Nail Permeation Testing
Assessing Penetration into Keratinized Structures
MedPharm offers specialized hard tissue and nail permeation testing to evaluate drug absorption, retention, and diffusion in keratinized structures, such as the nail plate, calloused skin, and hyperkeratotic lesions. These studies provide critical insights for the development of topical and transungual therapies targeting conditions like onychomycosis, psoriasis, and nail dystrophies.
Our validated ex vivo nail and keratinized tissue models help optimize penetration enhancer strategies, formulation selection, and treatment efficacy, ensuring that your drug achieves maximum therapeutic impact.
Why Hard Tissue & Nail Permeation Testing Matters
Critical for Transungual & Hard Tissue Drug Development: Helps design effective treatments for onychomycosis, nail psoriasis, and hyperkeratotic disorders.
Optimizes Penetration Enhancement Strategies: Evaluates the impact of formulation excipients, chemical enhancers, and mechanical treatments.
Regulatory & Bioequivalence Support: Provides FDA, EMA, and ICH-compliant permeation data to support drug approvals and generic equivalence studies.
Reduces Clinical Risk: Predicts in vivo drug penetration to optimize dose and delivery strategies before clinical trials.
How Hard Tissue & Nail Permeation Testing Works
MedPharm employs validated in vitro and ex vivo nail penetration models using human and porcine nails, keratinized tissue, and specialized diffusion cells to assess drug transport dynamics.
- Test Formulation Application: A known quantity of the drug is applied to nail plates or thickened keratinized tissue.
- Permeation & Diffusion Analysis: The drug penetrates and diffuses through the keratinized structure over time.
- Timed Sample Collection: Receptor solution samples are collected at regular intervals to measure drug permeation.
- Quantification via HPLC/LC-MS: Drug concentrations in tissue and receptor solutions are analyzed to generate permeation profiles.
