Definitions
- An effervescent formulation comprising pyridoxal-5-phosphate, its method of preparation and its use in the treatment of neonatal epilepsy.
- Pyridoxal 5 phosphate should be given to all neonates with epileptic seizures who have not responded to first-line therapy.
- vitamin-sensitive epilepsy should be considered. There are two major entities: pyridoxonide-dependent epilepsy (OMIM 266100) and pyridoxamine-5-phosphate oxidase deficiency (OMIM 610090). In both diseases, early administration of pyridoxal phosphate can control epileptic seizures. The recommendations are therefore to treat all newborns and young infants who have epileptic seizures that do not respond to first-line treatment. In case of diagnostic confirmation, the treatment is administered for life.
- Pyridoxal 5 phosphate or pyridoxal phosphate is an essential vitamin in the management of neonatal epileptic seizures and will be maintained for life in patients diagnosed with vitamin-sensitive epilepsy. will be confirmed.
- P5P is currently provided to some neonatal services in the form of preparations made according to local habits, usually containing microcrystalline cellulose. Their administration to neonates is difficult because P5P is poorly soluble in water, a phenomenon characterized by the yellowish solid residue observed on the dissolution device. The clinical consequence is the incomplete administration of the dose as well as a loss of nursing time.
- composition may be in the form of a capsule to be opened
- a pharmaceutical composition comprising:
- P5P pyridoxal-5-phosphate
- NaHCO 3 salt of sodium bicarbonate
- At least one pharmaceutically acceptable excipient at least one pharmaceutically acceptable excipient.
- the molar ratio of P5P / aHC0 3 is between 0.75 and 1.5; more particularly between 0.78 and 1.5; between 0.80 and 1.5; between 0.85 and 1.5 or between 0.90 and 1.5.
- the molar ratio of P5P NaHCO 3 is between 0.78 and 1.4; between 0.80 and 1.3; between 0.85 and 1, 2; or between 0.90 and 1, 1.
- said mixture M further comprises pyridoxine hydrochloride, the weight ratio of P5P / pyridoxine hydrochloride being in particular between 0.5 and 1.5.
- the excipient may be selected from a diluent, a sweetening agent, a flow agent or a mixture thereof. The excipient is especially chosen from pharmaceutically acceptable excipients in pediatrics.
- a diluting agent there may be mentioned in particular isomalt, sucrose, mannitol, sorbitol, lactose, preferably isomalt.
- the sweetening agent may especially be sucralose, sucrose, mannitol.
- colloidal silica or magnesium stearate preferably colloidal silica.
- the excipient is chosen from isomalt, sucralose, colloidal silica or a mixture thereof.
- the mixture M represents 10 to 65% by weight relative to the total weight of the composition.
- the pharmaceutical composition comprises:
- sucralose 0 to 0.3% by weight
- colloidal silica 0 to 2% by weight of colloidal silica
- the pharmaceutical composition comprises:
- sucralose 0 to 0.3% by weight
- colloidal silica 0 to 2% by weight of colloidal silica
- the pharmaceutical composition according to the invention is especially presented in the form of a pharmaceutical form intended for the oral route, in particular in the form of a capsule, to be opened or swallowed, the contents of which solubilize in water by an effervescence.
- the invention relates to a pharmaceutical composition for its use in the treatment of neonatal epilepsy as well as metabolic diseases with a need for vitamin B6 derivatives, in particular pyridoxal-5-phosphate such as hypophosphatasia , Familial hyperphosphatasia including Mabry syndrome related to phosphatidylinositol glycan anchor biosynthetase deficiency or hyperprolinaemia type 2 related to 1-pyrroline-5-carboxylate dehydrogenase deficiency [4].
- pyridoxal-5-phosphate such as hypophosphatasia
- Familial hyperphosphatasia including Mabry syndrome related to phosphatidylinositol glycan anchor biosynthetase deficiency or hyperprolinaemia type 2 related to 1-pyrroline-5-carboxylate dehydrogenase deficiency [4].
- the term "pharmaceutically acceptable” refers to excipients which are, within the scope of sound medical judgment, suitable for contact with human and animal tissues without undue toxicity. , irritation, allergic response, or other problematic complications in proportion to a reasonable benefit / risk ratio.
- FIG. 1 Laser diffraction granulometry performed on the active ingredient at
- FIG. 1 Appearance and Form of Particles - A: P5P alone, B: sodium bicarbonate and C: premix P5P / sodium bicarbonate
- FIG. 3 Graph showing the average time of dilution of the hard capsules of P5P according to the formulation of the invention ( ⁇ 1 min) (formulation A) and according to the formulation of the prior art (formulation B),
- Figure 4 Graphs showing mean values and standard deviations for capsules containing 25mg of P5P (Figure 4A) and 50mg of P5P ( Figure 4B), respectively, at different post-manufacturing analysis times. Examples
- the powder therefore has two distinct modes with a majority of fine particles smaller than 10 ⁇ m.
- the morphology was determined with an Olympus® SZCTV binocular loupe (x40 magnification) connected to a Videomet® image analysis software. This analysis was performed on the active ingredient (lot A), sodium bicarbonate (lot B) and on the premix (lot F).
- P5P The morphological analysis of P5P shows a fluffy powder of small size, presenting clusters (Lot A). Sodium bicarbonate shows a small crystalline powder (Lot B).
- the premix 100 mg of P5P / 34 mg of sodium bicarbonate - Lot C) takes up this fluffy appearance, showing aggregates as shown previously for lot A and consists of two distinct populations. P5P powder and premixture appear highly electrostatic. To limit this phenomenon, colloidal silica could be added to the mixtures.
- the mixing time can be set to 5 minutes.
- Formulation A was prepared as follows:
- the P5P and then the colloidal silica were then incorporated into a suitably sized mortar and mixed. Then, Na bicarbonate was incorporated, and then all was mixed.
- the powder mixture obtained was then packaged in the hard capsules.
- Formulation B was prepared as follows:
- the powder mixture obtained was then packaged in the hard capsules.
- the stopwatch was stopped at 180 seconds if the dilution was not complete.
- the experiment was carried out on 5 hard capsules of each formulation (IOmg of P5P in 2 ml of water).
- Example 5 Stability study over time of pyridoxal-5-phosphate content of effervescent formulations containing pyridoxal-5-phosphate (P5P)
- This formulation is prepared as follows:
- P5P and pyridoxine hydrochloride then the colloidal silica, are then incorporated in a mortar of suitable size, and mixed. Then, Na bicarbonate is incorporated, then the whole is mixed.
- the powder mixture obtained is then packaged in the hard capsules.
