The Introductction of Trimethoprim :
Trimethoprim is a lipophilic alkaline pyrimethamine bacteriostatic, white or white crystalline powder at room temperature, odorless, bitter taste, slightly soluble in chloroform, slightly soluble in ethanol , almost insoluble in water, soluble in glacial acetic acid. Antibacterial spectrum and sulfonamides similar, but strong antibacterial effect, E. Coli, Proteus Mirabilis, pneumonia, Staphylococcus saprophyticus, a variety of gram-positive and negative bacteria, but not for PSEUDOMONAS AERUGINOSA infection, the minimal inhibitory concentration (mic) was usually lower than 10mg/l. The drug resistance of the bacteria could be easily induced by single use, it is clinically used to treat urinary tract infection, intestinal tract infection, respiratory tract infection, bacillary dysentery, enteritis, typhoid fever, meningitis, otitis media, meningoencephalitis, epidemic encephalitis, septicemia and soft tissue infection. For typhoid fever, paratyphoid fever efficacy is not less than Ampicillin, can also be combined with long-acting sulfa drugs for drug-resistant Falciparum malaria control.
The Application & Function of Mebendazole :
1. Antibacterial synergist, used solely for respiratory tract infection, urinary tract infection, intestinal infections, and other conditions. It can also treat poultry bacterial infections and coccidiosis.
2. Preferred as antimicrobial agents, Dihydrofolate reductase inhibitors with procaryotic enzyme selectivity; specific dosage forms inhibitors, widely used in Dihydrofolate reductase; Inhibition of Tetrahydrofolic acid synthesis by prokaryote-specific Dihydrofolate reductase.
