Prenylamine (Segontin) is a calcium channel blocker of the amphetamine chemical class which is used as a vasodilator in the treatment of angina pectoris. It has been shown to partially metabolize to amphetamine and can cause false positives for it in drug tests.[1][2][3] Prenylamine also appears to act as a vesicular monoamine transporter inhibitor, and has been demonstrated to deplete vesicular monoamine neurotransmitter stores similarly to reserpine.[4]
