This product is a semi-synthetic ergot alkaloid derivative. It has α receptor blocking and vasodilation effects. It can enhance the metabolism of brain cell energy and increase the utilization of oxygen and glucose. It can promote the conversion of neurotransmitter dopamine to enhance nerve conduction, strengthen brain protein biosynthesis, and improve brain function. Toxicity tests failed to show that nicergoline has teratogenic effects.

It is a broad-spectrum penicillin antibiotic that kills bacteria by interfering with the synthesis of bacterial cell walls. It is mainly used to treat infections caused by Pseudomonas aeruginosa and various Gram-negative bacilli, but it is easily hydrolyzed by β-lactamase produced by bacteria and produces drug resistance. Combination with sulbactam can enhance the antibacterial effect.

It has an irreversible inhibitory effect on most important β-lactamases produced by β-lactam antibiotic-resistant strains, can prevent resistant bacteria from destroying penicillins and cephalosporins, and has a significant synergistic effect with penicillins and cephalosporins. It has no antibacterial activity against other bacteria except Neisseria and Acinetobacter.

Piperacillin is a broad-spectrum penicillin antibiotic that kills bacteria primarily by interfering with the synthesis of bacterial cell walls. It is mainly used for infections caused by Pseudomonas aeruginosa and various Gram-negative bacilli, but it is easily hydrolyzed by β-lactamases produced by bacteria and develops drug resistance.

Sulbactam has no antibacterial activity against other bacteria except Neisseria and Acinetobacter, but it has an irreversible inhibitory effect on most important β-lactamases produced by β-lactam antibiotic-resistant strains. Sulbactam can prevent the destruction of penicillins and cephalosporins by resistant bacteria, and has a significant synergistic effect with penicillins and cephalosporins.
