Cinacalcet (Sensipar) has been shown to decrease calcium levels in patients with primary hyperparathyroidism (PHPT); however, few other endpoints have been studied and long-term effects are not known.
At the discretion of a referring doctor, 70 patients began Cinacalcet as an alternative to surgery for PHPT. Patients were followed as long as the drug was tolerated at which time all underwent parathyroidectomy.
Before treatment, serum calcium levels averaged 11.7 ± 0.5 (range, 11.0-15.1) and PTH averaged 156 ± 42 (range, 88-815); 93% had two or more classic parathyroid symptoms (average, 5.3; range, 0-9). Cinacalcet was discontinued in 19 patients (26%) within 4 months because of nausea/vomiting. The remainder (n = 51) were treated from 8 to 28 months. Calcium levels decreased in all patients but remained variable. PTH levels decreased in 80% of patients but always remained elevated. Only 3 (6%) had symptom relief (p = 0.8), whereas 11 (21.6%) felt worse (p < 0.05). Twenty-three patients took Cinacalcet for >1.5 years, 14 of which showed significant (>1 SD) decreases in bone density (p < 0.05), and none had increases in bone density. All had curative outpatient parathyroid surgery followed by partial or complete resolution of symptoms within 3 months in 88% (p < 0.001).
Cinacalcet reduces serum calcium but is not tolerated by many patients. Cinacalcet does not provide symptom relief of PHPT and more commonly increases subjective symptoms. Prolonged use is associated with continued bone loss in some patients, possibly due to persistent elevated PTH levels. With very few exceptions, pHPT can be cured via a quick outpatient operation, which remains the treatment of choice.

A 1974 Federal act which preempts states' rights with regard to workers' pension benefits and employee benefits. It does not affect the benefits and rights of employees whose employer is self-insured. (From Slee & Slee, Health Care Reform Terms, 1993)
The remuneration paid or benefits granted to an employee.
Determination of the degree of a physical, mental, or emotional handicap. The diagnosis is applied to legal qualification for benefits and income under disability insurance and to eligibility for Social Security and workmen's compensation benefits.
Payments or services provided under stated circumstances under the terms of an insurance policy. In prepayment programs, benefits are the services the programs will provide at defined locations and to the extent needed.
A selective beta-1-adrenergic partial agonist. Because it is a partial agonist (DRUG PARTIAL AGONISM) it acts like an agonist when sympathetic activity is low and as an antagonist when sympathetic activity is high. It reduces MYOCARDIAL ISCHEMIA and improves ventricular function in patients with mild to moderate heart failure. In patients with severe heart failure it has been shown to produce benefits in systolic and diastolic function.
