Norvasc and Celexa are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Norvasc belongs to Herz-Kreislauf-Medikamente while Celexa belongs to Antidepressiva. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation. Celexa: Citalopram hemmt selektiv den Serotonin-Reuptake-Transporter und erhöht damit die synaptische Serotoninverfügbarkeit, mit nur begrenzter Affinität zu Noradrenalin-Transportern oder anderen Rezeptoren.
When Norvasc is preferred
Norvasc ist bei Erwachsenen zur Behandlung der essenziellen arteriellen Hypertonie und der chronischen stabilen Angina pectoris sowie der vasospastischen Angina pectoris (Prinzmetal-Angina) zugelassen.
When Celexa is preferred
Celexa ist zugelassen zur Behandlung der Major Depression.
