Manidón belongs to a group of medications known as calcium channel blockers, with a predominantly cardiac action. These medications are used to treat chest pain, high blood pressure, or irregular heart rhythm.

Injectable Manidón is used in the treatment of supraventricular tachycardias, including:

-Paroxysmal supraventricular tachycardia, even when associated with accessory conduction pathways (Wolf-Parkinson-White syndrome, Lown-Ganong-Levine syndrome). When clinically justified, vagal tone-stimulating maneuvers will be performed as the first measure.

-Atrial flutter or fibrillation, except when associated with the existence of accessory conduction pathways (Wolf-Parkinson-White syndrome, Lown-Ganong-Levine syndrome).

No use Manidón

• If you are allergic to hydrochloride verapamil or any of the other components of this medication (listed in section 6).
• If you have any of the following heart conditions:

• Cardiogenic shock (the heart is unable to pump enough blood that the body needs).
• Severe hypotension.
• Second- or third-degree atrioventricular block (conduction disorder between the atria and ventricles of the heart), except if there is an implanted pacemaker.
• Heart block (problems with the heart rhythm), except if there is an implanted pacemaker.
• Severe congestive heart failure, except if it is secondary to a supraventricular tachycardia that can be treated with verapamil.
• Atrial flutter or fibrillation (abnormal heart rhythms).
• Ventricular tachycardia.

• If you are receiving intravenous beta-adrenergic blockers.

• If you are taking a medication that contains ivabradina for the treatment of certain heart conditions.
