Management of Ischemic Heart Disease With Angiwell-XR (Ranolazine)

Overview

The rationale of MIDA trial is to determine efficacy and tolerability of ranolazine molecule among Pakistan population and obtain firsthand knowledge about the molecule ranolazine.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: N/A
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: September 30, 2018

Interventions

  • Drug: Ranolazine
    • Ranolazine inhibits sodium and potassium ion channel currents. Inhibition of the late phase of the inward sodium current during cardiac repolarization has been well studied4. In disease states, enhanced sodium-calcium exchange due to augmented late phase of the inward sodium current activity leads to increased cytosolic calcium concentration. Intracellular calcium overload is believed to be critical to the mechanism of decreased left ventricular relaxation caused by ischemia and reperfusion. Elevated left ventricular diastolic wall tension compromises myocardial blood flow even further.

Arms, Groups and Cohorts

  • Other: Ranolazine
    • Ranolazine was approved by the U.S. Food and Drug Administration in 2006 in 500 mg and 1000 mg extended-release doses, advising 500 mg BID as a starting dose and 1000 mg BID as maximum dose

Clinical Trial Outcome Measures

Primary Measures

  • Efficacy: Reduction in frequency of Angina with Ranolazine
    • Time Frame: 24 weeks
    • To determine reduction in frequency of Angina with Ranolazine

Secondary Measures

  • Safety: Proportion of participants experiencing an adverse event (AE)
    • Time Frame: 24 weeks
    • Proportion of participants experiencing an adverse event (AE)

Participating in This Clinical Trial
