Comparison of guanfacine versus clonidine for efficacy, safety and occurrence of withdrawal syndrome in step-2 treatment of mild to moderate essential hypertension.

Guanfacine, an alpha 2-adrenoceptor agonist, was compared with clonidine as step-2 therapy of mild to moderate essential hypertension in a 24-week, double-blind, randomized, parallel evaluation to determine efficacy, safety and occurrence of withdrawal syndrome. During a 5-week period, patients were weaned from current antihypertensives, if any, and stabilized on step-1 therapy with 25 mg of chlorthalidone once a day. Those with a diastolic blood pressure (BP) from 95 to 114 mm Hg while taking chlorthalidone were randomized to treatment.

Psychotropic drug use in family practice.

In an attempt to assess the precision of an illness-treatment "fit" between dispensing and actual need for psychotropic medications, the present study examined the dispensing patterns to consecutive attenders of private general practice. "Conservative" use of psychotropic drugs was indicated insofar as patients were seldom dispensed medication in the absence of emotional problems, and the presence of emotional problems frequently was not accompanied by the dispensing of medication. In addition, specific social and illness factors were located which could differentially predict either the presence of emotional problems, the use of psychotropic drugs, or both of these variables.
