CFAs (primarily cetyl myristoleate, cetyl oleate, cetyl palmitoleate) incorporate into cell membrane phospholipid bilayers, displacing arachidonic acid and altering the substrate availability for COX-2 and 5-LOX enzymes. This reduces prostaglandin E2 and leukotriene B4 production at the membrane level. Topically, CFAs also act as penetration enhancers and joint lubricants, they physically integrate into synovial membranes. The cetyl ester linkage makes these fatty acids resistant to β-oxidation, so they persist in membranes longer than free fatty acids.
No significant drug interactions identified. CFAs are chemically inert esterified fatty acids with minimal systemic absorption from topical application and low-dose oral use.
