Angina pectoris
25-50 mg PO twice daily
Hepatic impairment: Contraindicated in severe liver impairment
Child Dose
Safety and efficacy not established
Renal Dose
Renal impairment: No dosage adjustments necessary
Administration
Should be taken with food.
Contra Indications
Hypersensitivity; severe chronic heart failure, bronchial asthma or related bronchospastic conditions; severe hepatic impairment. Patients with NYHA class IV cardiac failure, 2nd or 3rd ° AV block, sick sinus syndrome (unless a permanent pacemaker is in place), cardiogenic shock or severe bradycardia. Lactation.
Precautions
Avoid abrupt withdrawal as it may precipitate thyroid storm or exacerbate hyperthyroidism. Liver injury; vascular disease, renal failures, suspected phaeochromocytoma and prinzmetal's variable angina; worsening cardiac failure or fluid retention during increase in dosage of carvedilol; diabetic patients. Pregnancy.
Lactation: Unknown whether drug is excreted in milk; not recommended
Pregnancy-Lactation
Pregnancy
Available data in pregnant women are insufficient to determine whether there are drug-associated risks of adverse developmental outcomes; there are risks to mother and fetus associated with poorly controlled hypertension in pregnancy; the use of beta blockers during third trimester of pregnancy may increase risk of hypotension, bradycardia, hypoglycemia, and respiratory depression in neonates; in animal reproduction studies, there was no evidence of adverse developmental outcomes at clinically relevant doses; observe newborns for symptoms of hypotension, bradycardia, hypoglycemia, and respiratory depression and manage accordingly
Hypertension in pregnancy increases maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section and post-partum hemorrhage); hypertension increases fetal risk for intrauterine growth restriction and intrauterine death; pregnant women with hypertension should be carefully monitored and managed accordingly
Lactation
There are no data on presence of carvedilol in human milk, effects on breastfed infant, or on milk production; drug is present in the milk of lactating rats; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from treatment or from underlying maternal condition
Interactions
Decreased serum levels w/ rifampicin. Combination w/ Ca channel blockers (e.g. verapamil and diltiazem) can lead to bradycardia and myocardial depression. Potentiates insulin-induced hypoglycaemic action. May increase hypoglycaemic effects of antidiabetic agents. Increased risk of bradycardia w/ digoxin. Increased risk of hypotension and bradycardia w/ reserpine, MAOIs, clonidine. May increase ciclosporin concentrations. Concurrent use w/ ether, cyclopropane, trichloroethylene may increase the risk of hypotension and heart failure.
Side Effects
Side effects of Carvedilol :
>10%
Dizziness (2-32%), Fatigue (4-24%), Hypotension (9-20%), Weight gain (10-12%), Hyperglycemia (5-12%), Diarrhea (1-12%)
1-10%
Bradycardia (2-10%), Nausea (2-9%), Cough (5-8%), Headache (5-8%), Atrioventricular block, edema (1-7%), Angina (1-6%), Hpercholesterolemia (1-4%), Hypertriglyceredemia (1%), Vomiting (1-6%), Dyspnea (>3%), Syncope (3%), Rhinitis (2%)
Frequency Not Defined
Hypertension, Palpitations, Insomnia, Somnolence, Skin rash, Hepatotoxicity, Impotence, Bronchospasm, Rales, Depression, Decreased exercise tolerance, Raynaud phenomenon, Increased triglyceride levels and insulin resistance with decreased high-density lipoprotein (HDL) levels
Mode of Action
Carvedilol is a nonselective beta-adrenoreceptor and alpha-adrenergic blocking activity. It exerts antihypertensive effect partly by reducing total peripheral resistance and vasodilation.
