Oxandrolone is a synthetic derivative of testosterone, classified as an anabolic steroid. It is primarily used to promote weight gain in various conditions that lead to weight loss, such as severe burns, chronic infections, or surgery. Additionally, oxandrolone is sometimes prescribed to treat bone pain associated with osteoporosis and to offset protein catabolism caused by prolonged corticosteroid therapy.
Recommended Dose and Dosage Regimen
The recommended dose of oxandrolone varies depending on the indication, patient age, and individual response to treatment. In adults, the typical starting dose for promoting weight gain ranges from 2.5 mg to 20 mg per day, divided into two to four doses. For pediatric patients, the dose is usually lower and adjusted based on body weight and growth response. Dosage adjustments may be necessary over time to achieve the desired therapeutic effect while minimizing the risk of adverse effects.
Frequency of Administration
Oxandrolone is typically administered orally, with dosing frequency ranging from once daily to multiple times per day, depending on the prescribed dose and treatment regimen. To maintain consistent blood levels of the medication, it is important to adhere to the prescribed dosing schedule and take oxandrolone at the same times each day.
Route of Administration
Oxandrolone is available in oral tablet form for administration by mouth. The tablets should be swallowed whole with a full glass of water and may be taken with or without food. Crushing or chewing the tablets should be avoided to prevent rapid release and potential gastrointestinal irritation.
Mechanism of Action (MOA)
Oxandrolone exerts its anabolic effects by binding to androgen receptors in target tissues, such as skeletal muscle, bone, and fat cells. Through this mechanism, oxandrolone promotes nitrogen retention, protein synthesis, and muscle growth, while inhibiting protein breakdown and catabolism. These anabolic actions contribute to increased lean body mass, improved muscle strength, and enhanced recovery from catabolic conditions.
Pharmacokinetics (PK)
Following oral administration, oxandrolone is rapidly absorbed from the gastrointestinal tract, with peak plasma concentrations reached within 1 to 2 hours. The bioavailability of oxandrolone is relatively high, estimated to be around 97%, but it undergoes extensive first-pass metabolism in the liver before reaching systemic circulation. Oxandrolone is primarily metabolized by hepatic enzymes and excreted in the urine as glucuronide and sulfate conjugates.
Pharmacodynamics (PD)
Oxandrolone’s pharmacodynamic effects are mediated by its interaction with androgen receptors, leading to anabolic responses in target tissues. These effects include increased protein synthesis, nitrogen retention, and muscle mass accrual, along with improvements in bone density and strength. Oxandrolone also exhibits mild androgenic activity, contributing to its anabolic effects without significant androgenic side effects.
Indications
- Promotion of weight gain following severe trauma, surgery, or chronic infection
- Treatment of osteoporosis to increase bone density and reduce fracture risk
- Adjunctive therapy for patients with HIV/AIDS-related wasting syndrome
- Management of protein catabolism associated with prolonged corticosteroid use
Contraindications
- Hypersensitivity to oxandrolone or any component of the formulation
- History of prostate or breast cancer in men
- Pregnancy or breastfeeding due to potential teratogenic effects on fetal development
Precautions
- Use oxandrolone with caution in patients with hepatic dysfunction, as it may exacerbate liver disease or impair liver function tests.
- Regular monitoring of liver enzymes, lipid profiles, and blood glucose levels is recommended during oxandrolone therapy to detect potential adverse effects.
- Long-term use of oxandrolone may increase the risk of hepatotoxicity, cardiovascular events, and alterations in lipid metabolism.
Side Effects
- Common side effects of oxandrolone may include:
- Hepatotoxicity, including elevated liver enzymes and jaundice
- Cardiovascular effects, such as hypertension, dyslipidemia, and myocardial infarction
- Androgenic effects, including acne, hirsutism, and male-pattern baldness
- Serious adverse effects, although rare, may include liver tumors, peliosis hepatis, and virilization in women.
Usage Instructions
- Take oxandrolone exactly as prescribed by a healthcare provider, following the recommended dose and dosing schedule.
- Swallow the tablets whole with a full glass of water, with or without food.
- Do not crush or chew the tablets, as this may increase the risk of gastrointestinal irritation.
- If a dose is missed, take it as soon as remembered, unless it is almost time for the next scheduled dose. Do not double the dose to make up for a missed one.
Conclusion
Oxandrolone is a synthetic anabolic steroid used primarily to promote weight gain and muscle growth in various medical conditions associated with weight loss and protein catabolism. Understanding its recommended dose, frequency of administration, route of administration, mechanism of action, pharmacokinetics, pharmacodynamics, indications, contraindications, precautions, side effects, and usage instructions is essential for safe and effective use in patients requiring anabolic therapy. Close monitoring and regular follow-up are necessary to assess treatment response, detect adverse effects, and adjust therapy as needed to optimize clinical outcomes.
