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.

The aim of study was to develop self-nanoemulsifying systems of poorly water-soluble drug repaglinide, which is an antidiabetic drug in the class of medications known as meglitinides. Solubility of repaglinide in oily phases and surfactants was determined to identify components of self-nanoemulsifying drug delivery system (SNEDDS). Surfactants and oil was selected based on solubility studies were further screened for their efficiency in formulation. Acrysol K 150, Kolliphor EL and Capmul MCM were selected as oil, surfactant and co-surfactant respectively. Formulation F8 was found to be optimized formulation on the basis of in vitro dissolution studies, particle size and zeta potential. The optimized formulation was then subjected to stability studies and was found to be stable after 6 months. Thus, SNEDDS were found to be influential in improving the release performance of repaglinide, indicating their potential to improve the solubility and oral bioavailability of repaglinide.

Poorly Water Soluble Drug

Amorphous solid dispersions (ASDs) improve the oral delivery of poorly water-soluble drugs. ASDs of olanzapine (OLZ), which have a high melting point and low solubility, are performed using a complicated process. Three-dimensional (3D) printing based on hot-melt pneumatic extrusion (HMPE) is a simplified method for producing ASDs. Unlike general 3D printing, printlet extrusion is possible without the preparation of drug-loaded filaments. By heating powder blends, direct fused deposition modeling (FDM) printing through a nozzle is possible, and this step produces ASDs of drugs. In this study, we developed orodispersible films (ODFs) loaded with OLZ as a poorly water-soluble drug. Various ratios of film-forming polymers and plasticizers were investigated to enhance the printability and optimize the printing temperature. Scanning electron microscopy (SEM) showed the surface morphology of the film for the optimization of the polymer carrier ratios. Differential scanning calorimetry (DSC) was used to evaluate thermal properties. Powder X-ray diffraction (PXRD) confirmed the physical form of the drug during printing. The 3D printed ODF formulations successfully loaded ASDs of OLZ using HMPE. Our ODFs showed fast disintegration patterns within 22 s, and rapidly dissolved and reached up to 88% dissolution within 5 min in the dissolution test. ODFs fabricated using HMPE in a single process of 3D printing increased the dissolution rates of the poorly water-soluble drug, which could be a suitable formulation for fast drug absorption. Moreover, this new technology showed prompt fabrication feasibility of various formulations and ASD formation of poorly water-soluble drugs as a single process. The immediate dissolution within a few minutes of ODFs with OLZ, an atypical antipsychotic, is preferred for drug compliance and administration convenience.

Liquisolid technology is very effective technique for improving the solubility and dissolution properties of poorly water soluble drug formulations like Clotrimazole. Clotrimazole is a BCS Class II, antifungal drug used for treatment for Vaginal Candidiasis.  In this liquisolid technique the drug soluble in non volatile solvents and then it converted into free flowing, non adherent powder, which can be compressed into tablet. Here N-methyle-2-pyrrolidone and propylene glycol is used in the ratio of 1:1 as a solvent. Neusilin US2 and Aerosil 200 used as Coating and Carrier material respectively. For mucoadhesion on vaginal wall Sodium carboxymethyle cellulose used as a mucoadhesive agent. Mucoadhesive tablets were prepared using direct compression technique. Magnesium Stearate used as a glidant. Mucoadhesive liquisolid tablets were evaluated as precompression evalutions and post compression evaluations. Future tablets were evaluated as In vitro and Ex vivo evaluations. The optimized batch showed that In vitro release in simulated vaginal fluid pH 4.5 in 6 hr was 99%. Ex vivo diffusion studies of optimized batch showed 80% of drug diffusion in 6 hr. Mucoadhesive strength showed high mucoadhesion of optimized batch that is 36 gm. From this study it was concluded that liquisolid technology is an effective technique to improve solubility and dissolution properties of poorly water soluble drug formulations like Clotrimazole.
