Definitions

  • the present invention relates to a method for the treatment of angina pectoris in humans .
  • Angina pectoris arises from an imbalance between myocardial oxygen supply and demand. Typically the condition results -from narrowing of the coronary arteries through atherosclerosis. This reduces blood flow, and thus oxygen supply, to the heart muscles, resulting in a severe cardiac oxygen deficiency which can cause severe pain to the sufferer. The condition can, in extreme form, be life-threatening. Attacks of angina pectoris are commonly brought on by exercise or by stress which increase oxygen demand in the cardiac muscles to a point where it cannot be met by the reduced supply of blood thereto.
  • European Patent Publication No. 0149519A discloses the use, in the treatment of heart failure, of quinolones of the following general formula (I) :
  • R- j _ is lower alkyl optionally substituted by hydroxy, - j __ alkoxycarbonyl or - ] __ ⁇ alkoxy; allyl; propynyl or phenyl-lower alkyl in which the phenyl ring is optionally substituted by 1 or 2 C- j __4 alkoxy groups or 1 or 2 C ⁇ __4 alkyl groups;
  • R 2 is C ⁇ __4 alkyl, ⁇ 2 - * i alkenyl or ⁇ ⁇ ⁇ alkynyl with the proviso that, when n is 0, R 2 is methyl; and
  • R3, R4 and R5, which may be the same or different, are hydrogen, lower alkyl, lower alkoxy, lower alkanoyl, halo, trifluoro ethyl or lower alkylthio.
  • ischaemic heart disease includes angina and myocardial infarction.
  • British Patent Application No. 8400905 makes no specific reference to use of the particular quinolone 7-fluoro-l-methyl-3-methyl sulphinylmethyl-4-quinolone in treatment of ischaemic heart disease in any form, still less in the particular . form known as angina pectoris.
  • this particular compound is a positive inotrope teaches the skilled worker away from use in treatment of angina pectoris.
  • angina pectoris results inter alia from cardiac oxygen deficiency caused by inadequate blood supply to the heart muscles. Accordingly, by causing the heart to work harder, the administration of a positive inotrope to a patient suffering from angina pectoris would be expected to exacerbate the existing oxygen deficiency by increasing oxygen demand in the very muscles where oxygen supply is scarce, thus causing a deterioration rather than an improvement, in the patient's condition.
  • the known vasodilatory action of the present quinolone might cause preferential vasodilation of non-ischaemic coronary vessels, thus diverting blood from diseased ischaemic coronary vessels and further reducing oxygen supply to the affected muscles of the heart.
  • This effect known as "coronary steal” might cause further deterioration in the condition of angina.
  • a method for the treatment of angina pectoris in a human in need of such treatment which comprises the administration to said human of a therapeutically effective amount of 7-fluoro-l-methyl-3-methylsulphinyl- 4-quinolone.
  • treatment includes the therapeutic treatment of a human suffering from angina pectoris and the prophylactic treatment of a human at risk from angina pectoris. Therefore, the invention includes a method of preventing angina pectoris attack in a human susceptible to such attack, by administering to said human an effective amount of 7-fluoro-l-methyl-3- methylsulphinyl-4-quinolone.
  • the method of the invention is used in the long term prophylactic management of angina attacks.
  • the method of the invention may be used in humans who do or do not suffer from heart failure.
  • the active compound denotes 7-fluoro-1-methyl-3-methylsulphiny1-4-quinolone
  • flosequinan is naturally converted into the corresponding sulphone compound 7-fluoro-1-methyl-3-methylsulphonyl-4-quinolone by metabolism following administration.
  • the active compound may be administered enterally or parenterally.
  • Enteral administration may be oral or rectal.
  • Parenteral administration may be intravenous, intramuscular, or topical.
  • Oral administration is preferred for the treatment of chronic angina, but intravenous administration may be preferred in treating the acute stage of the disease.
  • the active compound is generally administered in the form of a pharmaceutical composition
  • a pharmaceutical composition comprising the active compound together with a pharmaceutically acceptable carrier.
  • Such pharmaceutical compositions may take the form of any of the known pharmaceutical compositions for enteral or parenteral administration.
  • Pharmaceutically acceptable carriers suitable for use in such compositions are well known in the art of pharmacy.
  • the compositions of the invention suitably contain 0.1-90% by weight of active compound.
  • the compositions of the invention are often prepared in unit dosage form.
  • the active compound is administered in a dose of at least about 50 mg per day since it has been found that doses below about 50 mg do not always provide the benefit of the invention.
  • the dose is at least about 75 mg per day, suitably between 75 mg and 150 mg per day, preferably between 75 mg and 125 mg per day, for example about 100 mg per day.
  • the active compound is administered as a single dose, once a day.
  • This procedure has the advantage of being convenient to the patient and medical personnel alike, and minimises the risk that the administration of medication will be overlooked.
  • smaller doses could be provided several times a day to provide a total dose of the size described.
  • compositions for oral administration are the known pharmaceutical forms for such administration, for example tablets, capsules, syrups and aqueous or oily suspensions.
  • the excipients used in the preparation of these compounds are the excipients known in the pharmacist's art.
  • Tablets may be prepared by mixing the active compound with an inert diluent such as calcium phosphate in the presence of disintegrating agents, for example maize starch, and lubricating agents, for example magnesium stearate, and tableting the mixture by known methods.
  • Such tablets may, if desired, be provided with enteric coatings by known methods, for example by the use of cellulose acetate phthalate.
  • capsules for example hard or soft gelatin capsules, containing the active compound with or without added excipients, may be prepared by conventional means and, if desired, provided with enteric coatings in a known manner.
  • Other compositions for oral administration include, for example, aqueous suspensions containing the active compound in an aqueous medium in the presence of a non-toxic suspending agent such as sodium carboxymethylcellulose, and oily suspensions containing a compound of the present invention in a suitable vegetable oil, for example arachis oil.
  • compositions for use in the invention suitable for rectal administration are the known pharmaceutical forms for such administration, for example, suppositories with cocoa butter or polyethylene glycol bases.
  • Compositions for use in the invention suitable for parenteral administration are the known pharmaceutical forms for such administration, for example, sterile suspensions in aqueous and oily media or sterile solutions in a suitable solvent. Typically such forms might be solutions of glucose or sodium chloride.
