Pharmaceutical Companies that Manufacture Oxandrolone
Oxandrolone, also known as Anavar, is a synthetic anabolic steroid that has been used in the medical field for various purposes, including treating muscle wasting diseases and promoting weight gain in patients with chronic illnesses. However, it has also gained popularity in the sports world due to its ability to enhance athletic performance and improve muscle mass. As a result, there has been an increase in demand for oxandrolone, leading to the production of this substance by various pharmaceutical companies.
History of Oxandrolone
Oxandrolone was first developed in 1962 by pharmaceutical company Searle Laboratories (now known as Pfizer) and was approved by the FDA for medical use in 1964. It was initially used to treat muscle wasting diseases such as HIV/AIDS and osteoporosis, as well as to promote weight gain in patients with chronic illnesses. However, it was later discovered that oxandrolone also had anabolic properties, making it popular among athletes and bodybuilders.
In the 1970s, Searle Laboratories stopped producing oxandrolone due to the high cost of production. However, it was later reintroduced in the market by another pharmaceutical company, Savient Pharmaceuticals, under the brand name Oxandrin. Today, there are several pharmaceutical companies that manufacture oxandrolone, including Pfizer, Savient Pharmaceuticals, and Watson Laboratories.
Pharmacokinetics and Pharmacodynamics of Oxandrolone
Oxandrolone is a synthetic derivative of dihydrotestosterone (DHT) and has a high anabolic to androgenic ratio, meaning it has a greater effect on muscle growth compared to its androgenic effects. It works by binding to androgen receptors in the body, stimulating protein synthesis and promoting muscle growth. It also has a low affinity for binding to sex hormone-binding globulin (SHBG), which allows it to remain active in the body for longer periods.
The half-life of oxandrolone is approximately 9 hours, and it is primarily metabolized in the liver. It is excreted in the urine as glucuronide and sulfate conjugates. The recommended dosage for medical use is 2.5-20mg per day, while athletes and bodybuilders may take higher doses ranging from 20-80mg per day. However, it is important to note that the use of oxandrolone for non-medical purposes is illegal and can lead to serious health consequences.
Pharmaceutical Companies that Manufacture Oxandrolone
As mentioned earlier, there are several pharmaceutical companies that manufacture oxandrolone. These include:
- Pfizer: Pfizer is one of the largest pharmaceutical companies in the world and is the original manufacturer of oxandrolone. They produce oxandrolone under the brand name Oxandrin, which is available in 2.5mg and 10mg tablets.
- Savient Pharmaceuticals: Savient Pharmaceuticals acquired the rights to manufacture oxandrolone from Searle Laboratories in the 1990s. They produce oxandrolone under the brand name Oxandrin, which is available in 2.5mg and 10mg tablets.
- Watson Laboratories: Watson Laboratories is a subsidiary of Teva Pharmaceuticals and is one of the largest generic drug manufacturers in the world. They produce oxandrolone under the brand name Anavar, which is available in 2.5mg and 10mg tablets.
Uses of Oxandrolone
Oxandrolone has been primarily used for medical purposes, including treating muscle wasting diseases and promoting weight gain in patients with chronic illnesses. However, it has also gained popularity in the sports world due to its ability to enhance athletic performance and improve muscle mass. Some athletes and bodybuilders also use oxandrolone during cutting cycles to maintain muscle mass while losing body fat.
Additionally, oxandrolone has been used in the treatment of burn injuries, as it has been shown to improve wound healing and reduce muscle loss. It has also been used in the treatment of osteoporosis, as it has been shown to increase bone density and reduce the risk of fractures.
Side Effects of Oxandrolone
Like any other anabolic steroid, oxandrolone can cause a range of side effects, including:
- Suppression of natural testosterone production
- Acne
- Hair loss
- Increased risk of cardiovascular disease
- Liver toxicity
- Virilization in women
It is important to note that the severity and frequency of these side effects may vary depending on the dosage and duration of use. It is also essential to consult a healthcare professional before using oxandrolone to ensure safe and responsible use.
Conclusion
Oxandrolone, also known as Anavar, is a synthetic anabolic steroid that has been used for medical purposes since the 1960s. It has gained popularity in the sports world due to its ability to enhance athletic performance and improve muscle mass. Today, there are several pharmaceutical companies that manufacture oxandrolone, including Pfizer, Savient Pharmaceuticals, and Watson Laboratories. However, it is important to note that the use of oxandrolone for non-medical purposes is illegal and can lead to serious health consequences. It is essential to consult a healthcare professional before using oxandrolone to ensure safe and responsible use.
Expert Comments
