Ventricular Tachycardia - I've been dealing with episodes of VT for six months. I've had two EP studies done with one ablation. I was on toprol xl and my doctor switched me to toprol succinate. It seems like my PVCs are more noticeable with the switch. Does anyone know the difference between these two drugs?
I was on toprol tartrate and switched to toprol xl succinate, whats the difference?

I should clarify that I was on toprol tartrate and switched to toprol xl succinate. I was wondering what the differences are and which one do most people consider most effective. It seems like my pvcs are more noticeable on the toprol xl.
They both contain the same drug - Metoprolol so have the same effect. The only real difference is that one is an extended release tablet and the other is an immediate release tablet. This can affect control.
The XL succinate is an extended release tablet . This means a small and even amount of drug reaches your blood constantly. You normally take this tablet once a day.
The tartrate drug is an immediate release tablet and drug levels peak after a certain time and then decline. This usually requires you to have to dose more than once a day (but not always).
I would talk with your doctor if you preferred the toprol tartate immediate release tablet.
