Administration of gallopamil by long-term venous infusion in spontaneous angina. A single-blind, self-controlled study versus placebo.

In order to assess the efficacy and tolerability of gallopamil (D-600, CAS 16662-47-8) by long-term venous infusion in the treatment of spontaneous angina, 15 consecutive patients were studied in a single-blind, self-controlled trial versus placebo. Following a 24-h Holter ECG recording of the patients receiving a saline infusion (run-in phase), i.v. administration of gallopamil was started at a dose of 0.02 mg/kg/h preceded by a 0.03 mg/kg bolus. After 24 h, the dosage was increased to 0.03 mg/kg/h and the infusion was maintained for another 48 h. The Holter ECG recording was repeated in the last 24 h of treatment and after 6 h from withdrawal (washout phase). The reduction in the number of angina attacks, as shown by a comparison between the average of the two placebo periods (run-in and washout phases) and the three days of treatment, was 68.2%, 92.5%, and 87%, respectively. Consumption of glyceryl trinitrate decreased by 92.5% on each one of the three days of treatment. The reduction in the number of ischemic episodes (IEs) with symptomatic (-91.6%) and silent (-98.0%) ST elevation, and with symptomatic (-100%) and silent (-90%) ST depression, also proved significant. Heart rate decreased only moderately. One patient showed a mild first-degree heart block, while another suffered a transient episode of isorhythmic A-V dissociation. In conclusion, when administered by venous infusion, gallopamil has been found to be well tolerated and highly effective in the treatment of spontaneous angina.(ABSTRACT TRUNCATED AT 250 WORDS)

[Gallopamil infusion for treatment of Prinzmetal angina].

The efficacy of a new calcium channel blocker, gallopamil, has been tested via a single blind, self-controlled versus placebo protocol in 9 consecutive patients admitted to our Coronary Care Unit because of repeated daily attacks of Prinzmetal variant angina. Exclusion criteria were age (greater than 65 years) bradycardia (less than 50 beats/min), recent myocardial infarction, heart failure, sinoatrial or atrioventricular block. After a 24 hours run-in period on saline drip, gallopamil was administered as 0.03 mg/kg bolus followed by continuous infusion at 0.02 mg/kg/h for the first 24 hours and 0.03 mg/kg/h for the last 48 hours. Treatment was then stopped and the patients were again kept on saline infusion for the next 30 hours. Holter monitoring was recorded during run-in, on third day of treatment and 6 hours after gallopamil withdrawal. Anginal attacks were significantly reduced in number by therapy (-63%, -91%, -84% in the 3 days of treatment). Holter monitoring during gallopamil infusion showed a statistically significant reduction in silent (-98%) and symptomatic (-93%) ischemic episodes (IE). During the last 24 hours of the washout period we observed a statistically significant increase in silent ischemic episodes. While no transient ST segment elevation was recorded in 3 patients, in 1 patient symptomatic IE were increased of 150% with respect to the run-in period. On the whole we observed complete suppression of IE in 7 patients (78%) at the third day of treatment with gallopamil. In 2 patients (22%) a greater than 75% reduction was observed.(ABSTRACT TRUNCATED AT 250 WORDS)

[Verapamil in effort angina: a multi-centre study].

We have performed a multi-centre study with 47 outpatients in order to evaluate the efficacy of Verapamil (V) in the treatment of stable effort angina, and to compare the effect of two different doses of the drug (240 and 360 mg/die). The protocol consisted of a first period of Placebo, followed by the double-blind randomized cross-over administration of Placebo (P) and Verapamil (V) in doses of 240 and 360 mg/die. The symptomatology, the consumption of TNG, the ECG pattern at rest and during exercise, the maximum exercise tolerance during exercise and the rate of recovery were evaluated at the end of each 1 month period. V. provided a significant reduction of the number of angina attacks and of the consumption of TNG pills with improvement of symptomatology. The maximum exercise performance improved without changes in maximum rate pressure double product. A decrease of double product was observed at rest and during the recovery period. The higher dose of V. (360 mg/die) provides a better improvement in the number of angina attacks, in the symptomatology, in the double product at rest, and in the rate of recovery than the lower dose (240 mg/die). Thus these data indicate that V. provides anti-anginal efficacy by reducing myocardial oxygen demand, and increases exercise tolerance in effort angina patients.
