Terazosin in the treatment of hypertension and symptomatic benign prostatic hyperplasia: a primary care trial

The Journal of Family Practice
R Guthrie

Abstract

Terazosin, an alpha 1 blocker initially used as an antihypertensive, was approved in 1993 for use in the treatment of benign prostatic hyperplasia (BPH) symptoms. This study was designed to determine the safety and efficacy of terazosin in treating patients with concomitant BPH and hypertension. Middle-aged men with essential hypertension were enrolled by their primary care physicians in community practice. Those with symptoms of benign prostatic hyperplasia were identified by a Boyarsky scale score. The study was a 12-week, dose-escalation, open-label protocol for men aged 45 years and older. Enrollment in the study totaled 5365 patients. Of these, 1483 had Boyarsky scores of > or = 7, indicating symptomatic BPH. All patients with elevated blood pressure at the beginning of the study, including those with symptomatic BPH, showed significant reduction in blood pressure at the end of the 12-week trial. The patients with symptomatic BPH had statistically significant improvement in their BPH voiding symptoms. In the 1483 patients with BPH symptoms, terazosin produced a mean reduction of 55% in overall Boyarsky scores, 57% in obstructive symptom scores, and 54% in irritative symptom scores. In patients with baseline blood pressure ...Continue Reading

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
