Hypromellose Phthalate (HPMCP)丨CAS 9050-31-1

Hypromellose Phthalate (HPMCP) | CAS 9050-31-1 is a highly versatile cellulose derivative widely used in the pharmaceutical and nutraceutical industries. Known for its effectiveness as an enteric coating agent, it plays a crucial role in ensuring the controlled release and stability of oral dosage forms.

1.Pharmaceutical Industry:
- Enteric Coatings: HPMCP is primarily used to coat tablets, capsules, and granules, ensuring that the active ingredients are protected from the acidic environment of the stomach. This allows the medication to reach the intestines intact, where it can be released at the optimal absorption site.
- Controlled Release Formulations: By enabling the precise control of where and when the drug is released, Hypromellose Phthalate enhances the efficacy of medications, particularly for drugs sensitive to gastric acid or designed for targeted delivery.
- Sustained Release Applications: In some formulations, HPMCP contributes to sustained drug release, providing consistent therapeutic effects over extended periods.
2. Dietary Supplements:
- In nutraceutical applications, Hypromellose Phthalate ensures the stability and targeted release of supplements, such as probiotics or enzymes, that may be degraded by stomach acid.

1.Enhanced Stability:
- Acid Resistance: HPMCP provides robust protection for acid-sensitive active pharmaceutical ingredients (APIs), ensuring their stability until they reach the intended site of action in the intestines.
- Moisture Barrier: It acts as a moisture barrier, protecting the formulation from environmental humidity and extending shelf life.
2.Improved Bioavailability:
- By preventing premature disintegration in the stomach, Hypromellose Phthalate allows for precise delivery to the intestinal tract, enhancing the bioavailability and therapeutic efficacy of the active ingredients.
3.Patient-Centric Design:
- Reduced Side Effects: Enteric coatings made with HPMCP reduce gastric irritation, making it ideal for patients with sensitive stomachs or those taking medications prone to causing gastric discomfort.
- Enhanced Tolerance: For medications requiring delayed absorption, HPMCP ensures a gentler pharmacokinetic profile.
4.Formulation Flexibility:
- Wide pH Range: Hypromellose Phthalate dissolves in the mildly acidic to neutral pH of the intestines, making it suitable for a variety of controlled-release formulations.
- Versatile Applications: Compatible with multiple formulation techniques, including spray coating and fluid bed coating processes.

1.Storage Requirements:
- Hygroscopic Nature: HPMCP is hygroscopic and should be stored in a dry, controlled environment to prevent degradation or loss of effectiveness.
- Packaging: Use moisture-resistant packaging to preserve its integrity during storage and transport.
2.Compatibility Testing:
- API Interaction: While Hypromellose Phthalate is generally compatible with a wide range of APIs, formulation studies are necessary to assess potential interactions or stability issues with specific compounds.
3.Regulatory Standards:
- Compliance: As with all pharmaceutical excipients, HPMCP must meet stringent regulatory and quality standards to ensure product safety and efficacy.

Conclusion:
Hypromellose Phthalate (HPMCP) | CAS 9050-31-1 is a critical excipient in modern pharmaceutical and nutraceutical formulations. Its unique properties, such as acid resistance and controlled release capabilities, make it invaluable for enteric coating and targeted drug delivery. By enhancing stability, bioavailability, and patient compliance, HPMCP significantly contributes to the development of advanced oral dosage forms. Proper storage and compatibility assessments are essential to maximize its performance in diverse applications.
