Interactions of anabolic steroids

Drug-drug interactions, or interference between drugs and other treatments, depend on many factors and are therefore difficult to predict. However, a number are clearly established in the case of anabolic-androgenic steroids. The beneficial interactions between anabolic steroids and radiotherapy or cytostatic drugs respectively are of therapeutic value. Adjuvant treatment with anabolic compounds in patients undergoing radiation and/or cytostatic therapy is beneficial because it can prevent or reduce depression of erythropoiesis, granulopoiesis and thrombopoiesis. It also diminishes protein catabolism, supports recovery, improves the general condition of the patient and minimizes radiation sickness. Potentially adverse interactions with anabolic steroids must be expected in the case of oral anticoagulants and antidiabetic drugs, since sensitivity to each of the latter is increased. This makes it particularly advisable to monitor patients receiving either oral anticoagulants or antidiabetic treatment concurrently with anabolic drugs.
