Therefore, levothyroxine should be taken on a consistent schedule with regard to time of day and relation to meals to avoid large fluctuations in blood levels, which may alter its effects. In addition, absorption of levothyroxine may be decreased and/or delayed by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, calcium fortified juices and grapefruit or grapefruit juice. These foods should be avoided within several hours of dosing if possible.

Patients should be observed for signs of bradycardia or heart block, particularly when one agent is added to pre-existing treatment with the other. Of the 1,156 subjects randomized to COREG in a long-term, placebo-controlled trial in severe heart failure, 47% (547) were aged 65 years or older, and 15% (174) were aged 75years or older. Rarely, use of carvedilol in patients with heart failure has resulted in deterioration of renal function. Patients at risk appear to be those with low blood pressure (systolic blood pressure less than 100 mm Hg), ischemic heart disease and diffuse vascular disease, and/or underlying renal insufficiency.
Left Ventricular Dysfunction Following Myocardial Infarction
Bradycardia, hypotension, worsening heart failure/fluid retention may occur. In each trial, there was a primary end point, either progression of heart failure (1 U.S. trial) or exercise tolerance (2 U.S. trials meeting enrollment goals and the Australia‑New Zealand trial). There were many secondary end points specified in these trials, including NYHA classification, patient and physician global assessments, and cardiovascular hospitalization.
- You should not take Coreg if you have asthma, bronchitis, emphysema, severe liver disease, or a serious heart condition such as heart block, “sick sinus syndrome,” or slow heart rate (unless you have a pacemaker).
- Prior to initiation of COREG, it is recommended that fluid retention be minimized.
- The metabolites of carvedilol are excreted primarily via the bile into the feces.
- Amiodarone and its metabolite desethyl amiodarone, inhibitors of CYP2C9, and P- glycoprotein increased concentrations of the S(-)-enantiomer of carvedilol by at least 2 fold see Clinical Pharmacology (12.5).
Dosage Forms and Strengths
Coreg is only part of a complete treatment program that may also include diet, exercise, and weight control. Follow all directions on your prescription label and read all medication guides or instruction sheets. Coreg is also used after a heart attack that has caused your heart not to pump as well.

Amiodarone and its metabolite desethyl amiodarone, inhibitors of CYP2C9, and Pglycoprotein increased concentrations of the S(-)-enantiomer of carvedilol by at least 2 fold see CLINICAL PHARMACOLOGY. Four U.S. multicenter, double-blind, placebo-controlled trials enrolled 1,094 subjects (696 randomized to carvedilol) with NYHA class II-III heart failure and ejection fraction less than or equal to 0.35. An Australia-New Zealand double-blind, placebo-controlled trial enrolled 415 subjects (half randomized to carvedilol) with less severe heart failure. All protocols excluded subjects expected to undergo cardiac transplantation during the 7.5 to 15 months of double-blind follow-up. All randomized subjects had tolerated a 2-week course on carvedilol 6.25 mg twice daily.
- Do not abruptly stop taking COREG®, as it may lead to acute exacerbation of coronary artery disease upon cessation of therapy.Bradycardia, hypotension, worsening heart failure/fluid retention may occur.
- Diltiazem is used to treat high blood pressure, angina and certain heart rhythm disorders.
- The following adverse events not described above were reported as possibly or probably related to COREG in worldwide open or controlled trials with COREG in subjects with hypertension or heart failure.
- Thus, this trial extends the time over which carvedilol manifests benefits on survival in heart failure, but it is not evidence that carvedilol improves outcome over the formulation of metoprolol (TOPROL-XL) with benefits in heart failure.
- In about 30% of subjects, the dose of cyclosporine had to be reduced in order to maintain cyclosporine concentrations within the therapeutic range, while in the remainder no adjustment was needed.
- Carvedilol is metabolized primarily by aromatic ring oxidation and glucuronidation.
Drug Interactions between Coreg and Synthroid
Compared with healthy subjects, patients with severe liver impairment (cirrhosis) exhibit a 4- to 7-fold increase in carvedilol levels. Carvedilol is contraindicated in patients with severe liver impairment. Neonates synthroid uso of women with hypertension who are treated with beta-blockers during the third trimester of pregnancy may be at increased risk for hypotension, bradycardia, hypoglycemia, and respiratory depression.
Death was not a pre-specified end point in any trial but was analyzed in all trials. Overall, in these 4 U.S. trials, mortality was reduced, nominally significantly so in 2 trials. The basis for the beneficial effects of COREG in heart failure is not established. Of the 975 subjects with myocardial infarction randomized to COREG in the CAPRICORN trial, 48% (468) were aged 65 years or older, and 11% (111) were aged 75 years or older.
- These foods should be avoided within several hours of dosing if possible.
- In some cases, this may be harmful and your doctor may advise you to avoid certain foods.
- In a pharmacokinetic trial conducted in 8 healthy male subjects, rifampin (600 mg daily for 12 days) decreased the AUC and Cmax of carvedilol by about 70% see DRUG INTERACTIONS.
- In hypertensive patients with normal renal function, therapeutic doses of COREG decreased renal vascular resistance with no change in glomerular filtration rate or renal plasma flow.
- However, caution should be taken in the administration of carvedilol to patients suspected of having Prinzmetal’s variant angina.
- Using multivitamin with minerals together with levothyroxine may decrease the effects of levothyroxine.
COREG has little effect on plasma catecholamines, plasma aldosterone, or electrolyte levels, but it does significantly reduce plasma renin activity when given for at least 4 weeks. In patients with pheochromocytoma, an α-blocking agent should be initiated prior to the use of any β-blocking agent. Although carvedilol has both α- and β-blocking pharmacologic activities, there has been no experience with its use in this condition.
Clinical Pharmacology for Coreg
Median trial medication exposure was 6.3 months for both carvedilol and placebo subjects in the trials of mild‑to‑moderate heart failure and 10.4 months in the trial of subjects with severe heart failure. The adverse event profile of COREG observed in the long-term COMET trial was generally similar to that observed in the U.S. Table 1 shows adverse events reported in subjects with mild-to-moderate heart failure enrolled in U.S. placebo-controlled clinical trials, and with severe heart failure enrolled in the COPERNICUS trial. Shown are adverse events that occurred more frequently in drug-treated subjects than placebo-treated subjects with an incidence of greater than 3% in subjects treated with carvedilol regardless of causality.
The dosing recommendations should be followed closely and the dose should be lowered if any evidence of bronchospasm is observed during up-titration. Following oral administration, when postural hypotension has occurred, it has been transient and is uncommon when COREG is administered with food at the recommended starting dose and titration increments are closely followed see DOSAGE AND ADMINISTRATION. Two placebo-controlled trials compared the acute hemodynamic effects of COREG with baseline measurements in 59 and 49 subjects with NYHA class II-IV heart failure receiving diuretics, ACE inhibitors, and digitalis. In the CAPRICORN trial of survivors of an acute myocardial infarction, hypotension or postural hypotension occurred in 20.2% of subjects receiving COREG compared with 12.6% of placebo subjects. These events were a cause for discontinuation of therapy in 2.5% of subjects receiving COREG, compared with 0.2% of placebo subjects.
