[Effects of delayed-action metoprolol evaluated in hypertensive patients responsive to therapy subdivided in 2 different age groups].

Thirty patients with essential hypertension, whose blood pressure was controlled by metoprolol, were divided according to age in two groups. All the patients were treated with long-acting metoprolol given as simple daily dose at 08.00 h. Blood pressure and heart rate were recorded before and at the 7th, 15th, 30th, 45th, 60th days of treatment. No significant difference in the antihypertensive effects of metoprolol was detected between the two groups of patients. A significantly higher reduction of the heart rate was observed in the older patients.

Effects of inhaled fenoterol on the circadian rhythm of expiratory flow in allergic bronchial asthma.

Metered-dose aerosol treatment with fenoterol for three consecutive days, in eight patients suffering from allergic asthma, caused the disappearance of FEV1 and MEF50 circadian rhythm. We attribute such behavior to the suppression of the bronchomotor tone induced by fenoterol. The administration on different days of a single dose of fenoterol aerosol in another group of eight patients pointed out the variability of the effects of the drug at different hours of the day. We believe the results obtained are important for a better dosage and time distribution of the therapy with beta2 agonists.

Studies on the site of renal sodium loss in two patients with cystinosis. Effects of hydrochlorothiazide on tubular sodium reabsorptive mechanisms.

The purpose of this study was to examine the effect of hypotonic saline diuresis on two patients with cystinosis, trying to localize the site of renal sodium loss. At the same time, we have performed the same hypotonic saline infusion under hydrochlorothiazide administration. Results seem to prove the proximal tubular localization of the salt-wasting syndrome in cystinotic patients. On the other hand, these results suggest that hydrochlorothiazide effect can be related to the hypovolemia due to the distal tubular action of hydrochlorothiazide that could inhibit the 'third' natriuretic factor, thus increasing the proximal tubular sodium reabsorption.
