In elderly patients, meclofenoxate has been shown to improve performance on certain memory tests.[5] Meclofenoxate also increases cellular membrane phospholipids.[citation needed] It is sold in Japan and some European countries, such as Germany, Hungary, and Austria, as a prescription drug.

Side effects

edit

Meclofenoxate is considered to be safe and high in tolerability. However, possible side effects may include, rarely, insomnia, dizziness, restlessness, muscle tremor, depression, nausea, muscle tension, and headache; these side effects may be due to overdosage and may indicate the need for the dosage to be reduced.

Research

edit

Meclofenoxate, as well as DMAE, have been found to increase the lifespans of mice by 26.5%.[6][7]

Brand names
