Enoximone, a new phosphodiesterase-inhibitor with positive inotropic and vasodilating activities is available for intravenous use in patients with severe heart failure. A review of the current knowledge regarding the adverse effects of this substance reveals that they are characterized by cardiovascular, central nervous, and gastrointestinal side effects. Adverse effects occurred in 20% of patients and were mostly due to the pharmacological properties of enoximone. Cardiovascular side effects (10%) were the most frequent; ventricular and supraventricular arrhythmias were most common. Two to three percent of the patients experienced hypotension due to the vasodilator activity of enoximone. Headache, insomnia, and anxiety were the most frequent adverse effects on the central nervous system. Three percent of the patients treated experienced vomiting, nausea, abdominal pain, and diarrhea. An increase of liver enzymes and serum glucose could be observed, mostly in patients with previous liver disease or diabetes. Pharmacokinetic drug interactions are not known; possible pharmacodynamic interactions result from the pharmacological properties of the drugs. Intravenous therapy with enoximone causes a few serious side effects that can only be controlled by careful observation of the patients treated.

Previous clinical studies with intravenous enoximone have used cumulative dosing to quantify enoximone's hemodynamic effects. The magnitude and duration of the hemodynamic effects of single intravenous doses of enoximone were evaluated in patients with congestive heart failure. Sixty patients, who were in New York Heart Association functional classes III and IV, received single intravenous doses of enoximone, either 0.25 (12 patients), 0.5 (13 patients), 1 (14 patients), 1.5 (10 patients) or 2 mg/kg (11 patients). Cardiac index was increased by 20% with the 0.25 mg/kg dose and by 48% and 42% with the 1.5 and 2 mg/kg doses, respectively. These increases were statistically significant (Student's paired t test with Bonferroni's correction, p less than 0.007) for 1 hour after 0.25 and 0.5 mg/kg, for 2 hours after 1 mg/kg and for 4 hours after 1.5 and 2 mg/kg. Enoximone also reduced pulmonary artery diastolic pressure by 19% with 0.25 mg/kg and by 29% with 2 mg/kg. The duration of effect varied from 1 hour with 0.25 mg/kg to 4 hours with 2 mg/kg. Enoximone produced no consistent or dose-related effects on heart rate or blood pressure. Eighteen adverse reactions were reported by 15 patients, of which 11 were minor and transient (vein pain, flushes, nausea). In 5 patients ventricular or supraventricular arrhythmias were observed, including nonsustained ventricular tachycardia and extrasystoles; 3 of these patients had evidence of arrhythmias before enoximone. Laboratory studies before and after treatment showed no drug-related effects. Dose-related effects on the magnitude and duration of hemodynamic responses to intravenous enoximone were evident within the dose range of 0.25 to 2 mg/kg.(ABSTRACT TRUNCATED AT 250 WORDS)
