Actions & Spectrum

Actions and Spectrum: oxandrolone is a synthetic anabolic steroid, also known as “Anavar”. It is primarily used to help patients regain the weight they have lost due to certain medical conditions such as surgery, chronic infection, or severe trauma. In terms of its actions, oxandrolone promotes muscle growth and increases the production of red blood cells, which can enhance endurance and athletic performance. It also has mild androgenic effects, which can promote the development of male characteristics such as a deeper voice and facial hair growth. The spectrum of oxandrolone’s effects is relatively mild compared to other anabolic steroids, making it a popular choice for individuals who want to enhance their athletic performance or physical appearance without experiencing the more extreme side effects associated with other steroids.

Black Box Warning

The adverse conditions reported due to androgen therapy of anabolic steroids are peliosis, hepatitis, liver cell tumors, and changes in the blood lipid level.

Contraindication / Caution

Contraindication/Caution: oxandrolone has several contraindications and precautions that should be considered before use:

  • Allergy: Individuals allergic to oxandrolone or any of its components should not use this medication.
  • Pregnancy and breastfeeding: oxandrolone can harm a developing fetus and should not be used during pregnancy or breastfeeding.
  • Liver disease: oxandrolone can cause liver damage and should be used cautiously in individuals with liver disease or a history of liver damage.
  • Prostate cancer: oxandrolone can stimulate the growth of prostate cancer cells and should not be used by individuals with a history of prostate cancer.
  • High cholesterol: oxandrolone can increase cholesterol levels in the blood and should be used cautiously in individuals with high cholesterol.
  • Cardiovascular disease: oxandrolone can increase the risk of cardiovascular disease, including heart attack and stroke, and should be used cautiously in individuals with a history of cardiovascular disease.
  • Diabetes: oxandrolone can affect blood sugar levels and should be used cautiously in individuals with diabetes.
  • Children: oxandrolone should not be used in children unless specifically prescribed by a healthcare professional.

Pregnancy / Lactation

Pregnancy consideration: Category X

Breastfeeding warnings: Do not breastfeed if taking oxandrolone

Pregnancy category:

  • Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester.
  • Category B: No evidence shown of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women.
  • Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a human product; Pregnant women must take care of the potential risks.
  • Category D: There is adequate data with sufficient evidence of human fetal risk from various platforms. However, despite potential dangers may be used only in emergencies for potential benefits.
  • Category X: Drugs listed in this category outweigh risks over benefits. The drug is not for pregnant women.
  • Category N: No data is available for the drug under this category.

Pharmacology

Pharmacology: oxandrolone is an orally administered synthetic anabolic steroid derived from dihydrotestosterone. It has a high oral bioavailability, meaning it is absorbed well from the gastrointestinal tract and quickly reaches high blood levels. Once absorbed, oxandrolone is metabolized primarily in the liver and excreted in the urine. It has a half-life of approximately 9 hours, eliminating it from the body relatively quickly compared to other anabolic steroids. oxandrolone also has a mild androgenic effect, which can promote the development of male characteristics such as a deeper voice and facial hair growth. However, this effect is relatively mild compared to other anabolic steroids.

Pharmacodynamics:

The pharmacodynamics of oxandrolone involves its effects on the body’s tissues and cells. oxandrolone is a synthetic derivative of dihydrotestosterone (DHT), a hormone that plays a role in developing and maintaining male sexual characteristics. Like other anabolic steroids, oxandrolone works by binding to androgen receptors in cells throughout the body. This binding activates specific genetic pathways that stimulate the synthesis of proteins, leading to increased muscle mass, strength, and endurance. oxandrolone can also stimulate the production of red blood cells, enhancing athletic performance and endurance. oxandrolone has a relatively mild androgenic effect compared to other anabolic steroids, which means that it is less likely to cause masculinizing effects such as deepening of the voice and facial hair growth in women. However, it can still cause these effects in high doses or prolonged use. oxandrolone has also shown potential therapeutic benefits for specific medical conditions, including muscle wasting associated with HIV/AIDS, osteoporosis, and Turner syndrome.

Pharmacokinetics:
Absorption

oxandrolone is administered orally and is rapidly absorbed from the gastrointestinal tract, with peak blood levels reached within 1-2 hours after ingestion.

Distribution

Once absorbed, oxandrolone is transported by the bloodstream and distributed to various tissues throughout the body. It has a relatively low binding affinity for plasma proteins, meaning it can freely circulate in the bloodstream.

Metabolism

oxandrolone is primarily metabolized in the liver, with most of the drug converted into inactive metabolites. The main metabolic pathway involves the reduction of the ketone group on the oxandrolone molecule, which results in the formation of 17β-hydroxy-17α-methyl-5α-androstane-3-one (17β-OHMethyl-DHT).

Elimination and Excretion

oxandrolone and its metabolites are eliminated from the body primarily through urine, with a small amount being excreted in the feces. The elimination half-life of oxandrolone is approximately 9 hours, which means that it is cleared from the body relatively quickly compared to other anabolic steroids.

Administration

oxandrolone is typically administered orally in the form of tablets. The dosing and administration of oxandrolone depend on the medical condition being treated and the individual patient’s age, weight, and overall health status. Here are some general guidelines for the administration of oxandrolone:

  • For treating muscle wasting: The usual dose of oxandrolone is 2.5-20 mg
