(hpmc in tablet)
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.
Third-party laboratory tests demonstrate HPMC's exceptional functionality:
Parameter | HPMC | PVP | Starch |
---|---|---|---|
Binding Efficiency | 94% | 88% | 82% |
Disintegration Time (min) | 8-15 | 5-7 | 12-18 |
Moisture Resistance | Class IV | Class II | Class III |
HPMC tablets maintain ≥98% potency after 24-month accelerated stability testing, outperforming alternatives in humidity challenges.
A 2024 comparative study of leading suppliers revealed:
Vendor | Viscosity Range | Batch Consistency | Regulatory Filings |
---|---|---|---|
Supplier A | 5-200,000 cP | ±2.1% | DMF 34567 |
Supplier B | 50-100,000 cP | ±3.8% | EDMF-7890 |
Supplier C | 10-150,000 cP | ±1.7% | USP42/NF37 |

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.
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.
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.
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.
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.
