Cephalexin is a first-generation cephalosporin with an antibacterial spectrum similar to that of cephalothin, but its antibacterial activity is poorer than that of the latter. Except for Enterococcus and methicillin-resistant Staphylococci, most strains of Streptococcus pneumoniae, hemolytic Streptococcus, and Staphylococcus aureus that produces or does not produce penicillinase are sensitive to this product. This product has a good antibacterial effect on Neisseria, but Haemophilus influenzae is less sensitive to this product; this product has a certain antibacterial effect on some Escherichia coli, Proteus mirabilis, Salmonella and Shigella. The remaining Enterobacteriaceae, Acinetobacter, Pseudomonas aeruginosa, and Bacteroides fragilis are resistant to this product. Fusobacterium and Veillonella are generally sensitive to this product, and anaerobic Gram-positive cocci are moderately sensitive to this product.

1. It can simultaneously relax the coronary arteries in the normal blood supply area and the ischemic area, antagonize spontaneous or ergonovine-induced coronary artery spasm, increase the delivery of myocardial oxygen to patients with coronary artery spasm, and relieve and prevent coronary artery spasm. 2. It can inhibit myocardial contraction, reduce myocardial metabolism, and reduce myocardial oxygen consumption. 3. It can relax peripheral resistance vessels, reduce peripheral resistance, and can reduce systolic and diastolic blood pressure, reducing cardiac afterload. 4. It can delay the sinus node function and atrioventricular conduction of isolated hearts; electrophysiological studies on whole animals and humans have not found that this product has the effect of delaying atrioventricular conduction, prolonging the recovery time of the sinus node, and slowing down the sinus node rate.
