Overview

What is Carvedilol?

Carvedilol is a nonselective β-adrenergic blocking agent with α-blocking activity. It is (±)-1-(Carbazol-4-yloxy)-3-[[2-(o-methoxyphenoxy)ethyl]amino]-2-propanol. Carvedilol is a racemic mixture with the following structure:

Carvedilol is a white to almost white crystalline powder with a molecular weight of 406.5 and a molecular formula of CHNO. It is freely soluble in dimethylsulfoxide; soluble in methylene chloride and methanol; sparingly soluble in 95% ethanol and isopropanol; slightly soluble in ethyl ether; and practically insoluble in water, gastric fluid (simulated, TS, pH 1.1), and intestinal fluid (simulated, TS without pancreatin, pH 7.5).

Each carvedilol tablet intended for oral administration contains 3.125 mg or 6.25 mg or 12.5 mg or 25 mg of carvedilol. In addition, each tablet contains the following inactive ingredients: colloidal silicon dioxide, crospovidone, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, povidone, talc, and titanium dioxide.

What are the available doses of Carvedilol?

The white to off-white, round, film-coated tablets are available in the following strengths: 3.125 mg– debossed with Z and 1, 6.25 mg–debossed with ZC40, 12.5 mg–debossed with ZC41 and 25 mg–debossed with ZC42.

What should I talk to my health care provider before I take Carvedilol?

How should I use Carvedilol?

Carvedilol tablets are indicated to reduce cardiovascular mortality in clinically stable patients who have survived the acute phase of a myocardial infarction and have a left ventricular ejection fraction of ≤40% (with or without symptomatic heart failure) [see

Carvedilol should be taken with food to slow the rate of absorption and reduce the incidence of orthostatic effects.

Severe bradycardia (unless permanent pacemaker in place) ()

Patients in cardiogenic shock or decompensated heart failure requiring the use of IV inotropic therapy. ()

What might happen if I take too much Carvedilol?

Overdosage may cause severe hypotension, bradycardia, cardiac insufficiency, cardiogenic shock, and cardiac arrest. Respiratory problems, bronchospasms, vomiting, lapses of consciousness, and generalized seizures may also occur.

The patient should be placed in a supine position and, where necessary, kept under observation and treated under intensive-care conditions. Gastric lavage or pharmacologically induced emesis may be used shortly after ingestion. The following agents may be administered:

for excessive bradycardia:

to support cardiovascular function:

If peripheral vasodilation dominates, it may be necessary to administer adrenaline or noradrenaline with continuous monitoring of circulatory conditions. For therapy-resistant bradycardia, pacemaker therapy should be performed. For bronchospasm, β-sympathomimetics (as aerosol or IV) or aminophylline IV should be given. In the event of seizures, slow IV injection of diazepam or clonazepam is recommended.

NOTE: In the event of severe intoxication where there are symptoms of shock, treatment with antidotes must be continued for a sufficiently long period of time consistent with the 7- to 10-hour half-life of carvedilol.

Cases of overdosage with carvedilol tablets alone or in combination with other drugs have been reported. Quantities ingested in some cases exceeded 1,000 milligrams. Symptoms experienced included low blood pressure and heart rate. Standard supportive treatment was provided and individuals recovered.

ID171

Patients with coronary artery disease, who are being treated with carvedilol tablets, should be advised against abrupt discontinuation of therapy. Severe exacerbation of angina and the occurrence of myocardial infarction and ventricular arrhythmias have been reported in angina patients following the abrupt discontinuation of therapy with β-blockers. The last 2 complications may occur with or without preceding exacerbation of the angina pectoris. As with other β-blockers, when discontinuation of carvedilol tablets is planned, the patients should be carefully observed and advised to limit physical activity to a minimum. Carvedilol tablets should be discontinued over 1 to 2 weeks whenever possible. If the angina worsens or acute coronary insufficiency develops, it is recommended that carvedilol tablets be promptly reinstituted, at least temporarily. Because coronary artery disease is common and may be unrecognized, it may be prudent not to discontinue therapy with carvedilol abruptly even in patients treated only for hypertension or heart failure.
