The effects of Ro 12-4713, a vasodilator, on blood pressure and heart rate, were tested in 13 ambulant patients with mild to severe hypertension. The patients received Ro 12-4713 in total oral doses ranging from 1.5 to 4 mg/kg over a 3-5 day period. Standard laboratory tests were done 24 h before and after the study. Standing and supine blood pressure and heart rate were determined before, and every hour for 6-8 h after drug administration. ECGs were recorded before, during and at the end of each study day. Ro 12-4713 reduced the pretreatment standing and supine-blood pressure from 213 +/- 34/126 +/- 21 mmHg and 218 +/- 31/130 +/- 20 mmHg to 156 +/- 33/85 +/- 9 mmHg and 158 +/- 25/88 +/- 11 mmHg at the end of Day 5. Heart rate was only transiently increased in patients with pretreatment values of less than 90 beats/min. Although abnormal ECGs tended towards normalization, there were 2 cases of T-wave inversion (the patients remained asymptomatic). Raised BUN levels tended to decrease towards normal. Side effects reported spontaneously by patients (headaches, palpitations, dizziness, nausea and one case of water retention) appeared to be transient in nature. Ro 12-4713 appeared to be a very potent and long lasting antihypertensive agent, whose inherent side effects were only transient in nature.
