Antihistamine that is also anti-nausea, antipsychotic class promethazine (1st gen)
Which class of antihistamines is less effective for URI? Second generation less effective because of lower anticholinergic effects
which class of antihistamines should not be used for insomnia second generation less effective because they are less sedating

side effect of calcium, Vit D products constipation
What class of drugs cause decreased absorption of Vit D and calcium products corticosteroids
Oral forms of calcium calcium salts, usually calcium carbonate, which has highest percent calcium, cheapest
other forms of calcium salts calcium -- chloride, gluconate, glucepate, acetate, lactate, citrate

what form of activated Vitamin D is given ONLY INJECTION and is synthetic paricalcitol
What is the MOA of bisphosphonates poorest bioavailability absorbs into bone to inhibit osteoclasts
What are bisphosphonates used for prevention and treatment of osteoporosis in periomenopausal, osteoporosis in males, anyone with corticosteroid induced osteoporosis
what is a dangerous ADR with bisphosphonates esophagitis
special admin instructions for bisphosphonates first thing in AM before food, with full glass of water, stay upright with no food for at least 30 minutes
name 3 bisphosphonates alendronate, risedronate, ibandronate
Which bisphosphonates are given daily or weekly alendronate, risedronate
Which bisphosphonate is given daily or monthly ibandronate
What SERM is commonly used for osteoporosis and may also protect against estrogen-receptor-positive breat cancer raloxifine
what is the MOA of calcitonin major role to inhibit osteoclasts --> decreased bone resorption
what is the minor role of calcitonin inhibits renal reabsorption of calcium --> decreased serum calcium levels
what is an unusual ADR for some calcitonin long-term patients they can develop antibodies to this product
What is the only drug to increase bone formation teriparatide
how does teriparatide increase bone formation it is a recombinant form of PTH that increases osteoblast activity > it increases osteoclast activity. Net effect is more bone formation than reabsorption
what drug is a calcimemetic cinacalcet
What is cinacalcet's MOA increases sensitivity of calcium sensing cells in parathyroid --> negative feedback to decrease PTH secretion at lower levels of calcium than usual
what is cinacalcet given for hypercalcemia - by keeping calcium on the bone by increasing PTH receptor sensitivity

What are the general MOAs of antibiotics cell wall synthesis, membrane permeability, protein/nucleic acid synthesis, antimetabolites, viral enzyme inhibitors
the term chemotherapy, in general traditionally applies to cancer therapy, but applies equally to therapy of infectous disease
narrow spectrum vs. broad spectrum narrow targets a few microbes, broad targets many microbes
bactericidal vs. bacteriostatic cidal kills the bug, static slows its growth, giving immune system better odds to overcome
mechanisms microbial resistance resistance to drug metabolizing enzymes, drugs ability to penetrate cell, microbial receptor alteration, efflux pumps remove drug from cell, synthesis of antagonistic substances
slogan for antimicrobial resistance cure the patient today; protect the community tomorrow . . .and . . .don't medicate instead of educate
selection of antibiotic - triad concept bug-drug-patient
selection of antibiotic - factors identify likely organism, its susceptibility, host factors, drug factors
special circumstances where broad spectrum may be advisable fever unknown origin, surgical drainage/prophylactic tx, immunosuppressed host, difficult locale of pathogen (CSF, endocardum, osteomyelitis)
prophylactic antibiotics administered when first dose before incision of clean and clean/microbial contaminated surgery. agent must cover spectrum of usual etiological agents.
who long do we admin prophylactic antibiotics intra-op doses only if duration of procedure > serum level of agent used. RARELY are post-op doses necessary, may be counterproductive
classes of cancer drug therapies cytotoxic agents, hormones, biologic response modifiers
chemotherapy drugs more toxic to tissue with more toxic to tissues with high growth factors-> act more on actively growing cells
Types of fast-growing cells targeted by chemorx tumor cells, bone marrow, GI tract, skin/hair follicles, sperm
types of chemorx strategies intermittent chemo, combination chemo, optimizing dosage schedules, regional drug delivery
intermittent chemo objective results in regrowth of normal cells faster than regrowth of tumor cells

chemo side effects - GI stromatitis (ulcers), n/v some d
chemo side effects - hair alopecia
chemo side effects - hyperuricemia cell death increases byproducts resulting in increased uric acid
chemo side effects - extravasation admin needle exits vessel--> toxic chemo into tissues
chemo side effects- reproductive fetotoxic (inhibits embryogenesis), some irreversible sterility in males
