Potassium-sparing diuretics are commonly used to help reduce the amount of water in the body. Unlike some other diuretics, these medicines do not cause your body to lose potassium.
Amiloride and spironolactone are also used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If the condition continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Spironolactone is also used to help increase the amount of potassium in the body when it is getting too low.
Potassium-sparing diuretics help to reduce the amount of water in the body by acting on the kidneys to increase the flow of urine. This also helps to lower blood pressure.
These medicines can also be used for other conditions as determined by your doctor.

It is a synthetic mixture. It is used as diuretic and against elevated blood pressure
It inhibits the union of the DHT and other hormones androgens, between which DHEA and the androstandiole (that it provokes the seborrea), with the receptors of the pilifer follicles. Topically is usually used at 1-5%.
It is one of the most powerful antiandrogen, more powerful to es. of the progesterone, of the ciproterone acetate and of the flutamide, in how much and it would prevent many androgens to unite with their receptors (studies in vitro). In fact it is not used in the men orally while it is being it of frequent in the women.
The topical spironolactone is one of the choices improves in the cases of female androgenetic alopecia : he must not be used in pregnancy and is necessary to use it after a careful analysis of the physician.
It is well absorbed from the skin and practically absorbed not systematically (from the rest of the body), therefore it is one of the best substances from to topical apply.
It is also used with progesterone. Have an odor a few
unpleasant of sulphur particularly if mixed together with the minoxidil.
It seems rational therefore the use of systemic finasteride that decreases the testosterone conversion in DHT and the topical use of spironolattone that it stops the remainder DHT to level of the follicles.
It is also possible to use the canreonato, molecule similar to the spironolattone but deprived of the group tiazoico, which doesn't have the problem of the odor.
According to Dr. Proctor, associating in solution the minoxidil with an antiandrogen as the spironolactone, the effectiveness of the minoxidil has increased of a lot
Spironolactone is a known antiandrogen (lowers or inhibits male hormones) which has been available for years. It probably the most commonly used oral antiandrogen in women for treating hair loss or excess facial hair. It is also frequently used by men to treat their hair loss. Many men buy a premixed spironolactone solution, or buy the tablets and add them to their minoxidil to improve results. Spironolactone works similarly to Propecia/Proscar, in that it inhibits the male hormone DHT. By adding 12 100mg spironolactone tablets to a 60mL 2% minoxidil bottle, you end up with roughly a 2% spironolactone, 2% minoxidil solution. Spironolactone can also be mixed with ethyl alcohol. We recommend refrigerating the combination to keep the solution fresh. If left at room temperature it may develop some odor but will still be effective.
Remox is a product that also contais spironolactone.
