Sulfamethoxazole is a man-made synthetic antibiotic in the group called Sulfonamides – sulfa drugs. These drugs are broad spectrum bacteriostatic antibiotics – they stop the growth of bacteria but don’t necessarily kill them. Once the drug is removed, the microbe can resume growth.<\/p>\n\n\n\n
The mode of action for sulfamethoxazole is inhibition of folic acid synthesis by binding to (and thus inhibiting) a key enzyme in the pathway. Folic acid (vitamin B9) is a critical co-factor used by numerous enzymes for biological reactions, including nucleic acid synthesis and repair. Bacteria that cannot make their own folic acid must have a means for acquiring it from their environment; those that can are resistant to sulfa drugs while those that can’t are killed.<\/p>","protected":false},"excerpt":{"rendered":"
