The antihypertensive effect of once and twice daily hydrochlorothiazide administration was compared in 24 ambulatory patients with essential hypertension. Hydrochlorothiazide 100 mg daily taken as a single morning dose or as a twice daily divided dose was administered to 24 previously diagnosed hypertensive patients in a double-blind cross-over fashion for 12 weeks. No patient received other antihypertensive agents or medications known to influence blood pressure. Sitting and standing blood pressure, weight, pulse, tablet count, and subjective complaints of side effects were obtained at study weeks 3 and 6 on each treatment schedule. There was no significant difference between the mean sitting systolic (133 and 131 mm Hg) or diastolic (85 and 84 mm Hg) blood pressure measurements at study weeks 3 and 6 for each treatment schedule. Comparison of standing mean systolic and diastolic blood pressure and mean arterial pressure produced similar results. Subjective complaints of medication side effects, including orthostasis or urinary frequency, did not differ between treatment schedules. This study suggests that hydrochlorothiazide may be effectively administered once daily for the treatment of hypertension.

Tiodazosin, a new antihypertensive, resembles prazosin in structure and alpha-adrenergic-blocking activity, and it also exerts a direct vasodilator effect. We evaluated its long-term hemodynamic and systemic effects in patients with essential hypertension. Our data show that after 10 wk of therapy with tiodazosin, 7 of our 10 patients had significant reduction in intra-arterial mean blood pressure as a result of a fall in systemic vascular resistance. Heart rate, cardiac output, and plasma volume did not change. Systemic effects were minor and included a gain in weight and a reduction in hemoglobin, hematocrit, platelet count, serum protein, albumin, bilirubin, and specific gravity of urine. No patient initially developed orthostatic symptoms after the first dose, but there were transient episodes of light-headedness in three patients, palpitations in two, increased urinary frequency in one, and drooping of eyelid in another during the trial period. One patient developed profound orthostatic hypotension, which could be attributed to the drug. Because of such side effects and the failure to lower blood pressure in 30% of patients with essential hypertension, tiodazosin appears to have several important drawbacks and little advantage over currently available antihypertensives.

A 70-year old woman was admitted with an acute nontraumatic paraparesis. She enjoyed complete independence in all activities of daily living, although she had essential hypertension, dyslipidemia, mild depression and urinary frequency. In the past, the patient underwent a total right knee replacement and removal of right eye cataract. Neurological and radiological investigations excluded any cause for spinal cord compression. Enlarged thyroid gland which was seen on cervical MR scanning was left unnoticed. The diagnosis was made: a spinal stroke. After admission to the rehabilitation ward, full thyroid gland function investigations were conducted. Lower limbs weakness totally subsided when therapy was provided.
