Definitions
- the present invention relates to a process for the preparation of crystalline (6RS) -N (5) -formyl-5,6,7,8-tetrahydrofolic acid or amorphous (6S) -N (5) -formyl-5,6,7,8 tetrahydrofolic acid.
- the present invention also relates to crystalline (6RS) -N (5) -formyl-5,6,7,8-tetrahydroacid and amorphous (6S) -N (5) -formyl-5,6,7,8-tetrahydrofolic acid as such.
- the present invention also relates to a method for producing a concentrated, stable solution, in particular an injection solution or infusion solution, of the sodium or potassium salt of (6RS) - o- (6S) -folinic acid and this solution as such.
- N (5) -formyl-5,6,7,8-tetrahydrofolic acid is also called folinic acid.
- Crystalline folinic acid has not been described until the filing date of the present invention.
- Example 1 of WO 93/17022 describes the preparation of pure (6RS) -folinic acid.
- a "precipitate" of (6RS) -folinic acid is mentioned. It can be seen from the powder X-ray diagram of the product obtained according to this example shown in FIG. 2 that this product contains at least 30% of amorphous (6RS) -folinic acid.
- folinic acid would be obtained by direct acidification of an aqueous solution of a water-soluble folinate salt.
- Example 6 of EP 0 293 029 an aqueous solution of calcium (6S) -folinate is carefully mixed with dilute hydrochloric acid, the (6S) -folinic acid precipitating and being recovered by filtration.
- amorphous (6S) -folinic acid has a stability comparable to that of crystalline (6RS) -folinic acid.
- the process according to the invention for the preparation of crystalline (6RS) -N (5) -formyl-5,6,7,8-tetrahydrofolic acid or amorphous (6S) -N (5) -formyl-5,6,7 8-tetrahydrofolic acid is characterized in that to stirred water, which has a temperature of 2 ° C to 12 ° C, simultaneously an aqueous solution having a temperature of 40 ° C to 50 ° C, of (6RS) - or (6S) -calcium-folinate, and
- the process according to the invention for producing a concentrated, stable solution, in particular an injection solution or infusion solution, of the sodium or potassium salt of (6RS) - or (6S) -folinic acid is characterized in that crystalline (6RS) -folinic acid or amorphous (6S) -folinic acid in water degassed and acceptable for the preparation of injection solutions or infusion solutions, suspended at room temperature under an inert gas atmosphere, then adding an aqueous solution of sodium or potassium hydroxide, bicarbonate or carbonate portionwise until a clear solution has been obtained, which has the particular desired pH, the resulting solution of a sterile Filtration, and filling the resulting sterile solution under a nertgasatmospreheat in vials or in ampoules.
- the concentrated, stable solution according to the invention in particular an injection solution or infusion solution, is characterized in that it contains either (6S) -sodium-folinate or (6S) -calium-folinate in addition to water.
- FIG. 1 shows a powder X-ray diagram of crystalline (6RS) -folinic acid according to the invention. From Figure 1 it can be seen that the compound (6RS) -folinic acid is highly crystalline.
- Solution A This clear solution (hereinafter referred to as Solution A) was cooled to a temperature of 50 ° C.
- the relative rate of addition of the 18% aqueous hydrochloric acid was chosen so that the pH in the resulting mixture remained between 2.8 and 3.2.
- the suspension obtained was further stirred for 1 hour at a temperature of 6 ° C. and 10 ° C.
- the resulting crystalline solid was isolated by centrifugation.
- the washed, crystalline solid was dried under reduced pressure (20 to 30 mbar) at room temperature for 2 hours and at a temperature of 50 ° C for 1 hour.
- Solution B This clear solution (hereinafter referred to as Solution B) was cooled to a temperature of 45 ° C.
- 4 liters of deionized water were added and cooled with stirring to a temperature of 6 ° C.
- To said 6 ° C cold water were simultaneously added with stirring said solution B and 18% aqueous hydrochloric acid by means of two peristaltic pumps.
- the relative rate of addition of the 18% aqueous hydrochloric acid was chosen so that the pH in the resulting mixture remained between 2.8 and 3.2.
- the suspension obtained was further stirred for 1 hour at a temperature of 6 ° C and 10 ° C.
- the resulting amorphous solid was isolated by centrifugation.
- the solid was washed once with deionized water and once with a 94: 6 (v / v) mixture of ethanol and deionized water. Both washings had a temperature of 5 ° C to 10 ° C.
- the washed, amorphous solid was dried under reduced pressure (20 to 30 mbar) at room temperature for 2 hours.
- the diastereomeric purity was 99.7%
- amorphous (6S) -folinic acid prepared according to Example 2 were suspended in 1.2 liters of degassed, sterile water under a nitrogen atmosphere at room temperature.
- a 10% aqueous sodium hydroxide solution was added dropwise with stirring, until a clear solution was obtained, which had a pH of 8.0.
- the resulting clear solution was diluted to a volume of 1.8 liters by adding degassed, sterile water.
