**Stanozolol** is a synthetic anabolic steroid, commonly known as **Winstrol**, which is widely used in medical and non-medical fields due to its
efficient protein synthesis ability. Under the legal and regulatory framework, Stanozolol can develop the following types of drugs:
### **1. Medical products**
#### **(1) Treatment of hereditary angioedema (HAE)**
- Stanozolol can effectively reduce the frequency and severity of angioedema attacks.
- Drug form: oral tablets (such as 2mg or 5mg) or injections.
- **Mechanism of action**: By increasing the level of C1 esterase inhibitors, reducing inflammatory responses and edema.
#### **(2) Treatment of osteoporosis**
- Enhance bone density and reduce the risk of fractures.
- Drug form: oral tablets.
- **Mechanism of action**: Improve bone loss by promoting protein metabolism and calcium deposition.
#### **(3) Rehabilitation after severe burns or trauma**
- Used to promote muscle and tissue repair and speed up the recovery process.
- Drug form: injection.
- **Mechanism of action**: Enhance protein synthesis to help patients restore muscle mass and strength.
#### **(4) Treatment of certain types of anemia**
- Promote red blood cell production and improve anemia symptoms.
- Drug form: oral tablets or injections.
#### **(5) Weight management related to wasting diseases**
- Used for rapid weight loss caused by cancer, AIDS or other chronic diseases.
- Drug form: short-term injection therapy.
- **Mechanism of action**: Enhance metabolic rate and protect lean body mass.
### **2. Animal drugs**
#### **(1) Performance enhancers for racehorses, greyhounds and other animals**
- Used to increase muscle mass and strength and improve athletic ability (now banned in many countries).
- Drug form: injection.
#### **(2) Veterinary rehabilitation drugs**
- Promote muscle regeneration and physical recovery in animals recovering from surgery or trauma.
### **3. Non-medical products (high risk of abuse, strictly regulated)**
#### **(1) Sports performance enhancers**
- Improve the strength, endurance and muscle definition of athletes (banned drugs).
- Commonly used in bodybuilding and athletics, but their use has been banned by most sports organizations.
#### **(2) Bodybuilding and body shaping supplements**
- Used to increase muscle hardness and reduce subcutaneous fat.
- The doses commonly abused are much higher than those for medical use, with a high risk of side effects.
### **R&D and restrictions**
1. **Main side effects:**
- **Hepatotoxicity**: Oral form is particularly taxing on the liver.
- **Cardiovascular problems**: Such as high blood pressure and elevated low-density lipoprotein (LDL).
- **Androgenic effects**: May cause hair loss, acne, etc.
- **Endocrine Disruption**: Inhibits endogenous testosterone secretion, leading to hormone imbalance.
2. **Regulatory Restrictions:**
- In many countries, Stanozolol is listed as a controlled drug and must be used with a doctor's prescription.
- The World Anti-Doping Agency (WADA) and most sports organizations prohibit its use in sports.
### **R&D Suggestions**
- **Development Direction:**
- Study low-toxic derivatives to reduce hepatotoxicity and cardiovascular burden.
- Explore local applications (such as patches or ointments) to avoid systemic side effects.
- **Optimize dosage form:**
- Develop long-acting sustained-release preparations to reduce the frequency of medication and improve patient compliance.
**Conclusion:**
Stanozolol is mainly suitable for specific medical treatment areas, but there is also a risk of abuse. Future research and development should
focus on improving drug safety and expanding the scope of legal indications, while strengthening supervision of non-medical use.
