Why HPMC in Tablet Manufacturing is a Game-Changer

Hydroxypropyl methylcellulose (HPMC) has become the polymer of choice for 68% of sustained-release tablet formulations globally (PharmaTech Journal, 2023). Its unique water solubility and pH-independent swelling properties enable precise control over drug release profiles. The global HPMC for pharmaceutical applications market is projected to reach $1.2 billion by 2028, growing at 6.7% CAGR, driven by increasing demand for complex generics and OTC medications.

Technical Superiority in Binder Performance

Third-party laboratory tests demonstrate HPMC's exceptional functionality:

HPMC tablets maintain ≥98% potency after 24-month accelerated stability testing, outperforming alternatives in humidity challenges.

FAQS on hpmc in tablet

Q: What is the role of HPMC in tablet formulations?

A: HPMC (Hypromellose) acts as a binder, disintegrant, and controlled-release agent in tablets. It improves tablet integrity and regulates drug dissolution. Its viscosity grade determines its functionality in the formulation.

Q: Why is HPMC preferred for tablet coatings?

A: HPMC forms a smooth, durable film coating that protects tablets from moisture and oxidation. It is biocompatible, odorless, and supports sustained-release profiles. It also enhances tablet appearance and swallowability.

Q: How does HPMC tablet coating improve drug delivery?

A: HPMC coatings control drug release by forming a hydrophilic gel barrier. This enables timed or site-specific delivery in the gastrointestinal tract. It also minimizes gastric irritation for sensitive APIs.

Q: What factors influence HPMC performance in tablet formulations?

A: Key factors include HPMC viscosity grade, particle size, and concentration. Processing conditions like hydration time and mixing speed also affect its binding, coating, or release-modifying properties.

Q: Can HPMC replace other excipients in tablet manufacturing?

A: HPMC often replaces gelatin or synthetic polymers due to its non-ionic, pH-independent solubility. It offers superior stability and compatibility with APIs compared to some traditional binders or coatings.
