Proactive Problem-Solving in Formulation and Process Design

Anticipating challenges before they escalate is a hallmark of successful topical product development. At DDL, our project teams apply a proactive, solutions-oriented mindset from the earliest phases of formulation through scale-up and clinical manufacturing. This approach is rooted in our collective experience working with a wide range of APIs, excipients, and dosage forms—enabling us to identify potential risks and mitigation strategies early in the project timeline.

Common issues addressed through proactive problem-solving include:

1. API Solubility and Stability: Early pre-formulation studies are designed to assess solubility across multiple solvent systems and screen for degradation pathways under various environmental conditions.
2. Physical Stability and Viscosity Drift: We conduct accelerated and real-time stability studies using ICH protocols, closely monitoring for changes in phase separation, viscosity, and appearance that could impact product quality or patient acceptability.
3. Scale-up Challenges: Pilot-scale batches are manufactured under conditions that simulate clinical supply production, allowing for identification of process-critical parameters and potential bottlenecks before moving to cGMP clinical lots.

For example, when supporting a client with a high-potency corticosteroid cream, our team identified a risk of API crystallization under low-temperature storage. By reformulating with optimized co-solvent and surfactant systems, we helped the client achieve both regulatory-required stability and desirable product aesthetics.

This proactive problem-solving framework is designed to reduce surprises during late-stage development and to keep topical product development innovations firmly focused on program goals.
