Temocapril is used primarily in the management of hypertension. It functions by inhibiting the angiotensin-converting enzyme (ACE), which reduces the production of angiotensin II, a substance that constricts blood vessels and promotes sodium retention. By blocking this pathway, temocapril helps relax blood vessels, lower blood pressure, and improve overall cardiovascular function. It is particularly beneficial in patients with impaired kidney function, as it has a tissue-selective action and is activated in the liver, allowing for more targeted effects. This property may reduce systemic side effects commonly associated with other ACE inhibitors. Temocapril is also considered useful in patients with heart failure or those at risk of cardiovascular events, supporting long-term heart health when used as part of a comprehensive treatment plan.
