Cinacalcet Hydrochloride

Cinacalcet hydrochloride is a calcium-sensing receptor agonist indicated for: Secondary Hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on dialysis. ( 1.1 ) Limitations of Use: Cinacalcet hydrochloride tablets are not indicated for use in patients with CKD who are not on dialysis. Hypercalcemia in adult patients with Parathyroid Carcinoma (PC).

1.1Secondary Hyperparathyroidism

Cinacalcet hydrochloride tablets are indicated for the treatment of secondary hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on dialysis [see Clinical Studies ( 14.1 )]. Limitations of Use: Cinacalcet hydrochloride tablets are not indicated for use in patients with CKD who are not on dialysis because of an increased risk of hypocalcemia [see Warnings and Precautions ( 5.1 )].

1.2Parathyroid Carcinoma

Cinacalcet tablets are indicated for the treatment of hypercalcemia in adult patients with Parathyroid Carcinoma [see Clinical Studies ( 14.2 )] .

1.3Primary Hyperparathyroidism

Cinacalcet hydrochloride tablets are indicated for the treatment of severe hypercalcemia in adult patients with primary HPT who are unable to undergo parathyroidectomy [see Clinical Studies ( 14.3 )] .

Cinacalcet hydrochloride tablets treatment initiation is contraindicated if serum calcium is less than the lower limit of the normal range [see Warnings and Precautions ( 5.1 )]. Cinacalcet tablets treatment initiation is contraindicated if serum calcium is less than the lower limit of the normal range. ( 4 , 5.1 )

Hypocalcemia: Life threatening events and fatal outcomes were reported. Hypocalcemia can prolong QT interval, lower the threshold for seizures, and cause hypotension, worsening heart failure, and/or arrhythmia. Monitor serum calcium carefully for the occurrence of hypocalcemia during treatment. ( 2.4 , 5.1 ) Upper Gastrointestinal (GI) Bleeding: Patients with risk factors for upper GI bleeding may be at increased risk.
