Meclofenoxate is frequently used in clinical practice in several ways: oral tablets, intravenous and intramuscular injections. The effects of meclofenoxate are mainly central nervous system stimulants, promoting brain metabolism, scavenging free radicals in the brain, increasing blood flow in the brain, as well as anti-hypoxic effects, improving the patient’s memory capacity, and therefore, it is more useful for patients experiencing drowsiness, lethargy, coma, and also patients with impaired consciousness. Meclofenoxate can increase the level of 5-hydroxytryptamine in the brain, which can enhance brain excitability, thus reducing the incidence of Alzheimer’s disease as well as delaying aging. However, it should be noted that certain systemic diseases, such as hyperexcitability, extrapyramidal and hypertensive patients should not use it, as it can easily cause hyperexcitability manifestations.
