Norvasc belongs to Cardiovascular Medications while Trulicity belongs to Diabetes Treatment. 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: Amlodipine selectively blocks L-type calcium channels in vascular smooth muscle, reducing transmembrane calcium influx and producing peripheral arterial vasodilation. Trulicity: After subcutaneous injection, dulaglutide is gradually absorbed and circulates with greater than 99% albumin binding.
When Norvasc is preferred
Norvasc is approved in adults for the treatment of essential hypertension and chronic stable angina, and for vasospastic (Prinzmetal's) angina.
When Trulicity is preferred
The medication is indicated in adults with type 2 diabetes mellitus, alone or in combination with other antidiabetic agents, to improve glycaemic control.
