Medication Summary
The goal of therapy is the eradication of the organism. Considerations for medical treatment include pregnancy and HIV status and compliance. In addition, medication to cover multiple STDs are usually instituted. Symptomatic improvement after medical treatment is usually seen in 3 days, and objective evidence of ulcer healing in a week. Treatment failures may occur if the patient is not compliant with the medication or if the wrong diagnosis was made, as well as in HIV patients who may need a prolonged course of treatment.
Antibiotics
Class Summary
Therapy must be comprehensive and cover all likely pathogens in the context of the clinical setting.
Azithromycin (Zithromax)
Treats mild-to-moderate microbial infections.
Ceftriaxone (Rocephin)
Third-generation cephalosporin with broad-spectrum gram-negative activity. Lower efficacy against gram-positive organisms. Higher efficacy against resistant organisms. Arrests bacterial growth by binding to 1 or more penicillin-binding proteins.
Erythromycin (E.E.S., E-Mycin, Eryc, Ery-Tab, Erythrocin)
Inhibits bacterial growth, possibly by blocking dissociation of peptidyl tRNA from ribosomes, causing RNA-dependent protein synthesis to arrest. For treatment of staphylococcal and streptococcal infections.
Ciprofloxacin (Cipro)
Fluoroquinolone with activity against pseudomonads, streptococci, MRSA, Staphylococcus epidermidis, and most gram-negative organisms, but no activity against anaerobes. Inhibits bacterial DNA synthesis and, consequently, growth.
