: Cubosomes are highly stable nanostructured liquid crystalline dosage delivery form derived from amphiphilic lipids and polymer-based stabilizers converting it in a form of effective biocompatible carrier for the drug delivery. The delivery form comprised of bicontinuous lipid bilayers arranged in three dimensional honeycombs like structure provided with two internal aqueous channels for incorporation of number of biologically active ingredients. In contrast liposomes they provide large surface area for incorporation of different types of ingredients. Due to the distinct advantages of biocompatibility and thermodynamic stability, cubosomes have remained the first preference as method of choice in the sustained release, controlled release and targeted release dosage forms as new drug delivery system for the better release of the drugs. As lot of advancement in the new form of dosage form has bring the novel avenues in drug delivery mechanisms so it was matter of worth to compile the latest updates on the various aspects of mentioned therapeutic delivery system including its structure, routes of applications along with the potential applications to encapsulate variety drugs to serve health related benefits.

The rapid prototyping (RP) technology has advanced in various fields such as verification of design, and functional test. Recently, researchers have studied bio-materials to fabricate functional bio-RP parts. In this research, a nano composite deposition system (NCDS) was developed to fabricate three-dimensional functional parts for bio-applications. In the hybrid process, the material removal process by mechanical micro machining and/or the deposition process are combined. NCDS uses biocompatible or biodegradable polymer resin as matrix and various bioceramics to form bio-composite materials. To test drug release rate in vivo environment, two different types of drug delivery system (DDS) were fabricated using the bio-composite materials. 1) Container type DDS used poly(DL-lactide-co-glycolide acid)(50:50) and 5-fluorouracil as the drug composite while polycaprolactone(PCL) served as the container of the drug. 2) Scaffold type DDS formed porous microstructure with poly(DL-lactide-co-glycolide acid)(50:50) and 5-fluorouracil composite. The effect of geometry of the DDS on release rate of drug is under investigation.

Hydrogels possess three-dimensional polymeric network structure and equipped for retaining extensive measure of water or organic fluids. This quality makes them as exceptional candidate for the simulation of extra cellular matrixes. For this the three dimensional printing (3DP) has evolved as the technique for the formation of the digital models. The 3DP is capable for processing the prescriptions and the therapeutic gadgets. One of the technique known as stereolithographic (SLA) printing has shown promising results in formulating the hydrogel based system for fabrication. The SLA acts by cross connecting the saps to shape the polymer matrices. Due to water captured in the gels it is conceivable to create the pre- wetted, medicate hydrogels and gadgets. The 3DP helps in formation of tailor made drug delivery system as per needs of patients. Many of Bioinks has been tried up for the hydrogel formation such as collagen, gelatin, hyaluronan, silk, alginate, and nanocellulose etc. Keywords: 3D Printing, Hydrogel, Steriolithography

The method of applying prescription dosage forms to the skin for direct treatment of a cutaneous disorder is known as a topical drug delivery system. Topical gels are semisolid dosage forms in which a liquid phase is constrained within a three-dimensional polymeric matrix derived from natural or semi-synthetic sources with high physical or chemical cross-linking. Because of their intermediate behavior between solid and liquid materials, topical gels are an excellent candidate for transdermal drug delivery. Clinical evidence indicates that topical gel is a safe and effective treatment choice for the management of skin-related diseases, especially when used for local action to avoid the side effects of other conventional dosage forms. Gels, cream, ointment, and paste are the most commonly used semi-solid formulations for topical drug delivery. Gels are colloids in which the liquid medium has thickened to the extent that it behaves like a solid. Since topical gel formulations are less greasy and can be quickly removed from the skin, they offer better drug delivery. In comparison to cream, ointment, and paste, gel formulations have improved application properties and consistency. This article aims to review the principles and recent developments in topical gels, including classification, methods of preparation, applications, and so on.
