Long-acting resorbable subcutaneous implant with extended release of pre-concentrated pharmacologically active substance in polymer for treatment of chronic adrenal insufficiency. The implant is inserted subcutaneously and has continuous release of the active ingredient for an extended period of time. The implant may have in its constitution only hydrocortisone but is preferably formed by hydrocortisone particles homogeneously dispersed in a bio erodible and bioabsorbable polymer matrix. Such a polymer matrix may be formed of a polymer or a polymer blend. The release of the drug in this system occurs through diffusion, at a relatively constant rate, and it is possible to change the rate of release of the drug through the thickness or material of this membrane.
