Structuring Nanocarriers for Site Directed Drug Delivery
Suresh P Vyas, Professor, Dr Harisingh Gour University
Conventional drug molecules are often associated with low water
solubility, off-target side-effects, speedy clearance from circulation and
cytotoxicity. To surmount these limitations, number of multifunctional
nanocarriers has been proposed to augment drug delivery. In concept, multifunctional
nanocarriers might be controlled release, biodegradable and may be target
oriented for drug delivery; however, many challenges are to be faced off during
the fabrication of these particles at the stage of pharmaceutical development.
As a promising solution to improve these nanoparticles, they are appropriately
engineered. These structurally modified nanoparticulate systems are
specifically controlled in size and structure and can provide precise scaffolds
over sites for chemical attachment of drugs. These drug delivery cargoes are
typically nanotechnology-based carrier systems that might put forth the
activity of potent bioactive compounds at a pre selected target site, ensuring
their effectiveness and safety in the clinical use.
