Bisoprolol Drug Information

Bisoprolol fumarate tablets are indicated in the management of hypertension. It may be used alone or in combination with other antihypertensive agents.

The dose of bisoprolol fumarate tablets must be individualized to the needs of the patient. The usual starting dose is 5 mg once daily. In some patients, 2.5 mg may be an appropriate starting dose (see Bronchospastic Disease in WARNINGS ). If the antihypertensive effect of 5 mg is inadequate, the dose may be increased to 10 mg and then, if necessary, to 20 mg once daily.

Patients with Renal or Hepatic Impairment In patients with hepatic impairment (hepatitis or cirrhosis) or renal dysfunction (creatinine clearance less than 40 mL/min), the initial daily dose should be 2.5 mg and caution should be used in dose-titration. Since limited data suggest that bisoprolol fumarate is not dialyzable, drug replacement is not necessary in patients undergoing dialysis. Geriatric Patients It is not necessary to adjust the dose in the elderly, unless there is also significant renal or hepatic dysfunction (see above and Geriatric Use in PRECAUTIONS ). Pediatric Patients There is no pediatric experience with bisoprolol fumarate tablets.

In addition, a variety of adverse effects have been reported with other beta-adrenergic blocking agents and should be considered potential adverse effects of bisoprolol fumarate tablets: Central Nervous System Reversible mental depression progressing to catatonia, hallucinations, an acute reversible syndrome characterized by disorientation to time and place, emotional lability, slightly clouded sensorium. Allergic Fever, combined with aching and sore throat, laryngospasm, respiratory distress. Hematologic Agranulocytosis, thrombocytopenia, thrombocytopenic purpura.

Gastrointestinal Mesenteric arterial thrombosis, ischemic colitis. Miscellaneous The oculomucocutaneous syndrome associated with the beta-blocker practolol has not been reported with bisoprolol fumarate tablets during investigational use or extensive foreign marketing experience.

Pregnancy In rats, bisoprolol fumarate was not teratogenic at doses up to 150 mg/kg/day which is 375 and 77 times the MRHD on the basis of body weight and body surface area, respectively. Bisoprolol fumarate was fetotoxic (increased late resorptions) at 50 mg/kg/day and maternotoxic (decreased food intake and body weight gain) at 150 mg/kg/day. The fetotoxicity in rats occurred at 125 times the MRHD on a body weight basis and 26 times the MRHD on the basis of body surface area.

The maternotoxicity occurred at 375 times the MRHD on a body weight basis and 77 times the MRHD on the basis of body surface area. In rabbits, bisoprolol fumarate was not teratogenic at doses up to 12.5 mg/kg/day, which is 31 and 12 times the MRHD based on body weight and body surface area, respectively, but was embryolethal (increased early resorptions) at 12.5 mg/kg/day. There are no adequate and well-controlled studies in pregnant women.

Bisoprolol fumarate tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Pediatric Use Safety and effectiveness in pediatric patients have not been established.

Bisoprolol fumarate tablets are contraindicated in patients with cardiogenic shock, overt cardiac failure, second or third degree AV block, and marked sinus bradycardia.

The most common signs expected with overdosage of a beta-blocker are bradycardia, hypotension, congestive heart failure, bronchospasm, and hypoglycemia. To date, a few cases of overdose (maximum: 2000 mg) with bisoprolol fumarate have been reported. Bradycardia and/or hypotension were noted.

Sympathomimetic agents were given in some cases, and all patients recovered. In general, if overdose occurs, bisoprolol fumarate tablets therapy should be stopped and supportive and symptomatic treatment should be provided. Limited data suggest that bisoprolol fumarate is not dialyzable.

Based on the expected pharmacologic actions and recommendations for other beta-blockers, the following general measures should be considered when clinically warranted: Bradycardia Administer IV atropine. If the response is inadequate, isoproterenol or another agent with positive chronotropic properties may be given cautiously. Under some circumstances, transvenous pacemaker insertion may be necessary.

Hypotension IV fluids and vasopressors should be administered. Intravenous glucagon may be useful. Heart Block (second or third degree) Patients should be carefully monitored and treated with isoproterenol infusion or transvenous cardiac pacemaker insertion, as appropriate.

Congestive Heart Failure Initiate conventional therapy (ie, digitalis, diuretics, inotropic agents, vasodilating agents). Bronchospasm Administer bronchodilator therapy such as isoproterenol and/or aminophylline. Hypoglycemia Administer IV glucose.
