Our Quality Control & Assurance Framework
At Zeptide Pharma, our Quality infrastructure is built on a rigorous system of checks and balances. Our Quality Control (QC) team spearheads the scientific testing and analytical verification of every product, while our Quality Assurance (QA) team provides independent oversight of all processes and documentation.
Together, they ensure that every medication leaving our facility adheres to the following cGMP-mandated QC processes:
1. Stringent Incoming Material Verification
Zeptide Pharma does not rely solely on vendor documentation. We independently verify all raw materials before they enter our production stream:
- Identity Testing: We utilize advanced analytical tools (such as FTIR spectroscopy, Raman spectroscopy, or HPLC) to chemically confirm that each Active Pharmaceutical Ingredient (API) exactly matches its label.
- Purity and Potency: All APIs are tested for moisture content, heavy metals, and residual solvents to ensure compliance with USP monograph standards.
- Component Inspection: We perform rigorous visual and physical testing on vials, stoppers, and seals to eliminate defects or bioburden prior to production.
2. Real-Time In-Process Testing
Our QC team monitors production in real-time to ensure absolute precision during the compounding process:
- Weight/Volume Verification: We perform periodic checks on all filling lines to ensure dispensing accuracy (e.g., verifying a precise 10.5mL fill for a 10mL vial).
- Physiological Parameters: For IV and ophthalmic solutions, we test pH and osmolality mid-batch to ensure patient comfort and product stability.
- Visual Vigilance: We maintain constant monitoring for particulate matter ("floaters") or glass defects throughout the filling stage.
3. Advanced Finished Product Analytical Testing
No batch is released to the public without comprehensive post-production testing:
- Potency Assay: We utilize High-Performance Liquid Chromatography (HPLC) to confirm that every drug is at the exact intended strength (typically within the narrow 90%–110% range).
- Purity Profiling: We screen for degradation products or related substances that may have formed during compounding.
- Particulate Matter Analysis (USP <788>): We use light-obscuration and microscopic methods to ensure that all injectables are free of dust, plastic, or glass particles.
4. Comprehensive Microbiological Quality Control
As a core pillar of our safety program, our microbiology lab performs intensive testing on every lot:
- Sterility Testing (USP <71>): We conduct 14-day incubations across multiple growth media to ensure the complete absence of aerobic and anaerobic bacteria and fungi.
- Endotoxin Testing (USP <85>): We utilize the Limulus Amebocyte Lysate (LAL) test to ensure all products are non-pyrogenic and safe for injection.
- Growth Promotion: We verify every batch of our testing media to ensure it supports microbial growth, eliminating the risk of false-negative results.
5. Data-Driven Stability and Expiration Dating
Zeptide Pharma rejects "default" dating. Our expiration dates are established through rigorous scientific study:
- Stability Indicating Assays: We test our products at specific intervals (Day 30, 60, 90, etc.) under varying temperature and light conditions to determine the true shelf life.
- Photostability & Integrity: We evaluate the need for light-protective packaging and perform Container Closure Integrity (CCI) testing to ensure the sterile seal remains intact through the product's end-of-life.
6. Environmental Monitoring (EM) & Trend Analysis
Our QC department provides the analytical oversight for our cleanroom surveillance:
- Proactive Trending: We review EM data monthly and quarterly to identify environmental shifts before they reach "Action Levels," ensuring our cleanrooms remain under control.
- Organism Identification: When a microbe is detected, we perform genus and species identification to pinpoint the source and prevent recurrence.
7. Rigorous Analytical Method Validation
We ensure our "math and machines" are beyond reproach:
- Method Validation: Zeptide Pharma validates every test method for every specific drug. This ensures that the drug’s unique chemistry does not interfere with our ability to detect potency issues or microbial contamination.
8. Retain Sample Management
We maintain a comprehensive "Retain Library" for long-term accountability:
- Reserve Samples: We store representative samples from every batch in climate-controlled environments. This allows us to perform retrospective testing at any time during the product's shelf life to confirm continued quality.
The Zeptide Quality Balance
- Our QC Team ("The Doers"): Responsible for executing the science—sampling, testing, running the HPLC, and generating raw lab data.
- Our QA Team ("The Reviewers"): Responsible for the final safeguard—independently reviewing QC lab reports, verifying staff training, and providing the final "Release" signature that authorizes a batch for shipment.
