Frequently Asked Questions (FAQ)

1. How do I choose the right excipient for my drug?

The selection of the right excipient depends on the dosage form, therapeutic effect and absorption requirements of the drug. For example, for oral tablets, it is crucial to choose the right disintegrant and binder; for injections, the choice of solvent and buffer affects the stability and absorption rate of the drug. We recommend working with TJCY's technical team to ensure that the best excipient is selected for your drug.

2. How do the excipients provided by TJCY ensure the stability of the drug?

The excipients provided by TJCY are rigorously tested for stability. Excipients such as thickeners, emulsifiers, and antimicrobial preservatives can help ensure that the drug is not affected by environmental changes throughout the shelf life, avoiding drug degradation or microbial contamination. Our excipient products meet the standards of major global pharmacopoeias (such as USP, EP), ensuring the safety of drugs during long-term storage or transportation.

3. What are the key factors in the selection of excipients in oral tablets?

In oral tablets, excipients such as disintegrants, binders, and lubricants are crucial. Disintegrants help drugs disintegrate and be absorbed quickly in the gastrointestinal tract, binders ensure the structural integrity of tablets, and lubricants prevent mold jams and increase fluidity during the production process. Depending on the solubility, absorbability and other characteristics of the drug, the selection and proportion of excipients will vary.

4. How to ensure the safety of excipients for patients?

All excipients provided by TJCY are strictly quality controlled and meet international GMP standards. Our excipient products do not contain harmful substances and have undergone various toxicology and biocompatibility tests to ensure that there will be no side effects on patients during drug preparation and application.

5. Do excipients affect the bioavailability of drugs?

Yes, the choice of excipients directly affects the bioavailability of drugs. For example, solvents and emulsifiers help drugs dissolve better and increase absorption rate; while sustained-release agents can prolong the release time of drugs and improve therapeutic effects. TJCY's excipients provide a variety of types to help optimize the bioavailability of drugs and ensure maximum efficacy.
