Cardiovascular responses are reported in 21 patients with carcinoma of the bronchus taking part in a study of tumour perfusion. There were eight slow and 12 fast acetylators; acetylator status was not determined in one patient with a history of sulphonamide allergy. Hydralazine dose ranged from 25 to 150 mg orally (equivalent to 0.37 to 2.86 mg/kg). Mean arterial blood pressure fell from 98 mmHg before hydralazine to 90 mmHg 60 min after hydralazine (p = 0.002) and mean cardiac output rose from 5.53 l/min to 7.75 l/min (p = 0.00005). Calculated total peripheral resistance fell by 30% (p = 0.0002). Falls in peripheral resistance per milligram hydralazine administered were greater in patients over 70 years of age. Acetylator status was a poor predictor of response. Side-effects were reported by eight patients and were related to the magnitude of fall in peripheral resistance (p = 0.0005) but not to falls in blood pressure (p = 0.12).
