1/ ImageImageImage
Application claims compositions of “psilocybe-derived agent and a cannabis-derived agent”

”formulated in multiple layers to release the psilocybin-derived agent and the cannabis-derived agent at multiple different times, dosages and/or locations in a subject during dosing”

2/ Image
Application asserts controlled release formulations of psilocybin + CBD can result in “multiple chemical-induced high/low shocks”

"useful in eliciting short or long term traumatic experience suppression in similar fashion to electroshock therapy without memory eradication”

3/ ImageImage
Preliminary written opinion found psilocybe & cannabis derived compounds not disclosed before “in a tablet formulated in alternating layers,” & thus novel

However, “skilled person would not require inventive ingenuity to use the layered formulation”

4/ ImageImageImageImage
Preliminary written opinion cited two earlier-filed applications to combinations of psilocybe & cannabis compounds

These were filed by Paul Stamets & CaaMTech

Application by CaaMTech—soon to issue—was “considered to represent the closest prior art”

Deuterated DMT analogs?

New patent application by Small Pharma published today.

The “invention provides compositions and methods which enable a finely tuned single dose to maintain a patient in full dissociation from the external world, referred to herein as ‘DMT space.’”

1/ Image
In particular, the invention takes advantage of “the kinetic isotope effect” exhibited by deuterated DMT analogs “in order to modify, controllably, the pharmacokinetic profile of N,N-DMT, thereby permitting more flexible therapeutic application.”

pdfaiw.uspto.gov/.aiw?PageNum=0…

2/ Image
“Deuterated” means that one or more hydrogen atoms in DMT are replaced by its heavier stable isotope deuterium. Because of the “kinetic isotope effect,” deuterated drugs may have significantly lower rates of metabolism and a longer half-life.
