Transdermal
Testing Systems
GMP-certified analysis and quality control for Transdermal Drug Delivery Systems (TDDS), ensuring regulatory compliance and dosage precision.
Mastering the Interface
Transdermal patches require a unique fusion of adhesive science and pharmaceutical precision. At BrownBiology Laboratory, we provide specialized QC programs mapping the entire lifecycle of transdermal products.
Our laboratories are equipped with dedicated dissolution apparatus and skin permeation modules to execute complex in-vitro release (IVRT) and permeation (IVPT) studies, alongside rigorous physical testing for patch integrity.

Core Technical Framework
Comprehensive testing protocols for transdermal drug delivery excellence.
1Physical & Adhesion Analysis
Critical assessment of peel adhesion, tack properties, and shear strength to ensure reliable patch performance and patient wearability.
2In-vitro Release (IVRT)
Standardized drug release profiles using USP Apparatus 5 (Paddle over Disk), 6 (Cylinder), or 7 (Reciprocating Holder) across all product formats.
3Permeation Studies (IVPT)
Simulating drug delivery through skin barriers using Franz diffusion cells to quantify biological availability and absorption kinetics.
4Purity & Degradation
Monitoring of related substances and potential degradation pathways through high-resolution HPLC-UV/MS modules during stability trials.
Integrated Product Support
We support transdermal programs from early stage method development and validation through to long-term stability monitoring and late-stage clinical batch release. Our data packages are fully structured for IND/NDA and market authorization dossiers.
