The structure and function of the skin details the individual components of the epidermis, dermis, and their roles in normal skin health. The individual cell types in the epidermis, the different epidermal layers, and the roles of the keratinocyte are explained. The epidermis and dermis, and their important relation to each other through the dermoepidermal junction are described. The dermal adnexal structures of hair follicles (pilosebaceous units), sweat glands, and nerves are all considered. The functions of skin and barrier function are also listed. Rare but important causes of disordered sweating (hyperhidrosis and hypohidrosis) are described. In addition, presentations of hyperhidrosis are discussed.

The International Journal of Pharmaceutics is the journal for pharmaceutical scientists concerned with the physical, chemical and biological properties of devices and delivery systems for drugs, vaccines and biologicals, including their design, manufacture and evaluation. This includes evaluation of the properties of drugs, excipients such as surfactants and polymers and novel materials. The journal has special sections on pharmaceutical nanotechnology and personalized medicines, and publishes research papers, reviews, commentaries and letters to the editor as well as special issues.

A review on chitosan and chitosan-based bionanocomposites: Promising material for combatting global issues and its applications.

(57) Abstract: device for administering a drug by spraying the contents of the container (1) made of plastic material. The apparatus pair of members (23, 23 ') comprises, is supported the container (1) is in the meantime, these members (23, 23') has a first position that is not compressed to the extent that the container (1) ruptures When a relatively movable between a second position which can be members (23, 23 ') exerts sufficient pressure to discharge the contents of the container to rupture the container (1) from the discharge port.

Current trends in polymer microneedle for transdermal drug delivery.

Transdermal drug delivery system through polymeric microneedle: A recent update

Background Blood-brain barrier (BBB) plays a most hindering role in drug delivery to the brain. Recent research comes out with the nanoparticles approach, is continuously working towards improving the delivery to the brain. Currently, polymeric nanoparticle is extensively involved in many therapies for spatial and temporal targeted areas delivery. Methods We did a non-systematic review, and the literature was searched in Google, Science Direct and PubMed. An overview is provided for the formulation of polymeric nanoparticles using different methods, effect of surface modification on the nanoparticle properties with types of polymeric nanoparticles and preparation methods. An account of different nanomedicine employed with therapeutic agent to cross the BBB alone with biodistribution of the drugs. Results We found that various types of polymeric nanoparticle systems are available and they prosper in delivering the therapeutic amount of the drug to the targeted area. The effect of physicochemical properties on nanoformulation includes change in their size, shape, elasticity, surface charge and hydrophobicity. Surface modification of polymers or nanocarriers is also vital in the formulation of nanoparticles to enhance targeting efficiency to the brain. Conclusion More standardized methods for the preparation of nanoparticles and to assess the relationship of surface modification on drug delivery. While the preparation and its output like drug loading, particle size, and charge, permeation is always conflicted, so it requires more attention for the acceptance of nanoparticles for brain delivery.

Polymeric Nanoparticles for Brain Drug Delivery - A Review

Ongoing progression in nanotechnology has demonstrated that nanoparticles have indicated promising potential as in delivering the drug. The acceptance of nanoparticles and their applications also reported in clinical advancement to upgrade and improve the pharmacokinetic and pharmacodynamics properties of therapeutic compounds. In this review, we talk about the next-generation core-shell nanostructures like lipid-polymer hybrid nanoparticles (LHNPs) and their application and formulation aspects. Conceptually, derived from both polymeric nanoparticles and liposome, which gave them a name of hybrid nanoparticles. It is basically polymer core enveloped by a lipid layer. The major issue arises with nanoparticles with polymer is related to entrapment efficiency and LHNPs have proved to solve this issue to a vast extent, due to their hybrid components.

A Review on Lipid- Polymer Hybrid Nanoparticles and Preparation with Recent Update

Andrographis paniculata is a well-known Asian medicinal plant with a major phytoconstituent of diterpene lactones, such as andrographolide, 14-deoxyandrographolide, and neoandrographolide. A World Health Organization (WHO) monograph on selected medicinal plants showed that A. paniculata extracts and its major diterpene lactones have promising anti-inflammatory, antidiabetic, antimalarial, anticancer, antifungal, antibacterial, antioxidant, and hypoglycemic activities. However, these active phytochemicals have poor water solubility and bioavailability when delivered in a conventional dosage form. These biological barriers can be mitigated if the extract or isolated compound are delivered as nanoparticles. This review discusses existing studies and marketed products of A. paniculata in solid, liquid, semi-solid, and gaseous dosage forms, either as an extract or isolated pure compounds, as well as their deficits in reaching maximum bioavailability. The pharmaceutics and pharmacological activity of A. paniculata as a nano-delivery system are also discussed.
