It is oxidized in the body to phenobarbital and phenethyl malonamide, which have anti-epileptic activity. Its anti-epileptic effect is similar to that of phenobarbital, but its intensity and toxicity are lower. It is rapidly and completely absorbed orally, reaching the peak plasma concentration in about 3 hours. The half-life is about 8 hours, and the plasma protein binding rate is 20%. It can easily pass through the blood-brain barrier, the placenta, and appear in breast milk. At therapeutic concentrations, it can reduce the excitatory effect of glutamate, enhance the inhibitory effect of gamma-aminobutyric acid, inhibit monosynaptic and polysynaptic transmission of the central nervous system, lead to a decrease in the excitability of the entire nerve cell, and increase the electrical stimulation threshold of the motor cortex. It can increase the threshold of seizures and inhibit the spread of discharges of epileptic foci.

This product is a fluoroquinolone antibacterial drug with a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacteria. It acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death. It has effects on both Gram-positive and Gram-negative bacteria. Bacteria are not easy to develop resistance to this product, and there is no cross-resistance between similar drugs and antibiotics.

By inhibiting the synthesis of prostaglandins and other effects, it can eliminate and reduce the activity of pain factors in multiple targets and in an all-round way, thereby achieving the effect of quickly relieving headaches and neuralgia. It can also achieve antipyretic effect by regulating the hypothalamic temperature regulation center; it can synergize with caffeine to enhance the analgesic effect.

Enhance the analgesic effect. Small doses of caffeine can enhance the excitation process of the cerebral cortex, invigorate the spirit, and effectively improve symptoms such as fatigue, discomfort, and lack of energy caused by headaches and neuralgia.

Neurotrophic drugs can improve the activity of nerve tissue, enhance nerve nutrition, promote the metabolism of nerve tissue, and restore its normal physiological function. They have a good therapeutic effect on neurasthenia and memory loss caused by other reasons.

The antibacterial property is similar to that of erythromycin. It has a strong antibacterial effect on Gram-positive bacteria, and is effective against Staphylococcus, Streptococcus pyogenes, Streptococcus viridans, Streptococcus pneumoniae, Diphtheria bacillus, Tetanus bacillus, and anthrax bacillus. It also has antibacterial effects on Gram-negative bacteria such as gonococci and pertussis bacillus. It is also effective against Leptospira, Rickettsia, and Mycoplasma. It can be used as a substitute for erythromycin for infections of the oropharynx, respiratory tract, skin and soft tissue, and bile duct caused by the above-mentioned sensitive bacteria.
