Abstract

Hydrophilic drugs are preferred candidates for most routes of drug administration, because of their enhanced solubility and dissolution under aqueous in vivo conditions. However, their hydrophilic nature also leads to decreased permeability across hydrophobic barriers. This is a severe limitation in situations where membrane permeability is the primary factor affecting bioavailability and efficacy of the drug. Highly impermeable cellular membranes or the tight endothelial junctions governing the blood-brain barrier are prime examples of this limitation. In other cases, decreased permeability across mucosal or epithelial membranes may require increased doses, which is an inefficient and potentially dangerous workaround. Covalent conjugation of hydrophilic drugs to hydrophobic moieties like short-chain lipids is a promising strategy for maintaining the critical balance between drug solubility and permeability. This article practically focuses on the production procedure of Lipid drug conjugates (LDCs), various formulation methodologies for preparing LDC nanoparticles with detailed about their in vitro physicochemical characterization at laboratory scale. Moreover, brief overviews on the role of LDCs in novel drug delivery applica...Continue Reading

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
