what are isopores?

Question

I was prescribed GTN by my doctor for angina pain. the first time i used it , it seemed to mak me worse and start to vomit. My GP says that if the pain is too bad again to go straight to hospital but i read somewhere thatisopores are sometimes used insted of GTN. Does anyone know what they are?

Like Colin I have searched many sources and the only thing I can find for isopores does not relate at all to heart medication;
