    In healthy males, testosterone is produced primarily by the testes and in small amounts by the adrenal glands. Most of the testosterone is transported bound to a specific plasma protein called sex hormone binding globulin (SHBG). This protein is produced in the liver and carries the sex hormones (androgens in males and estrogens in females) to their site of action in the body. The testosterone that does not bind to SHBG is termed free testosterone and it is this testosterone that can be converted to dihydrotestosterone (DHT) by the enzyme 5-alpha reductase. Both DHT and testosterone can bind to the androgen receptor but DHT binds with a greater affinity than unbound or unchanged testosterone. Once bound to the androgen receptor, DHT or testosterone forms a complex that undergoes a structural change. This complex then moves into the nucleus of the cell and binds to specific nucleotide sequences of DNA called hormone response elements. Finasteride is used to shrink an enlarged prostate (benign prostatic hyperplasia or BPH) in adult men. It may be used alone or taken in combination with other medications to reduce symptoms of BPH and may also reduce the need for surgery. Finasteride may improve symptoms of BPH and provide benefits such as decreased urge to urinate, better urine flow with less straining, less of a feeling that the bladder is not completely emptied, and decreased nighttime urination. This medication works by decreasing the amount of a natural body hormone (DHT) that causes growth of the prostate. Finasteride is not approved for prevention of prostate cancer. Read the Patient Information Leaflet provided by your pharmacist before you start taking finasteride and each time you get a refill. It may slightly increase the risk of developing a very serious form of prostate cancer. If you have any questions regarding the information, consult your doctor or pharmacist. Take this medication by mouth, with or without food, usually once a day, or as directed by your doctor.

    This week’s article in my continuing series on depression and antidepressants will examine the physiological, psychological and social consequences of antidepressant use. Although these drugs are generally considered to be safe by the media and amongst medical professionals and patients, a close look at the evidence suggests otherwise. Antidepressants have serious and potentially fatal adverse effects, cause potentially permanent brain damage, increase the risk of suicide and violent behavior in both children and adults, and increase the frequency and chronicity of depression. Chronic use of antidepressants also promotes dependency on drugs rather than empowering people to make positive life changes, and places a tremendous burden on healthcare systems in the U. and abroad – but I will discuss those issues in next week’s article. The adverse effects of antidepressants include movement disorders, agitation, sexual dysfunction, improper bone development, improper brain development, gastrointestinal bleeding, and a variety of other lesser known problems. These are not rare events, but the most significant harm comes only after months or years of use, which leads to the false impression that antidepressants seem quite safe. More than half of those beginning an antidepressant have one of the more common side effects (Brambilla et al. While some side effects may not carry serious health risks, others do.
