Emerging Drug Technologies

3D Printing in Pharmaceuticals

3D printing, also referred as the technique of additive production, is being recognized as a groundbreaking technology in the pharmaceutical sector. It allows for the precise and customizable production of drug dosage forms & Drug delivery systems. This technology builds three-dimensional structures layer by layer, providing innovative prospects for advanced medication delivery and tailored therapeutics.⁶

Technologies of 3D Printing

In the pharmaceutical sector, three key 3D printing technologies are commonly utilized.

Fused Deposition Modelling (FDM)

Works by extruding thermoplastic filaments in successive layers, making it particularly suitable for producing solid oral dosage forms which include tablets and capsules.⁷

Stereolithography (SLA)

Uses a Ultra-violet laser to cure liquid resin, resulting high accuracy and flawless surface finishes, which are perfect for fabricating complicated drug delivery devices.⁷

Selective Laser Sintering (SLS)

Its has a laser to fuse pulverized materials, allowing the fabrication of robust components, including drug delivery systems, implants, and tissue scaffolds.⁷

Each of these 3D printing methods is selected for its unique advantages, playing a vital role in shaping the growth of personalized drug forms and advanced pharmaceutical components. Let us briefly explore each technology.

Fused Deposition Modelling

Fused Deposition Modelling (FDM), also called as Fused Filament Fabrication (FFF), has been widely investigated for use in pharmaceutical applications.In this method, a thermoplastic polymer filament is constantly supplied through a heated nozzle, where it is melted just above its glass transition temperature. The melted material is then accurately deposited layer by layer on a substrate and let it cool, forming the desired 3D object.This extrusion-based technology is highly versatile and can utilize a variety of materials, including pastes, polymers, silicones, suspensions, and semisolids.However, in FFF applications, solid polymer filaments are primarily used to create geometrically designed drug delivery systems with customized release profiles, scaffolds, and drug-eluting devices.⁸

Hot melt extrusion (HME) is a key technique for producing continuous filaments from thermoplastic polymers for use in FDM printing. Commonly used thermoplastic polymers, which are considered safe for pharmaceutical applications, consist of ethylene vinyl acetate (EVA), polylactic acid (PLA), polyvinyl acetate (PVA), and acrylonitrile-butadiene-styrene (ABS).  Active pharmaceutical ingredients (APIs), which are chosen according to the unique characteristics of the polymers, are frequently combined with the feedstock filaments. These characteristics might include swellable/erodible qualities (like hydroxypropyl methylcellulose or HPMC), enteric qualities (like Eudragit® L 30D55), rapid solubility (like polyvinyl pyrrolidone), or insolubility (like PVA or Eudragit® RL). These tailored filaments are ideal for 3D printing capsules and other dosage forms, whether designed for immediate or controlled release.⁸

A key benefit of HME is its ability to create homogeneous solid dispersions of thermally stable drugs and excipients within the printable filament material—something that is difficult to achieve using other techniques.This process ensures efficient manufacturing with minimal material waste.FDM is a desirable alternative for developing pharmaceutical formulations because it may modify drug loading and release patterns by altering the feedstock composition or the geometric design.⁹

There have also been efforts to establish a standardized qualification framework for FDM printers, which could streamline procedure for approval of newly developed 3D-printed pharmaceutical products.

Crispr Technology

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a groundbreaking gene-editing technology that enables exact changes to an organism’s DNA.Originally discovered as a natural defence mechanism in bacteria and archaea against viruses, CRISPR consists of two primary components: the Cas9 protein, which functions as molecular scissors, and a guide RNA (gRNA), which directs the Cas9 protein to the specific DNA sequence targeted for editing.The gRNA is designed to complement the target DNA sequence, and once Cas9 reaches the target, it creates a double-strand break in the DNA.The cell’s inherent repair processes then take over, either introducing the desired changes through non-homologous end joining (NHEJ) or facilitating accurate edits via homology-directed repair (HDR).²⁴

CRISPR has transformed genetic research, enabling gene modifications with remarkable precision and ease.Its applications span medicine, agriculture, and biotechnology, empowering scientists to explore gene functions, develop therapies for genetic disorders, and improve crop resilience to pests and environmental stressors.²⁴Despite its vast potential, CRISPR raises ethical and safety concerns, especially in human germline editing and the possibility of off-target effects, sparking ongoing discussions about its regulation and responsible use.²⁵
