Definitions

  • the invention relates to a pharmaceutical composition for nasal use, consisting of at least one water-insoluble or sparingly water-soluble active ingredient and neutral oil, it being possible to dispense with the addition of preservatives and propellants.
  • blowing agents are representatives of the fluorine-chlorine hydrocarbons, or fluorine hydrocarbons.
  • the use of these blowing agents is to be avoided today for reasons of environmental protection, since they destroy the ozone layer. From an economic point of view, the use of blowing agents is an additional cost factor.
  • the pump and valve sprays available on the market, which do not require any propellants for application, and nose drops contain active ingredients in aqueous solution. The problem with these aqueous solutions is that sterile manufacture is expensive and difficult. Contamination after opening can hardly be prevented without the addition of a preservative.
  • Preservatives often have a high allergy potential, so allergy sufferers often cannot use these medicines.
  • all common and approved preservatives are cytotoxic and impair the ciliary function and thus the clearance.
  • the addition of preservatives also means that preservation stress tests must be carried out on the pharmaceutical composition in order to achieve a sufficient level To ensure conservation. These tests are lengthy, time-consuming and costly.
  • Aqueous solutions are also relatively problematic in terms of their stability.
  • the strong pH dependence of the nasal absorption of active substances from aqueous solutions represents a further problem.
  • the optimal environment for the cilia of the nasal mucosa is between 7 and 9. However, the maximum absorption takes place at a pH value ⁇ 6. A pH value of 4 leads to the destruction of the cilia.
  • active substances also have an acid instability, so that at the pH value for optimal absorption a large part of the active substance is subject to a change in the chemical structure.
  • This chemically modified active ingredient has no pharmacological activity, so that the bioavailability and the therapeutic activity are greatly reduced.
  • a nasal application of acid-labile active ingredients has thus far hardly been possible.
  • Another possibility for nasal application of active substances is to enclose the active substance in liposomes and to apply this liposome formulation into the nose by means of pump sprays and the like or with the aid of propellants. The preparation of these liposome formulations is complex. The stability is low since the enclosed active ingredient dissolves from these liposomes over time, so that the amount of active ingredient actually applied decreases.
  • sterility can hardly be maintained over a longer period without the addition of preservatives, since a not inconsiderable proportion of water is included in the liposomes. This water inclusion poses a great risk of contamination by bacteria, fungi and viruses. Uptake through the nasal mucosa is also more difficult, since the active ingredient must first be released from the liposome vesicles in order to pass through the mucous membrane. Due to the natural clearance apparatus of the nasal cavity, an active substance applied to the nasal mucosa is transported to the throat within 10 to 20 minutes, from where this active substance is either expectorated or swallowed. Adequate absorption is therefore not always guaranteed with the liposome formulation.
  • the object of the invention is to provide a pharmaceutical composition for nasal use of water-insoluble or poorly water-soluble active ingredients in the form of a solution, the use of propellants and preservatives being unnecessary.
  • the object is achieved according to the invention by a pharmaceutical composition which contains at least one water-insoluble or poorly soluble active ingredient dissolved in a neutral oil.
  • the composition is essentially anhydrous.
  • Essentially water-free is understood here to mean a water content in the composition which can result from water of hydration, water of crystallization and / or residual moisture in the neutral oil, the active ingredients and / or the auxiliaries.
  • the pharmaceutical composition according to the invention can be applied to the nasal mucosa without the addition of propellants by means of devices which can produce a precisely defined dosage.
  • the preferred devices include common pump and valve sprays and nasal drops.
  • the composition has good absorption, since the solution adheres well to the nasal mucosa, the neutral oil also causes the cells to spread, and the active ingredient is thus very easily absorbed from the solution by the nasal mucosa.
  • the problem of the pH in aqueous solutions with regard to optimal absorption does not arise with the composition according to the invention.
  • Maximum absorption can be achieved without destroying the cilia, restricting their function or causing a change in the chemical structure of the active ingredient.
  • the composition is easy to filter, so that sterile filtration (0.2 ⁇ m pore size) can be used to produce a sterile solution without great effort.
  • the stability is very high, since even in the event of subsequent contamination, it is not possible for human-pathogenic microorganisms such as bacteria, fungi and viruses to multiply and survive in the neutral oil. Due to this fact, no preservative has to be added.
  • Damage to the nasal mucosa and impairment of the ciliary function by preservatives can thus be prevented, especially with long-term treatment, and complex, lengthy preservation stress tests can be dispensed with.
  • the tolerance of the oil solution according to the invention on the nasal mucosa is very good, so that irritation of the mucous membrane caused by the active ingredient and / or the auxiliaries is minimized and patient compliance can thus be increased.
  • neutral oil means medium-chain triglycerides. These can be obtained by esterification of medium-chain fatty acids such as capronic, capric, caprylic, lauric, myristic, linoleic and succinic acid, in particular capric, caprylic, linoleic and succinic acid with glycerol and / or propylene glycol ( Miglyol 810, 812, 818, 840).
  • the viscosity of the neutral oils used is 1-40 mPa s, in particular 5-20 mPa s, a viscosity of 8-15 mPa s is preferred.
  • the preferred neutral oil according to the invention is Miglyol 840.
