Description
Ivabradine hydrochloride, also known as Procoralan, is a white to off-white solid that is a hydrochloride obtained by combining ivabradine with one molar equivalent of hydrochloric acid. It is a specific inhibitor of the If current, which is the primary pacemaking current in the sinoatrial (SA) node of the heart. By interacting with f-channels on the intracellular side of the plasma membrane, ivabradine hydrochloride reduces the speed of diastolic depolarization and decreases heart rate.
Uses
Used in Angina Therapeutic Applications:
Ivabradine hydrochloride is used as a heart rate-lowering agent for the treatment of chronic stable angina. It acts specifically on the pacemaker activity of the sinoatrial node, providing a viable alternative to patients with contraindications or intolerance of beta-blockers.
Used in Antianginal Applications:
Ivabradine hydrochloride is used as a selective bradycardic agent with a direct effect on the pacemaker If current of the sinoatrial node. It helps in the treatment of angina by reducing the heart rate, which in turn decreases the oxygen demand of the heart and alleviates the symptoms of angina.
Used in Cardiology:
Ivabradine hydrochloride is used as a potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel (HCN) blocker in embryoid body (EB) and rat engineered heart tissue (EHT). This application aids in the study and understanding of the role of If current in the regulation of heart rate and its potential implications in the development of new treatments for cardiovascular diseases.
Used in Drug Development:
Ivabradine hydrochloride is used in the development of new heart-rate reducing compounds that act specifically on the sinoatrial (SA) node. These bradycardic agents are explored as an alternative to traditional b-adrenergic blockers and calcium channel blockers, which may have unwanted negative inotropic and hypotensive effects.

Drug interactions
Potentially hazardous interactions with other drugs
Anti-arrhythmics: increased risk of ventricular
arrhythmias with amiodarone and disopyramide.
Antibacterials: concentration possibly increased by
clarithromycin and telithromycin - avoid; increased
risk of ventricular arrhythmias with erythromycin -
avoid.
Antifungals: concentration increased by ketoconazole
- avoid; concentration increased by fluconazole -
reduce initial ivabradine dose; concentration possibly
increased by itraconazole - avoid.
Antimalarials: increased risk of ventricular
arrhythmias with mefloquine.
Antipsychotics: increased risk of ventricular
arrhythmias with pimozide.
Antivirals: concentration possibly increased by
ritonavir - avoid.
Beta-blockers: increased risk of ventricular
arrhythmias with sotalol.
Calcium-channel blockers: concentration increased
by diltiazem and verapamil - avoid.
Grapefruit juice: ivabradine concentration increased.
Pentamidine: increased risk of ventricular
arrhythmias.
St John’s wort: ivabradine concentration reduced -
avoid.
Metabolism
Ivabradine is extensively metabolised by the liver
and the gut by oxidation through cytochrome P450
3A4 (CYP3A4) only. The major active metabolite is
N-desmethyl-ivabradine (S 18982) with an exposure
about 40% of that of the parent compound. This active
metabolite undergoes further metabolism by CYP3A4.
Excretion of metabolites occurs to a similar extent via
faeces and urine.
Check Digit Verification of cas no
The CAS Registry Mumber 148849-67-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,8,4 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 148849-67:
(8*1)+(7*4)+(6*8)+(5*8)+(4*4)+(3*9)+(2*6)+(1*7)=186
186 % 10 = 6
So 148849-67-6 is a valid CAS Registry Number.

Paragraph 0056-0062, (2019/12/02)
The invention discloses a preparation method of high-purity ivabradine hydrochloride and an intermediate thereof. According to the invention, a specific refining method is adopted; by-products generated in the preparation process are effectively removed, wherein the byproducts refer to an impurity shown in a formula I and an impurity shown in a formula II. Results confirm that the purity of the ivabradine intermediate shown in the formula IV is remarkably improved, and the contents of the impurity compound shown in the formula I and the impurity shown in the formula II in the ivabradine intermediate shown in the formula IV are controlled within the range of less than 0.1%, so that the purity of the subsequently prepared ivabradine hydrochloride can be improved. And in the process of preparing ivabradine hydrochloride by using the prepared ivabradine intermediate shown in the formula IV, impurities shown in the formula II are further removed by re-utilizing a recrystallization mode of amixed solution of acetyl chloride, acetone and ethanol. The impurity shown in the formula I and the impurity shown in the formula II obtained by separation can be used as impurity reference substances for quality control of an ivabradine raw material and a preparation thereof.
