📄 About This Publication
This stability study evaluated the physicochemical and microbiological stability of Constac granules — the patented Ayurvedic laxative formulation developed at Healing Hands Clinic — under real-time and accelerated storage conditions following ICH (International Council for Harmonisation) guidelines Q1A(R2).
Parameters evaluated included physical appearance, colour, odour, hygroscopicity, flow properties (angle of repose, bulk density), moisture content, active constituent assay, pH, disintegration time, and microbial limit testing.
The study confirmed that Constac granules maintained their physicochemical integrity and microbiological safety across all storage conditions tested, supporting the assignment of a defined shelf-life and appropriate storage recommendations for commercial packaging and distribution.
✓ Key Findings & Clinical Significance
✔ ICH Q1A(R2) compliant stability protocol
✔ Real-time and accelerated storage conditions tested
✔ Parameters: appearance, moisture, active assay, flow, microbial limits
✔ Supports commercial shelf-life assignment for Constac granules
✔ Essential regulatory data for Ayurvedic product registration

❓ Frequently Asked Questions
Q: Why is a stability study important for herbal formulations?
Stability studies confirm that a herbal product retains its potency, safety, and physical form throughout its assigned shelf life — critical for both regulatory approval and patient safety.
Q: What conditions were used in this stability study?
The study used ICH-recommended accelerated conditions (40°C/75% RH) and real-time conditions (25°C/60% RH) to predict long-term product stability.
Q: What is the shelf life of Constac granules?
The assigned shelf life is detailed in the published article based on stability data collected across the study duration.
