

Anesthesia/surgery (myocardial depression), avoid abrupt withdrawal; broncho-spastic airways, congestive heart failure, diabetes mellitus, hyperthyroidism/thyrotoxicosis (bisoprolol, unlike propranolol, does not decrease T3 levels), concurrent clonidine (discontinue bisoprolol severa days prior to withdrawal of clonidine), peripheral vascular disease, renal disease

Interaction:

Drugs

Adenosine: Additive bradycardia Alpha-1 adrenergic blockers:Potential enhanced first dose response [marked initial drop in blood pressure, particularly on standing (especially prazocin)]Amiodarone: Increased bradycardia effect of bisoprolol Antidiabetic: Reduced response to hypoglycemia (sweating persists) Barbiturates: Enhanced bisoprolol metabolism Cimetidine: Plasma levels of ß-blocker may be elevated Cocaine: Bisprolol potentiates cocaine-induced coronary vasoconstriction Contrast media: Increased risk for anaphylaxis Digoxin, digitoxin: Potentiation of bradycardia; additive prolongation of atrioventricular (AV) conduction timeDipyridamole: Additive bradycardia Disopyramide: Additive decreases in cardiac output Fluoxetine: Fluoxetine inhibits CYPD26, partially responsible for bisoprolol metabolism; increased ß-blocker effects Lidocaine: ß-blocker-induced reductions in cardiac output and hepatic blood flow may yield increased lidocaine concentrations Neostigmine: Additive bradycardia s Neuroleptics: Decreased bisoprolol metabolism; decreased neuroleptic metabolism NSAIDs: Reduced antihypertensive effect Physostigmine: Additive bradycardia Prazosin: Enhanced 1st-dose response to prazosin. Rifampin: Increases clearance by 51%, reduced ß-blocker effects Tacrine: Additive bradycardia Theophylline: Bisoprolol reduces clearance of theophylline; antagonistic pharmacodynamics

Warnings:

Adverse Effects:

Lactations:

Similar drug,atenolol frequently used in the third trimester for treatment of hypertension (many studies of efficacy and safety of atenolol in pregnancy-induced hypertension); long-term use has been associated with intrauterine growth retardation; excreted into breast milk; observe for signs of beta-blockade
