Mechanism		Prolong QT interval				Prolong QT interval
Key Mechanism Factor 1
		Factor Name		QT interval
		Factor Description		Long QT syndrome is a heart signaling disorder that can cause a fast, chaotic heartbeat (arrhythmia). Many people may not exhibit symptoms, and usually the condition is detected during routine medical tests. In others, the most common symptoms include: sudden fainting, palpitations, dizziness, seizures, sudden death.
Mechanism Description		Increased risk of prolong QT interval by the combination of Iloperidone and Amisulpride

Recommended Action
Management		Coadministration of iloperidone with other drugs that can prolong the QT interval should generally be avoided. Caution and clinical monitoring are recommended if concomitant use is required. Patients should have regular ECGs and be monitored for arrhythmias when QT interval is prolonged. Persistent QTc measurements exceeding 500 msec will require suspension of iloperidone therapy and immediate action to correct any concomitant risk factors before resuming treatment.
