Answer

Antibiotics

Antibiotics may have immunomodulatory activity. Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting.

Tetracycline (Sumycin)

Tetracycline treats gram-positive and gram-negative organisms, as well as mycoplasmal, chlamydial, and rickettsial infections. It inhibits bacterial protein synthesis by binding with 30S and possibly 50S ribosomal subunit(s).

Erythromycin (E.E.S., E-Mycin, Ery-Tab)

Erythromycin inhibits bacterial growth, possibly by blocking dissociation of peptidyl tRNA from ribosomes, causing RNA-dependent protein synthesis to arrest. It is used for staphylococcal and streptococcal infections.

In children, age, weight, and severity of infection determine proper dosage. When twice-daily dosing is desired, half the total daily dose may be administered every 12 hours. For more severe infections, the dose is doubled.
