Final answer:
The mnemonic 'RAS Regulators' is associated with ACE inhibitors and ARBs, which both act on the Renin-Angiotensin System to control blood pressure and fluid balance in the body.
Step-by-step explanation:
The mnemonic device associated with ACE inhibitors and ARBs (Angiotensin Receptor Blockers) is the phrase "RAS Regulators". This term relates to how both of these medications act on the Renin-Angiotensin System (RAS), which plays a crucial role in regulating blood pressure and fluid balance in the body. ACE inhibitors, such as Lisinopril, block the angiotensin-converting enzyme that converts angiotensin I to the potent vasoconstrictor angiotensin II, thereby lowering blood pressure and reducing the workload on the heart. ARBs, like Losartan (Cozaar) and Valsartan (Diovan), selectively block the binding of angiotensin II to its receptors, leading to similar effects as ACE inhibitors but through a different mechanism.
