Detailed Instructions for Medical Grade Sterile Water for Injection (National Drug Approval Number) - Precautions - Adverse Reactions - Usage and Dosage

Medical grade sterile water for injection (Sterile Water for Injection, USP) is a commonly used basic medication in healthcare. It is sterile water used for preparing drug solutions, undergoing strict sterilization and filtration processes to ensure it is free from any microbial contamination, making it suitable for injection or intravenous infusion. It serves as a solvent or diluent for various drug formulations and is widely used in medical institutions such as hospitals and clinics.

I. Basic Overview of Medical Grade Sterile Water for Injection

Definition: Medical grade sterile water for injection is water specifically intended for injection or intravenous infusion. It must undergo rigorous sterilization to ensure it is free from contamination, guaranteeing that it does not cause any infection or adverse reactions in patients during medical applications.

Characteristics:

1. Sterility: Sterile water for injection must undergo high-temperature sterilization to ensure it is free from any microbial, bacterial, fungal, or other biological contamination.

2. No Additives: This water contains no drugs or solvent additives, and its pH level, inorganic salts, etc., should be within suitable ranges to avoid any adverse reactions in the human body.

3. Purity: The purity of injection water is extremely high, with almost no dissolved organic or inorganic substances, and very low levels of ions and electrolytes.

4. Suitable for Injection: Primarily used for dissolving or diluting drugs for intravenous injection, intramuscular injection, subcutaneous injection, etc.

II. Functions of Medical Grade Sterile Water for Injection

The functions of medical grade sterile water for injection are primarily reflected in its role as a solvent or diluent, helping other drugs dissolve, dilute, or mix effectively to make them suitable for injection or infusion.

1. Solvent Function:

Medical grade sterile water for injection is an ideal solvent in many drug formulations. For example, certain antibiotics, hormonal drugs, chemotherapy drugs, etc., require administration via injection or infusion. When preparing these drugs, sterile water for injection is used as a solvent. As a pure solvent, water effectively helps these drugs dissolve completely during injection, ensuring the proper efficacy of the medication.

2. Dilution Function:

Drugs often require dosage adjustments based on the patient's specific conditions (e.g., age, weight, condition). Medical grade sterile water for injection plays a role in diluting drugs during this process. Through dilution, the concentration of the drug is adjusted to ensure the dosage is suitable for the patient's needs and to reduce adverse reactions.

3. Irrigation Function:

Medical grade sterile water for injection is commonly used for irrigation purposes in medical procedures. For example, during certain surgical procedures, doctors use sterile water for injection to irrigate wounds or incisions to remove dirt, bacteria, or foreign objects. It is also commonly used to flush intravenous injection lines to keep them clear.

4. Carrier Function:

In some cases, medical grade sterile water for injection can also serve as a carrier for drugs, assisting in the delivery of drugs during injection. For example, during intravenous injection, water helps drugs quickly enter the bloodstream, ensuring effective absorption.

III. Usage Methods of Medical Grade Sterile Water for Injection

Medical grade sterile water for injection itself contains no active pharmaceutical ingredients, so its usage is typically related to the drug formulations it is used to prepare. Below are several common usage methods:

1. Dissolving Drugs:

In clinical settings, medical grade sterile water for injection is commonly used to dissolve or dilute drugs intended for injection. Drugs such as antibiotics and hormonal drugs often require dissolution in injection water before they can be injected into the body. The dosage should be used correctly according to the drug's instructions or the doctor's prescription.

2. Diluting Drug Solutions:

For certain drugs (e.g., some chemotherapy drugs, potent drugs), dilution is often necessary to reduce concentration and avoid irritation or excessive drug reactions in patients. Medical grade sterile water for injection plays a crucial role in this regard. Doctors will adjust the amount of water and drug used based on the drug's instructions and the patient's actual condition.

3. Intravenous Infusion:

Medical grade sterile water for injection is often used as part of intravenous infusions, mixed with drugs for intravenous drip. In this case, the injection water helps transport the drug quickly through the bloodstream, ensuring timely efficacy.

4. Irrigation of Wounds and Lines:

Medical grade sterile water for injection is also used for cleaning wounds, incisions, and flushing infusion lines after certain surgeries. It effectively removes debris from wounds, reduces the risk of infection, and maintains the cleanliness and patency of medical devices.

IV. Usage and Dosage of Medical Grade Sterile Water for Injection

The usage and dosage of medical grade sterile water for injection depend on different clinical needs and are typically determined by doctors or pharmacists based on the patient's specific condition.

1. Drug Dissolution and Dilution:

During administration, doctors will specify the amount of injection water needed based on the drug's properties and the patient's condition. For example, some powdered drugs require mixing with a certain amount of medical grade sterile water for injection to dissolve before injection. The specific amount for dissolution is usually clearly stated in the drug's instructions.

2. Intravenous Injection Fluids:

If medical grade sterile water for injection is used for intravenous infusion, it typically needs to be combined with drugs to form a compound fluid. Based on factors such as the patient's age, weight, and condition, the doctor will determine the appropriate dosage and flow rate to ensure effective delivery of the drug.

3. Irrigation and Cleaning:

In some surgeries or wound treatments, medical grade sterile water for injection is commonly used for irrigating wounds or cleaning lines. The amount used depends on the size of the wound or the area needing irrigation, generally aiming to fully clean and remove foreign objects or blood clots.

4. Volume of Infusion Fluids:

During intravenous infusion, the amount of medical grade sterile water for injection can range from tens to hundreds of milliliters, with the specific volume adjusted based on the concentration of the drug being infused, the infusion time, and the patient's fluid needs.
