Nano- and Microfabrication Techniques in Drug Delivery

Abstract

Nasal drug delivery is a current drug delivery trend that is gaining attraction, especially for respiratory and central nervous system (CNS) diseases. This delivery pathway avoids the undesirable effects of systemic drug delivery, such as excessive dosing, damage to non-diseased organs, or drug destruction before reaching the therapeutic target. Inhaled drugs have been used for therapeutic and recreational purposes since ancient times. The development of modern inhalers for drug delivery has increased the use of intranasal drugs. More than ever, the development of drug-integrated intranasal formulations is extremely promising, providing hope for the treatment of diseases previously thought to be difficult to treat, such as tuberculosis or central nervous system diseases. Numerous investigations of intranasal formulations have been studied and published by pharmacologists over the years. The majority of research products are nanocapsules such as nanoparticles, micelles, liposomes, sol-gels, emulsions, and microspheres. Targeted drug formulations are created based on the features of the disease, the cell’s characteristics, the nature of the cell environment, and the biochemical barriers that the drug has to overcome. Preclinical and clinical assays of drug formulations help to determine their applicability in patients by the examination of their physicochemical properties, drug release, and pharmacokinetics. In this review, we focus on the factors that influence the nasal drug delivery, as well as drug release in the studies of tuberculosis and CNS formulations.
