[0093] The discrete units of the suspension or solution or emulsion may be in the form of liquid units or suspension units, for example contained within the pockets of a suitable mould, solid units, for example frozen units, or gelled units where the carrier material readily forms a gel.

[0094] The liquid solution or suspension which may be contained within the pockets of a suitable mould is frozen, for example by passing a gaseous cooling medium, such as Liquid Nitrogen over the mould, or by inserting the mould into a nitrogen spray freezing chamber, or cooling by passing the mould over a cold surface using Liquid Nitrogen. After the dosage forms have been frozen, the mould is loaded into the Freeze drier/Lyophiliser for Freeze drying or may be stored in a cold storage equipment before loading into the Freeze Drier/Lyophiliser, prior to drying.

[0095] The solid dosage forms are prepared by the sublimation or removal of solvent/water from a solution or suspension or emulsion comprising the pharmaceutically active substance and the carrier material. Sublimation or removal of solvent or water is carried out by freeze drying. The solvent or water is sublimed in a freeze-drying process under a reduced pressure which transforms the solid solvent directly into a vapour. The freeze-drying process will generally be carried out in a freeze-drying chamber typically operating under a vacuum of 0.1 to 1.0 mBar for a period from 100 to 800 minutes.

[0096] The process of the present invention is also intended to be applied to pharmaceutically acceptable salt form of the active ingredient or the medicament.

[0097] The other excipients are selected from the group consisting of diluents such as microcrystalline cellulose, bulking agents such as lactose monohydrate, adhesive agents such as potato starch and amylopectin, emollients, surfactant polymers such as Macrogols, colorants, sweeteners, flavouring agents, taste-masking agents or preservatives can be added to the aqueous phase of the present composition.

[0098] The process of taste masking can be carried out by any of the processes known in the art, not limiting to complexation with cyclodextrins, ion exchange resins or any other suitable agents. Taste masking can also be achieved by coating the solid pharmaceutical dosage forms with water soluble or insoluble polymers or polymers having pH dependent solubility or waxes.

[0099] The solvent used in forming the solution or suspension of pharmaceutically active substance is preferably purified water, but it may be admixed with co-solvent such as alcohol, if it desired to improve the solubility of active substance.

[0100] The specific examples of the compositions and processes thereof are described hereinafter. The following examples given by way of illustration will serve to illustrate the practice of this invention and therefore should not be construed to limit the scope of the invention.

[0147] The Manufacturing Process for Example 6:

[0148] (i) Preparing the solution of Potato starch and Amylopectin, an adhesive agent by adding in purified water and mixing thoroughly with a stirrer. Then heating the mixture to 40° C. to 50° C. for 10 to 30 minutes to allow dissolving of the polymers.

[0149] (ii) Once the solution cooled down to room temperature, adding a surfactant polymer, emulsifying agent, diluent, bulking agent, matrix-forming agent and structure-forming agent i.e. Macrogol, glycine, polysorbate 80, microcrystalline cellulose, lactose, Pullulan and mannitol individually, under stirring to obtain a homogenous solution.

[0150] (iii) Preparing a complex suspension by adding Cannabidiol, Hydroxypropyl betacyclodextrin/Beta-cyclodextrin (std.), a solubilizing agent, Sweetener and Flavouring agent to above solution to obtain a homogenous suspension

[0151] (iv)Transferring the homogenous suspension to a dosing tank and stirring/homogenizing the said suspension until the end of the filling process

[0152] (v) Forming blister pockets in blister filling machine. Use of peristaltic pump (or any pump of equivalent performance) to dose accurate amount of suspension into preformed blister pockets

[0153] (vi) Freezing the drug suspension filled blister pockets by passing through liquid nitrogen freezing tunnel temperature ranging from −160° C. to −70° C. and pressure ranging from 3 kg/cm2 to 9 kg/cm2,

[0154] (vii) The frozen product is then placed into lyophilizer. Lyophilizing the said frozen blister sheets at a primary drying temperature ranging from −30° C. to 0° C. followed by lyophilizing at a secondary drying temperature ranging from 15° C. to 20° C. under specific ranges of vacuum to obtain a rapidly disintegrating solid oral/sublingual dosage form comprising Cannabidiol.

[0155] (viii) Analyze the freeze-dried tablets for complete finished product specification (Description, identification, assay, related substance, dissolution and water content).

[0157] Manufacturing Process:

[0158] Nano Emulsion preparation:

[0159] Oil in water emulsion preparation procedure.

[0160] Polysorbate 80 and Cannabidiol oil were taken in a separate beaker and subjected to sonification using ultrasonicator. This mixture was slowly added to the Lecithin/water pre-mix placed on water bath under sonification for 10 minutes at 30%-90% amplitude or high-pressure homogenizer to form a Nanoemulsion

[0161] having droplet size of 60 Nanometer to 5 microns.

[0162] Bulk suspension preparation for rapidly disintegrating tablets process:

[0163] (i) preparing a complex suspension comprising Cannabidiol Oil in water emulsion, an oleaginous carrier, binder(s), matrix-forming agent(a) and pharmaceutically acceptable ingredients to obtain a homogenous suspension,

[0164] (ii) transferring the homogenous suspension to a dosing tank and stirring/homogenizing the said suspension until the end of the filling process

[0165] (iii) Forming blister pockets in blister filling machine. Use of peristaltic pump (or any pump of equivalent performance) to dose accurate amount of suspension into preformed blister pockets

[0166] (iv) freezing the drug suspension filled blister pockets by passing through liquid nitrogen freezing tunnel temperature ranging from −160° C. to −70° C. and pressure ranging from 3 kg/cm.sup.2 to 9 kg/cm.sup.2,

[0167] (v) placing the frozen product into lyophilizer and lyophilizing the said frozen blister sheets at a primary drying temperature ranging from −30° C. to 0° C. followed by lyophilizing at a secondary drying temperature ranging from 15° C. to 25° C. under certain ranges of vacuum to obtain a rapidly disintegrating solid oral/sublingual dosage form comprising Cannabidiol.

[0168] The freeze-dried tablets thus obtained analyzed for complete finished product specification (Description, identification, assay, related substance, dissolution and water content).

[0169] The freeze-dried tablets disintegration resulted in 5 to 15 seconds (limit NMT 30 seconds).
