Cyprodime is an opioid antagonist from the morphinan family of drugs.

Cyprodime is a selective opioid antagonist which blocks the μ-opioid receptor,^[1] but without affecting the δ-opioid or κ-opioid receptors. This makes it useful for scientific research as it allows the μ-opioid receptor to be selectively deactivated so that the actions of the δ and κ receptors can be studied separately, in contrast to better known opioid antagonists such as naloxone which block all three opioid receptor subtypes.^[2]
