- Figure 1 represents the plasma profile of methadone after repeated administration in vivo, in humans, of 60 mg of methadone hydrochloride in syrup form (reference) and in capsule form (test formula) in 26 patients.
- the following examples illustrate the present application. They were made with narcotics for which the technique of the invention is most interesting, but other active ingredients could have been implemented.
- a powder having the following weight composition was produced:
- One capsule contains 100 mg of the above mixture.
- Example 3 Essay of Injection of Active Ingredients Extracted from a Composition of Example 2
- the difficulty of injecting the drug after its dissolution is based on tests of gel stability, viscosity and passage through syringe needles with measurement of the force applied to the piston.
- the difficulty of injection of the developed formula was verified by using a procedure adapted to the known practices of the illicit drug users to put in solution the contents of the capsules, then:
- the difficulty of gel aspiration was investigated using tuberculin syringes, mounted syringes and a large diameter needle (19 Gauges) mounted on a 10 mL syringe noting the appearance of the gel and measuring the suction time.
- equipment usually used by intravenous drug users water, lemon, saliva, lighter, syringes, needles, spoons, sterile kits provided for this purpose and usually used by drug users
- complete dissolution in the form of a fluid gel passing through a needle of the largest internal diameter can be obtained with a significant amount of water (greater than 6 mL per 1 capsule) and special conditions (breaking the gel after some aspirations, expose to heat, inject quickly).
- the fluid gel obtained according to this protocol passes into a needle of small internal diameter (tuberculin needle, insulin) but requires a syringe body of 10 mL and a very progressive push of the piston to prevent separation of the needle from the body. syringe.
- Example 4 Bioavailability of the active ingredient extracted from a composition of Example 2
- compositions that is the subject of the patent allows the release of all of the active ingredient in a representative medium of the gastric liquid (0.1 mol / L hydrochloric acid) in a time of less than 30 minutes.
- a solid pharmaceutical composition for the oral route prepared according to the invention can not be injected by rapid solubilization ( ⁇ 2 min) in a small volume of water (1 m L) and yet does not decrease the bioavailability of the active ingredient.
- the powder contained in the capsule of Example 2 is taken. It is placed at ambient temperature in a hemolysis tube of a volume of 5 ml with 3 ml of water and shaken by manual inversion of the flask at a rate of 50 flips at 180 ° of the bottle, per minute.
