Poorly Water Soluble Drug

The 3D printing techniques have been explored extensively in recent years for pharmaceutical manufacturing and drug delivery applications. The current investigation aims to explore 3D printing for the design and development of a nanomedicine-based oral solid dosage form of a poorly water-soluble drug. A self-nanoemulsifying tablet formulation of dapagliflozin propanediol monohydrate was developed utilizing the semisolid pressure-assisted microsyringe (PAM) extrusion-based 3D printing technique. The developed formulation system consists of two major components (liquid and solid phase), which include oils (caproyl 90, octanoic acid) and co-surfactant (PEG 400) as liquid phase while surfactant (poloxamer 188) and solid matrix (PEG 6000) as solid-phase excipients that ultimately self-nanoemulsify as a drug encapsulated nanoemulsion system on contact with aqueous phase/gastrointestinal fluid. The droplet size distribution of the generated nanoemulsion from a self-nanoemulsifying 3D printed tablet was observed to be 104.7 ± 3.36 nm with polydispersity index 0.063 ± 0.024. The FT-IR analysis of the printed tablet revealed that no drug-excipients interactions were observed. The DSC and X-RD analysis of the printed tablet revealed that the loaded drug is molecularly dispersed in the crystal lattice of the tablet solid matrix and remains solubilized in the liquid phase of the printed tablet. SEM image of the drug-loaded self-nanoemulsifying tablets revealed that dapagliflozin propanediol monohydrate was completely encapsulated in the solid matrix of the printed tablet, which was further confirmed by SEM-EDS analysis. The in vitro dissolution profile of dapagliflozin-loaded self-nanoemulsifying tablet revealed an immediate-release drug profile for all three sizes (8 mm, 10 mm, and 12 mm) tablets, exhibiting >75.0% drug release within 20 min. Thus, this study has emphasized the capability of the PAM-based 3D printing technique to print a self-nanoemulsifying tablet dosage form with an immediate-release drug profile for poorly water-soluble drug.

Aloe-Vera or Aloe barbadensis (botanical name) is a plant with many medicinal properties and have great importance in Ayurveda. Its leaves are succulent, erect, forming a thick rosette. The internal translucent pulp of Aloe-Vera is bound to a waxy crust or cuticle, and its vascular tissues transport minerals as well as water from the soil. Aloe Vera is being used as a major skin rejuvenating product, although it has varied medicinal properties also. In the present study, an attempt to make a method to create bi-layer tablets of Aloe-Vera, utilizing 3D printing techniques is presented. The method created doesnt affect the integral functional characteristics of the tablet. The method here contains creating an immediate release and sustained release tablet for making the Aloe-Vera to be used directly by the person for its numerous health effects. The tablet is designed so to be consumed by vegans as well since it is completely herbal.

Delphinidin is a known dye and food colorant along with many medicinal properties for instance anti-inflammatory, anti-microbial, anti-diabetic, anti-obesity and anti-cancer. The present research has been designed to formulate bi-layered tablets using delphinidin which inherits these medicinal properties. The extrusion of tablets is done by using 3D printing techniques involving a table-top 3D printer which extrudes delphinidin tablets along with the required excipients. The characteristics of the whole tablets have been analyzed separately including hardness, friability, and weight. Adapted method for tablet formulation results in tablets which are appropriate for the immediate release and sustained release. The present research provides a method to make the effective tablets with reduced cost which can be used as drug formulation method in pharmaceutical industries.

Epigallo-catechin Gallate (or EGCG) is a polyphenol which is withdrawn from green tea and is commercially available as Epigallocatechin gallate. Epigallo-catechin gallate is known to have been used as dye and food colorants, but it also has many medicinal properties like anti-inflammatory, anti-microbial, anti-diabetic, anti-obesity, and anti-cancer. Keeping these medical properties in mind, in the present research paper, a 3D printing technique evolving a desktop based 3D printer to extrude tablets along with the active drug ingredient and other excipients that are used as binders and disintegrants. The method adapted in the formulation of a3D printed tablet in this research makes the tablet suitable for immediate and sustained release and does not affects it’s certain physical and mechanical properties such as hardness, friability, and weight variation. The tablets which are extruded from the 3D printer are the bi-layer tablets with controlled release. With the involvement of the 3D printer, the cost of printing the bi-layered tablets have found to be very low which makes the method cost efficient. The output bi-layer tablet has been developed using various analysis and specified standard apparatus and method so that the set standards of the tablet does not get affected. The immediate release and the sustained release methods were studied separately. The final stage of the research completes when the 3D printed tablets with set time intervals for the initial and sustained release and without changing the set mechanical properties of the tablet are obtained.
