Described herein are abuse deterrent controlled release oral pharmaceutical compositions comprising and methods for making the same. In particular, an abuse deterrent controlled release oral pharmaceutical composition comprising a soft capsule and an abuse deterrent controlled release matrix comprising an active pharmaceutical ingredient are described.
Increased attention has been drawn to the recreational use and abuse of prescription pharmaceutical compositions. The abuse, or non-medicinal use, of prescription pharmaceutical compositions is an increasing problem. Accordingly, preventing the abuse of prescription pharmaceuticals through the development of abuse deterrent pharmaceutical compositions has become a high public health priority for the U.S. Food and Drug Administration (FDA). Prescription pharmaceutical compositions that are typically misused or abused fall, primarily, into three groups: (1) opioids prescribed for pain; (2) Central Nervous System (CNS) depressants prescribed for anxiety or sleep problems; and (3) stimulants, prescribed, for example, for attention deficit hyperactivity, narcolepsy, or obesity.
Methods for abusing prescription pharmaceutical compositions are varied and can include, for example, extraction, melting, volatilization, physical tampering (e.g., grinding, grating, crushing, etc.), or direct administration. For purposes of abuse, methods of administering active drug substances obtained from prescription pharmaceutical compositions or of the pharmaceutical compositions themselves are similarly diverse and include, for example, injection, smoking, snorting, swallowing, sublingual or buccal administration, chewing, or administration as an anal or vaginal suppository. Alcohol-induced “dose dumping,” i.e., the rapid release of active pharmaceutical ingredients in the presence of a solvent such as ethanol, is also an abuse concern and safety issue.
There are a number of strategies for preventing the abuse of pharmaceuticals. Physical and chemical barriers can prevent the extraction of the drug or change the form of the drug making it less likely to be abused. Combinations of agonists and antagonists can be used, wherein the antagonist is only released upon product manipulation or tampering. Another strategy is to use aversives, compounds that produce an unpleasant effect when the dosage form is tampered with. In addition, prodrugs can be used, which are only changed into the active form of the drug in the gastrointestinal tract. The pharmaceutical industry is utilizing these strategies to develop abuse-deterrent pharmaceutical compositions in order to reduce the potential for misuse of prescription pharmaceutical compositions.
Accordingly, there is a need for abuse deterrent pharmaceutical compositions that have controlled release properties. The matrix formulations described herein minimize the likelihood of tampering, “dose dumping,” or the extraction of active pharmaceutical ingredients from the composition.

A structured internal phase therefore provides controlled drug release and stabilizes the physical state of the matrix. Without being bound to any theory, it is believed that the structured nature of the matrix impedes solvation and/or diffusion of the active pharmaceutical ingredient out of the matrix.
In another embodiment, the active pharmaceutical ingredient can be dispersed in the internal phase as a suspension form. In another embodiment, the active pharmaceutical ingredient can be dispersed in the internal phase as a solid form.

Without being bound to any theory, it is believed that the hydrophilic cationic and anionic polymers described herein combine within the matrix to form polymer networks or complexes comprising ionic interactions. Further, without being bound to any theory, it is believed that the ionic polymer network swells when hydrated with an aqueous solution and the swelling impedes the dissolution and/or diffusion of the active pharmaceutical ingredient out of the matrix. Without being bound by any theory, it is believed that non-ionic surfactants and hygroscopic polymers facilitate hydration of the hydrophilic ionic polymers described herein. Moreover, without being bound to any theory, the lipid or lipophilic vehicle of the matrix further prevents diffusion and/or solvation of the active pharmaceutical ingredient. Without being bound to any theory, it is believed that the suspension agents prevent precipitation of the active pharmaceutical ingredient or other matrix components. The matrix compositions described herein permit abuse deterrence by preventing liberation of the active ingredient for injection or insufflation and prevent solvation, dissolution, or extraction of the active pharmaceutical ingredient by use of aqueous or organic solutions. Furthermore, the matrix compositions also provide controlled release delivery of the active pharmaceutical ingredient after ingestion by a subject.

Enteric soft capsules are described in International Patent Application Publication No. WO 2004/030658; U.S. Patent Application Publication No. US 2006/0165778; and U.S. Pat. No. 8,685,445, each of which is incorporated by reference herein for such teachings. The enteric soft capsule shell may comprise one or more film forming polymers, one or more enteric acid-insoluble polymers, one or more plasticizers, one or more alkali-neutralizing agents, one or more solvents, optionally one or more colorants, and optionally one or more flavorings or other conventionally accepted pharmaceutical excipients or additives.
Film-former polymers that are useful for creating enteric soft capsules are gelatin or hydroxypropylmethylcellulose (HPMC). In one aspect of the enteric soft capsule shell described herein, the film-forming polymer is gelatin.
Examples of enteric, acid-insoluble polymers are acrylic and methacrylate acid copolymers, cellulose acetate phthalate (CAP), cellulose acetate butyrate, hydroxypropylmethylcellulose phthalate (HPMCP), algenic acid salts such as sodium or potassium alginate, or shellac. Poly(methacylic acid-co-methyl methacrylate) anionic copolymers based on methacrylic acid and methyl methacrylate are particularly stable and are preferred in some embodiments. Poly(meth)acrylates (methacrylic acid copolymer), available under the trade name EUDRAGIT® (Evonik Industries AG, Essen, Germany), are provided as powder or aqueous dispersions. In one aspect, the methacrylic acid copolymer can be EUDRAGIT® L 30 D-55; EUDRAGIT® L 100-55; EUDRAGIT® L 100; EUDRAGIT® L 12.5; EUDRAGIT® S 100; EUDRAGIT® S 12.5; EUDRAGIT® FS 30 D; EUDRAGIT® E 100; EUDRAGIT® E 12.5; EUDRAGIT® E PO; EUDRAGIT® RL 100; EUDRAGIT® RL PO; EUDRAGIT® RL 30 D; EUDRAGIT® RL 12.5; EUDRAGIT® RS 100; EUDRAGIT® RS PO; EUDRAGIT® RS 30 D; EUDRAGIT® RS 12.5; EUDRAGIT® NE 30 D; EUDRAGIT® NE 40 D; EUDRAGIT® NM 30 D; or other poly(meth)acrylate polymers.

Acid-insoluble polymer specifications are detailed in the United States Pharmacopoeia and in various monographs.
Plasticizers that are useful for creating enteric soft capsules as described herein are glycerol, sorbitol, polyethylene glycol, citric acid, citric acid esters, such as tri-ethyl citrate, or combinations thereof. The weight ratio between the film-forming polymer, the enteric acid-insoluble polymer, and plasticizer is adjusted so that the gel mass is flowable and not too viscous, and can be made into soft capsules using rotary die encapsulation methods.
In one embodiment, enteric soft capsule shell compositions can be made by dissolving the enteric acid-insoluble polymer in an aqueous solution of an alkali neutralizing agent such as ammonia, sodium hydroxide, potassium hydroxide, or liquid amines such as tri-ethanol amine or ethylene diamine. The amount of alkali is adjusted to give a final pH value of the gel mass less than or equal to about pH 9.0. In one embodiment, the final pH does not exceed 8.5. The volatile alkali neutralizing agent, ammonia is preferred. The film-forming polymer can then be combined with the plasticizer and solvent and then blended with the acid-insoluble gel to make a final homogeneous mix in a heat-controlled vessel and can be degassed by using vacuum. The fugitive ammonia evaporates during degassing. Using the foregoing process, the alkali concentrations do not require an additional step such as heating or neutralizing with acid in order to neutralize the gel mass.
In another embodiment described herein, an enteric soft capsule shell can be made by using an aqueous dispersion of the acid-insoluble polymer by adding alkaline materials such as ammonium, sodium, or potassium hydroxides, other alkalis, or a combination thereof that will cause the enteric acid-insoluble polymer to dissolve. The plasticizer-wetted, film-forming polymer can then be mixed with the solution of the acid-insoluble polymer. In one embodiment, enteric acid-insoluble polymers in the form of salts of the above-mentioned bases or alkalis can be dissolved directly in water and mixed with the plasticizer-wetted, film-forming polymer.
In one embodiment, an enteric soft capsule shell has the composition of Table 4, including all possible iterations of the specified ranges that provide 100% for the total weight percentage, including or excluding the optional, excipients, opacifiers, colorants, and flavorings.
