Medication Summary
The goals of pharmacotherapy are to prevent complications and to reduce morbidity.
Antimicrobials
Class Summary
Therapy must cover all likely pathogens in the context of the clinical setting.
Metronidazole (Flagyl)
A study comparing oral metronidazole to intramuscular penicillin showed better survival, shorter hospitalization, and less progression of disease in the metronidazole group (dosed at 0.5 g q6h or 1 g q12h IV for 7-10 d).
Penicillin G (Pfizerpen)
Interferes with synthesis of cell wall mucopeptide during active multiplication, resulting in bactericidal activity against susceptible microorganisms.
Doxycycline (Vibramycin)
Inhibits protein synthesis and thus bacterial growth by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria.
Benzodiazepines
Class Summary
These agents may act in the central nervous system to induce muscle relaxation.
Diazepam (Valium, Diastat, Diazepam Intensol)
Modulates postsynaptic effects of GABA-A transmission, resulting in an increase in presynaptic inhibition. Appears to act on part of the limbic system, the thalamus, and hypothalamus, to induce a calming effect. Also has been found to be an effective adjunct for the relief of skeletal muscle spasm caused by upper motor neuron disorders.
Rapidly distributes to other body fat stores. Twenty minutes after initial IV infusion, serum concentration drops to 20% of Cmax.
Individualize dosage and increase cautiously to avoid adverse effects.
