Nabota®, a highly purified Botulinum Toxin Type A product, requires meticulous preparation to ensure its intended performance and patient safety. Understanding the precise steps for mixing Nabota is fundamental for every practitioner utilizing this treatment.

This guide provides a practical overview of the Nabota reconstitution process for medical professionals.

This information is intended for trained medical professionals. Always consult the product’s full instructions for complete details and guidance relevant to the specific lot and preparation instructions provided by the manufacturer. This content is not a substitute for formal hands-on training.

Understanding Nabota® (Botulinum Toxin Type A)

Nabota® is a 900 kDa botulinum toxin type A complex derived from wild-type Clostridium botulinum Hall A strain. It undergoes a purification process designed to yield a high-purity product, often noted for its single 900 kDa protein peak. It is supplied as a lyophilized (freeze-dried) powder in a single-use vial, requiring reconstitution with sterile saline before administration.

Why Proper Reconstitution is Essential

Meticulous reconstitution is not merely a procedural step; it’s fundamental for ensuring patient safety and treatment efficacy:

• Dosage Accuracy: Ensuring the correct volume of diluent is added directly determines the final concentration (Units/mL). Precise measurement is essential to deliver the intended number of units, crucial for achieving the desired clinical effect and minimizing risks associated with incorrect dosing.
• Sterility: Maintaining strict aseptic technique throughout reconstitution prevents microbial contamination of the solution, which could lead to serious injection-site infections.
• Efficacy: Proper, gentle dissolution ensures the lyophilized powder is fully dispersed and the active toxin is evenly distributed in the solution, allowing it to work effectively. Gentle handling is key to maintain product integrity.
• Safety: Minimizes errors in preparation that could lead to suboptimal treatment outcomes (e.g., under-dosing) or adverse events (e.g., due to contamination or incorrect concentration).

Selecting the Appropriate Diluent and Volume

The standard and recommended diluent for Nabota® reconstitution is sterile, preservative-free 0.9% Sodium Chloride for Injection (normal saline). Using any other diluent is not recommended unless specifically stated in the manufacturer’s IFU.

The volume of saline added to the vial determines the final concentration of the Nabota® solution (Units per mL). The desired concentration depends on the specific treatment area and the injector’s preferred technique. A more concentrated solution (less diluent) is often used for smaller muscles or areas requiring precise control, while a more dilute solution (more diluent) might be used for larger muscles or broader diffusion. Always refer to the Nabota® IFU and your specific training for recommended dilution volumes for different indications.

The relationship between diluent volume and concentration is: 1500 Units / (mL of Saline Added) = Concentration in Units/mL (Note: Some Nabota presentations may contain 100 Units per vial; always verify the total units in the vial being used and adapt the calculation accordingly). Practitioners calculate the volume of diluent based on the target concentration for their injection protocol (e.g., to achieve 10 Units/0.1mL, which is 100 Units/mL, you would add 15mL of saline to a 1500 Unit vial, or 1mL to a 100 Unit vial).

Step-by-Step Nabota® Reconstitution Procedure

Perform these steps using strict aseptic technique:

1. Gather Supplies: Collect all necessary items: one vial of Nabota® (confirm expiry date is valid), sterile 0.9% Sodium Chloride for Injection, appropriate sterile syringes (e.g., 1mL tuberculin syringe for drawing up reconstituted solution), sterile needles (e.g., 21G-23G for drawing saline, finer gauge for injection), alcohol swabs, sterile gloves.
2. Prepare Aseptically: Wash hands thoroughly and put on sterile gloves. Clean a workspace to create a sterile field, free from clutter. Clean the rubber stopper of the Nabota® vial and the saline vial (or ampoule neck) with alcohol swabs and allow them to dry completely.
3. Add the Diluent: Using a new, sterile syringe and needle, withdraw the recommended volume of sterile saline. The exact volume of saline to add per vial depends on the desired final concentration (Units/mL) and the unit size of the Nabota vial (100 IU or 200 IU). Consult the Nabota IFU for the correct volume of diluent for standard reconstitution and recommended concentrations for different clinical uses.
4. Mix Gently: After adding the saline, remove the syringe and needle. Gently swirl or slowly invert the vial until the lyophilized powder is completely dissolved. Do NOT shake the vial vigorously, as shaking can damage the toxin molecule and reduce potency. The solution should become clear and homogeneous.
5. Inspect Solution: Before drawing up the solution for injection, visually inspect the vial to ensure the reconstituted solution is clear, colorless, and free of any visible particles. Do not use if it is cloudy or contains particulates.
6. Label Vial: Immediately after reconstitution, clearly label the Nabota® vial with the date, time of reconstitution, and the final concentration (Units/mL).
7. Store Reconstituted Solution: Store the reconstituted Nabota® solution in a refrigerator at 2°C to 8°C (36°F to 46°F).

Maintaining Sterility During Preparation

Strict aseptic technique is critical throughout the mixing process to prevent microbial contamination. This includes:

• Performing thorough hand washing before gloving.
• Wearing sterile gloves.
• Using only sterile, single-use syringes, needles, and diluent.
• Cleaning vial stoppers meticulously with antiseptic swabs.
• Maintaining a clean workspace, free from clutter.
• Opening product packaging only immediately before use.

Selecting Diluent and Volume

As noted, the appropriate diluent is sterile 0.9% Sodium Chloride (Saline) for Injection. The volume of saline added determines the final concentration of the Nabota® solution in Units per milliliter (IU/mL). Different clinical applications may utilize different concentrations. Always consult the Nabota IFU for specific guidance on reconstitution volumes for the vial size you are using and recommended concentrations for different indications or techniques. Accurate measurement of the diluent volume is critical for ensuring the final concentration is correct.

Storage and Shelf Life

Proper storage is crucial for maintaining Nabota’s effectiveness:

• Before Reconstitution: Store lyophilized Nabota vials according to manufacturer instructions (typically refrigeration at 2-8°C).
• After Reconstitution: Reconstituted Nabota has a limited shelf life. It should be stored under refrigeration (2-8°C) and typically used within a specific timeframe after reconstitution (often 24 hours, but always verify this duration in the Nabota IFU). Do not freeze reconstituted solution.

Accurate labeling with the date and time of reconstitution is essential to ensure the product is used within its recommended shelf life.

Common Issues and Troubleshooting

While reconstitution is straightforward, be aware of potential issues:

• Cloudiness or Particles: If the solution is not clear or contains visible particles after mixing, do not use it. This indicates potential product issue or contamination.
• Foaming: Excessive shaking during mixing can cause foaming. If this occurs, let the vial sit upright for a few minutes to allow the bubbles to settle before drawing up the solution.
• Measurement Errors: Inaccurate measurement of the diluent volume will result in an incorrect final concentration. Always use properly marked syringes and double-check measurements.

Adhering to Manufacturer Guidelines and Regulatory Standards

Ensuring the safety and efficacy of Nabota treatments relies heavily on adhering strictly to the manufacturer’s instructions for reconstitution, storage, handling, and administration as provided in the product’s instructions. Following these guidelines, helps guarantee patient safety and predictable results. Manufacturer guidelines cover everything from the correct type and volume of diluent to storage after mixing and recommended injection protocols.
