[pharmacological action] this product is a broad-spectrum antibacterial agent, which is effective for most gram-positive bacteria and some gram-negative bacteria, and also effective for the coccidiasis and toxoplasma. sulfadiazine acts on dihydrofolate synthase, which interferes with the first step of folate synthesis. methoxyl benzyl totally belong to antibacterial synergist, folic acid acts on the synthesis of the second step, selective inhibition dihydrofolate reductase role, so the two together can produce synergy, can make the bacteria folic acid metabolism by double block, enhanced antibacterial effect. the effects of sulfa drugs can be metabolized into drugs such as procaine and tetracaine. in addition, the abscess and tissue decomposition products can also provide the necessary substances for bacterial growth and antagonize the sulfonamide drugs.
[drug interaction] (1) contains some of acyl amino benzene armour drugs such as procaine, tetracaine can generate the amino acid in the body, such as yeast contains bacteria needed for amino acid metabolism, can reduce the medicine effect, therefore should not be used.
(2) the use of diuretics such as thiazine or urinates can aggravate renal toxicity.
(3) usually can replacement under high protein binding rate of sulfonamides drugs, such as methotrexate, bute, thiazide diuretic, duly salicylate, probenecid, benzene, although the clinical significance of interaction is not entirely clear, but must be replacement drugs to strengthen monitoring.
(4) the combination of antacids and sulfonamides can reduce their bioavailability.
