Sulfonamides have a broad antibacterial spectrum and have certain inhibitory effects on most Gram-positive and negative bacteria, but different sulfonamides have different antibacterial effects. With the wide application of sulfa drugs, drug-resistant strains will also be easily formed, especially Staphylococcus aureus has more opportunities to develop drug resistance. Sulfonamides can be classified into two categories according to their absorption after oral administration. The first category is easily absorbed sulfonamides, which are characterized by fast absorption. Generally, the blood concentration of sulfonamides is 2 to 4 hours after taking the drug (after 5 hours for long-acting drugs). The peak can be reached, and this type of sulfonamides is mainly used for systemic infections. The other type is not easily absorbed or absorbed very little after oral administration, and most of them are excreted through the intestinal tract, mainly used for intestinal infections. Sulfamethoxazole, also known as sulfamethoxazole, is a broad-spectrum antibacterial drug that has a particularly strong effect on Staphylococcus and Escherichia coli, and is used to treat urinary tract infections and avian cholera. Sulfamethoxazole is a systemic medium-acting sulfonamide drug, which can compete with PABA to act on the dihydrofolate synthase in bacteria, preventing the synthesis of bacterial dihydrofolate, thereby inhibiting the growth and reproduction of bacteria. Together with sulfadiazine, sulfisoxazole and trisulfadiazine, three sulfa drugs are currently the best drugs for the treatment of nocardiosis. Half-life of 10 to 12 hours, can be partially acetylated.
