Summary

"This trial aims to investigate how blood vessels widen in response to low oxygen levels and the involvement of specific receptors in women of different age groups: younger, middle-aged, and older women."

Who is the study for?
This trial is for women assigned female at birth who are premenopausal, perimenopausal, or postmenopausal. Participants should have a healthy weight with a BMI between 18 and 30 kg/m2. The study aims to understand how aging and menopause affect blood vessel responses during low oxygen conditions.
What is being tested?
The study is testing the effects of Propranolol (a beta-blocker), Gemtesa (used for overactive bladder), and a placebo on blood vessel dilation in hypoxic conditions among different stages of menopause. It's designed to see if these drugs influence the body's response to low oxygen.
What are the potential side effects?
Propranolol may cause dizziness, fatigue, or cold hands/feet. Gemtesa can lead to dry mouth, constipation, or blurred vision. Placebos typically have no active ingredients but can sometimes cause side effects due to psychological factors.
