The transmembrane rather than paracellular transport of lipophilic compounds was supported by the demonstration of an inverse association between lipid/water partition coefficient and increased transport rate following calcium chelation, i.e., disrupting intercellular junctions increased the transport of hydrophilic but not of lipophilic small organic molecules [31]
Even where compounding becomes permitted, it does not mean these peptides are FDA-approved drugs
