How 3D Printing Can be the Future of 3D Printed Pills
Prescribed drugs help millions of people every day with a wide range of health issues. Unfortunately, not all drugs are available in the precise dosage that each individual requires. When it comes to meeting the specific requirements of individual patients, mass production frequently falls short, which might compromise the efficacy and safety of treatment. Because of this shortage, personalized medicine has become more important. This kind of care takes into account the unique characteristics of each patient and uses that information to determine the optimal dosage for each patient.
In response to the rising demand for individualized healthcare, the pharmaceutical industry is actively seeking solutions that eliminate dosage errors, which have a significant impact on treatment effectiveness.
Why is There So Much Demand for Personalized 3D Printed Pills?
For a long time, pharmaceuticals were made with what seems like a "one-size-fits-all" mentality; for example, there was a fixed amount of dosages available for pills and capsules. Now, what if you find that such precise potions are ineffective? When medication comes in predetermined quantities, it could be difficult to avoid taking an excessive or insufficient amount. When using vital medicines like antidepressants, adverse effects might occur from abruptly changing the quantity; therefore, this can have significant repercussions.
In such cases, the conventional wisdom holds that cutting the tablet in half or quarters will yield an intermediate dose. This, however, isn't feasible for all tablets, and even when it is, studies reveal that the dosage is frequently off. With the help of 3D printing, doctors can eliminate guesswork and tailor their treatments to each individual patient.
3D Printing and its Application to Healthcare
A computer-controlled printer builds the 3D model by depositing material in layers. In recent years, there has been a lot of buzz about the potential medicinal uses of 3D printing. An example of this is the use of 3D printing to produce synthetic, laboratory-grown tissues, such as human vaginal and bladder tissues and, more recently, cardiac cells.
This cutting-edge tech will also shake up the pharmaceutical sector. Aprecia Pharmaceuticals' anticonvulsant SPRITAM® (levetiracetam) was the first 3D-printed medicine to receive FDA approval. Compared to drugs made the old-fashioned way, this new formulation has a lot of benefits. The 3D-printed medicine dissolves rapidly in water, the first step.
Seizure patients, especially those in public places where intravenous medicine delivery isn't an option, would surely benefit from the capacity to rapidly receive therapeutic concentrations of an anticonvulsant on board. Plus, the 3D printer allows for the production of the pill at higher doses than what is typically available. Reminding people to take their medication only once daily instead of multiple times could improve drug adherence.
The Emergence of Precision Medicine
Precision medicine's golden age was here. Programs like the Precision Medicine Initiative, which was introduced during this year's State of the Union, demonstrate the growing interest in disease prevention and treatment approaches that consider individual differences in genes, environment, and lifestyle. To further understand disease causes and patient characterization, this program will use genomes, proteomics, metabolomics, and bioinformatics. The information gathered will eventually help doctors provide their patients with the best care possible by guiding them toward the most effective treatments.
Central to our use of biosimulation technology for drug development is the concept of accounting for individual variations. The idea of individualized medicine dosage is one such example. The use of Virtual TwinTM technology is a critical step in realizing this goal. The goal is to forecast each patient's individual risk of complicated drug-drug interactions (DDIs) by comparing their real-life traits to those of their computational twin. Multiple tiers will be involved in this matching process:
- Criteria such as gender, age, height, weight, and ethnicity
- Present medication dosage and any additional drugs
- The function of transporters and metabolic enzymes
- Ratio of organ performance
When biosimulation is mixed with 3D printing to make the formulation more flexible, it could change the way medicines are given to patients.
3D Printing Pills: Technology and Process Used
Various 3D printing processes exist, and they all use somewhat different ways to transform materials into finished products. Some use a bottle of printed liquid as their starting point, while others work from powder or filament. Vat polymerization is the process of turning liquid monomers into solid polymers using light interactions. The printing process often occurs layer by layer, which can make even printing little things a time-consuming ordeal. In order to significantly shorten the time required to print pharmaceuticals, scientists employed a modified form of vat polymerization.
The term "additive manufacturing" usually describes what you're doing when 3D printing. Adding a new layer always takes longer than expected due to printer motion or other variables. Using light from three different directions, we built a mirror system. Goyanes to SYFY WIRE, the reaction co-occurs, and there are no layers.
This revolutionary technology uses three light sources to construct the complete item at once, as opposed to the traditional bottom-mounted vat polymerization printer that uses a single light source to create layers. It takes no more than seven seconds to complete the printing process.
Researchers incorporated active medicinal chemicals into the monomers while they were still liquid in order to manufacture medications. The printing process traps such chemicals within the polymers. Crucially, you may print numerous tablets simultaneously, which significantly reduces the print time required for each tablet. "We can print more than three tablets simultaneously; nevertheless, that is the current capacity. The quickest time we were able to print was seven seconds, which means that each tablet just takes a few seconds," according to Goyanes.
Keep in mind that the monomers they're using to print the medicine pills haven't been licensed for pharmaceutical usage just yet, and more study is required to rule out the possibility of any unwanted side effects. Assuming everything works out as planned, pharmacies and hospitals could soon have volumetric 3D printers on hand to quickly produce drugs as needed.
The real goal of the team, though, is to figure out how to make each patient's medication unique. Doctors of the future will be able to blend chemicals on demand to make drugs that are perfect for each patient because the procedure is almost instantaneous and produces tablets in quantities that are more appropriate for specific prescriptions. It is not out of the question to formulate a single pill that will fulfill all of a patient's prescription demands.
"Since we're merely combining resin with drugs, you can insert various drugs for varied combinations or alter the polymers for varied release," Goyanes explained.

Personalized 3D Printed Pills: A Look Into Their Future
Although technology is still in its infancy, 3D-printed medications have great promise for transforming the healthcare system. The ability to personalize therapies through 3D printing opens up new possibilities, such as drugs that dissolve at precise rates or that target particular areas. You can also adjust the size, texture, color, and form of the pills.
The future of home medical printers has the potential to revolutionise the accessibility of medications. There are legitimate safety concerns, but new software and controls could help reduce them. Envision a world where drug dosage accuracy and waste reduction are both enhanced by the ability to print pharmaceuticals on demand.
