WebThe delivery of drugs to CNS has been constrained due to the presence of blood-brain barrier (BBB). The intranasal route involving several pathways (viz., olfactory, trigeminal, and rostral migratory stream-based pathway) has emerged as potential route to bypass the BBB and transport drug directly to the brain. WebSeveral drug delivery systems already exist for the encapsulation and subsequent release of lipophilic drugs that are well described in the scientific literature. Among these, lipid nanoparticles (LNP) have specifically come up for dermal, transdermal, mucosal, intramuscular and ocular drug administration routes in the last twenty years. tektrol llc
