Abstract

Pharmaceutical compositions with tryptamines having enhanced active stability properties are described.

Claims (41)

1. A method comprising orally administering to a subject an oral dissolvable film comprising:

(i) a flowable water-soluble or water-swellable film-forming matrix that includes at least one polymer,

(ii) psilocybin, psilocin, baeocystin, or a combination thereof; and

(iii) a stabilizing inorganic acid;

wherein, the psilocybin, psilocin, baeocystin, or combination thereof is present in a combined amount of 1 to 30 mg,

wherein the ratio between psilocybin and psilocin to the inorganic acid is 1:0.5 to 1:2 w/w and wherein the surface pH of the film is between 2 and 4.5.

2. The method of claim 1 wherein the inorganic acid is phosphoric acid.

3. The method of claim 1 , wherein the administering is for improving creativity, boosting physical energy level, attaining emotional balance, increasing performance on problem-solving tasks, treating anxiety, treating depression, treating addiction, or any combination thereof.

4. The method of claim 1 , wherein the administering is for treating at least one of obsessive compulsive disorder (OCD), pain, irritability, fibromyalgia, post-traumatic stress disorder (PTSD), cluster headaches, paranoia, psychosis, anxiety, panic attacks, flashbacks, smoking addiction, alcohol addiction, and cocaine addiction.

5. The method of claim 1 , wherein 1-5 oral dissolvable films are orally administered per day.

6. The method of claim 1 , wherein the psilocybin, psilocin, baeocystin or combination thereof is delivered enterally, sublingually, or transmucosally.

7. The method of claim 1 , wherein the oral dissolvable film comprises the psilocybin, psilocin, baeocystin, or combination thereof in a combined amount of 5 to 25 mg.

8. The method of claim 1 , wherein the oral dissolvable film comprises the psilocybin, psilocin, baeocystin, or combination thereof in a combined amount of 10 to 20 mg.

9. The method of claim 1 , wherein the flowable water-soluble or water swellable film-forming matrix that includes a polymer comprises each of plasticizer, binder, preservative, and solvent.

10. The method of claim 1 , wherein the flowable water-soluble or water swellable film-forming matrix comprises less than 5 ppm of stabilizers that are not inorganic acids.

11. The method of claim 1 , wherein the oral dissolvable film comprises less than 5 ppm of any of the following EDTA, BHT, propyl gallate, vitamin E or copper, sodium sulphite, sodium bisulphite, sodium thiosulphate, sodium formaldehyde sulfoxylate, sulphur dioxide, ascorbic acid, gallic acid, propyl gallate, isoascorbic acid, thioglycerol, thioglycolic acid, cysteine hydrochloride, acetylcysteine, butylated hydroxy toluene, butylated hydroxy anisole, alpha tocopherols, lecithin, ascorbyl palmitate or nordihydroguaiaretic acid or any derivative or combination thereof.

12. An oral dissolvable film comprising:

(a) plasticizer,

(b) solvent,

(c) sweetener,

(d) flavoring agent,

(e) binder,

(t) inorganic acid,

(g) preservative, and

(h) psilocybin, psilocin, or combination thereof,

wherein the ratio of inorganic acid to psilocin and psilocybin is 1:0.5 to 1:2 w/w

wherein the surface pH of the film is between 2 and 4.5.

13. The oral dissolvable film of claim 12 , wherein the inorganic acid is phosphoric acid.

14. An oral dissolvable film comprising:

(a) plasticizer selected from the group consisting of glycerol, glycerol monoacetate, diacetate or triacetate, triacetin, polysorbate, cetyl alcohol, propylene glycol, sorbitol, sodium diethylsulfosuccinate, triethyl citrate, and tributyl citrate,

(b) solvent selected from the group consisting of water, ethanol, and combinations thereof,

(c) sweetener,

(d) flavoring agent,

(e) binder selected from the group consisting of pectin, pullulan, starch, pregelatinized starch, gelatin, polyvinylpyrrolidone, methylcellulose, sodium carboxymethylcellulose, ethylcellulose, polyacrylamides, polyvinyloxoazolidone, and polyvinylalcohols,

(f) acidifying agent selected from the group consisting of inorganic acids,

(g) psilocybin, psilocin, or combination thereof,

wherein the ratio between psilocybin and psilocin to the inorganic acid is 1:0.5 to 1:2 w/w, and wherein the surface pH of the film is between 2 and 4.5.

15. The oral dissolvable film of claim 14 , which comprises less than 5 ppm of any of the following: EDTA, BHT, propyl gallate, vitamin E or copper, sodium sulphite, sodium bisulphite, sodium thiosulphate, sodium formaldehyde sulfoxylate, sulphur dioxide, ascorbic acid, gallic acid, propyl gallate, isoascorbic acid, thioglycerol, thioglycolic acid, cysteine hydrochloride, acetylcysteine, butylated hydroxy toluene, butylated hydroxy anisole, alpha tocopherols, lecithin, ascorbyl palmitate or nordihydroguaiaretic acid or any derivative or combination thereof.

16. The oral dissolvable film of claim 12 , wherein the psilocybin, psilocin, or combination thereof, is in a combined amount of 5 to 25 mg.

17. The oral dissolvable film of claim 12 , wherein the psilocybin, psilocin, or combination thereof, is suspended in an amorphous form within the oral dissolvable film.

18. The oral dissolvable film of claim 12 , further comprising a barrier layer comprising at least one water-insoluble polymer.
