title: Polymer strip films as a robust, surfactant-free platform for delivery of BCS Class II drug nanoparticles.
abstract: The robustness of the polymer strip film platform to successfully deliver a variety of BCS Class II drug nanoparticles without the need for surfactant while retaining positive characteristics such as nanoparticle redispersibility and fast dissolution is demonstrated. Fenofibrate (FNB), griseofulvin (GF), naproxen (NPX), phenylbutazone (PB), and azodicarbonamide (AZD) were considered as model poorly water-soluble drugs. Their aqueous nanosuspensions, produced via wet stirred media milling, were mixed with hydroxypropyl methylcellulose solution containing glycerin as plasticizer, followed by casting and drying to form films. For the purpose of comparison, sodium dodecyl sulfate (SDS) was used as surfactant, but was found to be unnecessary for achieving fast dissolution (t80 between 18 and 28 min) for all five drugs. Interestingly, SDS was required for the full recovery of nanoparticles for PB, yet lack of it did not impact the dissolution. Interactions between drug and polymer were investigated with FTIR spectroscopy whereas drug crystallinity within the film was investigated via Raman spectroscopy. Films for all drugs, even for very small samples, exhibited excellent content uniformity (RSD <4%) regardless of use of surfactant. Overall, these results demonstrate the novelty and robustness of the polymer strip film platform for fast release of poorly water-soluble drugs without requiring any surfactants.
