The present application pertains to the medical sector and comprises a biodegradable implant containing tadalafil in a polymer matrix. Said implant is inserted into the subcutaneous layer of the patient and provides continuous release of the pharmaceutical active substance for a sustained period of time, achieving a drug serum level that is effective in the treatment of erectile dysfunction and benign prostatic hyperplasia. The implant is made up of tadalafil particles uniformly dispersed in a biocompatible, biodegradable polymer matrix. In addition, the implant can contain a polymer coating wall and the duration of the treatment can therefore vary between three and six months, thus setting the proposed period of time between insertions of new implants.
