Question | Answer |
factors that affect the absorption of drugs in the elderly | decreased GI motility, decreased GI blood flow, increased gastric pH |
if GI motility is decreased but GI blood flow is decreased how is absorption affected in the elderly | absorption time is increased therefore drug absorption is quantitatively unaffected |

meds indicated in atrial fibrillation | warfarin |
what is the Beers criteria used to address | inappropriate medication use in the older adult |
characteristics of osteoporosis | low bone mass, deterioration of bone tissue and disruption of bone architecture, comprimised bone strength, and an increase in the risk of fracture |
peak bone mass by age __ | 25-30 |
removal of older bone, replaced with new bone | bone remodeling |
function of osteoclasts | breakdown old bone (clasts-crunch) |

FDA approved bisphosphonates | alendronate (fosamax), ibandronate (boniva), risedronate (actonel), zoledronic acid (reclast) |
bisphosphonate MOA | decrease bone resorption by binding to the bone matrix and inhibiting osteoclast activity. remains in bone for a long period of time |

parathyroid hormone MOA when given once daily | preferential stimulation of osteoblastic activity over osteoclastic activity |
parathyroid hormone AE | Cardiovascular (hypotension, syncope), Derm (rash, sweating), Endocrine (hyperuricermia), GI (constipation, diarrhea, indigestion, N/V), Musculoskeletal (arthralgia/spasm), Neurologic (asthenia, dizziness), resp (cough, pharyngitis, rhinitis) |
