Adverse effects:N,V, abdominal cramping- rarely serious enough to discont med.
Contraindicated:Hypersensitivity to drugs in macrolide class. Drug therapy must be monitored carefully in pts with impaired hepatic or biliary function due to poss of Cholestatic hepatitis - a type of liver inflammation caused by obstruction of bile ducts.
Treatment overdose: No specific therapy available. Pts are treated symptomatically.
Nursing: Monitor hepatic function lab values more freq. Carefully monitor for diarrhea.

Definition
Therapeutic: Antibacterial
Pharmacologic: Bacterial protein synthesis inhibitor, aminoglycoside
Therapeutic effect: Used for the tx and prophylaxis of susceptible bacterial infections. Primarily for serious infections caused by aerobic, gram-negative bacilli.
MOA: Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. It is bacteriocidal that is causes premature termination of the growing polypeptide chain.
Route: IM, IV, topical
Adverse effects: Resistance to Gentamicin is increasing and cross-resistance among aminogylcosides has been reported.
Blackbox warning- Neurotoxicity- otoxocity, Neuromuscular blockage and resp paralysis, Nephrotoxicity.
Preg Cat: Cat D
Treatment Overdose: Can result in serious kidney damage and ototoxicity. No specific therapy is available, tx'd symptomatically.
Nursing: Monitor renal function lab values, monitor for changes in hearing/balance freq, monitor for diarrhea. |

Therapeutic: Antibacterial
Pharmacologic: Bacterial DNA replication inhibitor, fluoroquinolone
Therapeutic effect: Second generation fluoroquinolone. Prescribed for UTI, sinusitis, pneumonia, skin, bone and joint infections, infectious diarrhea, and certain eye infections.
MOA: Inhibits bacterial DNA gyrase and topoisomerase, ciprofloxacin affects bacterial replication and DNA repair.
Route: PO, IV, opthalmic and otic drops
Adverse effects: Well tolerated, serious adverse effected uncommon. N, V, diarrhea. May be taken with food to diminish GI upset.
Blackbox warning- Tendinitis and tendon rupture may occur in all ages. Risk esp in >60 yr in kidney, heart, and lung transplant recipients.
Treatment overdose: No specific tx, tx'd symptomatically.
Nursing: Monitor older adults for joint pain, tendon pain, or difficulty with gait. Increased risk of tendonitis and tendon rupture. Carefully monitor for diarrhea. Do not take products containing magnesium or calcium, iron, or aluminum within 2 hrs of taking drug. Report sudden joint or tendon pain, tendinitis, or difficulty walking/ movement. |
