Amclomast DC

600 mg Cloxacillin + 300 mg Ampicillin Intramammary suspension for cows

Amclomast DC is indicated for the prevention (one-step drying off) and treatment of mastitis caused by bacteria sensitive to cloxacillin and ampicillin in cows at drying off.
Amclomast DC is a combination of semi-synthetic penicillins (ampicillin and cloxacillin), which exhibits extended bactericidal activity against most mastitis causing pathogens including penicillin-resistant strains. It provides an extended spectrum of efficacy against both Gram-negative and Gram-positive bacteria (Streptococcus agalactiae, Streptococcus dysgalactiae, Staphylococcus spp., Corynebacterium pyogenes, Escherichia coli, Pseudomonas spp., etc.). Cloxacillin is also active against beta-lactamase–producing strains.
