Is there anyone out there who has had an annurysm repair with a mechanical valve replacement who is on heart medications for life other than Coumadin? Can it be possible to only be on Coumadin?
Can it be possible to only be on Coumadin?
Hey Robert, I seem to be in a similar situation out of the chute as you. I had AVR on Jan 7, 2010 and was put on Amiodarone and Metoprol. I just quit the Amio which was to control early A-fib. Have to see how this works out! The other meds I take are 81mg aspirin, Crestor, and of course my Coumadin. I had some issues with the Amio early on but after a reduction in dose, everything was fine. I would definately be talking to my Cardio about continuing the Amio!!
Yes, I guess that makes sense. It is best to make just one change at a time.
I will have to look it up to be sure, but I thought I read that the Amio intensifies the action of Coumadin, and this reference http://www.umm.edu/altmed/articles/coenzyme-q10-000950.htm says COQ10 may decrease the effect of Coumadin. If I am analyzing correctly, let's say a 3mg dose of Coumadin/Warfarin is producing correct INR with Amio, going off Amio might normally require an upward dose adjustment of the anticoagulant. Addiing CO Q10 which would reduce effect could also require upward dose adjustment. Where it becomes really, really murky, is no one knows - per many articles I have read - exactly how long it takes for Amio to clear out of the body. One of the articles I put in says on the average 58 days, but some I have read put it at much longer than that.) This is an interesting abstract, http://jpp.sagepub.com/cgi/content/refs/20/6/469.
The Wikipedia link below contains reference "Unlike most other drugs, which are excreted via the urine, excretion is primarily hepatic and biliary with almost no elimination via the renal route and it is not dialyzable [Package Insert- Pacerone(R)]. Elimination half-life average of 58 days (ranging from 25-100 days [Remington: The Science and Practice of Pharmacy 21st edition]) for amiodarone and 36 days for the active metabolite, desethylamiodarone (DEA) ".
When I read this, http://en.wikipedia.org/wiki/Amiodarone "Amiodarone can worsen the cardiac arrhythmia brought on by Digitalis poisoning." that is why I was concerned about OP being on dig also. If Doctors are not monitoring his Digoxin level, which can build up in the body sometimes (likely to be the case since they do not seem to monitoring anything else! ), then Robert1562 could be in a 'pickle' as the saying goes, and nobody knows. His Doctors really are negligent, IMO.
Anyway, I only remember to take the CO Q10 sporadically, mostly on days that for some reason I am not eating much meat or any eggs (those being good dietary sources). I found something interesting on Amiodarone, that might especially be of interest to our original poster, http://www.aafp.org/afp/2003/1201/p2189.html. (It includes the statement "Laboratory studies to assess liver and thyroid function should be performed at least every six months.")
p.s. My Husband self-tests as he has A-Fib, but for some reason, his machine is too temperamental or needs larger sample; we have not been able to do a test calibration of his machine versus the one at clinic, so for now it is actually less trouble for me to go to the clinic for it.
