Question: I am a male aged 57. About two and half years back, I was diagnised with Two Vessel disease. The angio gram revealed 100% occulsion of RCA and about 70% of LAD. The cardiologist advised that nothing much could be done to RCA, but LAD can be saved and over the years, collateral circulation might come about. I underwent angioplasty with two drug eluting stents. Since then, I have been taking Betaloc 25; olmestat 20 before breakfast. I take one Pan 40 also before breakfast. After breakfast, I take nitrocontin 2.6, one tablet, Flavedon MR 35 one; cordarone 25 (only during the last three months) and Becadexamin. At noon I take one omacar and one Tayo. At night, I take one nitrocontin 2.6; one flavedon MR35; one combiplet 150 and one Aztor EZ 20. My Blood Test, cholestrol , HDL/LDL are within normal limits. I have no sugar complaint. I go for walk, do Pranayam and continue working, though the work is stressful. The various web sites state that when one takes nitrates, sidenafil should not be taken and is XXXXXXX My cardiologist, when I asked casually ( I was hesitant to ask), stated that half a tablet once in a while should not be an issue. My question is can I stop nitrocontin, say 24 hours before taking sidenafil 20 mg, since Iam taking combiplet and other medicines.
