Lomerizine Hydrochloride Tablets

Pharmacological action: This product is a diphenylpiperazine calcium channel blocker with selective cerebral vasodilation. Toxicological study: Genetic toxicity: The results of microbial reverse mutation test, chromosome aberration test and mouse micronucleus test were all negative. Reproductive toxicity: The non-toxic dose for male rat fertility is 100 mg/kg/day, and that for female rats is 30 mg/kg/day. The rat fetal organogenesis toxicity test showed that in the female rats with a dose of more than 10 mg/kg/day, abnormal delivery and decreased birth rate of young rats were observed; in the 30 mg/kg/day dose group, maternal vaginal bleeding, weight gain inhibition and reduced food intake were observed, the number of fetal deaths increased, weight loss and abnormal appearance with finger loss as the main manifestation were observed. The non-toxic dose for mother rats, fetuses and postnatal rats was 3 mg/kg/day. The results of the rabbit fetal organogenesis toxicity test showed that the administration of 5, 15 and 45 mg/kg/day dose groups had no significant effect on maternal animals. In the 45mg/kg/day group, the fetal mortality rate increased, the survival rate decreased, and no teratogenic effect was observed. The safe dose for pregnant rabbits is 45mg/kg/day, and for rabbit fetuses it is 15mg/kg/day. The results of toxicity tests on rats during the perinatal and lactation periods showed that the 30mg/kg/day dose group showed inhibition of maternal weight gain and delivery disorders. At the same time, the pups in the same group showed deterioration of general condition, weight loss, and decreased survival rate due to poor lactation. During lactation, the pups given doses of 10mg/kg/day or more showed a tendency to have low body weight and a low completion rate of auricle separation. The safe dose for perinatal and lactation mothers is 10mg/kg/day, and for pups it is 3mg/kg/day.

1. Use with caution in patients with severe liver function loss (this product is mainly metabolized by the liver and excreted through the bile, and patients with severe liver damage will maintain high blood concentrations); 2. Use with caution in patients suspected of QT interval prolongation (ventricular arrhythmia, QT prolongation syndrome, hypokalemia, hypocalcemia); 3. Use with caution in patients with parkinsonism (similar compounds have been reported to cause extrapyramidal symptoms, so this product will worsen the symptoms); 4. Use with caution in patients who are in a depressed state or have a history of depression; 5. Use with caution in elderly patients.

Precautions for children: There is no safety data for children. Precautions for pregnancy and lactation: Pregnant women or women who may become pregnant are prohibited. Precautions for the elderly: 1. The dose selection for elderly patients should be very cautious, mainly considering that most elderly patients may have impaired liver function, which will lead to potential safety risks of sustained high blood drug concentration or higher. 2. Similar compounds (such as flunarizine hydrochloride) are prone to cause extrapyramidal symptoms and depression in elderly patients after administration, so during the medication process of elderly patients, the reaction needs to be closely monitored. Once abnormal conditions are found, the administration should be stopped and appropriate treatment methods should be taken.

Concomitant use of antihypertensive drugs can cause an enhanced interaction, leading to lower blood pressure.
