*Peliosis hepatis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, has been reported in patients receiving androgenic anabolic steroid therapy. these cysts are sometimes present with minimal hepatic dysfunction, but at other times they have been associated with liver failure. They are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops. withdrawal of drug usually results in complete disappearance of lesions. Liver cell tumors are also reported. Most often these tumors are benign and androgen-dependent, but fatal malignant tumors have been reported. Withdrawal of drug often results in regression or cessation of progression of the tumor. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening intra-abdominal hemorrhage develops. Blood lipid changes that are known to be associated with increased risk of atherosclerosis are seen in patients treated with androgens or anabolic steroids. These changes include decreased high-density lipoproteins and sometimes increased low-density lipoproteins. The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.

=====Weight Loss=====
 
*Oxandrolone 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.
 
*Therapy with anabolic steroids is adjunctive to and not a replacement for conventional therapy. The duration of therapy with oxandrolone will depend on the response of the patient and the possible appearance of adverse reactions. Therapy should be intermittent.
 
*The response of individuals to anabolic steroids varies. The daily adult dosage is 2.5 mg to 20 mg given in 2 to 4 divided doses. The desired response may be achieved with as little as 2.5 mg or as much as 20 mg daily. A course of therapy of 2 to 4 weeks is usually adequate. This may be repeated intermittently as indicated.

<!--Contraindications-->
 
|contraindications=
 
*Known or suspected [[prostate cancer]] or the [[male breast]].
 
*[[Breast cancer]] in females with [[hypercalcemia]] (androgenic [[anabolic steroids]] may stimulate [[osteolytic]] bone resorption).
 
*[[Pregnancy]], because of possible [[masculinization]] of the fetus. Oxandrolone has been shown to cause embryotoxicity, fetotoxicity, [[infertility]], and masculinization of female animal offspring when given in doses 9 times the human dose.
 
*[[Nephrosis]], the nephrotic phase of [[nephritis]].
 
*[[Hypercalcemia]].
 
<!--Warnings-->
 
|warnings=
 
*Cholestatic [[hepatitis]] and [[jaundice]] may occur with 17-alpha-alkylated [[androgens]] at a relatively low dose. If cholestatic hepatitis with [[jaundice]] appears or if liver function tests become abnormal, oxandrolone should be discontinued and the etiology should be determined. Drug-induced [[jaundice]] is reversible when the medication is discontinued.
 
*In patients with [[breast cancer]], anabolic steroid therapy may cause [[hypercalcemia]] by stimulating [[osteolysis]]. Oxandrolone therapy should be discontinued if hypercalcemia occurs.
 
*[[Edema]] with or without [[congestive heart failure]] may be a serious complication in patients with pre-existing cardiac, renal, or hepatic disease. Concomitant administration of adrenal cortical [[steroid]] or [[ACTH]] may increase the [[edema]].
 
*In children, androgen therapy may accelerate bone maturation without producing compensatory gain in linear growth. This adverse effect results in compromised adult height. The younger the child, the greater the risk of compromising final mature height. The effect on bone maturation should be monitored by assessing bone age of the left wrist and hand every 6 months.
 
*Geriatric patients treated with androgenic anabolic steroids may be at an increased risk for the development of [[prostatic hypertrophy]] and prostatic carcinoma.
 
*Anabolic steroids have not been shown to enhance athletic ability.
 
====Precautions====
 
* Concurrent dosing of oxandrolone with [[warfarin]] may result in unexpectedly large increases in the [[INR]] or [[prothrombin time]] (PT). When oxandrolone is prescribed to patients being treated with [[warfarin]], doses of warfarin may need to be decreased significantly to maintain the desirable INR level and diminish the risk of potentially serious bleeding.
 
*General
:*Women should be observed for signs of [[virilization]] (deepening of the voice, [[hirsutism]], [[acne]], [[clitoromegaly]]). Discontinuation of drug therapy at the time of evidence of mild [[virilism]] is necessary to prevent irreversible [[virilization]]. Some virilizing changes in women are irreversible even after prompt discontinuance of therapy and are not prevented by concomitant use of [[estrogens]]. Menstrual irregularities may also occur.
:*Anabolic steroids may cause suppression of [[clotting factors]] II, V, VII, and X, and an increase in [[prothrombin time]].
 
<!--Adverse Reactions-->
 
<!--Clinical Trials Experience-->
 
|clinicalTrials=
 
*Patients with moderate to severe COPD or COPD patients who are unresponsive to [[bronchodilators]] should be monitored closely for COPD exacerbation and fluid retention.
 
*The following adverse reactions have been associated with use of anabolic steroids: Hepatic: Cholestatic [[jaundice]] with, rarely, hepatic necrosis and death. Hepatocellular neoplasms and [[peliosis hepatis]] with long-term therapy. Reversible changes in liver function tests also occur including increased bromsulfophthalein (BSP) retention, changes in alkaline phosphatase and increases in serum [[bilirubin]], [[aspartate aminotransferase]] (AST, SGOT) and alanine aminotransferase (ALT, SGPT)
 
*In males:
:*Prepubertal: Phallic enlargement and increased frequency or persistence of erections.
:*Postpubertal: Inhibition of testicular function, testicular atrophy and [[oligospermia]], [[impotence]], chronic [[priapism]], [[epididymitis]], and bladder irritability.
 
*In females:
:*[[Clitoromegaly]], menstrual irregularities.

<!--Drug Interactions-->
 
|drugInteractions=
 
* Anticoagulants
:*Anabolic steroids may increase sensitivity to oral [[anticoagulants]]. Dosage of the anticoagulant may have to be decreased in order to maintain desired prothrombin time. Patients receiving oral anticoagulant therapy require close monitoring, especially when anabolic steroids are started or stopped.
 
*Warfarin
:*A multidose study of oxandrolone, given as 5 or 10 mg bid in 15 healthy subjects concurrently treated with [[warfarin]], resulted in a mean increase in S-warfarin half-life from 26 to 48 hours and AUC from 4.55 to 12.08 ng*hr/mL; similar increases in R-warfarin half-life and AUC were also detected. Microscopic [[hematuria]] (9/15) and [[gingival bleeding]] (1/15) were also observed. A 5.5-fold decrease in the mean warfarin dose from 6.13 mg/day to 1.13 mg/day (approximately 80-85% reduction of warfarin dose), was necessary to maintain a target INR of 1.5. When oxandrolone therapy is initiated in a patient already receiving treatment with warfarin, the INR or [[prothrombin time]] (PT) should be monitored closely and the dose of warfarin adjusted as necessary until a stable target INR or PT has been achieved. Furthermore, in patients receiving both drugs, careful monitoring of the INR or PT, and adjustment of the warfarin dosage if indicated are recommended when the oxandrolone dose is changed or discontinued. Patients should be closely monitored for signs and symptoms of occult bleeding.
 
*Oral hypoglycemic agents
:*Oxandrolone may inhibit the metabolism of [[oral hypoglycemic agent]]s.
 
*Adrenal steroids or ACTH
:*In patients with [[edema]], concomitant administration with adrenal cortical steroids or [[ACTH]] may increase the [[edema]].

|useInPed=
 
*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, therapy should be monitored by x-ray studies at 6-month intervals in order to avoid the risk of compromising adult height.

{{SI}}
'''Oxandrolone''' ('''Oxandrin''') is an [[anabolic steroid]] created by [[Searle Laboratories]] under the trademark '''Anavar''', and introduced into the US in 1964. It is taken orally, and unlike other steroids delivered in this manner, most of which are Class II steroids, the majority of its effects are due to reaction with the [[androgen receptor]]. In sufficient dosage, Oxandrolone is highly likely to bind well with the receptor, and is therefore a Class I steroid, while having few other side-effects.


As opposed to most other anabolic steroids Oxandrolone has two major advantages: First of all it does not aromatize (convert to estrogen which causes gynecomastia - breast tissue) and it does not significantly influence on low dosages (10mg) body's normal testosterone production (HPTA axis). When dosages are high (this goes for any anabolic steroid) then your body feels that it has enough testosterone and it reduces the production of LH (luteinizing hormone) which no longer stimulates Leydig cells in testicles to produce testosterone therefore causing testicular atrophy (shrinking).
<!--Mechanism of Action-->
Post Cycle Therapy (PCT) is of course needed for high dosages (40-50mg) of this synthetic derivative of testosterone because as the dosage increases the influence on HPTA is bigger. Lack of PCT will of course lead to protein catabolism until body's normal testosterone secretion is back to normal.
 
|mechAction=
 
*Anabolic steroids are synthetic derivatives of [[testosterone]]. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. 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 hormone]] (LH). At large doses, [[spermatogenesis]] may be suppressed through feedback inhibition of pituitary [[follicle-stimulating hormone]] (FSH)
 
<!--Structure-->
 
|structure=
 
* Oxandrolone oral tablets contain 2.5 mg or 10 mg of the anabolic steroid oxandrolone. Oxandrolone is 17β-hydroxy-17α-methyl-2-oxa-5α-androstan-3-one with the following structural formula:

*Inactive ingredients include cornstarch, lactose, magnesium stearate, and hydroxypropyl methylcellulose.
 
<!--Pharmacodynamics-->
 
|PD=
 
There is limited information regarding <i>Pharmacodynamics</i> of {{PAGENAME}} in the drug label.
 
<!--Pharmacokinetics-->
 
|PK=
 
*In a single dose pharmacokinetic study of oxandrolone in elderly subjects, the mean elimination half-life was 13.3 hours. In a previous single dose pharmacokinetic study in younger volunteers, the mean elimination half-life was 10.4 hours. No significant differences between younger and elderly volunteers were found for time to peak, peak plasma concentration or AUC after a single dose of oxandrolone. The correlation between plasma level and therapeutic effect has not been defined.
 
<!--Nonclinical Toxicology-->
 
|nonClinToxic=
 
*Oxandrolone has not been tested in laboratory animals for carcinogenic or mutagenic effects. In 2-year chronic oral rat studies, a dose-related reduction of spermatogenesis and decreased organ weights (testes, prostate, seminal vesicles, ovaries, uterus, adrenals, and pituitary) were shown.

<!--Look-Alike Drug Names-->


The drug was prescribed for a number of medical disorders causing involuntary weight loss, in order to promote muscle regrowth. It had also been shown to be partially successful in treating cases of [[osteoporosis]]. However, in part due to bad publicity from its abuses by bodybuilders, Oxandrolone was discontinued by Searle Laboratories in 1989. It was picked up by Bio-Technology General Corporation, now Savient Pharmaceuticals, Inc. who, following successful clinical trials in 1995, released it under the tradename Oxandrin.
|lookAlike=


It was approved for orphan drug status by the [[Food and Drug Administration]] (FDA) in treating alcoholic hepatitis, Turner's syndrome, and weight loss caused by HIV. In addition, the drug has shown positive results in treating anaemia and hereditary angioedema.
<!--Drug Shortage Status-->
In a randomized, double-blind study,  patients with 40% total body surface area burns were selected to receive standard burn care plus Oxandrolone, or without Oxandrolone. Those treated with Oxandrolone showed improve body composition, preserved muscle mass and reduced hospital stay time. <ref name="S">[http://www.shrinershq.org/Hospitals/Galveston Shriners Burns Hospital for Children]. The Effect of Oxandrolone On the Endocrinologic, Inflammatory and Hypermetabolic Responses During the Acute Phase Postburn. 2006.  [http://www.americansurgical.info/abstracts/2007/1.cgi]</ref> Other studies however have shown links between prolonged use of the drug and problems of [[Cirrhosis|liver toxicity]] similar to those found with other 17α-alkylated steroids. Even in small dosages, many users reported [[Gastro-intestinal tract|gastro-intestinal]] problems such as [[bloating]], [[nausea]], skin rash and itching (hives), black, tarry stools or light-colored stools, depression, unusual bleeding, unusual swelling, yellowing of the eyes or skin,  and [[diarrhoea]].


In rare cases, serious and even fatal cases of liver problems have developed during treatment with oxandrolone. Oxandrolone may increase the amount of low density lipoprotein (LDL; 'bad cholesterol') and decrease the amount of high density lipoprotein (HDL; 'good cholesterol') in the blood. This may increase the risk of developing heart disease. Oxandrolone may damage the liver or increase LDL without causing symptoms. It is important to have regular laboratory tests to be sure that the liver is working properly and that LDL has not increased. Oxandrolone may also decrease fertility in men.

Before the [[Controlled Substances Act]] was passed to restrict the production, sale, and usage of anabolic steroids, Oxandrolone's characteristics lent itself well towards use by female athletes. Its specificity targeting the androgen receptor meant that, unlike many other steroids, it had not been reported to cause stunted growth in younger users (because it doesn't convert to estrogen, thats the reason women typically don't grow as tall as men -- they have more estrogen) and at typical dosage rarely caused noticeable  masculinising effects outside of stimulating muscle growth. It is not easily metabolised into [[Dihydrotestosterone|DHT]] or [[estrogen]]. As such, a typical dose of 20-30 [[milligram|mg]] provided elevated [[androgen]] levels for up to eight hours. To increase effectiveness, bodybuilders typically "stacked" the drug with others such as [[Testosterone]], further enhancing body mass gain.

Besides the obvious health risks (liver and coronary), the biggest problem with Oxandrolone  (and with any anabolic steroid) is of course abuse and addiction without the supervision of a physician. Addiction rate for steroids is so high that the U.S. Controlled Substances Act considers anabolic steroids a Schedule III drug therefore even possession is a felony. Abuse being one major problem most bodybuilders  consider a normal dose for a novice being 20-30mg's per day when in fact 10 mg is more then enough for someone who never had used. Higher dosages not only lead to AR (Androgen Receptor) damage and HPTA suppression but also damages the liver being a 17α-alkylated. It is specially made 17α-alkylated because if it would not be then the liver would consider it a toxin and would destroy it.

Black Box Warning

WARNING
See full prescribing information for complete Boxed Warning.
  • Peliosis hepatis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, has been reported in patients receiving androgenic anabolic steroid therapy. these cysts are sometimes present with minimal hepatic dysfunction, but at other times they have been associated with liver failure. They are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops. withdrawal of drug usually results in complete disappearance of lesions. Liver cell tumors are also reported. Most often these tumors are benign and androgen-dependent, but fatal malignant tumors have been reported. Withdrawal of drug often results in regression or cessation of progression of the tumor. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening intra-abdominal hemorrhage develops. Blood lipid changes that are known to be associated with increased risk of atherosclerosis are seen in patients treated with androgens or anabolic steroids. These changes include decreased high-density lipoproteins and sometimes increased low-density lipoproteins. The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.

Overview

Oxandrolone is an anabolic steroid that is FDA approved for the {{{indicationType}}} of 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. There is a Black Box Warning for this drug as shown here. Common adverse reactions include edema, increased risk of atherosclerosis, cholestatic hepatitis, jaundice, testicular atropy, erectile dysfunction, and priapism.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Weight Loss
  • Oxandrolone 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.
  • Therapy with anabolic steroids is adjunctive to and not a replacement for conventional therapy. The duration of therapy with oxandrolone will depend on the response of the patient and the possible appearance of adverse reactions. Therapy should be intermittent.
  • The response of individuals to anabolic steroids varies. The daily adult dosage is 2.5 mg to 20 mg given in 2 to 4 divided doses. The desired response may be achieved with as little as 2.5 mg or as much as 20 mg daily. A course of therapy of 2 to 4 weeks is usually adequate. This may be repeated intermittently as indicated.

Off-Label Use and Dosage (Adult)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Oxandrolone in adult patients.

Non–Guideline-Supported Use

Alcoholic hepatitis
  • Oxandrolone (80 milligrams daily).[1]
Burn, Severe; Adjunct
  • Oxandrolone 20 mg/day in 2 divided doses.[2]
Cachexia associated with AIDS
  • Oxandrolone 20 milligrams.[3]

Pediatric Indications and Dosage

FDA-Labeled Indications and Dosage (Pediatric)

Weight Loss
  • The total daily dosage of oxandrolone is ≤0.1 mg per kilogram body weight or ≤0.045 mg per pound of body weight. This may be repeated intermittently as indicated.

Off-Label Use and Dosage (Pediatric)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Oxandrolone in pediatric patients.

Non–Guideline-Supported Use

Burn, Severe; Adjunct
  • Oxandrolone 0.1 mg/kg orally twice daily.[4]
Turner syndrome
  • Oral oxandrolone in usual dosages of 0.125 mg/kg/day for 1 to 2 years.[5]

Contraindications

  • Pregnancy, because of possible masculinization of the fetus. Oxandrolone has been shown to cause embryotoxicity, fetotoxicity, infertility, and masculinization of female animal offspring when given in doses 9 times the human dose.

Warnings

WARNING
See full prescribing information for complete Boxed Warning.
  • Peliosis hepatis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, has been reported in patients receiving androgenic anabolic steroid therapy. these cysts are sometimes present with minimal hepatic dysfunction, but at other times they have been associated with liver failure. They are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops. withdrawal of drug usually results in complete disappearance of lesions. Liver cell tumors are also reported. Most often these tumors are benign and androgen-dependent, but fatal malignant tumors have been reported. Withdrawal of drug often results in regression or cessation of progression of the tumor. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening intra-abdominal hemorrhage develops. Blood lipid changes that are known to be associated with increased risk of atherosclerosis are seen in patients treated with androgens or anabolic steroids. These changes include decreased high-density lipoproteins and sometimes increased low-density lipoproteins. The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.
  • Cholestatic hepatitis and jaundice may occur with 17-alpha-alkylated androgens at a relatively low dose. If cholestatic hepatitis with jaundice appears or if liver function tests become abnormal, oxandrolone should be discontinued and the etiology should be determined. Drug-induced jaundice is reversible when the medication is discontinued.
  • Edema with or without congestive heart failure may be a serious complication in patients with pre-existing cardiac, renal, or hepatic disease. Concomitant administration of adrenal cortical steroid or ACTH may increase the edema.
  • In children, androgen therapy may accelerate bone maturation without producing compensatory gain in linear growth. This adverse effect results in compromised adult height. The younger the child, the greater the risk of compromising final mature height. The effect on bone maturation should be monitored by assessing bone age of the left wrist and hand every 6 months.
  • Geriatric patients treated with androgenic anabolic steroids may be at an increased risk for the development of prostatic hypertrophy and prostatic carcinoma.
  • Anabolic steroids have not been shown to enhance athletic ability.

Precautions

  • Concurrent dosing of oxandrolone with warfarin may result in unexpectedly large increases in the INR or prothrombin time (PT). When oxandrolone is prescribed to patients being treated with warfarin, doses of warfarin may need to be decreased significantly to maintain the desirable INR level and diminish the risk of potentially serious bleeding.
  • General
  • Women should be observed for signs of virilization (deepening of the voice, hirsutism, acne, clitoromegaly). Discontinuation of drug therapy at the time of evidence of mild virilism is necessary to prevent irreversible virilization. Some virilizing changes in women are irreversible even after prompt discontinuance of therapy and are not prevented by concomitant use of estrogens. Menstrual irregularities may also occur.
  • Anabolic steroids may cause suppression of clotting factors II, V, VII, and X, and an increase in prothrombin time.

Adverse Reactions

Clinical Trials Experience

  • Patients with moderate to severe COPD or COPD patients who are unresponsive to bronchodilators should be monitored closely for COPD exacerbation and fluid retention.
  • The following adverse reactions have been associated with use of anabolic steroids: Hepatic: Cholestatic jaundice with, rarely, hepatic necrosis and death. Hepatocellular neoplasms and peliosis hepatis with long-term therapy. Reversible changes in liver function tests also occur including increased bromsulfophthalein (BSP) retention, changes in alkaline phosphatase and increases in serum bilirubin, aspartate aminotransferase (AST, SGOT) and alanine aminotransferase (ALT, SGPT)
  • In males:
  • Prepubertal: Phallic enlargement and increased frequency or persistence of erections.
  • Postpubertal: Inhibition of testicular function, testicular atrophy and oligospermia, impotence, chronic priapism, epididymitis, and bladder irritability.
  • In females:
CNS

Habituation, excitation, insomnia, depression, and changes in libido.

Hematologic

Bleeding in patients on concomitant oral anticoagulant therapy.

Breast

Gynecomastia.

Larynx

Deepening of the voice in females.

Hair

Hirsutism and male pattern baldness in females.

Skin

Acne (especially in females and prepubertal males).

Skeletal

Premature closure of epiphyses in children.

Fluid and electrolytes

Edema, retention of serum electrolytes (sodium chloride, potassium, phosphate, calcium).

Metabolic/Endocrine

Decreased glucose tolerance, increased creatinine excretion, increased serum levels of creatinine phosphokinase (CPK). Masculinization of the fetus. Inhibition of gonadotropin secretion.

Postmarketing Experience

There is limited information regarding Postmarketing Experience of Oxandrolone in the drug label.

Drug Interactions

  • Anticoagulants
  • Anabolic steroids may increase sensitivity to oral anticoagulants. Dosage of the anticoagulant may have to be decreased in order to maintain desired prothrombin time. Patients receiving oral anticoagulant therapy require close monitoring, especially when anabolic steroids are started or stopped.
  • Warfarin
  • A multidose study of oxandrolone, given as 5 or 10 mg bid in 15 healthy subjects concurrently treated with warfarin, resulted in a mean increase in S-warfarin half-life from 26 to 48 hours and AUC from 4.55 to 12.08 ng*hr/mL; similar increases in R-warfarin half-life and AUC were also detected. Microscopic hematuria (9/15) and gingival bleeding (1/15) were also observed. A 5.5-fold decrease in the mean warfarin dose from 6.13 mg/day to 1.13 mg/day (approximately 80-85% reduction of warfarin dose), was necessary to maintain a target INR of 1.5. When oxandrolone therapy is initiated in a patient already receiving treatment with warfarin, the INR or prothrombin time (PT) should be monitored closely and the dose of warfarin adjusted as necessary until a stable target INR or PT has been achieved. Furthermore, in patients receiving both drugs, careful monitoring of the INR or PT, and adjustment of the warfarin dosage if indicated are recommended when the oxandrolone dose is changed or discontinued. Patients should be closely monitored for signs and symptoms of occult bleeding.
  • Oral hypoglycemic agents
  • Adrenal steroids or ACTH
  • In patients with edema, concomitant administration with adrenal cortical steroids or ACTH may increase the edema.

Use in Specific Populations

There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Oxandrolone in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Oxandrolone during labor and delivery.

Nursing Mothers

  • It is not known whether anabolic steroids are excreted in human milk. Because of the potential of serious adverse reactions in nursing infants from oxandrolone, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

  • 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, therapy should be monitored by x-ray studies at 6-month intervals in order to avoid the risk of compromising adult height. Androgenic anabolic steroid therapy should be used very cautiously in children and only by specialists who are aware of the effects on bone maturation.

Routes Oral

Mechanism of Action

  • Anabolic steroids are synthetic derivatives of testosterone. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. 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.

Structure

  • Oxandrolone oral tablets contain 2.5 mg or 10 mg of the anabolic steroid oxandrolone. Oxandrolone is 17β-hydroxy-17α-methyl-2-oxa-5α-androstan-3-one with the following structural formula:

  • Inactive ingredients include cornstarch, lactose, magnesium stearate, and hydroxypropyl methylcellulose.

Pharmacodynamics

There is limited information regarding Pharmacodynamics of Oxandrolone in the drug label.

Pharmacokinetics

  • In a single dose pharmacokinetic study of oxandrolone in elderly subjects, the mean elimination half-life was 13.3 hours. In a previous single dose pharmacokinetic study in younger volunteers, the mean elimination half-life was 10.4 hours. No significant differences between younger and elderly volunteers were found for time to peak, peak plasma concentration or AUC after a single dose of oxandrolone. The correlation between plasma level and therapeutic effect has not been defined.

Nonclinical Toxicology

  • Oxandrolone has not been tested in laboratory animals for carcinogenic or mutagenic effects. In 2-year chronic oral rat studies, a dose-related reduction of spermatogenesis and decreased organ weights (testes, prostate, seminal vesicles, ovaries, uterus, adrenals, and pituitary) were shown.
