Effects of natural oestrogen therapy on blood pressure and renin-angiotensin system in normotensive and hypertensive menopausal women.

The blood pressure level and the renin-angiotensin system were investigated in 24 menopausal women (12 normotensive and 12 hypertensive) before, during and after six months of treatment with either oestradiol or trisekvens (sequential preparation containing oestradiol, oestriol and norethisterone acetate). In the normotensive women no significant alterations in systolic or diastolic blood pressure were found during treatment for six months. In the hypertensive women systolic blood pressure fell significantly during treatment with oestradiol as well as with trisekvens, while diastolic pressure did not change. All individual variations of blood pressure were small. The plasma concentrations of renin, angiotensin II and aldosterone remained unchanged during the treatments. A statistically significant increase in plasma renin substrate concentration was observed in all groups with the exception of the normotensive women treated with oestradiol. Menopausal symptoms in hypertensive women may safely be treated with natural oestrogens on the same indications as used for normotensive women.

Effect of acetylsalicylic acid on renal function in systemic lupus erythematosus.

Glomerular filtration rate (GFR; 51Cr-EDTA clearance), serum creatinine concentration and urinary excretion of prostaglandins were measured in 8 patients with systemic lupus erythematosus (SLE) before and after 2 weeks of treatment with acetylsalicylic acid (ASA). ASA 65 mg/kg or up to 4 g/daily was given as a sustained release preparation. The serum salicylate concentration ranged from 0.3 to 1.6 mmol/l. Serum creatinine after 1 and 2 weeks and GFR after 2 weeks of ASA treatment showed no significant changes. There was a clearcut decrease in urinary excretion of prostaglandins PGE2 and PGF2 alpha, by 44% and 50%, respectively. It is concluded that therapeutic doses of ASA do not cause deterioration of GFR in patients with SLE and normal or moderately reduced renal function.

Immediate central and peripheral haemodynamic effects of a new vasodilating agent Pinacidil (P1134) in hypertensive man.

The purpose of this study was to evaluate the immediate central and peripheral haemodynamic effects of a new vasodilating agent P 1134, in hypertensive man. After oral administration of 25 mg P 1134, the maximal haemodynamic changes were (mean +/- 1 SEM): mean blood pressure fell from 121.8 +/- 6.5 to 80.5 +/- 7.8 mmHg, heart rate increased 24.2 +/- 4.5 beats/min, cardiac output rose 2.9 +/- 0.3 1/min and forearm blood flow increased 1.0 +/- 0.1 ml/100 ml tissue/min. Stroke volume increased 17.0 +/- 2.1 ml and the inotropic state of the heart as judged from systolic time intervals increased. Total peripheral resistance and forearm vascular resistance were both reduced by approx. 50%. Linear correlations were found between the serum concentration of P 1134 and the change in mean blood pressure and total peripheral resistance. Changes in the other parameters mentioned above occurred progressively with changes in mean blood pressure and total peripheral resistance. It can be concluded that P 1134 is a very potent hypotensive agent with a haemodynamic profile identical to that seen with vasodilators with preferably act on precapillary resistance vessels. Potency and maximal efficacy exceeds that of hydralazine and seems like that of minoxidil. P 1134 is remarkably free from side-effects apart from causing water retention as all other vasodilators. It can be administered orally as well as intravenously. This makes P 1134 a very interesting compound in the treatment of moderate to severe hypertension, and further studies are well-founded.
