Shotapen® LA is a ready-to-use injectable preparation that combines the benzylpenicillins procaine and benzathine with dihydrostreptomycin, which gives the product not only a broad spectrum, but also a prolonged period of action.

Procaine and benzathine benzylpenicillins are potent antibiotics from the Beta-lactam family that act by inhibiting the synthesis of the bacterial cell wall through interference with the transpeptidase enzyme.

Penicillin is a highly active against Gram-positive microorganisms - both aerobic and anaerobic such as Staphylococcus spp., Streptococcus spp., Corynebacterium diphtheriae, and others. 

Dihydrostreptomycin is an aminoglycoside antibiotic that acts bactericidal to gram-negative and gram-positive microorganisms (Pasteurella spp., Salmonella spp., E.coli., Klebsiella spp., Haemophilus spp., Brucella spp., Shigella spp., Mycobacterium spp.)



Slaughter of animals for meat is allowed respectively in 35 days (pigs) and 49 days (cattle). 



Keep in a dry, dark place inaccessible for children at temperatures of 10 °C up to 25 °C.
