To ensure proper management and traceability of samples undergoing stability studies in a pharmaceutical setting in Surat, Gujarat, India, the labels on these samples must contain specific information. These labels are critical for identifying the samples, their storage conditions, and the time points for analysis. Here’s a breakdown of the key elements that should be included on stability sample labels:
Essential Information:
* Product Name: The name of the pharmaceutical product under study.
* Batch Number: The specific batch number of the product being tested.
* Sample Identifier/Code: A unique code assigned to each individual sample within the batch and study. This helps in tracking specific containers.
* Stability Condition: Clearly indicate the storage condition under which the sample is being held (e.g., 25°C/60% RH, 40°C/75% RH, 5°C, -20°C, photostability). Use standard abbreviations for clarity.
* Date In (Incubation Date): The date when the sample was placed in the stability chamber.
* Time Point/Pull Point: The scheduled time point for sample withdrawal and analysis (e.g., Initial, 3 Months, 6 Months, 12 Months).
* Storage Location/Chamber Number: Identification of the specific stability chamber where the sample is stored.
* Orientation (if applicable): If the sample needs to be stored in a specific orientation (e.g., upright, inverted, horizontal), this should be clearly indicated.
Additional Information (as needed):
* Strength: The strength or potency of the pharmaceutical product (e.g., 500mg).
* Dosage Form: The form of the product (e.g., Tablets, Capsules, Solution).
* Pack Size: The size of the packaging being tested (e.g., 30 count bottle).
* Analysis to be Performed: If different tests are scheduled for different time points, a brief indication of the primary analysis might be helpful (e.g., Assay, Dissolution).
* “Reference Standard” or “Test Sample”: To differentiate between the drug product sample and any reference standards included in the study.
Labeling Best Practices:
* Durability: Use labels that can withstand the storage conditions (temperature, humidity) without fading, peeling, or becoming brittle.
* Legibility: Ensure all information is printed clearly and is easy to read. Use a font size that is not too small.
* Secure Attachment: Affix labels securely to the sample containers to prevent them from falling off during handling or storage.
* Color Coding (Optional): Some companies use color-coded labels to quickly identify different storage conditions or time points. If used, ensure a clear legend explains the color scheme.
* Consistency: Maintain a consistent labeling format across all stability samples within a study and across different studies.
* Uniqueness: Ensure that each sample has a unique identifier to avoid confusion.
* Regulatory Compliance: While the specific requirements might vary slightly based on local regulations (e.g., adherence to Indian pharmacopeia and CDSCO guidelines), the information above generally aligns with good laboratory practices and international guidelines like ICH.
Example Label Format:
A typical stability sample label might look like this:
Product: [Product Name]
Batch No: [Batch Number]
Sample ID: [Unique Sample Code]
Condition: [Storage Condition]
Date In: [DD-MMM-YYYY]
Time Point: [e.g., 3M]
Location: [Chamber Number]
Orientation: [if applicable]

It’s crucial to have a Standard Operating Procedure (SOP) in place that details the exact requirements for labeling stability samples within your pharmaceutical quality system in Surat. This SOP should specify the information to be included, the format of the labels, and the responsibilities of the personnel involved in labeling.
