Cefdinir
Function and Efficacy
Antibacterial effect It has a wide antibacterial spectrum against Gram-positive and Gram-negative bacteria, especially against Staphylococcus and Streptococcus among Gram-positive bacteria. It has stronger antibacterial activity than previous oral cephalosporins, and its mode of action is bactericidal. It is stable to β-lactamase produced by various bacteria, and also has excellent antibacterial activity against β-lactamase producing bacteria. The mechanism of action is to prevent the synthesis of bacterial cell wall. It has strong affinity for penicillin binding protein (PBP) 1 (1a, 1bs), 2, and 3, but the active sites for different bacteria are different.

Drug Interactions
Caution is required when using this product with the following drugs. Drug signs, symptoms, treatment mechanisms and risk factors Iron preparations may reduce the absorption of cefdinir by about 10%, so it is recommended to avoid co-administration with such drugs. If co-administration cannot be avoided, the interval between the two doses should be greater than 3 hours This product can combine with iron ions in the intestine to form a complex that is difficult to absorb. Warfarin potassium The effect of warfarin potassium may be enhanced, but there are no reports of interaction between the two. This product may inhibit the production of vitamin K by intestinal bacteria. Antacids (containing aluminum or magnesium) can reduce the absorption of cefdinir and weaken its effect, so antacids should be used 2 hours after taking this product. The mechanism is not clear.
Storage
Keep in a dark place (avoid light and not exceed 20℃) and sealed.
