Product Description.:
KPI 241, CORGARD 80
tablet , blue , scored , round round
CORGARD (nadolol) is a synthetic nonselective beta-adrenergic receptor blocking agent designated chemically as 1-(tert-butylamino)-3-[(5,6,7,8-tetrahydro-cis-6,7-dihydroxy-1- naphthyl)oxy]-2-propanol.
Nadolol is a white crystalline powder. It is freely soluble in ethanol, soluble in hydrochloric acid, slightly soluble in water and in chloroform, and very slightly soluble in sodium hydroxide.
CORGARD (nadolol) is available for oral administration as 20 mg, 40 mg, and 80 mg tablets. Inactive ingredients: microcrystalline cellulose, colorant (FD&C Blue No. 2), corn starch, magnesium stearate, povidone (except 20 mg and 40 mg), and other ingredients.
INDICATIONS
Angina Pectoris
CORGARD (nadolol) is indicated for the long-term management of patients with angina pectoris.
Hypertension
CORGARD (nadolol) is indicated in the management of hypertension it may be used alone or in combination with other antihypertensive agents, especially thiazide-type diuretics.
SIDE EFFECTS
Most adverse effects have been mild and transient and have rarely required withdrawal of therapy.
Cardiovascular
Bradycardia with heart rates of less than 60 beats per minute occurs commonly, and heart rates below 40 beats per minute and/or symptomatic bradycardia were seen in about 2 of 100 patients. Symptoms of peripheral vascular insufficiency, usually of the Raynaud type, have occurred in approximately 2 of 100 patients. Cardiac failure, hypotension, and rhythm/conduction disturbances have each occurred in about 1 of 100 patients. Single instances of first degree and third degree heart block have been reported intensification of AV block is a known effect of beta-blockers
WARNINGS
Cardiac Failure
Sympathetic stimulation may be a vital component supporting circulatory function in patients with congestive heart failure, and its inhibition by beta-blockade may precipitate more severe failure. Although beta-blockers should be avoided in overt congestive heart failure, if necessary, they can be used with caution in patients with a history of failure who are well-compensated, usually with digitalis and diuretics. Beta-adrenergic blocking agents do not abolish the inotropic action of digitalis on heart muscle.
IN PATIENTS WITHOUT A HISTORY OF HEART FAILURE, continued use of beta- blockers can, in some cases, lead to cardiac failure. Therefore, at the first sign or symptom of heart failure, the patient should be digitalized and/or treated with diuretics, and the response observed closely, or nadolol should be discontinued (gradually, if possible).
