Android (Methyltestosterone) - Summary



Brand of
Capsules USP, 10 mg C-III
Rx only

The androgens are steroids that develop and maintain primary and secondary male sex characteristics. Androgens are derivatives of cyclopentanoperhydrophenanthrene. Endogenous androgens are C-19 steroids with a side chain at C-17, and with two angular methyl groups. Testosterone is the primary endogenous androgen. In their active form, all drugs in the class have a 17-beta hydroxy group. 17-alpha alkylation (methylTESTOSTERone) increases the pharmacologic activity per unit weight compared to testosterone when given orally. MethylTESTOSTERone, a synthetic derivative of testosterone, is an androgenic preparation given by the oral route in a capsule form. Each capsule contains 10 mg of MethylTESTOSTERone USP.

1. Males

Androgens are indicated for replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone:

  1. Primary hypogonadism (congenital or acquired) — testicular failure due to cryptorchidism, bilateral torsions, orchitis, vanishing testis syndrome; or orchidectomy.

  2. Hypogonadotropic hypogonadism (congenital or acquired) — idiopathic gonadotropin or LHRH deficiency, or pituitary hypothalamic injury from tumors, trauma, or radiation. If the above conditions occur prior to puberty, androgen replacement therapy will be needed during the adolescent years for development of secondary sexual characteristics. Prolonged androgen treatment will be required to maintain sexual characteristics in these and other males who develop testosterone deficiency after puberty.

  3. Androgens may be used to stimulate puberty in carefully selected males with clearly delayed puberty. These patients usually have a familial pattern of delayed puberty that is not secondary to a pathological disorder; puberty is expected to occur spontaneously at a relatively late date. Brief treatment with conservative doses may occasionally be justified in these patients if they do not respond to psychological support. The potential adverse effect on bone maturation should be discussed with the patient and parents prior to androgen administration. An X-ray of the hand and wrist to determine bone age should be obtained every 6 months to assess the effect of treatment on the epiphyseal centers (see WARNINGS).

2. Females

Androgens may be used secondarily in women with advancing inoperable metastatic (skeletal) mammary cancer who are 1 to 5 years postmenopausal. Primary goals of therapy in these women include ablation of the ovaries. Other methods of counteracting estrogen activity are adrenalectomy, hypophysectomy, and/or antiestrogen therapy. This treatment has also been used in premenopausal women with breast cancer who have benefitted from oophorectomy and are considered to have a hormone-responsive tumor. Judgment concerning androgen therapy should be made by an oncologist with expertise in this field.

Published Studies Related to Android (Methyltestosterone)

Safety and efficacy of low-dose esterified estrogens and methyltestosterone, alone or combined, for the treatment of hot flashes in menopausal women: a randomized, double-blind, placebo-controlled study. [2011.01]
This study evaluated safety and efficacy of esterified estrogens and methyltestosterone administered alone or in combination for the treatment of hot flashes in menopausal women. The 0.30-mg esterified estrogens and 0.30-mg methyltestosterone combination was the lowest effective dose, and our results are consistent with the known safety profile of estrogen and androgen combination products.

Effects of methyltestosterone on immunity against Salmonella Pullorum in dwarf chicks. [2009.12]
This study was conducted to determine effects of methyltestosterone on innate immunity and adaptive immunity against Salmonella Pullorum in dwarf chicks. In vivo experiment, comparisons of pathological sections, viable counts of bacteria, specific antibody levels, and subsets of T lymphocytes were set forth between chicks with or without 10(-7) M methyltestosterone treatment (2 d of age through 21 d of age) and challenged with 5 x 10(8) virulent Salmonella Pullorum (7 d of age), and in vitro experiment, phagocytic and killing abilities, reactive oxygen intermediate production, and reactive nitrogen intermediate production of monocytes-macrophages treated with high (10(-8) M/10(6) cell) or physiological (10(-14) M/10(6) cell) concentration of methyltestosterone were examined after Salmonella Pullorum infection...

Effects of the addition of methyltestosterone to combined hormone therapy with estrogens and progestogens on sexual energy and on orgasm in postmenopausal women. [2008.02]
OBJECTIVE: To evaluate the effect of the addition of methyltestosterone to estrogen and progestogen therapy on postmenopausal sexual energy and orgasm... CONCLUSION: Addition of methyltestosterone to CEE/MPA therapy may increase sexual energy, but might not affect the ability to obtain orgasm in sexual relations.

Efficacy of hormone therapy with and without methyltestosterone augmentation of venlafaxine in the treatment of postmenopausal depression: a double-blind controlled pilot study. [2006.03]
OBJECTIVE: This study evaluated the augmentation of venlafaxine with hormone therapy in the treatment of postmenopausal depression. The hormones evaluated were estrogen (0.625 mg) in combination with medroxyprogesterone acetate (2.5 mg) and methyltestosterone (2.5 mg)... CONCLUSIONS: Methyltestosterone 2.5 mg had the highest effect size compared with placebo, but the high dropout rate prevented its efficacy from being determined. Estrogen plus medroxyprogesterone, combined with methyltestosterone or otherwise, demonstrated a trend toward increased efficacy of venlafaxine. Further larger-scale clinical trials are needed to elucidate the findings of this pilot study.

[Effects of growth hormone on anthropometric and metabolic parameters in android obesity] [2006.02]
The aim of the study was to evaluate the effect of GH on body weight, body composition and cardiovascular risk factors in android obese men. Forty non-diabetic subjects aged 20 to 50 years-old with android obesity (WHR > 1) were divided in two groups, on a prospective randomized double-blind basis to receive treatment with GH (0.050 U/kg/day) or placebo for three months...

Feasibility of Use of BariCare App in Pre-bariatric Surgery. [Recruiting]
This current study aims to evaluate the efficacy of engagement modules in preparing patients for bariatric surgery. With the help of the Center for Innovation (CFI), a smartphone app (Android and Apple compatible) has been created that will assist in both educating and engaging patients to develop and maintain healthy lifestyle modifications. Our goal is to create a cost-effective, smartphone-based platform that serves to not only efficiently educate but to also verify competence and keep our patients engaged during the lengthy pre-bariatric surgery process.

Development of an Advisory System for Glycemic Control During the Menstrual Cycle in Patient With Type 1 Diabetes [Recruiting]
This overall research goal will be to develop a mobile-based module to improve glycemic control during the menstrual cycle in women with Type 1 diabetes mellitus (T1DM). This module will run on an Android Operating System (OS) and will be available as: (i) a stand-alone application and (ii) an important additional component to a larger system, the

Diabetes Assistant (DiAs) - a mobile-based medical platform for diabetes applications. This

proposal aims to build one such application or module targeting the improvement of diabetes control in younger women who experience glucose variation related to their menstrual cycle.

Evaluation of the Impact of Physical Reconditioning Associated With Specific Nutritional Supplementation in Obese Patients Suffering From Metabolic Syndrome [Recruiting]
Android obesity contributes, via insulin resistance and endothelial dysfunction, to the development of cardiovascular atherosclerosis. It leads to poor quality of life. It is often associated with metabolic syndrome which includes, whatever the definitions used (National Education Cholesterol Program, NECP / Adult Treatment Panel III, ATP III or International Diabetes Federation, IDF), an increased waist measurement, an arterial high blood pressure and disorders of the glucide and lipid metabolism. The treatment of the current "epidemic" of obesity and metabolic syndrome in France (12. 4 % of obese and 14 % of subjects with metabolic syndrome) thus requires new therapeutic approaches.

A well-balanced diet and a daily physical activity are the indispensable requirements for the treatment of obesity and metabolic syndrome. It is possible to associate it to pharmacological agents, but the results are often partial and transient. Preliminary data suggest that leucine or arginine supplementation could facilitate the loss of fat mass. Moreover, the physical exercise has also demonstrated benefits.

Sessions of physical reconditioning (aerobic work + muscular intensification) associated with a program of specific nutritional supplementation by a mixture of Leucine and Arginine (in the daytime) could improve the treatment of obese subjects affected by metabolic syndrome.
