CHLORTHALIDONE ALONE OR IN FIXED COMBINATION WITH SLOW-RELEASE METOPROLOL IN THE MANAGEMENT OF ARTERIAL-HYPERTENSION - A LONG-TERM STUDY OF 545 PATIENTS

In a double-blind trial, 545 out-patients with essential hypertension received 25 mg/day chlorthalidone alone (274 patients) or in fixed combination with 200 mg/day slow-release metoprolol (271 patients) for 8 weeks. Both treatments signficantly (P < 0.001) decreased systolic and diastolic blood pressure; 45.6% of patients receiving chlorthalidone and 82.5% receiving combined therapy had a diastolic blood pressure of less than 95 mmHg. Patients not controlled by chlorthalidone or chlorthalidone plus metoprolol subsequently received chlorthalidone plus metoprolol (137 patients) or chlorthalidone plus metoprolol plus a third drug (34 patients), respectively, for 8 weeks. A total of 79.5% of patients receiving chlorthalidone plus metoprolol and 61.8% receiving chlorthalidone plus metoprolol plus a third drug had a diastolic blood pressure of less than 95 mmHg. Only 5.9% of patients experienced mild to moderate side-effects. Plasma potassium levels significantly (P < 0.01) decreased during the first 8 weeks only. It is concluded that a diuretic alone or in fixed combination with a \u3b2-blocker is effective in the long-term treatment of arterial hypertension

High-dose loperamide in the treatment of 5-fluorouracil-induced diarrhea in colorectal cancer patients.

Thirty-seven colorectal cancer patients with grade 1-4 diarrhea (NCICTC) caused by chemotherapy with 5-FU-containing regimens, received oral loperamide at the initial dose of 4 mg followed by 4 mg every 8 h (total dose 16 mg/24 h). Twenty-five patients (69\%) were diarrhea-free and were considered to be treatment responders. Eight-four percent of the patients with grade 1 or 2 diarrhea achieved a response, but only 52\% of those with grade 3-4 diarrhea. These data seem to suggest that high-dose loperamide is effective in patients with moderate diarrhea and can be regarded as the treatment of choice. The patients with more severe diarrhea did not respond so well, and should, perhaps, be given first-line treatment with more effective drugs, such as somatostatin analogues (e.g., octreotide)
