Dextromethorphan D6 is a weak uncompetitive antagonist of the NMDA receptor. Dextromethorphan is also acts at nicotinic receptors, sigma-1 rcptor and serotonin and norepinephrine transporters. The incorporation of deuterium serves to reduce dextromethorphan first-pass liver metabolism. AVP-786 is an oral formulation of a combination of deuterated (d6)-dextromethorphan and an ultra-low dose of quinidine. Avanir Pharmaceuticals launched a phase III development program of AVP-786 for the treatment of agitation in patients with Alzheimer's disease.

Menthyl lactate is derived from menthol, a compound that comes from peppermint oil, or is made synthetically. Menthol has a natural cooling effect, which makes it useful as a topical analgesic to treat skin irritation, pain, itching or sunburn. Despite its cooling benefits, menthol can be a skin irritant. Like menthol, menthyl lactate is cooling, but it causes less skin irritation than menthol. Menthyl lactate also has a refreshing, minty taste. For this reason, some manufacturers use it as a flavoring ingredient. The compound is recommended for use as a flavor in concentrations of 0.005% to 0.2% and in cosmetic and other external products in concentrations ranging from 0.2% to 2.0%. Menthyl lactate is a known compound available e.g. from Haarmann & Reimer GmbH (Germany) under the name FRESCOLAT, Type ML.
