The haemodynamic effects of nefopam (0.3 mg/kg i.v.) were measured for 45 minutes in ten patients with coronary heart disease. The drug is a new and highly potent analgesic without any respiratory depressant effect. Arterial blood pressure and cardiac output rose moderately, while left ventricular enddiastolic pressure remained unchanged. Heart rate did not exceed 91/min. Max dp/dt, min dp/dt, Vpm and V40 rose by a maximum of 16% above control. Thus nefopam differs from other potent analgesics in having a slight inotropic effect.
