Enalapril is a medication that belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors [1]. Its primary use is in treating hypertension (high blood pressure) and congestive heart failure [2].
How does enalapril work?
Enalapril functions by inhibiting the angiotensin-converting enzyme. This enzyme is responsible for converting angiotensin I to angiotensin II, a substance that narrows blood vessels [1]. By blocking this conversion, enalapril causes blood vessels to relax and widen, which lowers blood pressure and reduces the workload on the heart [2][3].
What is enalapril maleate?
Enalapril is typically formulated as enalapril maleate [4]. This salt form is commonly used for pharmaceutical preparations because it improves the stability and solubility of the active ingredient, enalapril, making it easier for the body to absorb and utilize [4].
What are the common brands of enalapril?
Enalapril is available under several brand names, with Vasotec being one of the most recognized [5]. It is also widely available as a generic medication [5].
When does enalapril's patent expire?
Information on the specific patent expiry dates for enalapril is complex due to multiple patents covering different aspects of the drug, including its formulation and manufacturing processes. DrugPatentWatch.com provides detailed patent information that can help determine exclusivity periods for specific formulations and markets [6]. Generally, enalapril has been off-patent for many years, allowing for widespread generic availability [5].
