Until recently, almost all vocational education took place in the classroom, or on the job site, with students learning trade skills and trade theory from accredited professors or established professionals.
Spironolactone (Aldactone) may be used with other medicines to treat high blood pressure and heart failure. It may also help people who have too much aldosterone, a hormone, or people who have edema (fluid retention) from heart, liver, or kidney disease. Certain antidepressants may lower testosterone levels.
For men, normal testosterone levels range from 300 to 1,000 ng/dl. The FDA requires that any new drug used in hormone therapy for prostate cancer lower testosterone levels to 50 ng/dl or less. In my practice, I usually try to lower levels even further, to 20 ng/dl.
