A 3D-Bioplotter® was employed to 3D print (3DP) a humic acid-polyquaternium 10 (HA-PQ10) controlled release fixed dose combination (FDC) tablet comprising of the anti-HIV-1 drugs, efavirenz (EFV), tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC).
Chemical interactions, surface morphology and mechanical strength of the FDC were ascertained. In vitro drug release studies were conducted in biorelevant media followed by in vivo study in the large white pigs, in comparison with a market formulation, Atripla®. In vitro-in vivo correlation of results was undertaken.
EFV, TDF and FTC were successfully entrapped in the 24-layered rectangular prism-shaped 3DP FDC with a loading of ∼12.5 mg/6.3 mg/4 mg of EFV/TDF/FTC respectively per printed layer. Hydrogen bonding between the EFV/TDF/FTC and HA-PQ10 was detected which was indicative of possible drug solubility enhancement. The overall surface of the tablet exhibited a fibrilla structure and the 90° inner pattern was determined to be optimal for 3DP of the FDC. In vitro and in vivo d rug release profiles from the 3DP FDC demonstrated that intestinal-targeted and controlled drug release was achieved.
The new technology enables the printing of personalized medications out of hydrogel objects, producing complex structures which can expand, change shape and activate on a delayed schedule. By prescribing personalized medicines, doctors will be able to accurately tailor the exposure and dosage levels for individual patients.
“We now have the technology to replace standard or traditional formulations. The population is getting older so we need to think of solutions,” said Benny.
“We can now think about combining drugs together into one drug instead of ten, to adjust the kinetics of drugs and improve patient compliance in drug administration.”
The findings of a new study suggest that the accumulation of toxic beta-amyloid proteins in the brain may not be the cause of Alzheimer’s disease.
3D Printing Drugs
Posted in 3D printing, biotech/medical
3D printing drugs is driving the pharmaceutical industry towards personalized medicine. Let’s take a look at the most recent trends and developments.
“Finally, Artifical [sic] Intelligence that will make you wonder which one of you is real,” reads one of Kapur’s recent tweets, with another urging CES visitors to stop by the NEON corner to learn more about “an Artificial Intelligence being as your best friend.”
Not Bixby
One thing Samsung will say about NEON is that it is not related to the company’s AI-powered digital assistant Bixby.
The breakthrough system combines a glucose sensor, insulin pump and a smart control algorithm to allow Type 1 diabetes patients to continually regulate blood-sugar levels.
Americans today spend more on pharmaceuticals per capita than anyone else in the world, and more than one in five say they have trouble affording their prescription drugs. But they might not know about the alternative pathways to medicine. VICE’s Hamilton Morris explores the world of clandestine chemists, DIY bio hackers, and grey markets to see if a more democratized medicinal future is indeed possible.

If you drive along the main northern road through South Australia with a good set of binoculars, you may soon be able to catch a glimpse of a strange, windowless jet, one that is about to embark on its maiden flight. It’s a prototype of the next big thing in aerial combat: a self-piloted warplane designed to work together with human-piloted aircraft.
The Royal Australian Air Force (RAAF) and Boeing Australia are building this fighterlike plane for possible operational use in the mid-2020s. Trials are set to start this year, and although the RAAF won’t confirm the exact location, the quiet electromagnetic environment, size, and remoteness of the Woomera Prohibited Area make it a likely candidate. Named for ancient Aboriginal spear throwers, Woomera spans an area bigger than North Korea, making it the largest weapons-testing range on the planet.
The autonomous plane, formally called the Airpower Teaming System but often known as “Loyal Wingman,” is 11 meters (38 feet) long and clean cut, with sharp angles offset by soft curves. The look is quietly aggressive.
Using the Moon as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars.
