Cinacalcet binds to the parathyroid calcium-binding receptor, leading to decreased release of PTH.

For mild to moderate cancer-associated pain short-acting opioid is indicated when non-opioid drugs fail to control the pain. Once pain control is achieved long-acting opioid dosage can be calculated.

What is the difference between dihydropyridine and non-dihydropyridine calcium channel blockers? |
|
Definition
Dihydropyridine (amlodipine, nifedipine, felodipine) - used to reduced systemic vascular resistance and arterial pressure. Vasodilation & hypotension can → reflex tachycardia. Although most ccb's are not used to tx angina b/c of tachy reflex, amlodipine, nicardipine, and nifedipine can be used to treat chronic stable angina as well as vasospactic angina.
Non-dihydropyridine (verapamil) - relatively selective for myocardium and often used to treat angina.
