Additive hypotensive effects Click to Show/Hide Mechanism Graph

Drug Name		Minoxidil				Canagliflozin
Mechanism 1		Antihypertensive agent ATP-sensitive inward rectifier potassium channel Inducer				Antihypertensive agent
Key Mechanism Factor 1
		Factor Name		Inward rectifier potassium channel				Structure Sequence
		Protein Family		Inward rectifier-type potassium channel (TC 1.A.2.1) family
		Protein Function		This receptor is controlled by G proteins. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by extracellular barium (By similarity). Subunit of ATP-sensitive potassium channels (KATP). Can form cardiac and smooth muscle-type KATP channels with ABCC9. KCNJ11 forms the channel pore while ABCC9 is required for activation and regulation. Click to Show/Hide
Mechanism Description		Additive hypotensive effects by the combination of Minoxidil and Canagliflozin

Recommended Action
Management		Caution is advised if SGLT-2 inhibitors are coadministered with diuretics and other hypotensive agents, particularly in the elderly and patients with impaired renal function. Prior to initiating SGLT-2 inhibitors, volume status should be assessed and corrected, if necessary. Clinical and laboratory monitoring are recommended during therapy, including electrolytes, fluid status, renal function, and blood pressure. If volume depletion occurs, treatment with SGLT-2 inhibitors should be interrupted until the condition is corrected.
