1-Ethyl-6,8-difluoro-1,4-dihydro-7- (3-methyl-1-piperazinyl) -4-oxo-3-quinolinecaboylic acid What are the related drug products

1 - Ethyl - 6,8 - difluoro - 1,4 - dihydro - 7- (3 - methyl - 1 - piperazinyl) - 4 - oxo - 3 - quinolinecarboxylic acid, often called enoxacin in Chinese, is a key component of quinolone antibacterial drugs. Related pharmaceutical products, such as enoxacin tablets, oral dosage form, are suitable for a variety of infectious diseases such as urogenital system infections, respiratory tract infections, and gastrointestinal tract infections caused by sensitive bacteria. After the patient takes it orally, the drug is absorbed through the gastrointestinal tract, enters the blood circulation, and then reaches the site of infection, inhibits the activity of bacterial DNA rotatase (bacterial topoisomerase II), hinders bacterial DNA replication, and finally realizes the antibacterial effect.

Another example is enoxacin capsules, which are also used for various infections caused by the above-mentioned sensitive bacteria. The capsule dosage form is convenient for patients to take, and can disintegrate and release the drug in the gastrointestinal tract, exerting antibacterial effect.

Another example is enoxacin injection, which is administered intravenously, allowing the drug to quickly enter the blood circulation and quickly reach the infection focus. For some more serious infections or patients who cannot take oral drugs, it is an effective treatment option.

Although these drugs have significant antibacterial effects, they may also cause adverse reactions, such as gastrointestinal reactions (nausea, vomiting, abdominal pain, etc.), and central nervous system reactions (dizziness, headache, insomnia, etc.). Therefore, when applying them clinically, physicians should choose them based on the patient's specific condition and physical condition, considering the advantages and disadvantages.
