Finasteride 1mg is mainly known in the market under the brand name Propecia, which, for those who are concerned about hair loss in men or male pattern baldness, are very familiar with it. Finasteride 1mg is actually a drug that is indicated for treating benign prostatic hypertrophy and male pattern baldness. Finasteride 1mg is also sometimes used as a hormone replacement therapy for transsexuals (male to female) which is combined with some type of estrogen because of its anti-androgen characteristics.
Keep in mind that no matter how severe the case may be, finasteride 1mg is absolutely not approved for use in women, children and young adults. It is extremely not safe for women to take finasteride 1mg for their hair loss or baldness problems because it poses as a very dangerous drug especially if they are pregnant. Finasteride 1mg can cause serious birth defects in a developing baby, especially if it is a male one.
For those who are thinking of taking finasteride 1mg, you need to consider the following side effects that may happen to you: lowered levels of PSA (prostate specific antigen) which can conceal an increased level of PSA. Monitoring the level of PSA is mainly done as a clinical diagnostic test for detecting prostate cancer and sexual dysfunction; finasteride 1mg may increase your risk of prostate cancer if you already have had it in the past or you have it running through your genetic makeup; and lastly, finasteride 1mg may likely increase your chances of getting breast cancer and even make you experience some mood disorders like depression or anxiety.
Finasteride 1mg belongs to class of drugs known as 5 alpha reductase inhibitors, mainly the isoenzyme type II. Due to its action of inhibiting or stopping 5 alpha reductase, finasteride 1mg prevents the conversion process of testosterone into dihydrotestosterone (DHT) via the isoenzyme type II. This process results to a lowered level of serum DHT in the body by approximately 65% to 70% and DHT levels in the prostate by approximately 85% to 90%. Finasteride 1mg, because it does not contain the isoenzyme type I, which is actually much more potent than isoenzyme type II, it cannot completely suppress the production of DHT in the body.
By means of blocking DHT production in a man’s body, finasteride 1mg lowers the activity of androgen (the male hormone) in the scalp. Inside the prostate area, the blocking of 5 alpha reductase by finasteride 1mg lowers the prostate volume, which results to the improvement of benign prostatic hypertrophy and therefore lowers the development or risk of prostate cancer. However, you need to know that the inhibition of 5 alpha reductase can also decrease a man’s epididymal weight, and distorts the normal morphology and lowers the motility of spermatozoa inside the epididymis.
Keep in mind that DHT helps in activating a receptor known as GABAA, which tamps down the signaling process amongst neurons. Due to the fact that finasteride 1mg prevents the existence of DHT, it might lead to a lowered level of GABAA activity. A lowered GABAA in the body actually is implicated in cases of anxiety, depression, and even sexual dysfunction in men.
