SUMMARY1. Cyclosporin A (CyA; 12 mg/kg/day) was infused into six conscious sheep over 5 days to examine the haemodynamic effects of the drug in normal animals.2. Mean arterial pressure was increased from 73(1) mmHg to 90(4) mmHg (P 〈 0.001). There was no change in cardiac output but calculated total peripheral resistance was elevated from 16(1) to 21(2) mmHg min/1 (P 〈 0.001) on day 4.3. There was no change in plasma [Na], but a fall in plasma [K]. Urinary Na excretion decreased. Glomerular filtration rate, filtration fraction, renal blood flow, renal vascular resistance, body weight, plasma renin and blood aldosterone concentration were unchanged.4. CyA produces an increase in blood pressure in sheep associated with an increase in total peripheral resistance on days 1, 3, and 4, in the absence of changes in renal function. This suggests that CyA hypertension is not simply a consequence of nephrotoxicity.
