Adv Pharm Quiz 1 Flashcards
Antibiotics that inhibit cell wall function
Beta-lactams: PCNs and Cephalosporins
Live-attenuated virus vaccines (4)
MMR
Varicella
Rota
Shingles
Can confer lifetime immunity in less doses but inc risk with weak immune systems
Antibiotics that inhibit PRO synthesis
Macrolides
Tetracyclines
Aminoglycosides
general AEs of NSAIDS (4)
ulcers/GI bleed
anemia
renal impairment
edema/HTN
First Pass Effect
PO drugs absorbed from gut pass through liver before going into general circulation and can be metabolized/inactivated there to varying degrees
treatment for acute gout exacerbation (3)
- short term course of Indomethacin/Naproxen
- Colchicine to inhibit inflammatory response to urate crystals
- Push fluids
Phase 2 metabolism
Conjugation-drug combines with another molecule to increase water solubility for better elimination
Fluoroquinolones and AEs
Ciprofloxacin, Levaquin, Moxifloxacin
tendon rupture <18 yrs
CNS effects-DZNS, confusion, seizures Photosensitivity
Preg Cat C
*Save for when needed*
Glucocorticoid AEs
inc bg
thickened trunk with thin extremities and face
thin skin, easy bruising
edema, HTN
poor wound healing
abd striation
mood swings, excitability—>>>psychosis
temporary antagonists are
competitive antagonists
No EtOH with this antibiotic as it causes an Antabuse-like reaction
metronidazole (Flagyl)
Do not use ASA in kids b/c
risk of Reye’s syndrome if used during a viral infection
DOC for dermatophytes (tinea infections)
Terbinafine *baseline and monitor LFTs
Why is ASA used for MI/CVA prophylaxis
dec risk MI by 50%
dec atherosclerosis, an inflammatory process
use 50-59 yrs old if 10 yr risk is >10%
DOC for tinea capitus, scabies
griseofulvin PO only, with hi fat food
*baseline and monitor LFTs
AEs of NSAIDS in pregnancy
impaired contractions (late pregnancy)
miscarriage (early pregnancy)
amount of drug that reaches systemic circulation
bioavailability
acetominophen mechanism
inhibits Cox 2 in CNS, not in periphery–good for pain and fever but not antiinflammatory
Acetominophen
safer than NSAIDS for pain/fever without inflammation IF no liver or kidney disease–Ex. OA
Celebrex carries this risk, even more than non selective NSAIDS Use Celebrex in these patients
MI, CVA, HF (inhibition of cardioprotection from Cox2 with no inhibition of plt agg in COX-1)
Use in young pt, no CV disease, with an inflammatory process like arthritis
Leukotriene modifier indications
allergic rhinitis
PO adjunct for asthma (when already using ICS)
Singulair good for EI asthma
The two ways the liver metabolizes drug
- Partial or complete inactivation
- Activation of prodrug
Abx with a beta lactamase inhibitor
Augmentin - Amox and clavulinic acid
Zosyn
Unasyn
Fluoroquinolones indication
Effective for multi-purpose but save for when needed due to AEs
AEs of 1st gen H1RB antihistamines (2)
sedation and can prolong QTc
need PCN coverage but pt has true PCN allergy
Macrolides (erythromycin, azithromycin)
Functions of Cox-1 Prostaglandins (6)
“housekeeping”
protects gastric mucosa
inhibits gastric acid secretion
stimulates plt aggregation
renal vasodilation (protective)
stimulation of uterine contractions
cardioprotective
Toxoid vaccines-use pathogen toxin
Diptheria
tetanus
boosters needed
Daily maintenance -gout
allopurinol–prevents formation and deposition of urate crystals
Bactrim indications
Go to for MRSA
Go to for UTI (Gm- enterococcus coverage)
Phase 1 metabolism
Oxidation, reduction, hydrolysis
CYP450 oxidation enzyme family
treatment of atypical bacteria (Mycoplasma and Chlymidia)
Macrolides or doxycycline
elderly are increasingly sensitive to (2) and this puts them at risk for
sedation
hypotension
falls/fractures
Macrolide indications
atypicals (mycoplasma walking PNA, chlymidia)
Go to drug to replace PCN in true PCN allergy
If a drug needs a much higher PO dose than IV dose it is most likely due to
first pass effect
temporary interaction b/t drug and receptor
reversible agonist/antagonist
Flagyl indications
anaerobic infections
protozoal infections
C. diff
SLE med to start first at diagnosis and use daily to dec flares, slow progression; does not impair immune function
hydroxychloroquine (Plaquenil) anti-malarial
Tetracyclines and AEs of them
tetracycline
doxycycline
minocycline
Not for kids and preggos d/t tooth discoloration and interference with tooth development
four molecules that highly bind plasma proteins
warfarin
calcium
thyroxine
steroids
permanent antagonists are
non-competitive inhibitors
Gm- organisms release endotoxins/LPS from here when they die—>sepsis
outer PM (GM+ have no outer PM)
