how painkilers work
When a cell is hurt or damaged it release a chemical that lowers the nociceptors sometimes to the point where even touch can hurt then that this is chronic pain when painkillers come in.”Aspirin and Ibuprofen block the making of prostaglandins.When cells are damaged they release a chemical called arachidonic acid 2 emzins called cox 1 and cox 2 convert the arachidonic acid to prostaglandin h2 then it turns other chemicals to other thing.Aspirin puts something in the enzymes stopping the arachidonic acid from being changed this permanently deactivating cox 1 and cox 2.Ibuprofen actually put their self in and cox 1 and cox 2 are free to take them out but while Ibuprofen is there it stops arachidonic acid
