Product Introduction

#### 1. Overview

Hepius brand T4 (Levothyroxine) is a widely used thyroid hormone replacement drug, mainly used to treat hypothyroidism. Thyroid hormone plays a vital role in the human body, regulating multiple physiological processes such as metabolism, growth and development, and body temperature. When the thyroid gland cannot produce enough thyroid hormone, Levothyroxine, as an exogenous hormone substitute, can effectively supplement the lack of thyroid hormone in the body and help patients restore normal physiological functions.

#### 2. Pharmacological effects of Levothyroxine

Levothyroxine is a synthetic form of the thyroid hormone T4 (tetraiodothyronine), and its structure is exactly the same as T4 produced naturally by the human body. T4 is converted into T3 (triiodothyronine) in the body through the action of deiodinase. T3 is the active form of thyroid hormone, which can bind to thyroid hormone receptors in the cell nucleus, regulate gene expression, and thus affect the metabolic activity of cells.

1. **Metabolic regulation**: Levothyroxine helps maintain normal energy levels by increasing the basal metabolic rate, promoting the metabolism of proteins, fats and carbohydrates.

2. **Growth and development**: For children and adolescents, thyroid hormones are essential for the development of the bones and nervous system. Levothyroxine can promote normal growth and development and prevent developmental delays caused by hypothyroidism.

3. **Cardiovascular system**: Thyroid hormones have a direct effect on heart function, can increase heart rate and cardiac output, and improve blood circulation.

4. **Nervous system**: Thyroid hormones also have an important effect on brain function, which can improve cognitive function, mood and mental state.

- **High stability**: The tablets are stable at room temperature and easy to store and carry.

2. **Liquid dosage form**:

- **Advantages**:

- **Suitable for patients with dysphagia**: For children, the elderly or patients with dysphagia, liquid dosage forms are easier to take.

- **Rapid absorption**: Liquid dosage forms are usually absorbed faster than tablets and can exert their effects faster.

- **Flexible dosage**: Liquid dosage forms can accurately control the dosage by adjusting the dosage, which is suitable for patients who need to adjust the dosage frequently.

3. **Special dosage form for children**:

- **Advantages**:

- **Appropriate dosage**: Special dosage forms for children usually have a smaller dosage, which is suitable for the physiological characteristics of children.

- **Good taste**: In order to increase children's medication compliance, Hepius brand children's dosage forms usually add appropriate amounts of flavoring agents to improve the taste.

- **High safety**: Children's dosage forms have undergone rigorous clinical trials to ensure safety for children.

4. **Sustained release dosage form**:

- **Advantages**:

- **Long-acting effect**: Sustained release dosage forms can slowly release drugs in the body, maintain stable blood drug concentrations, and reduce the number of medications.

- **Reduce side effects**: Due to the slow release rate of drugs, sustained release dosage forms can reduce side effects caused by fluctuations in blood drug concentrations, such as palpitations, anxiety, etc.

#### 4. Clinical application of Hepius brand T4

1. **Hypothyroidism**:

- Levothyroxine is the first choice for the treatment of hypothyroidism. By supplementing exogenous thyroid hormones, patients can restore normal metabolism and physiological functions.

- **Advantages**: Hepius brand Levothyroxine has high purity and high bioavailability, which can quickly and effectively relieve the symptoms of hypothyroidism, such as fatigue, weight gain, dry skin, etc.

2. **Postoperative replacement therapy for thyroid cancer**:

- After thyroid cancer surgery, patients usually need to take Levothyroxine to replace thyroid hormones and inhibit the secretion of thyroid stimulating hormone (TSH) to prevent the recurrence of cancer cells.

- **Advantages**: Hepius brand Levothyroxine can provide stable hormone levels to help patients maintain normal physiological state while reducing the risk of cancer recurrence.

3. **Congenital hypothyroidism**:

- For newborns and infants, congenital hypothyroidism may cause serious developmental disorders. Early treatment with Levothyroxine can prevent mental retardation and growth retardation.

- **Advantages**: Hepius brand children's special dosage form has accurate dosage and high safety, which is suitable for long-term use by infants and young children.

4. **Hypothyroidism during pregnancy**:

- Hypothyroidism during pregnancy may have adverse effects on fetal development. Levothyroxine is safe to use during pregnancy and can effectively maintain the thyroid hormone levels of the mother and fetus.

- **Advantages**: Hepius brand Levothyroxine is safe to use during pregnancy and can effectively prevent the negative effects of hypothyroidism during pregnancy on the fetus.
