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.
