The oral thin film can carry various active pharmaceutical ingredients (APIs), but taking high doses of APIs is challenging due to the limitation of dosage form size. Therefore, APIs with poor solubility pose a significant challenge to the formulation development of oral thin films. CD Formulation has a variety of solubilizing technologies for poorly soluble drugs, turning poorly soluble drugs into solid dispersions or nanoparticles to increase the drug loading capacity of the oral thin film.

As a relatively new dosage form for the oral route of administration, the oral thin film is postage stamp-sized strips of thin polymeric films formulated to disintegrate or dissolve almost instantaneously when placed onto the tongue. The drug in the oral thin film is absorbed through the oral mucosa, which makes drugs enter the systemic circulation without undergoing first-pass hepatic metabolism.
In the formulation development of oral thin film, our solubilization technology for poorly soluble drugs is focused on optimizing the solid form of API to improve drug solubility. With our professional crystal innovation technology team and oral thin film preparation development team, CD Formulation provides tailored systematic solutions for poorly soluble drugs to help achieve precise breakthroughs in oral thin film. Our solubilization technologies for poorly soluble drugs include:
Solid dispersion is a kind of dispersion system that exists in solid form, which evenly disperses the drug in the carrier in a highly dispersed state such as molecule, amorphous state, and microcrystal state. Solid dispersion can increase the dissolution of insoluble drugs, improve bioavailability, delay drug release, and increase drug stability, providing more options for oral thin film formulation development.

Oral thin film is unsuitable for delivering drugs with poor water solubility because drugs with poor water solubility have poor oral mucosa drug absorption. Therefore, drugs with poor water solubility are a real challenge in developing oral thin films. Nanosuspensions, as one of the nanoscience approaches, have become a promising development tool for improving the water solubility, dissolution rate and oral bioavailability of poorly water-soluble drugs by reducing the particle size in the oral thin film pharmaceutical industry.

Results: Absorption of the drug and its therapeutic effectiveness are affected by solubility, which is a significant physicochemical factor. Poor aqueous solubility can lead to failure in the formulation development process. One of the most promising and efficient techniques for solubility enhancement is solid dispersion formulation. Solid dispersion can be classified as simple eutectic mixtures, solid solutions, glass solutions and glass suspensions, amorphous precipitation in a crystalline carrier, and compound or complex formations.
