Prolia Osteoporosis drug treatment byAmgen was approved by the FDA in June of 2010. The drug is a RANK Ligand inhibitor is taken 60 mg subcutaneous injection administered by a health care professional every six months. Clinically it is known as Denosumab.
Since this drug is administered by injection twice a year it eliminates of the main problems of some Osteoporosis medications:
But you should know that this is not the first Osteoporosis drug that is not in pill form:
So as you can see, if you prefer injection as your Osteoporosis treatment, you have several options.
What is different about this drug is that it is the first biologic drug for Osteoporosis. (NOTE: Patients taking other biologic drugs, eg. for Rheumatoid arthritis, may have interactions.)
Also this drug will be sold directly to doctors. So it can be delivered by a physician 'almost like a flu shot' in the office.
Clinical studies of the drug showed that women taking the drug had increased bone density, stronger bones, and a reduced risk for fractures after three years of treatments.(If you want to review some of the early clinical studies, I put a page on the site about these as soon as Amagen announced that it was under review by the FDA.

Possible side effects of Prolia Osteoporosis drug includes back and extremity pain, high cholesterol, bladder infection, low blood calcium and skin reactions. Since the cells targeted by Prolia play a role in immunity, the drug "has the potential to affect multiple layers of the immune system," according to the FDA. Also because it blocks the work of osteoclasts some have warned that users could suffer from Osteonecrosis of the jaw...just as with Fosamax and the other bisphosphonates BUT this is not known withany degree of certainty.
A press release from Amgen states: This drug "is contraindicated in patients with hypocalcemia. Pre-existing hypocalcemia must be corrected prior to initiating Prolia. Hypocalcemia may worsen, especially in patients with severe renal impairment. All patients should be adequately supplemented with calcium and vitamin D.
In the pivotal study, serious infections leading to hospitalizations were reported more frequently in the Prolia-treated patient group. Serious skin infections, as well as infections of the abdomen, urinary tract and ear, were more frequent in patients treated. . . Patients should be advised to seek prompt medical attention if they develop signs or symptoms of severe infection, including cellulitis. Endocarditis was reported more frequently in the . . treated patient group. Epidermal and dermal adverse events such as dermatitis, rashes, and eczema have been reported. Discontinuation of Prolia should be considered if severe symptoms develop. . . .
(It) resulted in significant suppression of bone remodeling. The significance of these findings is unknown. The long-term consequences of the degree of suppression of bone remodeling observed with Prolia may contribute to adverse outcomes such as osteonecrosis of the jaw (ONJ), atypical fractures, and delayed fracture healing. ONJ has been reported in patients . . . Patients should be monitored for these adverse outcomes. The most common adverse reactions (> 5 percent and more common than placebo) were back pain, pain in extremity, musculoskeletal pain, hypercholesterolemia, and cystitis. Pancreatitis has also been reported ..." The full press release can be found at Prolia press release from Amgen
In February of 2014 the journal Acta Othepedica published a paper that reviewed side effects of Prolia Osteoporosis drug. It stated : "Based on the mechanism of action, one could speculate that denosumab may
be associated with a similar risk of atypical fracture as most
bisphosphonates." Since densosumab and Prolia are the same medication, this study Will be of interest to anyone thinking of using this drug. You can read the full study at Densosumab and Atypical Fractures
