Abstract
Hypertension is considered a major health problem around the world. It's associated with increasing risk of mortality due to its complication which has a great impact on patient's life quality. Angiotensin Receptor Blocker has been widely used to manage hypertension, especially if diabetes coexists and the patient is less tolerable to angiotensin-converting enzyme inhibitors. In particular, telmisartan has been studied either as a monotherapy or combined with other antihypertensive agents. This study aims to understand the efficacy, safety, and tolerability of telmisartan as monotherapy or, in combination, is it superior to other agents? We used the PubMed database to search for relevant articles on the topic. Telmisartan administration showed excellent 24-hour protection against elevated BP, particularly in the early morning BP surge, which is the most expected period where cardiovascular events or strokes occur. In patients resistant to monotherapy, the use of telmisartan combinations provides better BP control compared to other agents, especially in the triple combination, where the drug's side effects are significantly decreased.
