Definitions

  • This invention relates to improved treatment of patients having conditions which are .susceptible to treatment with racemic verapamil, but who are disposed to constipation as a side effect thereof.
  • Verapamil (1) is presently in clinical use as a racemate for the treatment of hypertension, angina, atrial fibrillation and paroxysmal supraventricular tachycardia.
  • constipation is a well known and undesirable side effect of this drug, with a reported incidence up to 38% of .all patients treated; see C. Yedinak, American Pharmacy (1993) NS 33:8; 49-66. This can result in reduced compliance or even cessation of treatment.
  • the opposite enantiomers of verapamil have different biological activities and different potencies.
  • the ph-armacological profile is determined by stereoselectivity of pharmacodynamics and pharmacokinetics.
  • the (R)-enantiomer may be of benefit for the reversal of multi-drug resistance in cancer chemotherapy (see Eliason, Int. J. Cancer (1990) 46: 113).
  • the (S)-enantiomer may be of benefit in the treatment of atrial fibrillation (see Raschack, Naunyn-Schmiedeburg's Arch. Pharmacol. (1976) 294: 285-297). It may also be of benefit in the treatment of angina (see Curtis et al., Br. J. Pharmac. (1986) 89: 137-147), although dose-limiting side effects are reported to be associated with its use, such as depression in myocardial activity (see Satoh et al, Journal of Cardiovascular Pharmacology (1980) 2 : 309-318) and atrioventricular (AV) conduction block (see Raschack, as above). Summary of the Invention
  • a patient disposed to constipation typically we mean a patient who suffers from a difficult or infrequent p.assage of faeces after treatment with a standard treatment dosage, eg. 360 mg per day, of verapamil racemate; a patient whose colon does not respond to the usual stimuli providing evacuation of the colon; or a patient in whom accessory stimuli normally provided by eating or physical exercise are lacking, eg. a bedridden patient.
  • a standard treatment dosage eg. 360 mg per day
  • verapamil racemate eg. 360 mg per day
  • the use of drugs for medical conditions usually associated with constipation frequently compounds the problem, eg. opiates and anti-depressants.
  • patients suffering from neurological diseases, such as Parkinson's disease frequently suffer from constipation..
  • substantially single enantiomer typically we mean that the desired enantiomer is in an enantiomeric excess of at least 70% by weight as compared to the other enantiomer, preferably at least 95%, or higher.
  • the enantiomer may be enantiopure. It may be used in the form of any suitable salt, eg. the hydrochloride.
  • the utility of the present invention lies in the trr ⁇ tment of any condition susceptible to treatment by verapamil racemate. Patients for which it may have particular utility include tho.se who are cardiac-compromised, and therefore ill-equipped to cope with strain that may result from constipation.
  • cardiac-compromised typically we mean a patient suffering from any form of heart disease, and in particular from any of the following conditions: atrial fibrillation, angina, hypertension, and paroxysmal supraventricular t hycardia. It may also have utility in non-vascular conditions, for instance in multi-drug resistance reversal, eg. in chemotherapy, and any other condition for which verapamil racemate may have utility.
  • (.S)-verapamil has been suggested for the treatment of atrial fibrillation and angina. Accordingly, urther embodiments of the present invention utilise ( ⁇ verapamil for the treatment of patients suffering either from atrial fibrillation or angina, and who are disposed to constipation.
  • Administration of the single enantiomer may be by any of the conventional routes, for instance oral and sublingual. Conventional formulations may be used, including sustained-release formulations where appropriate.
  • the single enantiomer will be formulated for oral administration.
  • the dosage of the single enantiomer will typically depend upon the condition to be treated and/or the particular patient to be treated. Typically, however, the dosage will be lower than that usually used with the racemate, for instance up to 240 mg per day, and preferably not exceeding 200 mg per day. This is particul.arly true in the case of administration of (S)- verapamil for the treatment of angina, where side effects reported to be associated with this enantiomer may be particularly harmful at high dosages.
  • verapamil racemate and the individual enantiomers of verapamil on gastrointestinal transit were studied in 13 male volunteers in a four-way double blind cross-over study. All volunteers consumed a standard balanced diet throughout the period. In each phase of the study, each volunteer was assigned to one of four groups which received the following treatments, three times a day, over a period of 7 days.
  • Group A 120 mg racemic verapamil hydrochloride (a total of 360 mg drug per day).
  • Group B 60 mg (S)-verapamiI hydrochloride (a total of 180 mg drug per day).
  • Group C 60 mg (R)- verapamil hydrochloride (a total of 180 mg drug per day).
  • Group D - 320 mg Placebo (a total of 960 mg per day).
  • the volunteers were also administered a capsule containing ⁇ n In-labelled ion-exchange resin, to act as a marker of gastrointestinal transit. The minimum time interval between separate study periods was 7 days.
