Contain:

Each tablet contains: Sulfamethoxazole 400 mg, trimethoprim 80 mg and excipients to 600 mg.  Available in packs of  20 tablets, packed blisters containing 10  tablets..

Mode of action:
In combination, the two active constituents have a bactericidal activity against most gram-positive and gram-negative pathogenic bacteria.  The combination acts by inhibiting sequential steps in the biosynthetic pathway that is used by micro-organisms in their synthesis of folate cofactors.  Sulphadiazine inhibits the incorporation of para-aminobenzoic acid (PABA) into folic acid and Trimethoprim inhibits the enzyme dihydrofolate reductase, which converts dihydrofolic acid into tetrahydrofolic acid.

Indications:
For treatment of infections of the respiratory tract, urogenital tract and alimentary tract, the gallbladder and biliary tract, skin, soft tissue and bone, general septicemic conditions, toxoplasmosis, coccidiosis and other diseases in dogs and cats, caused by sulphadiazine / trimethoprim-sensitive micro-organisms and protozоа.

Contraindications:

Do not use in animals with a hypersensitivity to sulfonamides, trimethoprim, or to any of the excipients. Do not use in animals with severe hepatic or renal impairment
