Polymer Selection Science
The foundation of any oral dissolvable strip is its polymer matrix. The choice of film-forming polymer determines dissolution rate, mechanical properties, compound stability, and mucoadhesive characteristics. Key polymers used in ODS formulation include:
- Pullulan: A natural polysaccharide with excellent film-forming properties, rapid dissolution, and neutral taste
- HPMC (Hydroxypropyl methylcellulose): Widely used pharmaceutical excipient with tunable dissolution rates
- PVA (Polyvinyl alcohol): Provides good mechanical strength and flexibility
- Maltodextrin: Rapid-dissolving carbohydrate polymer suitable for fast-dissolve formulations
Active Compound Loading
Loading research compounds into the polymer matrix requires careful optimization to ensure content uniformity, stability, and release characteristics. Factors include compound solubility in the casting solvent, interaction with the polymer matrix, thermal sensitivity during drying, and tendency toward crystallization or aggregation.
Dissolution Rate Engineering
The dissolution rate of an ODS is engineered through polymer molecular weight selection, plasticizer concentration, film thickness, and the inclusion of disintegrants or surfactants. For sublingual delivery, rapid dissolution (under 60 seconds) is typically targeted to maximize mucosal contact time before swallowing.
Stability Optimization
Active compound stability within the strip matrix is ensured through moisture control (packaging with desiccants, moisture-barrier packaging materials), antioxidant incorporation, pH buffering, and appropriate storage conditions. ROEHN's strip products are formulated with these considerations to maintain compound integrity. Explore our full catalog including BPC-157 and Semaglutide.
