Magnesium   is a powerful anti-arrhythmic drug . It has a well  established role in controlling VT when administered  Intravenously   especially in polymorphic VT .

Mechanism of action

  • It acts at the cell membrane.
  • It has a unique action of blocking calcium channels  that reduces the number of oscillations of  both  early and late  after potentials

How often cardiologists administer oral magnesium for long-term control of VT ?

As for as I know ,  no one uses it ! but dietary  supplements are used for general well  being .

Why ? Is it because

  1. Magnesium does not get absorbed in the gut
  2. Magnesium levels are un- predictable in plasma if administered orally

Answer : No one has really tried  it as a  chronic therapy in VT  yet  !

Final Message

Tablet Magnesium can give a tough fight to Amiodarone and Flecanaide in refractory VT at a fraction of the cost !

Who has the audacity  to  compare Magnesium  with Amiodarone head on ?

Reference

Magnesium as health supplement . 

Magnesium is available  in tablet form as  Malate , Stearate, Taurate and Aspartate  along with calcium and Zinc etc .
