Definitions

  • the present invention relates to a pharmaceutical composition comprising Nimorazole, which disintegrates in water.
  • the invention concerns a pharmaceutical composition such as a tablet comprising Nimorazole or a pharmaceutically acceptable salt thereof, for dispersion in water and administration via a tube to a patient with swallowing difficulties.
  • the patent US 4371540 describes the use of radiosensitizers for hypoxic cells. Administration is performed via an intravenous route or suggested to be done orally using a prodrug, wherein the prodrug is the acetate ester of the compound.
  • the patent US 4462992 suggests administration parenterally, subcutaneously, intravenously, intramuscularly or intraperitoneally, or alternatively oral administration.
  • Nimorazole is inter alia used to improve the efficacy of irradiation treatment for cancer patients.
  • cancer patients may suffer from swallowing difficulties.
  • Nimorazole treatment may have difficulties swallowing Nimorazole tablets, and thus have a need for having Nimorazole administered via an alternative route.
  • the amount of Nimorazole necessary for an effective treatment such as about 2 g for each treatment, aggravates this problem, as it implies the use of large tablets or a high number of tablets.
  • Nimorazole is slightly soluble in water (The Merck Index, 14 th Edition). Experiments indicate that the solubility in water is about 5 mg/ml. Further, in order to achieve a reasonable dissolution rate, it is usually necessary to apply excessive amounts of liquid in order to obtain sink conditions. Preparing a bulky solution of Nimorazole for further distribution creates additional problems in terms of storage stability and difficulties distributing a large container comprising liquid. There is a need for providing a liquid medium comprising an amount of Nimorazole exceeding the solubility limit of Nimorazole in water, in order to be able to administer effective amounts of Nimorazole via a feeding tube while avoiding the intake of excessive amounts of liquid medium.
  • the invention concerns a pharmaceutical composition
  • a pharmaceutical composition comprising Nimorazole or a pharmaceutically acceptable salt thereof, for disintegration in water or an aqueous medium and administration via a tube.
  • a feeding tube may suitably be used.
  • the invention concerns a pharmaceutical composition which allows administration using a feeding tube to a patient with swallowing difficulties.
  • the pharmaceutical formulation or tablet according to the invention preferably disintegrates upon contact with water, forming a dispersion.
  • the forming of the dispersion may be aided by stirring in the water, or shaking a container comprising the tablet and water.
  • the invention concerns a solid pharmaceutical composition
  • a solid pharmaceutical composition comprising Nimorazole or a pharmaceutically acceptable salt thereof, and further comprising: a disintegrant; optionally one or more additional excipients; and a coating; said pharmaceutical composition allowing administration via at least two different routes: i) oral administration, or
  • a pharmaceutical formulation or tablet which may be used directly for oral administration, and which alternatively may be dispersed in water in a short time frame for administration via a feeding tube.
  • the pharmaceutical formulation or tablet may be dispersed in a small volume of water.
  • the dispersed particles are sufficiently small to provide a slow sedimentation rate, allowing administration of the particles in dispersed state from e.g. a bottle via a feeding tube.
  • a pharmaceutical formulation in the form of a tablet is easy to handle and dosage may easily be measured and subsequently checked.
  • Using a powder from individual sachets makes a dosing of several sachets cumbersome.
  • the use of a powder makes a dosage check after measurement of the intended dosage cumbersome, while a small number of tablets are easily counted for verification of dosage.
  • a tablet provides a smaller surface area than a powder, thus potentially increasing the storage stability of the product.
  • the invention concerns a kit of parts comprising a pharmaceutical composition according to the invention, and instructions for preparing a dispersion of said pharmaceutical composition for administration via a tube.
  • the invention concerns a method for manufacturing a pharmaceutical formulation or tablet according to the invention, comprising wet granulation of Nimorazole.
  • the invention concerns a method of treatment of cancer, wherein irradiation treatment is combined with the administration of at least one pharmaceutical formulation or tablet according to the invention, wherein said at least one pharmaceutical formulation or tablet is allowed to disintegrate in water or an aqueous medium and administered via a tube.
  • irradiation treatment is combined with the administration of at least one pharmaceutical formulation or tablet according to the invention, wherein said at least one pharmaceutical formulation or tablet is allowed to disintegrate in water or an aqueous medium and administered via a tube.
  • the invention concerns a method of radiosensitizing hypoxic tumor cells comprising administering Nimorazole, wherein the administration comprises: providing a solid pharmaceutical composition comprising Nimorazole or a pharmaceutically acceptable salt thereof; dispersing said solid pharmaceutical composition in water or an aqueous medium to obtain a dispersion; and administering said dispersion via a tube.
  • the invention concerns a use of a tablet according to the invention, wherein said tablet is dispersed in water and administered via a tube.
  • the invention concerns an aqueous pharmaceutical composition
  • aqueous pharmaceutical composition comprising Nimorazole or a pharmaceutically acceptable salt thereof, wherein at least part of said Nimorazole or pharmaceutically acceptable salt thereof is dispersed in an aqueous medium in form of solid particles.
  • the invention concerns a pharmaceutical composition
  • a pharmaceutical composition comprising Nimorazole or a pharmaceutically acceptable salt thereof, for disintegration in water or an aqueous medium and administration via a tube.
  • a feeding tube may suitably be used.
  • water or an aqueous medium covers the possibility of using water or water comprising one or more salts, such as a saline solution, and/or any (other) components for the patient, such as at least one active ingredient. It also covers the possibility of water comprising one or more nutrients, optionally with one or more active ingredients.
  • the pharmaceutical composition or tablet according to the invention preferably disintegrates upon contact with water, forming a dispersion. The forming of the dispersion may be aided by stirring in the water, or shaking a container comprising at least one tablet and water.
  • the invention concerns a pharmaceutical composition or a tablet for administration to a patient with swallowing difficulties.
  • the invention concerns a pharmaceutical composition or tablet for administration to a patient with little, insufficient or no saliva, such as a patient with non-normal salivary function.
  • the invention concerns a solid pharmaceutical composition

  • the solid pharmaceutical composition is preferably a tablet.
  • the pharmaceutical composition is preferably provided in a solid form which is stable over time.
  • the pharmaceutical composition is stable for 6 months, preferably 12 months, more preferred 18 months, preferably 24 months, more preferred 30 months, preferably 36 months, or even longer.
  • the pharmaceutical composition retains its dispersibility upon storage, i.e. during storage for 6 months, preferably 12 months, more preferred 18 months, preferably 24 months, more preferred 30 months, preferably 36 months, or even longer.
  • the disintegrant makes it possible to provide a dispersion in a short time interval.
  • the solid pharmaceutical composition allows the provision of a dispersion comprising an amount of Nimorazole or a pharmaceutically acceptable salt thereof, wherein the amount of Nimorazole or a pharmaceutically acceptable salt thereof exceeds the solubility limit of Nimorazole in the water or the aqueous medium.
  • the solid pharmaceutical composition allows the provision of a dispersion comprising an amount of Nimorazole or a pharmaceutically acceptable salt thereof, wherein the amount of Nimorazole or a pharmaceutically acceptable salt thereof exceeds the 5 mg / ml of water or the aqueous medium.
  • the coating may serve as taste-masking, as Nimorazole has an unpleasant taste. An unpleasant taste may lower patient compliance. Additionally, a coating may improve storage stability of the pharmaceutical formulation.
  • Having a pharmaceutical composition which allows two different routes of administration carries a number of advantages. Firstly, patient compliance is improved, as the patient is already used to the pharmaceutical composition if or when the patient needs to change route of administration. Secondly, the costs associated with production and obtaining marketing approval are lowered, as only one product needs to be produced and approved.
  • the dispersion of the solid pharmaceutical composition may be done by the patient. It is further preferred that administration of the dispersion may be performed by the patient. This allows out-patient or ambulatory use.
  • An excipient is generally a pharmacologically inactive substance. Examples include, but are not limited to, diluents, disintegrants, binders, glidants, lubricants, and coatings. Other examples of suitable excipients may be found in Handbook of Pharmaceutical Excipients, 7 th Ed. by owe, Raymond C. et al., Pharmaceutical Press, London.
  • Diluents are inactive ingredients that are added to tablets and capsules in addition to the active drug. Some very common diluents in tablets include starch, cellulose derivatives, and magnesium stearate (also a lubricant). Diluents fill out the size of a tablet or capsule, making it practical to produce and convenient for the consumer to use. By increasing the bulk volume, diluents make it possible for the final product to have the proper volume for patient handling. A good diluent must be inert, compatible with the other components of the formulation, non-hygroscopic, relatively cheap, compactible, and preferably tasteless or pleasant tasting. Plant cellulose (pure plant Diluent) is a popular diluent in tablets or hard gelatin capsules.
  • Dibasic calcium phosphate is another popular tablet diluent.
  • a range of vegetable fats and oils can be used in soft gelatin capsules.
  • Other examples of diluents include: lactose, sucrose, glucose, mannitol, sorbitol, calcium carbonate, and magnesium stearate.
  • Disintegrants expand and dissolve when wet causing the tablet to break apart. They ensure that when the tablet is in contact with water, it rapidly breaks down into smaller fragments, facilitating dissolution or dispersion.
  • disintegrants include, but are not limited to: crosslinked polymers, such as crosslinked polyvinylpyrrolidone (crospovidone), and crosslinked sodium carboxymethyl cellulose (croscarmellose sodium); and the modified starch sodium starch glycolate. Specific examples further include Indion 414, L-HPC, and pregelatinised starch.
  • Binders hold the ingredients in a tablet together. Binders ensure that tablets and granules can be formed with required mechanical strength, and give volume to tablets.
  • binders include: saccharides and their derivatives: disaccharides, sucrose, lactose; polysaccharides and their derivatives, such as starches, cellulose or modified cellulose, such as microcrystalline cellulose and cellulose ethers such as hydroxypropyl cellulose (HPC); sugar alcohols such as xylitol, sorbitol or maltitol; further Protein: gelatin; and Synthetic polymers: polyvinylpyrrolidone (PVP), polyethylene glycol (PEG). Examples include gelatin, cellulose, cellulose derivatives,
  • polyvinylpyrrolidone starch, sucrose and polyethylene glycol.
  • Other examples include cellulose, methyl cellulose, polyvinylpyrrolidone and polyethylene glycol.
  • Glidants are used to promote powder flow by reducing interparticle friction and cohesion. These are used in combination with lubricants as they have no ability to reduce die wall friction.
  • Examples include fumed silica, talc, and magnesium carbonate.
  • Lubricants are agents added to tablet and capsule formulations to improve certain processing characteristics. Lubricants inter alia prevent ingredients from clumping together and from sticking to the tablet punches or capsule filling machine. Lubricants also ensure that tablet formation and ejection can occur with low friction between the solid and die wall. Common minerals like talc or silica, and fats, e.g. vegetable stearin, magnesium stearate or stearic acid are examples of lubricants used in tablets or hard gelatin capsules.
  • Coatings protect ingredients from deterioration by moisture in the air and make large or unpleasant-tasting tablets easier to swallow.
  • a cellulose ether hydroxypropyl methylcellulose (HPMC) film coating is used which is free of sugar and potential allergens.
  • other coating materials are used, for example synthetic polymers, shellac, corn protein zein or other polysaccharides.
  • a specific example is Opadry.
  • Capsules are coated with gelatin.
