Safety Assessment of Lincomycin Following Repeated Intramuscular Administration in Goats

Abstract

Marbofloxacin (MB) is an extended spectrum, third generation fluoroquinolone, developed exclusively for the use in veterinary medicine. The safety assessment was done to evaluate the clinical impact of marbofloxacin after repeated intramuscular administration in goats. Safety of drugs is important and changes in serum biochemical and/or hematological markers could provide an early indication of cellular toxicity. The drug was administered at the dose of 2 mg/kg for 5 days by intramuscular route in six healthy, non-lactating Beetal goats, 1.5-2 yrs of age. Haematological (TLC, TEC, Hb, PCV, MCV, MCH and MCHC) and serum biochemical parameters viz. liver function test (LFT) and kidney function test (KFT) (ALT, AST, ALP, GGT, BUN, creatinine, total proteins and albumin) were determined and analyzed to establish the safety profile of marbofloxacin. The hematological and biochemical parameters were found to fluctuate within normal range during treatment period and no significant alterations (p < 0.05) were found in the mean values. The results indicated that intramuscular administration of marbofloxacin in goats at the dose of 2 mg/kg for 5 days seems to be safe.
