Benzylpenicillin shows a marked bactericidal action against most commonly occurring Gram-positive cocci,bacilli and anaerobes, and also against some Gram-negative germs (e.g. Actinobacillus, Haemophilus, Leptospiren, some Pasteurella strains, anaerobes such as Fusobacterium and Bacteroides). By use of the procaine salt of penicillin G, a high initial penicillin blood level is achieved. The more slowly absorbed benzathine salt provides a prolonged therapeutical blood level for 72 hours.
DHS is an aminoglycoside antibiotic predominantly active against Gram-negative cocci and bacilli, and also against some Gram-positive bacteria (e.g. Staph. aureus, Mycobacterium).
The combination of DHS and penicillin provides a bactericidal synergistic action with a broad spectrum.
Prevention and treatment of infections caused by penicillin G and/or DHS susceptible microorganisms, such as respiratory tract infections (shipping fever, bronchopneumonias, upper respiratory tract infections), urogenital tract infections (e.g. pyelonephritis by Corynebacterium renale, endometritis), infections of skin and wounds, streptococci infections in horses (strangles, Str. zooepidemicus infections in foals), panaritium, necrobacillosis in calves, anaerobe infections (clostridial infections, tetanus, anthrax), polyarthritis (navel ill), mastitis, septicaemia, bacterial infections secondary to viral ones.
The drug also can be used in postoperative prevention of infections.
