Definitions
- the present invention describes complex buffer systems for increasing the stability of pharmaceutical preparations during manufacture and storage. Because of their special properties, the buffer mixtures according to the invention are particularly suitable for parenteral use. They are particularly suitable for the production of contrast medium solutions.
- buffer solutions are often used in aqueous formulations, the storage stability of which requires a certain pH. Since decomposition processes such as hydrolysis or oxidation as well as solubility differ in pH
- DE 2926850 describes a process for the production or sterilization of special, iodine-containing X-ray contrast medium solutions which is based on the temperature-dependent lowering of the pH of amine-buffered solutions.
- a significant reduction in iodide formation during manufacture could be achieved can be achieved.
- the pH value of the corresponding solutions almost returns to the original value.
- aqueous buffer systems according to the invention are mixtures of a physiologically compatible amine and a physiologically compatible aliphatic or aromatic organic acid.
- Physiologically compatible amines or acids are to be understood as those substances which have already been approved as pharmaceuticals or pharmaceutical additives or which occur under physiological conditions in the human or animal organism.
- N-methylglucamine meglumine
- Trometamol (2-amino-2- (hydroxymethyl) -1,3-propanediol, TRIS) is used, particularly preferably trometamol.
- Mono- or polyvalent carboxylic acids for example succinic acid, maleic acid, benzoic acid
- hydroxycarboxylic acids for example glycolic acid, citric acid, malic acid or lactic acid
- keto acids for example ⁇ -ketoglutaric acid
- sulfonic acids for example 2- [ 4- (2-hydroxyethyl) -1-piperazino] ethanesulfonic acid (HEPES)
- amino acids eg glycine, aspartic acid, phenylalanine, lysine, arginine, preferably the naturally occurring L-amino acids
- succinic acid is combined with trometamol.
- Components can be mixed in any molar ratio.
- 1: 1 e.g. 10 mM Tris and 10 mM glycine
- other mixing ratios between 1:99 and 99: 1 can also be set. In some cases very good results are achieved with mixing ratios of 25:75 and 75:25.
- salts of the main buffer components in addition to the substances customary to the person skilled in the art, such as, for example, sodium hydroxide solution or hydrochloric acid, salts of the main buffer components, for example, can also be used.
- the buffers according to the invention offer, in particularly suitable cases, the possibility of an optimized adaptation of the pH to the stability requirements of the respective pharmaceutical substance, taking into account physiological requirements.
- buffer systems according to the invention can, if necessary, also be used effectively below this pH range.
- the buffers according to the invention also prove to be superior to conventional buffer systems in the range of the isohydric pH (approx. 7.4).
- buffer mixtures according to the invention when using buffer mixtures according to the invention, the addition of further formulation auxiliaries such as, for example, complexing agents (for example sodium calcium edetate) can be dispensed with, since the buffer mixtures according to the invention themselves have a complexing effect in particularly suitable cases.
- the formulations according to the invention do not favor a microbial Infect precipitation reactions with ions from the primary container.
- the formulations according to the invention are furthermore notable for particularly good tolerability.
- Parenteral preparations according to the invention are generally adjusted to pH values between 4 and 9 or 5 and 8. In special cases, however, pH values between 6.0 and 8.0 or 5.0 and 6.7 are aimed for.
- the buffer mixtures according to the invention show a marked temperature dependence with regard to their pH. Surprisingly, it could be shown that the steepness of the temperature-dependent drop in the pH value of buffers according to the invention is clearly dependent on the starting pH.
- the pH of formulations according to the invention drops during the heat sterilization (121 ° C., 20 min) by more than 0.5 or 1 to 3 pH units.
- the extent of the pH depression and thus any decomposition reactions that may occur during the sterilization can be controlled by targeted selection of a buffer system according to the invention for a special pharmaceutical substance. In certain cases, a lower pH drop during sterilization may be desirable with a view to avoiding special decomposition processes.
- the osmolality is generally set to values in the range from 200 to 1200 mOsm / kg or 200 to 1000 mOsm / kg or in particularly preferred cases between 250 and 850 mOsm / kg.
- the buffer systems according to the invention are characterized in that usually low total concentrations in the range from 2 to 40 mM, but preferably between 10 and 20 mM or 5 and 15 mM can be used.
- the buffer systems according to the invention are particularly suitable for stabilizing contrast media, in particular X-ray contrast media based on iodine-containing aromatics. On the one hand, stabilization during production comes into play, which is only partly due to the pH drop during the sterilization process.
- trometamol buffer pH 7.5
- a significant reduction in iodide formation with a single and repeated sterilization 121 ° C., 20 min
- iopromide Detect solutions 300 mg iodine / ml
- the buffer according to the invention shows only a comparatively small temperature-dependent pH decrease at this starting pH compared to trometamol / HCl buffer.
- Similar results were obtained when using a trometamol / succinic acid buffer or trometamol / HEPES buffer (pH 7.5).
- Buffer capacity also allow the buffer systems of the invention potentially further stabilization during manufacture. For example, adjusting the pH of an iopromide solution (300 mg iodine / ml) in the trometamol / succinic acid buffer according to the invention to pH 6.5 resulted in a further drastic reduction in iodide formation during sterilization (20 min, 121 ° C.) compared to one comparable trometamol buffered solution. This effect was also pronounced with longer sterilization times, so that buffer systems according to the invention also enable repeated sterilization of X-ray contrast medium solutions in particularly suitable cases.
- buffer systems according to the invention over the buffers used hitherto lies in the additional increase in the stability of X-ray contrast media solutions during storage.
- buffers according to the invention it is generally possible to achieve maturities of over 3 years, but preferably 4 to 6 years or 5 to 10 years, as a result of reduced decomposition reactions.
- the iodide content and, in special cases, the free amine content are used as a particular measure of the stability of corresponding solutions.
- the iodide content of X-ray contrast media solutions are used as a particular measure of the stability of corresponding solutions.
- buffers according to the invention can also be used to reduce the amine formation during storage in particularly suitable cases.
- the content of corresponding solutions (e.g. 300 mg iodine / ml) of free amine is usually during the term below 0.3%, but preferably below 0.1 or 0.05%.
- the buffers according to the invention are particularly suitable for the stabilization of parenterally applied hydrophilic
- X-ray contrast media which are generally known from radiological practice.
- these include the X-ray contrast media such as amidotrizoate, metrizoate, iopromide, N, N'-bis (2,3-dihydroxypropyl) -5-hydroxyacetylamino-2,4,6-triiodo-N-methylisophthalamide,
- CT computer tomography
- the X-ray contrast media can also be encapsulated in liposomes.
- the buffer systems according to the invention can, in special cases, regardless of the mode of application (for example parenterally, orally, topically (also ophthalmic drugs)) also for stabilizing other aqueous drug solutions or suspensions (for example crystal suspensions, liposomes, micro or nanoparticles or - capsules) can be used.
- MRI contrast agents such as Gd-DTPA, Gd-EOB-DTPA, Gd-DOTA, Gd-BOPTA, Mn-DPDP, gadobutrol or ultrasound contrast agents
- therapeutic agents such as analgesics / anti-inflammatory drugs, antibiotics are, as non-limiting examples To name cytostatics and antivirals.
- These groups of active ingredients can also be present as liposomal formulations. Examples:
- Example 1 Stability of a trometamol / HCl buffered iopromide solution
- a trometamol (20 mM) buffered iopromide solution (adjusted to approximately pH 7.5 or 6.5 with HCl) with an iodine concentration of 300 mg / ml was prepared and aliquots of this solution in sealed 10 ml injection bottles for the period given in the table autoclaved (121 ° C). The samples thus obtained were examined for their pH, iodide and amine content (free aromatic amine).
- Example 7 Temperature dependence of the pH value of a trometamol buffered solution
- a 20 mM trometamol solution is adjusted to pH 7.5 with 0.1 N HCl and the pH is determined as a function of the temperature using a Knick 761 pH meter with and without temperature correction or compensation. The results are shown in Figure 1.
- aqueous buffer solutions (each 10 mM based on each buffer component) are prepared and the pH is determined as a function of the temperature using a 761 pH meter from Knick.
- the respective temperature of the buffer solutions was measured with an external Pt-100 sensor and the temperature on the pH meter was corrected accordingly. The data thus obtained are shown in FIGS. 2 and 3.
- Example 9 Three-month stability of an iopromide solution as a function of different buffers
- Buffered lopromide solutions 300 mg iodine / ml prepared analogously to Examples 1 and 2 were first autoclaved in 10 ml injection bottles (20 min, 121 ° C.) and then stored in a climatic cabinet at 40 ° C. for three months. Solutions were stored in parallel which had been adjusted to an initial pH value (before sterilization) of 7.5 or 6.5. The samples thus obtained were examined for their iodide, amine (free aromatic amine) and sodium calcium edetate content.
- Placebo liposome solutions consisting of
- Soybean phosphatidylcholine (150 mg / ml) was produced using continuous high-pressure extrusion (5 passages each)
