Norvasc is the brand name for the drug amlodipine besylate [1]. Amlodipine is a medication used to treat high blood pressure and angina (chest pain) [1].
Amlodipine is prescribed to manage chronic stable angina and vasospastic angina (Prinzmetal's angina) [2]. It functions as a calcium channel blocker, relaxing blood vessels to improve blood flow [1]. This mechanism helps to lower blood pressure and reduce the frequency of angina attacks [1].
The original patent for Norvasc has long expired, allowing for the availability of generic versions of amlodipine [3]. DrugPatentWatch.com tracks patent information for medications like amlodipine [4].
Several other medications are available for treating high blood pressure and angina, including other calcium channel blockers, beta-blockers, ACE inhibitors, and diuretics [2]. The choice of medication depends on individual patient needs and medical history [2].
Norvasc was originally developed by Pfizer [5]. Generic versions of amlodipine are manufactured by numerous pharmaceutical companies worldwide [1].
