The Stability

The stratum corneum, the most superficial layer of the skin, protects the body against environmental hazards and presents a highly selective barrier for the passage of drugs and cosmetic products deeper into the skin and across the skin. Nanomaterials can effectively increase the permeation of active molecules across the stratum corneum and enable their penetration into deeper skin layers, often by interacting with the skin and creating the distinct sites with elevated local concentration, acting as reservoirs. The flux of the molecules from these reservoirs can be either limited to the underlying skin layers (for topical drug and cosmeceutical delivery) or extended across all the sublayers of the epidermis to the blood vessels of the dermis (for transdermal delivery). The type of the nanocarrier and the physicochemical nature of the active substance are among the factors that determine the final skin permeation pattern and the stability of the penetrant in the cutaneous environment. The most widely employed types of nanomaterials for dermal and transdermal applications include solid lipid nanoparticles, nanovesicular carriers, microemulsions, nanoemulsions, and polymeric nanoparticles. The recent advances in the area of nanomaterial-assisted dermal and transdermal delivery are highlighted in this review.

Transdermal Drug Delivery System

Transdermal drug delivery system is one of the leading technology which gives extensive benefits compared to other dosage forms. In the case of drugs having a first-pass metabolism problem, small doses of drugs can be delivered. Oral drug delivery is associated with several problems like pain interrelated with the use of injections,needles, and the researchers mainly focus on the development of the transdermal route. The aim is to provide a rationale for improvement of the transdermal system of antipsychotics by highlighting the antipsychotic formulation and safely delivering medications across the skin.The present review emphasis on the latest advances in a transdermal delivery system which acts as a platform for effective transdermal delivery of antipsychotic. By using this technique, the pharmacotherapy of patients who have psychosis can be improved. There are numeral physical methods, and the skin penetration enhancement techniques have been developed that helps in delivering drugs through the skin.This technique helps to alter the barrier properties of skin and improves the penetration of the drug.It majorly highlights the possible role of microneedle in the transdermal system and acts as a different carrier in delivering several therapeutic agents effectively. This article summarizes thenovel transdermal delivery approaches, advantages, and the choice of antipsychotropic drugs.

Application Prospects

Nanocellulose has wide application prospects due to its abundant availability, low price, and biodegradability. In addition, it can address a number of environmental issues. For example, nanocellulose can be used as an alternative to petroleum to reduce environmental pollution. Moreover, nanocellulose has been used as a reinforcing material for food packaging. Improved barrier properties can be obtained when nanocellulose is combined with biopolymers and synthetic polymers. This review briefly introduces three types of nanocellulose and presents the recent advances in barrier property improvement using these three kinds of nanocellulose and their application in food packaging.

Transdermal Penetration

Transdermal delivery offers opportunities for inventive, challenging and valuable research with patient benefits. However, the prominent challenge in designing transdermal drug delivery systems is to overcome the natural transport barrier of the skin, the stratum corneum. Several physical and chemical enhancement techniques have been investigated in the last decade to breach the skin barrier and assist the transport of macromolecules across skin. Recent technological advances in this field include novel combination strategies of penetration enhancement techniques, microneedle array designs, needle-free technologies, nanocarriers, metered dose and microstructured transdermal systems. The present review reports on recent advances in physical approaches towards enhanced transdermal penetration. Enhancement strategies comprehensively covered in this review emphasize the significant achievements gained through successful transdermal delivery of hydrophilic macromolecules, vaccines, proteins, peptides, oligonucleotides, fluorescent dyes and plasmid delivery. Some commercially available technologies for transdermal delivery have also been covered. These novel technologies hold immense potential to advance further into clinical practice and enable better therapeutic applications and prophylactic interventions for various diseases.
