The present invention is directed to a powdered formulation comprising an analgesic, preferably fentanyl, for use in pulmonary inhalation administration for the rapid analgesic titration of pain, in particular breakthrough pain. Upon administration, the powdered formulation is able to provide a narrower titration range in patients suffering from pain, as well as effective analgesic amounts of fentanyl in a shorter time and at lower dose levels of administered fentanyl when compared to fentanyl administered by an oral transmucosal route.
