Mechanism and action
Norvasc: Amlodipine selectively blocks L-type calcium channels in vascular smooth muscle, reducing transmembrane calcium influx and producing peripheral arterial vasodilation. Lantus: Insulin glargine binds the insulin receptor with similar affinity to human insulin, activating intracellular signalling that increases glucose uptake in muscle and adipose tissue, suppresses hepatic glucose production an…

Frequently asked questions
Is Norvasc or Lantus better? ▾

Can I switch from Norvasc to Lantus? ▾
Switching between Norvasc and Lantus is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.

No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
