Pharmacokinetics of Immediate and Sustained Release Cephalexin Administered by Different Routes to Llamas (Lama glama)

Table 4

Time above MIC₉₀ ( > MIC) calculated for long-acting cephalexin following an intramuscular (IM) and subcutaneous (SC) 8 mg/kg injection to 6 llamas. Results are expressed in hours (h) and dosing interval (DI) percentage.
