WebMechanism of Action. GTN is a prodrug which must first be denitrated to produce the active metabolite nitric oxide (NO). Nitrates which undergo denitration within the body to produce NO are called nitrovasodilators and their denitration occurs via a variety of mechanisms. The mechanism by which nitrates produce NO is widely disputed. WebGTN skin patches or ointment are used every day to help prevent chest pain starting.
