Definitions
- the invention relates to a method for increasing the stability during storage and / or use of light-sensitive therapeutic systems or their components, such as active ingredients or auxiliary substances, using light protection substances which absorb or reflect electromagnetic waves.
- the invention further relates to pharmaceutical forms such as therapeutic systems or components thereof, in which the stability of light-sensitive parts or components by means for preventing access stabilticiansbeeintr Stahl- term Direction of electromagnetic 'radiation or other influences such as atmospheric oxygen, is increased.
- the causes that cause the instability of a dosage form are two-fold. On the one hand, it is the instability of the medicinal and auxiliary substances themselves that ultimately results from their chemical or physico-chemical structure; on the other hand, it is the external factors such as temperature, humidity, atmospheric oxygen and light that induce or accelerate the effects of the reactions that alter their effects .
- the extent to which the factors mentioned take effect depends to a large extent on the pharmaceutical composition of the preparations.
- Physical stability impairing processes can be for example:
- 1,4-Dihydropyridine derivatives are known to be very photosensitive. 1,4-Dihydropyridines are used medically as so-called calcium channel blockers. The drug group is used to treat hypertension and coronary heart disease. Examples are Nifidipin (Adatal®), Nitrendipin (Bayotensin®), Nimodipin (Nimotop®), Felodipine (Modip®), Nicardipin (Antagonil®), Lacidipin (Motens®), Nisoldipin (Baymycard®), Nilvadipin (Escor® ), Isradipine (Lomir®), amlodipine (Norvasc®). Due to their physicochemical properties, 1,4-dihydropyridine derivatives are suitable for transdermal application.
- the type of packaging has a strong influence on the stability of the 1,4-dihydropyridine derivatives.
- the stability can be increased by adding light-absorbing or light-reflecting additives.
- yellow-colored nifidipine the influence that differently colored packs have on stability could be demonstrated.
- the best results have been achieved when tablets containing active ingredients are used a green blister pack.
- the sun protection became increasingly weaker in the order yellow, red and orange. Blue or colorless blister packs, so-called blisters, offered no protection.
- the use of substances absorbing UV-A rays also brought no improvement.
- WO 91/09731 describes a packaging material that is suitable for long-term storage of nicotine preparations.
- a laminate which serves as a barrier, is used to produce the packaging material. In this function, the laminate is intended to neutralize the influence of various external factors, such as air, water and / or light, which impair the stability of nicotine.
- TTS transdermal therapeutic system
- TTS for the administration of nicotine.
- This TTS consists of a carrier film, a film which is permeable to nicotine, a matrix containing the nicotine and an adhesive for fixing the TTS to the skin. It is characteristic that the carrier film is impermeable to air, water and light. The light and air impermeability protects the nicotine from degradation and the water impermeability prevents nicotine diffusion.
- the measures described offer general protection. Films or laminates are used, which are components of the primary packaging or the therapeutic system. It is characteristic that these measures do not offer any specific protection, but rather aim to protect the therapeutic systems in general from environmental influences. The factors air, water and light are mentioned in this context.
- the invention has for its object to provide a method for increasing the stability during storage and / or application of light-sensitive therapeutic preparations, systems or their components, such as active ingredients or auxiliary substances, using electromagnetic wave absorbing or reflecting light protection substances, in particular in the case of therapeutic Systems for applying active ingredient to or through the skin to ensure the stability of light-sensitive components by developing specific protection against degradation by harmful factors such as atmospheric oxygen, water and / or light.
- the invention proposes that to protect the therapeutic preparations, systems or their constituents, such as active substances or auxiliaries, absorption or reflection agents are used, the absorption or reflection spectrum of which comprises the wavelength range which is responsible for the instability of the photosensitive substance or its components.
- the inventive measure described ensures optimal protection because the noxious substances responsible for instability are specifically retained.
- Lacidipine is used as a representative of the very light-sensitive 1,4-dihydropyridine derivatives.
- lacidipine it can be shown what influence the absorption spectrum of a polymer used, e.g. based on polypropylene on the stability of the 1,4-dihydropyridine derivative.
- lacidipine was dissolved in a solvent. Since lacidipine in solution is very sensitive to electromagnetic radiation, the influence of the investigated polymers could be clearly determined.
- the lacidipine solution was filled into differently colored polypropylene vessels and exposed to daylight for a defined period of time. In this context, the vessels served as a model for a colored film. After a certain irradiation (over a period of 6-8 hours), the lacidipine content of the samples was determined. From the known Ang concentration and recovered amounts of active ingredient could make a statement about the protective effect of the polymers used. The results showed that the most effective light protection is guaranteed if the absorption spectrum of the polymer used comprises the wavelength range which is responsible for the instability of the lacidipine. The results are summarized in Table 1 below:
- the invention encompasses a pharmaceutical form in which the stability of light-sensitive parts or components is substantially increased by means of means for preventing the access of components which impair stability, such as air, water and / or light, in that the means materials such as glass, films, polymers etc. include, whose absorption or reflection spectrum includes the wavelength range, which is responsible for the breakdown of active substances or auxiliary substances, and which are impermeable at least for the access of air and light.
