COREG CR (Page 10 of 11)

14.3 Hypertension

A double-blind, randomized, placebo-controlled, 8-week trial evaluated the blood pressure-lowering effects of COREG CR 20 mg, 40 mg, and 80 mg once daily in 338 subjects with essential hypertension (sitting diastolic blood pressure [DBP] greater than or equal to 90 and less than or equal to 109 mm Hg). Of 337 evaluable subjects, a total of 273 subjects (81%) completed the trial. Of the 64 (19%) subjects withdrawn from the trial, 10 (3%) were due to adverse events, 10 (3%) were due to lack of efficacy; the remaining 44 (13%) withdrew for other reasons. The mean age of the subjects was approximately 53 years, 66% were male, and the mean sitting systolic blood pressure (SBP) and DBP at baseline were 150 mm Hg and 99 mm Hg, respectively. Dose titration occurred at 2‑week intervals.

Statistically significant reductions in blood pressure as measured by 24‑hour ambulatory blood pressure monitoring (ABPM) were observed with each dose of COREG CR compared with placebo. Placebo-subtracted mean changes from baseline in mean SBP/DBP were ‑6.1/‑4.0 mm Hg, ‑9.4/‑7.6 mm Hg, and ‑11.8/‑9.2 mm Hg for COREG CR 20 mg, 40 mg, and 80 mg, respectively. Placebo-subtracted mean changes from baseline in mean trough (average of hours 20 to 24) SBP/DBP were ‑3.3/‑2.8 mm Hg, ‑4.9/‑5.2 mm Hg, and ‑8.4/‑7.4 mm Hg for COREG CR 20 mg, 40 mg, and 80 mg, respectively. The placebo-corrected trough to peak (3 to 7 h) ratio was approximately 0.6 for COREG CR 80 mg. In this trial, assessments of 24‑hour ABPM monitoring demonstrated statistically significant blood pressure reductions with COREG CR throughout the dosing period (Figure 5).

Immediate‑release carvedilol was studied in 2 placebo‑controlled trials that utilized twice‑daily dosing, at total daily doses of 12.5 to 50 mg. In these and other trials, the starting dose did not exceed 12.5 mg. At 50 mg per day, COREG reduced sitting trough (12‑hour) blood pressure by about 9/5.5 mm Hg; at 25 mg per day the effect was about 7.5/3.5 mm Hg. Comparisons of trough‑to‑peak blood pressure showed a trough‑to‑peak ratio for blood pressure response of about 65%. Heart rate fell by about 7.5 beats per minute at 50 mg per day. In general, as is true for other β‑blockers, responses were smaller in black than non‑black subjects. There were no age‑ or gender‑related differences in response. The dose‑related blood pressure response was accompanied by a dose‑related increase in adverse effects [see Adverse Reactions (6)].

14.4 Hypertension with Type 2 Diabetes Mellitus

In a double-blind trial (GEMINI), carvedilol, added to an ACE inhibitor or angiotensin receptor blocker, was evaluated in a population with mild‑to‑moderate hypertension and well-controlled type 2 diabetes mellitus. The mean HbA1c at baseline was 7.2%. COREG was titrated to a mean dose of 17.5 mg twice daily and maintained for 5 months. COREG had no adverse effect on glycemic control, based on HbA1c measurements (mean change from baseline of 0.02%, 95% CI: ‑0.06 to 0.10, P = NS) [see Warnings and Precautions (5.6)].

General information about COREG CR

Medicines are sometimes prescribed for conditions other than those described in patient information leaflets. Do not use COREG CR for a condition for which it was not prescribed. Do not give COREG CR to other people, even if they have the same symptoms you have. It may harm them.

This leaflet summarizes the most important information about COREG CR. If you would like more information, talk with your doctor. You can ask your doctor or pharmacist for information about COREG CR that is written for healthcare professionals. You can also find out more about COREG CR by visiting the website or calling 1-888-825-5249. This call is free.
What are the ingredients in COREG CR?

Active ingredient: carvedilol phosphate

Inactive ingredients: crospovidone, hydrogenated castor oil, hydrogenated vegetable oil, magnesium stearate, methacrylic acid copolymers, microcrystalline cellulose, and povidone

COREG CR capsules come in the following strengths: 10 mg, 20 mg, 40 mg, 80 mg.
What is high blood pressure (hypertension)? Blood pressure is the force of blood in your blood vessels when your heart beats and when your heart rests. You have high blood pressure when the force is too much. High blood pressure makes the heart work harder to pump blood through the body and causes damage to blood vessels. COREG CR can help your blood vessels relax so your blood pressure is lower. Medicines that lower blood pressure may lower your chance of having a stroke or heart attack.
