Mediterranean Spotted Fever Medication
- Author: Jason F Okulicz, MD; Chief Editor: Michael Stuart Bronze, MD more...
Medication Summary
The goals of pharmacotherapy are to reduce morbidity, to prevent complications, and to eradicate the infection. Patients with Mediterranean spotted fever typically improve within 24 hours after initiation of therapy, and a delay in response should cast doubt on the diagnosis.
Antibiotics
Class Summary
Empiric antimicrobial therapy must be comprehensive and cover all likely pathogens in the context of this clinical setting.
In an analysis of risk factors for malignant Mediterranean spotted fever, researchers noted that fluoroquinolone may have a deleterious effect.[6]
Doxycycline (Vibramycin)
Tetracycline with broad spectrum of activity. Inhibits protein synthesis and thus bacterial growth by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria.
Ciprofloxacin (Cipro)
Fluoroquinolone with activity against most gram-negative organisms but no activity against Bacteroides fragilis. Inhibits bacterial DNA synthesis and consequently growth.
Levofloxacin (Levaquin)
Second-generation quinolone. Acts by interfering with DNA gyrase in bacterial cells. Bactericidal. Highly active against gram-negative and gram-positive organisms, including Pseudomonas aeruginosa.
Chloramphenicol (Chloromycetin)
Binds to 50S bacterial-ribosomal subunits and inhibits bacterial growth by inhibiting protein synthesis. Effective against gram-negative and gram-positive bacteria.
Azithromycin (Zithromax)
Acts by binding to 50S ribosomal subunit of susceptible microorganisms and blocks dissociation of peptidyl tRNA from ribosomes, causing RNA-dependent protein synthesis to arrest.
Clarithromycin (Biaxin)
Semisynthetic macrolide antibiotic that reversibly binds to P site of 50S ribosomal subunit of susceptible organisms and may inhibit RNA-dependent protein synthesis by stimulating dissociation of peptidyl t-RNA from ribosomes, causing bacterial growth inhibition.
