High haemoglobin values during medical treatment of hypertension.

In 123 patients with arterial hypertension the haemoglobin values were determined before and during long-term antihypertensive drug treatment. The haemoglobin values found before treatment did not differ from those found in the normal population. In both sexes the haemoglobin values showed a significant increase after prolonged treatment. In males the average values rose from 15.1 to 16.7 g./100 ml., and in females from 13.96 to 14.82 g./100 ml. The increase in the haemoglobin concentration does not seem to be clearly correlated to the duration of treatment or to the decrease produced in mean blood pressure. On the other hand, the increase in haemoglobin depended to some extent on the nature of treatment. Diuretics alone resulted in a moderate increase only, whereas diuretics in combination with other antihypertensive drugs produced a more pronounced increase in haemoglobin values.

Characterization of the thiazide-sensitive Na(+)-Cl(-) cotransporter: a new model for ions and diuretics interaction.

The thiazide-sensitive Na(+)-Cl(-) cotransporter (TSC) is the major pathway for salt reabsorption in the apical membrane of the mammalian distal convoluted tubule. When expressed in Xenopus laevis oocytes, rat TSC exhibits high affinity for both cotransported ions, with the Michaelis-Menten constant (K(m)) for Na(+) of 7.6 +/- 1.6 mM and for Cl(-) of 6.3 +/- 1.1 mM, and Hill coefficients for Na(+) and Cl(-) consistent with electroneutrality. The affinities of both Na(+) and Cl(-) were increased by increasing concentration of the counterion. The IC(50) values for thiazides were affected by both extracellular Na(+) and Cl(-). The higher the Na(+) or Cl(-) concentration, the lower the inhibitory effect of thiazides. Finally, rTSC function is affected by extracellular osmolarity. We propose a transport model featuring a random order of binding in which the binding of each ion facilitates the binding of the counterion. Both ion binding sites alter thiazide-mediated inhibition of transport, indicating that the thiazide-binding site is either shared or modified by both Na(+) and Cl(-).

Depression after treatment with thiazide diuretics for hypertension.

The authors reports eight cases of depression induced by thiazide diuretics prescribed for hypertension and discusses possible mechanisms behind this action. The side effects of thiazide diuretics may be overlooked when they are used with other hypertensives known to cause depression.

Experience with prazosin in a clinical setting.

In a three-phase study that began in 1969, prazosin was shown to be especially suitable for use in treatment of hypertensive patients with gout, renal disease, or borderline diabetes, owing to the sparing of organ systems often harmed by other antihypertensive drugs.

Long-term efficacy and safety of prazosin in essential hypertension.

The long-term efficacy and safety of prazosin plus a thiazide diuretic in severe hypertension has been evaluated in an open trial that is now in its fifth year. The combination is consistently effective in reducing diastolic blood pressure to 90 mm Hg or less. No side effects or adverse reactions have been observed except a "first-dose" fall in blood pressure, and there is no evidence of development of tolerance to the agent.
