Proprietary Tools

Optimized protocols and internal know-how to accelerate decisions and reduce uncertainty

Solid-state development and preclinical formulation services are critical for the development of new drugs and the improvement of existing ones. Regulatory authorities require tight controls on novel drug candidates prior to their progression into clinical trials involving human subjects.

In this context, engaging a specialized company like Solitek Pharma, with its extensive experience and proven track record, provides an initial assurance for minimizing operational risks, reducing project timelines, optimizing investment, and accessing expert knowledge and guidance at every stage of the optimization process, in every challenge.

We deliver flexible and high-quality solutions to pharmaceutical, biotechnology, and generic drug companies, supporting the transition from late-stage drug discovery through early clinical development and late-phase manufacturing. Our expertise ensures optimisation and control of the solid state and physical properties of active pharmaceutical ingredients.

Quality, Innovation and Safety in Solid Form Phases

Maybe you’ve come here because you know that:

Every month lost in the preclinical development delays trials, investment opportunities, and key decisions.
A poor selection of solid form can ruin years of work.
Unoptimized crystallization processes can lead to increased variability, operational setbacks, and a lack of internal confidence.
Poorly documented solid state decisions put the drug at regulatory risk from the start
Inconsistent results lead to delayed decisions and the loss of your partners’ trust
Without a robust solid form strategy, you are increasing the risk of selecting an unsuitable polymorph, salt, or cocrystal.
Investors, partners and management expect clear and fast, evidence-based decisions, not uncertainty.
Your project is advancing, but you're not taking advantage of new intellectual property opportunities.

At Solitek Pharma, we work to ensure that none of this happens in the development of your program.
