4.2 Drug Warning

Use of anabolic steroids by athletes is not recommended. Objective evidence is conflicting and inconclusive as to whether these medications significantly increase athletic performance by increasing muscle strength. Weight gains reported by athletes are due in part to fluid retention, which is a potentially hazardous side effect of anabolic steroid therapy. The risk of other unwanted effects, such as testicular atrophy and suppression of spermatogenesis in males; menstrual disturbances and virilization, such as deepening of voice, development of acne, and unnatural growth of body hair in females; peliosis hepatis or other hepatotoxicity; and hepatic cancer outweigh and possible benefit received from anabolic steroids and make their use in athletes inappropriate. /Anabolic steroids/

Anabolic agents may accelerate epiphyseal maturation more rapidly than linear growth in children, and the effect may continue for 6 months after the drug has been stopped. Therefore, monitor therapy by x-ray studies at 6 month intervals to avoid the risk of compromising adult height. Safety and efficacy in children with hereditary angioedema or metastatic breast cancer (rarely found) have not be established. /Anabolic steroids/

Anabolic Agents

These compounds stimulate anabolism and inhibit catabolism. They stimulate the development of muscle mass, strength, and power. (See all compounds classified as Anabolic Agents.)


Androgens

Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.

5.4 Absorption, Distribution and Excretion

Metabolic studies of (14)c-labe nortestosterone were carried out in mice and in calves. Radioactivity was quickly eliminated mainly in urine and feces. 10 wk after admin residual levels were low. Rapid absorption and elimination may be important in vet use.

5.6 Mechanism of Action

Functionally overloading rat soleus muscle by synergist ablation induces a rapid increase in mass. Muscle remodeling during the first week of overload is critical for the overload-induced growth. Anabolic steroid modulation of this overload-induced remodeling response is not well understood. The purpose of this study was to determine whether pretreatment with nandrolone decanoate, a clinically administered anabolic steroid, alters muscle morphology and gene expression related to muscle growth during the initiation of functional overload in the rat soleus muscle. Adult (5 mo) male Fisher 344 x Brown Norway rats were randomly assigned to control (Sham), 3-day functional overload (OV), nandrolone decanoate administration (ND), or 3-day functional overload with nandrolone decanoate administration (OV+ND) treatment groups. Morphologically, OV increased the percentage of small (361%) and large (150%) fibers and expanded the ECM 50%. ND administration decreased the 3-day OV induction of small fibers 51% and nuclei associated with the ECM 20%. ND administration also attenuated the induction of cell cycle regulator p21 (64%) and myogenin (37%) mRNAs after 3 days of overload. These data demonstrate that nandrolone decanoate pretreatment can alter morphological and cell cycle regulator expression related to muscle growth at the onset of functional overload.

Anabolic-androgenic steroids (AASs) are widely abused by adolescents, although persistent AAS use can cause several adverse physical and mental effects, including drug dependence. The first aim of the present study was to study the action of nandrolone decanoate on dopaminergic and serotonergic activities in the brains of rats. In order to evaluate the anabolic or toxic effects of the dosing regimens used, selected peripheral effects were monitored as well. Male Wistar rats were treated for 2 weeks. Injections containing nandrolone (5 and 20 mg/kg, i.m.) or vehicle were given once daily, 5 days a week. The levels of dopamine (DA), 5-hydroxytryptamine (5-HT) and their metabolites were assayed from dissected brain regions 3 days after the last injection. Blood was collected for chemical assays before, after 1 week treatment and at decapitation. Both doses of nandrolone significantly increased the levels of 3,4-dihydroxyphenylacetic acid (DOPAC), a metabolite of DA in the cerebral cortex, and the higher dose of nandrolone increased the concentrations of 5-HT in the cerebral cortex compared with the vehicle. In addition, after nandrolone treatment, the levels of hemoglobin and erythrocytes increased, and reticulocyte levels decreased. The results suggest that nandrolone at supraphysiological doses, high enough to induce erythropoiesis, induces changes in the dopaminergic and serotonergic neuronal system in the brains of rats. These phenomena may account to some of the observed central stimulatory properties that have been reported following AAS abuse.
