Definitions

  • the present invention relates to novel, stable and pharmacologically acceptable salts of L-carnitine and lower alkanoyl L-carnitines which favourably lend themselves to the preparation of orally, parenterally or sublingually administrable compositions which can be both solid or, thanks to the salt water solubility, liquid as well.
  • the compositions are useful in the field of dietary and dietetic supplements, health foods, and nutraceutical in addition to the strict pharmaceutical field.
  • the invention also relates to the compositions thus obtained.
  • L-carnitine is used in the cardiovascular field as a support drug for the treatment of acute and chronic myocardial ischaemia, angina pectoris, heart failure and cardiac arrhythmias.
  • L-carnitine is administered to chronic uraemics undergoing regular haemodialytic treatment to combat myasthenia and the onset of muscular cramps.
  • Acetyl L-carnitine is used in the neurologic field for the treatment of both central nervous system disturbances and peripheral neuropathies, particularly diabetic peripherial neuropathy.
  • Propionyl L-carnitine is used for the treatment of chronic arteriosclerosis obliterans, particularly in patients showing the symptom of severely disabling intermittent claudication.
  • L-carnitine supplies energy to the skeletal musculature and increases the resistance to prolonged, intense stress, enhancing the performance capability of such individuals.
  • L( ⁇ )-carnitine or its lower alkanoyl derivatives constitute indispensable nutritional supplements for both vegetarians, whose diet have a low carnitine content as well as a low content of the two amino acids, lysine and methionine (the precursors of the biosynthesis of L(—)-carnitine in the kidneys and liver) and for those subjects who have to live on a diet poor in protein for prolonged periods of time.
  • compositions containing L-carnitine alone or in combination with other active ingredients have recently reached the market of the health foods, dietary supplements, energy foods and similar products, i.e. those compositions which sold as OTCs are not addressed to purely therapeutic purposes, but are aimed to the well-being and at producing a general improvement in fitness and performances on the part of the consumer and which have recently termed “nutraceuticals”.
  • L-carnitine is not generally used in the form of its inner salt, owing to the extremely high hygroscopicity thereof
  • L-carnitine inner salt's hygroscopicity brings about complex problems of processing, stability and storage both of the raw materials and of the finished products.
  • L( ⁇ )-carnitine tablets have to be packaged in blisters to keep them out of contact with the air, since, otherwise, even in the presence of normal humidity conditions, they would undergo alterations, swelling up and becoming pasty and sticky.
  • traces of trimethylamine are released which give the products as unpleasant fishy odour.
  • the object of the present invention is to provide such novel, stable pharmacologically acceptable salts of L-carnitine and lower alkanoyl L-carnitines which not only possess an enhanced therapeutical and/or nutritional efficacy with respect to the corresponding inner salts, but also, owing to their water solubility, are more easily absorbable resulting in higher haematic concentration of L-carnitine in shorter times with respect to those achievable with L-carnitine inner salt or its pharmacologically acceptable salts known to-date.
  • the aforesaid object is achieved via the L-carnitine and lower alkanoyl L-carnitines alpha-ketoglutarates having the formula:
  • a ⁇ is the alpha-ketoglutarate anion
  • R is hydrogen or a straight- or branched-chain lower alkanoyl having 2-5 carbon atoms.
  • R is alkanoyl, it is preferably selected from the group consisting of acetyl, propionyl, valeryl and isovaleryl.
  • alpha-ketoglutarates of the invention are the following:
  • valeryl L-carnitine alpha-ketoglutarate
  • alpha-ketoglutarate of the invention present the favourable metabolic properties of both L-carnitine or alkanoyl L-carnitine and alpha-ketoglutaric acid with a synergistic effect.
  • alpha-ketoglutaric acid plays an important metabolic role, which is correlated to that played by L-carnitine.
  • Alpha-ketoglutarate administration has been also successfully adopted in cardiac surgery owing to the important role played by alpha-ketoglutaric acid in the Krebs cycle and, hence, in myocardial metabolism. Consequently, its use as cardioprotective agent has been suggested. Since alpha-ketoglutaric acid can act as mitochondrial carrier, just as carnitine does, and can, therefore, similarly to carnitine, correct some so-called mitochondriocytopathies, its favourable metabolic effects not only at the cardiac level but also at the level of other organs such as the renal tract can be accounted for.
  • Example 2 The procedures of Example 1 were repeated, substituting mannitol for glucose.
  • the product obtained simply by water evaporation can be manufactured as capsules which rapidly dissolve when placed under the tongue or in the oral cavity.
  • L-carnitine alpha-ketoglutarate can be stabilized by adding thereto glucose, fructose, lactose or mannitol or other sugars, as shown in Examples 1-4.
  • L-carnitine alpha-ketoglutarate spreads evenly, infact, on the solid base consisting of lactose, fructose, glucose or mannitol, resulting in a well preservable powder.
  • the end product can be supplemented with stabilizers and preservatives currently used in pharmaceutical preparations or dietary/nutritional supplements, or with other active ingredients selected from drugs, nutrients and dietetic agents such as vitamins, amino acids, mineral salts or products of vegetable origin.
  • ATP concentrations were monitored according to the method described by Strehler (Strehler B. L., Methods in Enzymology 111, N.Y. Acad. Press. 879, 1957) on tissue samples held in the anoxic state for a period of 90 minutes.
  • compositions of the present invention include tablets, chewable tablets, pills, troches, lozenges, capsules, powders, granulates, phials, solutions, elixirs or drops.
  • the compositions comprise an amount of a ketoglutarate of L-carnitine or alkanoyl L-carnitine corresponding to about 50-1000 mg, preferably about 100-500 mg, of L-carnitine or alkanoyl L-carnitine as inner salts.
  • one of such a composition comprises L-carnitine alpha-ketoglutarate mg 500 Cocarboxylase mg 2 Vit. B 6 mg 5 Vit. E mg 5 Vit. PP mg 20 Vit. C mg 50 Coenzyme Q 10 mg 25 Selenomethionine ⁇ g 50 Magnesium mg 25 Calcium mg 25 Zinc mg 3
  • a mixture of L-carnitine alpha-ketoglutarate with one or more alkanoyl L-carnitine alpha-ketoglutarate may suitably substitute for L-carnitine alpha-ketoglutarate alone; for example (with reference to the previous composition): L-carnitine alpha-ketoglutarate mg 200 Acetyl L-carnitine alpha-ketoglutarate mg 200 Propionyl L-carnitine alpha-ketoglutarate mg 200
