Solid Form Screening And Selection

Solid Form Screening and Selection are vital steps in the development of Active Pharmaceutical Ingredients (APIs). These processes identify and optimize polymorphs, salts, cocrystals, and other solid forms to enhance physical properties such as solubility, dissolution rate, stability, and manufacturability. Selecting the optimal solid form not only improves drug performance but also creates opportunities for new Intellectual Property (IP), ensuring a competitive edge for your pharmaceutical innovations. 

Optimizing solid forms for successful drug development ​

At Solitek, we deliver comprehensive solid form screening services tailored to your drug development program, employing advanced techniques like phase diagrams, high throughput and medium throughput screening, evaporation, cooling, anti-solvent crystallization, thermal and humidity stress, and grinding to optimize drug performance and scalability. 

Through our partnership with XtalPi, leveraging the their AI-powered solid-state virtual screening platform, we now offer a unique, revolutionary virtual cocrystal screen, which computes the interaction between the target API and a large list of pharmaceutically acceptable coformers, ranking them in order of affinity for the API, thereby, improving the efficiency and success rate of the experimental screen. 

Key concepts

Solid form selection plays a pivotal role in overcoming challenges associated with modern drug development:

  • Improved solubility and bioavailability: Giving drugs the best chance to dissolve effectively to achieve the desired therapeutic effect. 
  • Enhanced stability: Selecting solid forms resistant to environmental factors like humidity and temperature. 
  • Optimized manufacturability: Streamlining the production process with solid forms that offer better flow properties and compressibility. 
  • Novel IP opportunities: Identifying unique solid forms such as salts and cocrystals can lead to patentable innovations. 

Our services include the investigation and selection of the optimal solid form for the intended drug formulation, i.e. clinical or preclinical formulation, immediate or sustained release, liquid or solid oral dosage form, etc., to ensure that your product excels in quality and performance. 

We leverage cutting-edge technologies and a systematic approach to deliver precise results: 

  • Polymorph Screening: Exploring a diverse range of conditions likely to be encountered in a development and manufacturing environment, to  Identify and characterize different crystalline forms to find the most stable and effective option. 
  • Salt Selection: Enhancing solubility and stability by evaluating various salt forms. 
  • Cocrystal Screening: Exploring multi-component systems to improve physical and chemical properties. 
  • Dissolution and Solubility Testing: Ensuring optimal release profiles, including immediate release and sustained release formulations. 
  • Full Solid State Characterization and Structural Analysis: Employing techniques like, XPRD, DSC and TGA to thoroughly characterize novel solid forms, and CSP or microelectron diffraction technologies to elucidate the structure of the optimal solid forms for development. 

Solid Form Screening and Selection directly impact multiple aspects of pharmaceutical development, including: 

  • Formulation design: Selecting the optimal solid form to support the development of robust pharmaceutical formulations. 
  • Generation of novel IP: Selection of the right solid form to extend the life cycle of the drug substance, while opening opportunities for alternative drug formulations. 
  • Non-infringing solid forms: Identification of non-infringing solid forms that can be used without breaching existing patent protection. 

By identifying the most suitable solid form, we help pharmaceutical companies reduce development timelines and improve drug performance, positioning products for market success.
