Long-term treatment with slow-release frusemide compared with thiazide treatment in arterial hypertension

The Journal of International Medical Research
H JørgensenL E Peterson


The effect of 30 mg/day slow-release frusemide given orally for 12 months was studied in 64 patients previously treated with thiazides for mild to moderate essential hypertension. Frusemide had a significant antihypertensive effect (P less than 0.001), and compared to thiazides significantly reduced fasting serum glucose (P less than 0.015), haemoglobin A1c (P less than 0.025), albumin (P less than 0.025) and serum calcium (P less than 0.025), and significantly increased serum sodium and chloride concentrations (P less than 0.0001). There was also a non-significant trend for frusemide to reduce serum total cholesterol, triglycerides and urate, and to increase serum potassium. Frusemide was well tolerated in all but three patients. It is concluded that slow-release frusemide has a comparable antihypertensive effect to that of thiazide diuretics, but has fewer metabolic side-effects, and should be used in-preference to thiazides for the treatment of arterial hypertension when a diuretic is indicated.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
