As a result, it causes issues like irregular pulse and cardiac disorders. Olmesartan medoxomil and chlorthalidone are the two medications included in one tablet, Olkem CT 20. Olmesartan medoxomil is an angiotensin receptor blocker (ARB), which relaxes blood arteries by inhibiting the hormone angiotensin.
