Frequently Asked Questions

Still have questions?

Contact Us

• What are lipid-based formulations?

  Lipid-based formulations (LBF) are lipid-based drug delivery systems, which aim to improve the solubility, absorption, and bioavailability of poorly water-soluble drugs. LBFs typically consist of lipids, surfactants, co-solvents and sometimes co-surfactants. Surfactants are added to LBF to enhance drug solubility by reducing the interfacial tension between the drug and the surrounding aqueous environment. They also help form stable emulsions or micelles, which improves drug absorption. Co-solvents are used to increase the solubility of lipophilic drugs in the lipid phase, which helps dissolve the drug and maintain its solubility during formulation and storage. Co-surfactants are sometimes added to LBF to further stabilize the formulation and enhance drug dissolution. Currently, LBF can be formulated as emulsions, self-emulsifying drug delivery systems (SEDDS), self-microemulsifying drug delivery systems (SMEDDS), or solid lipid nanoparticles (SLN). These formulations can improve drug dissolution, increase drug absorption through the lymphatic system, and increase oral bioavailability.

• How do you customize lipid formulations for different drug types?

  Each formulation is designed based on the physicochemical properties of your drug, such as solubility, charge, molecular weight, and stability. We select appropriate lipids, excipients, and carrier structures, then optimize lipid ratios, particle size, and surface characteristics. This tailored approach ensures efficient drug encapsulation, controlled release, and reliable performance in the intended biological environment.

• What analytical and characterization capabilities do you offer?

  We provide comprehensive formulation characterization, including particle size and PDI analysis, zeta potential measurement, encapsulation efficiency, drug loading, release profiling, and stability testing. Advanced analytical techniques such as HPLC and LC-MS are used to ensure data accuracy. These evaluations allow us to optimize formulation quality, reproducibility, and performance at every development stage.

• Do you offer scalable and manufacturing-ready formulation processes?

  Absolutely. Scalability is a key consideration in our lipid formulation development strategy. We design processes that are compatible with industrial scale-up, using methods such as high-pressure homogenization and microemulsion techniques. Our team ensures batch-to-batch consistency, process robustness, and smooth technology transfer, supporting future clinical and commercial manufacturing requirements.
