Prostate drugs into the anus and prostate drugs through intravenous infusion, intramuscular injection and oral medication for the same reason. Because the rectal mucosa within the anus can also absorb the drug, the absorption of the drug into the blood circulation of the whole body to reach the prostate blood vessels, which can play a therapeutic role, is equivalent to the prostate disease to take the drug orally, into the body to absorb the same, and did not put directly into the prostate, urethra. Rather, it is taken orally through the gastrointestinal mucosa and absorbed into the bloodstream of the whole body, and then through the blood circulation into the blood circulation of the prostate gland to play a therapeutic role. The mucous membrane of the rectum and the gastrointestinal tract, like the mucous membrane, have the function of absorbing drugs, absorbing into the blood circulation and then play an anti-inflammatory and antibacterial effect. Therefore, the prostate drugs can be put into the rectum to play a therapeutic role. Moreover, after being put into the rectum, the dosage of the drug can be increased appropriately, and there will be no nausea, vomiting or gastrointestinal cramps and other side effects produced by oral intake.
