What are the other drugs used for osteoporosis besides bisphosphonates and SERMs?
Calcitonin, Cinacalcet, Denosumab, Teriparatide
What is the source of calcitonin?
Secreted by the thyroid gland
What is the mechanism of action of calcitonin?
Decreases bone resorption and increases urinary calcium excretion; lowers serum calcium
What conditions is calcitonin used to treat?
Osteoporosis, Paget disease, hypercalcemia
What is calcitonin’s relationship to vitamin D and PTH?
It is considered their “enemy”—it opposes their effects
What is the role of Cinacalcet (Sensipar)?
Mimics calcium to suppress PTH secretion, lowering calcium levels
What conditions is Cinacalcet used for?
Hypercalcemia, hyperparathyroidism
What are adverse effects of Cinacalcet?
Nausea, vomiting, diarrhea, hypocalcemia
What is Denosumab (Prolia, Xgeva) used for?
Osteoporosis in men and postmenopausal women, bone loss from cancer therapy, bone metastases
What are the adverse effects of Denosumab?
Hypocalcemia, serious infections, dermatologic reactions, osteonecrosis of the jaw
What type of drug is Teriparatide (Forteo)?
A recombinant form of human parathyroid hormone (PTH)
What is unique about Teriparatide’s action?
It’s the only drug that increases bone formation
Who is Teriparatide indicated for?
Men, postmenopausal women, and those with glucocorticoid-induced osteoporosis
What are adverse effects of Teriparatide?
Nausea, headache, back pain, leg cramps
What is osteoarthritis (OA)?
A progressive degenerative joint disease caused by breakdown of articular cartilage
What are some joint changes in OA?
Thinning cartilage, bone spurs/cysts, inflamed synovial membrane
What are symptoms of OA?
Pain, stiffness, paresthesias, decreased ROM
What are nonpharmacologic treatments for OA?
Walking, nonimpact aerobics, passive ROM exercises
What are pharmacologic options for OA?
Acetaminophen, NSAIDs, intra-articular corticosteroids, hyaluronate sodium, topical meds like capsaicin, Bengay
What is rheumatoid arthritis (RA)?
A chronic, progressive autoimmune disease causing joint inflammation and deformity
What happens pathophysiologically in RA?
Rheumatoid factors and leukocytes attack synovial membranes
How does RA differ from OA?
RA is autoimmune and systemic; OA is mechanical and localized
Who is more likely to get RA?
Women (3–5x more likely than men)
What are nonpharmacologic therapies for RA?
ROM and strengthening exercises, psychological counseling
