Amneal Pharmaceuticals of New York LLC

1 INDICATIONS AND USAGE

1.1 Primary Hyperlipidemia

Colesevelam hydrochloride tablets are indicated as an adjunct to diet and exercise to reduce elevated low-density lipoprotein cholesterol (LDL-C) in adults with primary hyperlipidemia.

Colesevelam hydrochloride tablets are indicated to reduce LDL-C levels in boys and postmenarchal girls, 10 to 17 years of age, with heterozygous familial hypercholesterolemia (HeFH) who are unable to reach LDL-C target levels despite an adequate trial of dietary therapy and lifestyle modification.

1.3 Limitations of Use

  • Colesevelam hydrochloride tablets should not be used for the treatment of type 1 diabetes or for the treatment of diabetic ketoacidosis.
  • The effect of colesevelam hydrochloride tablets on cardiovascular morbidity and mortality has not been determined.
  • Colesevelam hydrochloride tablets have not been studied in type 2 diabetes in combination with a dipeptidyl peptidase 4 inhibitor.
  • Colesevelam hydrochloride tablets have not been studied in Fredrickson Type I, III, IV, and V dyslipidemias.
  • Colesevelam hydrochloride tablets have not been studied in children younger than 10 years of age or in premenarchal girls.

2 DOSAGE AND ADMINISTRATION

2.1 Testing Prior to Initiation of Colesevelam Hydrochloride Tablets

Obtain lipid parameters, including triglyceride (TG) levels, before starting colesevelam hydrochloride tablets. Colesevelam hydrochloride tablets are contraindicated in patients with TG levels > 500 mg/dL [see Contraindications (4) and Warnings and Precautions (5.1)].

2.2 Recommended Dosage in Primary Hyperlipidemia

The recommended dosage of colesevelam hydrochloride tablets for adults and children 10 to 17 years old with primary hyperlipidemia is 3.75 grams daily. Colesevelam hydrochloride tablets should be taken as follows:

Tablets

Take 6 tablets once daily or 3 tablets twice daily. Due to tablet size, colesevelam hydrochloride for oral suspension is recommended for use in the pediatric population.

2.3 Important Dosing Information for Primary Hyperlipidemia

Colesevelam hydrochloride can be dosed at the same time as a statin, or colesevelam hydrochloride and the statin can be dosed apart. Monitor lipid levels within 4 to 6 weeks after initiation of colesevelam hydrochloride.

2.4 Administration Instructions

Tablets

Take colesevelam hydrochloride tablets with a meal and liquid. For patients with difficulty swallowing tablets, use colesevelam hydrochloride for oral suspension [see Warnings and Precautions (5.2)].

3 DOSAGE FORMS AND STRENGTHS

  • 625 mg tablets are off-white to pale yellow film-coated oval tablets, debossed with “L61” on one side and plain on the other side.

4 CONTRAINDICATIONS

Colesevelam hydrochloride is contraindicated in patients with:

5 WARNINGS AND PRECAUTIONS

5.1 Hypertriglyceridemia and Pancreatitis

Colesevelam hydrochloride, like other bile acid sequestrants, can increase serum TG concentrations. Hypertriglyceridemia can cause acute pancreatitis.

Colesevelam hydrochloride had effects on serum TG (median increase 5% compared to placebo) in trials of patients with primary hyperlipidemia.

Obtain lipid parameters, including TG levels, before starting colesevelam hydrochloride and periodically thereafter. Colesevelam hydrochloride is contraindicated in patients with TG levels > 500 mg/dL or patients with a history of hypertriglyceridemia-induced pancreatitis [see Contraindications (4)]. Patients with TG levels greater than 300 mg/dL could have greater increases in serum TG levels with colesevelam hydrochloride and may require additional TG monitoring. Instruct patients to discontinue colesevelam hydrochloride and seek prompt medical attention if the symptoms of acute pancreatitis occur (e.g., severe abdominal pain with or without nausea and vomiting). Discontinue colesevelam hydrochloride if TG levels exceed 500 mg/dL [see Adverse Reactions (6.1)].

5.2 Gastrointestinal Obstruction

Postmarketing cases of bowel obstruction have occurred with colesevelam hydrochloride [see Adverse Reactions (6.2)]. Because of its constipating effects, colesevelam hydrochloride is not recommended in patients with gastroparesis, other gastrointestinal motility disorders, and in those who have had major gastrointestinal tract surgery and who may be at risk for bowel obstruction. Colesevelam hydrochloride is contraindicated in patients with a history of bowel obstruction [see Contraindications (4)]. Instruct patients to promptly discontinue colesevelam hydrochloride and seek medical attention if severe abdominal pain or severe constipation occurs.

Because of the tablet size, colesevelam hydrochloride tablets can cause dysphagia or esophageal obstruction. For patients with difficulty swallowing tablets, use colesevelam hydrochloride for oral suspension.

5.3 Vitamin K or Fat-Soluble Vitamin Deficiencies

Colesevelam hydrochloride may decrease the absorption of fat-soluble vitamins A, D, E, and K. Patients with a susceptibility to deficiencies of vitamin K (e.g., patients on warfarin, patients with malabsorption syndromes) or other fat-soluble vitamins may be at increased risk when taking colesevelam hydrochloride.

Patients on oral vitamin supplementation should take their vitamins at least 4 hours prior to colesevelam hydrochloride [see Drug Interactions (7.1)].

5.4 Drug Interactions

Colesevelam hydrochloride reduces gastrointestinal absorption of some drugs. Administer drugs with a known interaction at least 4 hours prior to colesevelam hydrochloride [see Drug Interactions (7)].

Due to the potential for decreased absorption of other drugs that have not been tested for interaction, especially those with a narrow therapeutic index, consider administering at least 4 hours prior to colesevelam hydrochloride [see Clinical Pharmacology (12.3)].

5.6 Macrovascular Outcomes

There have been no clinical studies establishing conclusive evidence of macrovascular disease risk reduction with colesevelam hydrochloride.

6 ADVERSE REACTIONS

The following important adverse reactions are described below and elsewhere in the labeling:

6.1 Clinical Studies Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice.

Primary Hyperlipidemia

In 7 double-blind, placebo-controlled clinical trials, 807 patients with primary hyperlipidemia (age range 18 to 86 years, 50% women, 90% Caucasians, 7% Blacks, 2% Hispanics, 1% Asians) and elevated LDL-C were treated with colesevelam hydrochloride 1.5 g/day to 4.5 g/day from 4 to 24 weeks (total exposure 199 patient-years).

Pediatric Patients 10 to 17 Years of Age

In an 8-week double-blind, placebo-controlled study, boys and post-menarchal girls, 10 to 17 years of age, with HeFH (n=194), were treated with colesevelam hydrochloride tablets (1.9 g to 3.8 g, daily) or placebo tablets.
