Chronic bacterial prostatitis is a common disease in men’s medicine, accounting for approximately 5% of patients with chronic prostatitis. The difficulty in its treatment is that many antibacterial drugs do not penetrate the prostate lipid membrane, an anatomical barrier that affects drug absorption. This is a very good way to get the most out of your life. The local administration of drugs via perineal prostate injection bypasses the anatomical barrier of the prostate lipid membrane that affects drug absorption. It has been shown that direct injection into the prostate can maintain the non-degradable active form of the drug at concentrations much higher than MIC90, and that there is a traffic link between the left and right side lobes of the prostate, which allows unilateral injection to diffuse the drug into the prostate tissue on the other side. The main components of Chuanshantong injection are Danshen, Rhizoma Ligusticum Chuanxiong, Madonnas and Angelica Sinensis, which have the effects of activating blood stasis, anti-inflammation, decongesting edema, improving microcirculation and promoting the repair of diseased tissues. In vitro tests have found that it has significant anti-inflammatory effects and is resistant to a variety of bacteria such as Escherichia coli and Proteus mirabilis. Chuanshantong can be mixed with various antibiotics to form compound Chuanshantong, which will greatly improve the antibacterial effect of antibiotics. For example, the antibacterial activity and antibacterial efficacy can be significantly improved by combining with cephalosporin sodium, cefazolin sodium, cefradine, cefotaxime and cefuroxime. Chuanshantong injection with its unique drug delivery method plus local prostate injection of drugs such as bacteriophage, overcomes the defects of poor absorption, weak efficacy, long course of treatment, easy recurrence after discontinuation of drugs and multiple complications after injection, and has significant clinical efficacy.
