  • Who We Are & What We Do

    At Zero483, our aim is to help bridge technical gaps in the pharmaceutical industry by sharing science-based training and comprehensive regulatory resources. We are dedicated to supporting professionals and students entering the field.

    By drawing directly from rigorous global standards—including ICH, Ph. Eur., and ANVISA guidelines on quality and stability—we support our community in achieving better compliance, steady continuous learning, and robust career growth.

    Built by Experts, For the Next Generation
    Started by pharma professionals with years of hands-on experience, including eminent industry scientists, our platform hopes to grow into a simple, powerful network connecting retired experts with the next generation of innovators.

    Master Global Pharma Compliance

    The Regulatory Learning Hub

    Behind every standard set by the FDA, EMA, WHO, ANVISA, and CDSCO are dedicated scientists striving for global patient safety.

    To honor their work and empower the next generation, we created the Pharma Regulatory Learning Hub.

    We combine complex global guidelines with embedded video insights and scenario‑based quizzes. Our goal? To give you centralized, accessible training for real-world compliance challenges—right from your device.

    📚 Course Curriculum

    • Regulatory Foundations: Deep dive into USP <711> & <1092>.
    • FDA Risk Assessment: Compliance for IR, ER, and DR dosage forms.
    • Discriminating Ability: Case studies on API particle size and manufacturing errors.
    • Demonstrating Equivalence: f2 Similarity Factor, Bootstrapping, and MSD.

    2. ICH Q1 Series: Stability Testing

    Navigate global climatic zones and study designs.

    • ICH Q1A(R2): General conditions, significant change, and shelf-life.
    • ICH Q1B: Confirmatory photostability and illumination standards.
    • ICH Q1C-Q1F: New dosage forms, bracketing vs. matrixing, and climatic zones.

    3. ICH Q2 & Q14: Analytical Validation

    Modernize your approach to Quality by Design (QbD).

    • ICH Q2(R2): Validation fundamentals (specificity, robustness, LOQ).
    • ICH Q14: The modern combined lifecycle approach and Analytical Target Profile (ATP).

    4. ICH Q3 Series: Impurities

    Ensure product safety through risk-based profiling.

    • ICH Q3A & Q3B: Thresholds for new drug substances and products.
    • ICH Q3C: Residual Solvents (Classes 1-3) & PDE calculations.
    • ICH Q3D: Elemental Impurities and route-specific risk.
    • ICH Q3E: Extractables & Leachables (AET and migration risks).

    5. Nitrosamine Impurities

    Tackle critical safety challenges with actionable mitigation.

    • Risk Mitigation: The mandatory 3-step process (Assess, Test, Mitigate).
    • Root Cause Analysis: Vulnerable amines and packaging risks.
    • Thresholds: Acceptable Intakes (AI) and Less Than Lifetime (LTL) limits.

    6. Pediatric Drug Development

    Optimize formulations for vulnerable populations.

    • Excipient Optimization: Maximum Daily Intake (MDI) vs. Acceptable Daily Intake (ADI).
    • Case Studies: Managing challenges like PG overexposure and SBECD in immature kidneys.
    • Global Alignment: Harmonizing FDA’s iPSP and EMA’s PIP.
