Indications for Gentamicin
treatment of serious infection caused by susceptible bacteria
Actions of Gentamicin
Inhibits protein synthesis in susceptible GRAM-NEGATIVE AEROBIC BACILLI bacteria, disrupting functional integrity of the cell membrane and causing cell death.
Pharm of gentamicin
IM, IV route
Rapid Onset
30-90min peak
half-life of gentamicin
2-3 hr. metabolized in the liver and excreted in the urine.
Adverse effects of gentamicin
sinusitis, dizziness, rash, fever risk of nephrotoxicity, ototoxicity, GI irritation, bone marrow suppression thus need to look at BUN & creatines.(contraindicated in renal/ hepatic disease)
Indications for ertapenem
treatment of community-acquired pneumonia, complicated intra-abdominal infections, skin and skin-structure infections and acute pelvic infections caused by susceptible bacteria.
Actions of ertapenem
Inhibits protein synthesis in susceptible strains of gram-negative bacteria, disrupting functional integrity of the cell membrane and causing cell death. [bacteiostatic protein synthesis]
In general carbapenems are used to treat gram + & gram - making them broad spectrum antibiotics.
parmo etrapenem
IV, IM route
Rapid onset
30-120min peak
half-life etrapenem
4 hr, excreted unchanged in the urine
adverse effects etrapenem
HA, dizziness, N/V, pseudomembranous colitis, rash, pain at the joint site.
Indications for cefaclor
Treatment of respiratory, dermatological, UTI’s and middle ear infections caused by susceptible strains of bacteria.
Action of cefaclor
Inhibits the synthesis of bacterial cell walls, causing cell death in susceptible bacteria.
parmo of cefaclor
oral route
30-60 min peak
8-10 h duration
