Abstract

Ivabradine hemipamoate of formula (I):

and its hydrates.

Medicinal products containing the same which are useful in the treatment or prevention of the various clinical situations of myocardial ischaemia such as angina pectoris, myocardial infarction and the associated rhythm disturbances, as well as in the various pathologies involving rhythm disturbances, especially supraventricular rhythm disturbances, and in systolic or diastolic heart failure.

First claim

The invention claimed is:

1. Ivabradine hemipamoate of formula (I):

2. A process for the preparation of ivabradine hemipamoate according to claim 1 , wherein ivabradine hydrochloride is brought together with sodium pamoate in an aqueous medium in a proportion ivabradine hydrochloride/sodium pamoate of from 1/0.5 to 1/0.6, to form ivabradine hemipamoate of formula (I), which ivabradine hemipamoate is then extracted from the aqueous medium by means of an organic solvent, followed by removal of the solvent under vacuum, to yield ivabradine hemipamoate.

3. A pharmaceutical composition comprising as active ingredient ivabradine hemipamoate according to claim 1 , in combination with one or more inert, non-toxic, pharmaceutically acceptable excipients or carriers.

4. A method of treating a condition selected from the group consisting of clinical situations of myocardial ischaemia; pathologies involving rhythm disturbances; and systolic or diastolic heart failure, in a subject in need thereof, comprising administration of an effective amount of ivabradine hemipamoate according to claim 1 , alone or in combination with one or more inert, non-toxic, pharmaceutically acceptable excipients or carriers.

5. The method of claim 4 , wherein the condition is selected from the group consisting of angina pectoris and myocardial infarction and the associated rhythm disturbances.
