BONE.SMOOTHM.ANTIMICROB Flashcards
Available bisphosphonates
Alendronate, etidronate, risedronate, pamidronate, tiludronate, and zoledronic acid
MOA of Bisphosphonates
Inhibits osteoclast bone resorption
Uses of bisphosphonates
Osteoporosis, Paget’s disease, and osteolytic bone lesions, and hypercalcemia from malignancy
Major SE of bisphosphonates
Chemical esophagitis
Bisphosphonates that cannot be used on continuous basis because it caused osteomalacia

Used for prevention of postmenopausal osteoporosis in women
Calcium reguators Bisphosphonates: alendronate, risedronate, ibandronate, Estrogen (HRT-Hormone replacement therapy)
Increase bone density, also being tested for breast CA tx.
Raloxifene (SERM-selective estrogen receptor modulator)
Used intranasally and decreases bone resorption
Calcitonin (salmon prep)

Distribution of histamine receptors H1, H2, and H3
Smooth muscle and mast cells; stomach, heart, and mast cells; nerve endings, CNS respectively
1st generation antihistamine that is highly sedating
Diphendydramine
1st generation antihistamine that is least sedating
Chlorpheniramine
2nd generation antihistamines
Fexofenadine, loratadine, and cetirizine

Clinical use for H2 blockers
Acid reflux disease, duodenal ulcer and peptic ulcer disease
Receptors for serotonin (5HT-1) are located
Mostly in the brain, and they mediate synaptic inhibition via increased K+ conductance
