Definitions
- the present invention relates to the field of chemistry and more particularly of pharmacotechnia.
- It more specifically relates to a degassing process, in particular deoxygenation, of liquids containing a phenolic substance and more particularly of injectable paracetamol solutes to bring their oxygen content to extremely low values, often less than 1 mg / 1.
- Heating the water to a temperature close to boiling which has the effect of reducing the solubility of dissolved gases, including oxygen.
- this technique is sometimes imperfect and difficult to use on production sites or at large ladder.
- This process also requires, in addition to the bubbling of an inert gas, to maintain the solution under vacuum, once conditioned, since the vacuum thus produced promotes the elimination of traces of oxygen still present in the solution.
- This process for stabilizing injectable aqueous solutions or suspensions of phenolic substances is characterized by the fact that it combines simultaneously and by a particular process, at least two of the degassing processes previously described, obtaining a synergistic effect, namely , heating and / or high vacuum and / or bubbling of an inert gas and / or use of ultrasound.
- the content of residual gases and in particular of oxygen in the medium can vary from 0.4 to 4 mg / 1.
- Another advantage of the process according to the invention lies in the fact that it can be applied to any volume of solution and that it finds its use in the degassing of large-volume tanks used for the bulk preparation of a large volume of solution of substances sensitive to oxidation, such as for example a phenolic substance such as paracetamol.
- Another advantage also resides in the fact that the method according to the invention can be implemented only at the end of the distribution in bottles, before capping and possible crimping of the bottles containing the solution. It is very fast and easy to apply, since the duration of exposure to ultrasound is very short. Depending on the volume of solution and the size of the container to be degassed, the power of the ultrasonic generator should be adapted and the appropriate ultrasonic transducer (sonotrode) used.
- an ultrasound generator is used operating at a frequency varying from 20 to 100 kHz, and the power can be adjusted between 0 and 130 Watts depending on the volume of the container, such as for example for small bottles.
- Sonotrodes with a diameter of the order of 1 mm to 25 mm are preferably used and for example for bottles of 100 ml, 3 mm X 45 mm or 6 mm x 60 mm delivering powers varying from 0 to 100 W and more specifically from 15 to 50 W, specifically from 15 to 25 W or from 35 to 50 W depending on the size of the sonotrodes.
- the duration of exposure to ultrasound can vary from 10 seconds to 120 seconds and preferably from 15 seconds to 60 seconds. It is preferably carried out under vacuum using a suitable vacuum pump such as a vane pump.
- the initial or residual oxygen content is measured using an oximeter operating according to the Clark principle giving the value of the oxygen content in mg / 1.
- the calibration of the scale is carried out between a zero point (reducing solution) and the oxygen saturation content of the distilled water, taking into account the temperature of the medium and atmospheric pressure.
- the oxygen content is calculated by using an abacus as a function of temperature and pressure.
- the temperature of the medium is measured using an electronic thermometer to 1/10 th of a degree.
- solutions or dispersions in particular aqueous and containing oxidizable substances are distributed in containers or in glass bottles, for example from 125 ml filled to 100 ml.
- the efficiency of the process according to the invention was determined on distilled water solutions containing no active principle sensitive to oxygen, to determine the residual oxygen concentrations obtained using the degassing technique according to the invention. 'invention.
- aqueous solution of a substance sensitive to oxidation such as a phenolic substance such as adrenaline, adrenalone, pephedrine. , epinephrine, suprenaline, adrenochrome, propaphenone, dobutamine or a hydro-aromatic substance such as for example a phenothiazine, riboflavin, tetrahydro 10-amino acridine, anthracylines, tetracylines and the like and especially aqueous solutions of paracetamol.
- a substance sensitive to oxidation such as a phenolic substance such as adrenaline, adrenalone, pephedrine. , epinephrine, suprenaline, adrenochrome, propaphenone, dobutamine or a hydro-aromatic substance such as for example a phenothiazine, riboflavin, tetrahydro 10-amino acridine, anthracy
- the quantity of oxygen eliminated by the process according to the invention is a direct function of the duration of exposure to ultrasound and the duration of the evacuation. It is also a direct function of the ultrasonic power delivered. It also depends on the temperature of the medium.
- the residual oxygen content after implementation is generally between 0.4 and 0.6 mg / 1.
- Ultrasonic generator operating at 20 KHz of power, adjustable between 0 and 130 Watts.
- Ultrasonic transducers with diameters of 3 mm x 45 mm or 6 mm x 60 mm respectively delivering powers of 15 - 25 W or 35 - 50 W.
- a 2-stage vacuum pump is also used, delivering a maximum vacuum of 3 x 1O -3 m bar.
- the oxygen content is determined using an Oximeter operating according to the Clark principle giving the value of the oxygen content in mg / L.
- the scale is calibrated between a zero point (reducing solution) and the saturated oxygen content of distilled water, taking into account the temperature and atmospheric pressure. This content is given by an abacus (oxygen content as a function of temperature and pressure).
- the device is completed by an electronic thermometer to 1/10 th of a degree. The liquid is divided into 125 ml glass bottles filled to 100 ml.
- the flasks are filled to 100 ml with distilled water in which air is bubbled until the oxygen content is balanced.
- the sonotrode is introduced into the bottle through a hole made in the elastomer stopper, as is an infusion needle intended for evacuating the bottle and connected for this purpose to the vacuum pump by a flexible tube intended to support the void without collapsing.
- the assembly is designed so as to seal the bottle relative to the outside.
- the vacuum alone is tested, the ultrasounds alone at the 2 powers delivered by two different sonotrodes and the vacuum + ultrasound association.
- the exposure times are 15 sec. , 30 sec. and 1 min
- the vacuum in the bottles is broken by coating consisting of an inert gas such as argon.
- the oximetric probe After opening the cap, the oximetric probe is introduced into the bottle and the measurement carried out.
- This coating is intended to avoid re-contamination by oxygen and guarantees an exact measurement of oxygen.
- the amount of oxygen removed is a direct function of the duration of exposure to both ultrasound and vacuum. It is also a direct function of the ultrasonic power delivered.
- the process is therefore also effective in the presence of a dissolved substance.
- Example IH Combination of the bubbling of an inert gas and ultrasound
- the flasks are filled to 100 ml with distilled water in which air has been bubbled until the oxygen content has equilibrated.
- the sonotrode is introduced into the bottle as well as the pipe fitted with the sintered device.
- the system is not sealed, so that excess argon and dissolved gases escape.
- the exposure times are 15 seconds, 30 seconds and 1 minute.
- the oximetric probe is introduced into the bottle and the measurement is carried out.
- the test procedure is identical to that of the previous test, but by varying the water temperature.
- the measurement is carried out after balancing the temperature of the water heated to 40 ° C. - 45 ° C. and 50 ° C.
- the efficiency of the process is further increased when the sonotrode is maintained in the gas stream.
- the invention finds its use in the production of pharmaceutical forms, especially of injectable solutions containing as active principle a therapeutic substance with phenolic structure such as paracetamol.
- the process according to the invention is also used for producing stable aqueous solutions or dispersions of food products which are alterable to oxygen, such as fatty emulsions, carotenoid dispersions or phospholipid solutions.
- solutions or dispersions thus obtained are distributed in bags or hermetically sealed bottles ready for use.
