If someone has been treated with antibiotic floxacin (fluoroquinolone)
for CAP in last 90 days, what class of
medication would be best
chlamydial pneumonia in infant erythromycin 12.5mg/kg PO QID x 14 days
active against wide variety of microbes
broad spectrum
-gram + cocci and gram - bacilli
active against only a few species of specific microorganisms
narrow spectrum
- gram + cocci, gram - bacilli, gram - aerobes, mycobacterium TB
ciprofloxacin, TMP/SMZ, amoxicillin
-severe infections that may need tx prior to knowing test results
empiric antibiotics
-tx is based on eval and knowledge of microbes that are most likely causing the
infection
c. diff associated diarrhea STOP prior abx and start vancomycin or fidaxomicin
drug class known for all drugs in class to bacteriostatic inhibitors
promote c. diff
what class of medications has a cross cephalosproins
sensitivity to PCN
there is no second or third trimester fetal risk
Is PCN safe in pregnancy
no controlled studies
do not take if allergic to pcn. Interacts with alcohol, clotting factors, vitamin K.
cephalosporins
Increased risk of c diff so check stools
cephalosporin safe in pregnancy? yes
discoloration of teeth, avoid <8 yrs. avoid prolonged sun exposure. risk for c diff,
renal/hepatic toxicity
tetracycline
do not take with calcium, milk, iron, mag containing laxative, and most antacids. N/V/D.
Rxns can decrease if taken with meals
tetracycline safe in pregnancy fetal harm- suppression of growth of long bones
macrolides can cause QT prolongation risk for torsades de pointes. n/v/d
aminoglycosides serious toxicity to inner ear (HA, nausea, dizzy, tinnitus, vertigo), toxic to kidneys
-drink 8-10 glasses of water to reduce risk of crystalluria
-photosensitive use sunblock
sulfanomides -CBC, CD4 if HIV
-renal adjustment 50% if CR clearance 15-30
-birth defects 1st trimester, near term is kernicterus
gentamicin renal toxic, need adjustments
oral griseofulvin 8-10 weeks
tinea capitis (ringworm)
-oral terbinafine taken 2-4 weeks may be more effective
aspergillosis treatment voriconazole
which anthelmintic drugs carry risk ivermectin and moxidectin
for hypotension with patients on
antihypertensives?
which anthelmintic drugs cause bone albendazole and mebendazole
marrow suppression and liver
impairment?
