  • Oxandrin (Oxandrolone Tablets, USP) DESCRIPTION Oxandrin Oral Tablets Contain Either 2.5Mg Or 10Mg of the Anabolic Steroid Oxandrolone
    BTG PHARMACEUTICALS Oxandrin (oxandrolone tablets, USP) DESCRIPTION Oxandrin oral tablets contain either 2.5mg or 10mg of the anabolic steroid oxandrolone. Oxandrolone is 17B-hydroxy-17a-methyl-2- oxa-5a-androstan-3-one with the following structural formula. Inactive ingredients include cornstarch, lactose, magnesium stearate, and hydroxypropyl methyl-cellulose. CLINICAL PHARMACOLOGY Anabolic steroids are synthetic derivatives of testosterone. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drug. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testes. During exogenous administration of anabolic androgens, endogenous testosterone release is inhibited through inhibition of pituitary luteinizing hormore (LH). At large doses, spermatogenesis may be suppressed through feedback inhibition of pituitary follicle-stimulating hormone(FSH). Anabolic steroids have been reported to increase low-density lipoproteins and decrease high-density lipoproteins. These levels revert to normal on discontinuation of treatment. INDICATIONS AND USAGE Oxandrin is indicated as adjunctive therapy to promote weight gain after weight loss following extensive surgery, chronic infections, or severe trauma and in some patients who without definite pathophysiologic reasons fail to gain or to maintain normal weight, to offset the protein catabolism associated with prolonged administration of corticosteroids, and for the relief of the bone pain frequently accompanying osteoporosis (See DOSAGE AND ADMINISTRATION). DRUG ABUSE AND DEPENDENCE Oxandrolone is classified as a controlled substance under the Anabolic Steroids Control Act of 1990 and has been assigned to Schedule III (non-narcotic).

BERTRAND, Ph.D. Centre de Recherches en Sciences de la Sante, Institut National de la Recherche Scientifique, Centre Hospitalier Louis-H. Lafontaine, Montrdal, Quebec, Canada ABSTRACT Recently developped radioimmunoassays (RIA) for the analysis of anabolic steroids and their metabolites in biological fluids were tested for cross-reactivity with other types of steroids. Results show that the degree of desirable cross-reactivity within the two classes of orally active anabolic steroids vary widely and that the antiserum for 19-Nortestosterone (the active principle of intramuscular, preparations) has a very high degree of undesirable cross- reactivity with components of oral contraceptives. Single and multiple dose studies in human volunteers demonstrate that the detection level and degree of retrospectivity are likewise variable but that the test easily detects most anabolic steroids during treatment. At the present time, the combination of the three antisera for the assay of a sample appears to be a relatively rapid and economic method for screening large numbers of samples in situations where doping control of anabolic steroids is required. The importance of utilizing physico-chemical means for identification of RIA potential positives is emphasized.

  • Androgens and Anabolic Steroids Prior Authorization with Quantity
    Androgens and Anabolic Steroids Prior Authorization with Quantity Limit Through Preferred Topical Androgen Criteria Program Summary This prior authorization program will apply only to the Oral and Topical Androgens and Anabolic Steroids. Preferred topical agents is Androgel 1.62%. This program applies to Commercial, GenPlus, NetResults A series, SourceRx and Health Insurance Marketplace formularies. Quantity limits only apply to the topical androgen agents. OBJECTIVE The intent of the Androgens and Anabolic Steroids Prior Authorization with Quantity Limit (PA) program is to appropriately select patients for therapy according to product labeling and/or clinical guidelines and/or clinical studies and according to dosing recommended in product labeling. The PA criteria will approve these agents for the FDA approved indications and off label use that is medically necessary for certain indications (e.g. AIDS/HIV-associated wasting syndrome, Turner Syndrome). In addition, the program will encourage use of two preferred topical androgen agents (Androgel and Axiron) prior to a non-preferred topical androgen agent. Use of a non-preferred topical androgen agent will be evaluated if the prescriber indicates a history of a trial of or documented intolerance, FDA labeled contraindication, or hypersensitivity to two preferred topical androgen agents. Additionally, stand-alone topical agents will not require the use of preferred topical agents, nor be a requirement prior to use of non-preferred topical agents. The program will approve only one of these agents at a time. The program will approve topical androgens for doses within the FDA labeled dosage range. Determination of quantity limits takes into account the packaging of the agents.

  • Molecular and Preclinical Pharmacology of Nonsteroidal Androgen Receptor Ligands
    Molecular and Preclinical Pharmacology of Nonsteroidal Androgen Receptor Ligands Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Amanda Jones, M.S. Graduate Program in Pharmacy The Ohio State University 2010 Dissertation Committee: James T. Dalton, Advisor Thomas D. Schmittgen William L. Hayton Robert W. Brueggemeier Copyright by Amanda Jones 2010 Abstract The androgen receptor (AR) is critical for the growth and development of secondary sexual organs, muscle, bone and other tissues, making it an excellent therapeutic target. Ubiquitous expression of AR impedes the ability of endogenous steroids to function tissue selectively. In addition to the lack of tissue selectivity, clinical use of testosterone is limited due to poor bioavailability and pharmacokinetic problems. Our lab, in the last decade, discovered and developed tissue selective AR modulators (SARMs) that spare androgenic effects in secondary sexual organs, but demonstrate potential to treat muscle wasting diseases. This work reveals the discovery of next generation SARMs to treat prostate cancer and mechanistically characterize a prospective SARM in muscle and central nervous system (CNS). Prostate cancer relies on the AR for its growth, making it the primary therapeutic target in this disease. However, prolonged inhibition, with commercially available AR antagonists, leads to the development of mutations in its ligand binding domain resulting in resistance. Utilizing the crystal structure of AR-wild-type and AR-W741L mutant, we synthesized a series of AR pan- antagonists (that inhibit both wild-type and mutant ARs). Structure activity relationship studies indicate that sulfonyl and amine linkages of the aryl propionamide pharmacophore are important for the antagonist activity.

CDGP is a transient state of hypogonadotropic hypogonadism associated with prolongation of childhood phase of growth, delayed skeletal maturation, delayed and attenuated pubertal growth spurt. In pre-pubertal male with CDGP, T therapy can be used to induce pubertal development, accelerate growth and relieve the psychosocial complaints. However, some issues in the management are still unresolved. These include type, optimal timing, dose and duration of sex steroid treatment and the possible use of adjunctive or alternate therapy. In adolescents with permanent hypogonadism T therapy is used to induce then maintain pubescent development. Testosterone therapy enables the patient to decrease mood disturbances, fatigue, impaired virilization and osteoporosis. The use of anabolic drugs to enhance athletic performance has become a major concern for professional sport organizations, sport governing bodies and governments. This mini review aims at providing an update for androgen therapy in adolescents. Endocrinologists and physicians should be acquainted with the indications, the forms, optimal timing, monitoring, dose titration and possible side-effects of T therapy to accomplish the best pharmacological outcome.
