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.”

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.

Whenever someone refers me to a story with alarming facts that should surprise or outrage any thinking human, my spider-sense is activated. Does the story make sense? Is it plausible? If the message contains evidence of being repeated (or forwarded to more than two friends), then whatever is claimed is almost certain to be false.

If the subject is important to me—or if there is any chance that it might influence my view of the world, I check it at Snopes. The reputable web site confirms or debunks many urban legends and all sorts of viral web hype.

You never know what you might learn at Snopes. You can easily be lured into a rabbit hole, digging into the site beyond whatever prompted your visit in the first place.

VITAMINS-Nutrients have long been described as healers-Life extending amino acids-chemicals… As has been done in the past holds true presently. There are trained professionals who for one reason or another attack the vitamin industry.

(Many claiming that vitamins do nothing and are washed from the body???)

How then did niacin extraction and synthesizing and being put into foods help end many sicknesses??? Yes Niacin is listed as a vitamin and a medicine…

So why is so much done and said against supplements??? Snake oil salesman and Big Pharma. I hate the term snake oil but it has been used against me and many others such as Doctor Aubrey de Grey…

SADLY There are those minds that have lied and harmed many down through the years by conartist-snake oil salesman… BUT For every bad product in nutrients there are 5 and more that are not so… WHAT SAY YE??? AEWR gerevivify.blogspot.com/
