TY - JOUR T1 - GUidelines for treatment of anthrax AU - Tice AD Y1 - 2002/10/16 N1 - 10.1001/jama.288.15.1845 JO - JAMA SP - 1848 EP - 1849 VL - 288 IS - 15 N2 - I was concerned, however, that the authors did not recommend loading doses of antibiotics. Without a loading dose, serum levels do not reach a steady state until after several doses of the drug have been administered. For compartments such as infected lymph nodes and the mediastinum, effective concentrations would be even more difficult to achieve. This may be a particular problem for doxycycline, which has a half-life of 18 hours.2 A loading dose of twice the standard intermittent dose should carry no more likelihood of toxicity than a regular dose and may be appropriate for ciprofloxacin as well.
