[The effectiveness of intravenous form of Nitro Mac in patients with acute left ventricular failure and functional class III angina].

Efficacy of intravenous drop Nitro Mac (alcoholic solution of nitroglycerin) in acute left ventricular failure and angina of functional class III was investigated in 18 patients aged 42-68 years. 1 ml Nitro Mac solution was diluted in 100 ml isotonic solution once a day (in severe condition twice a day) for 6 days. Nitro Mac relieved anginal attack on infusion minute 3-5 and anginal pain on minute 2. In angina functional class III Nitro Mac completely eliminated anginal attacks in 8 of 10 patients and reduced its number in 2 patients. Exercise tolerance has grown. Oral nitrates' doses could be decreased twice. Side effects were mild. Nitro Mac is recommended for treatment of acute cardiac failure and angina of functional class III as an effective medication.
