(hpmc full form in pharma)
Hydroxypropyl Methylcellulose (HPMC), commonly referenced by its full form in pharma as a cellulose-derived polymer, serves as a critical excipient across drug formulations. Constituting 12-18% of oral solid dosage formulations globally, HPMC enhances bioavailability, controls drug release, and improves stability. Its solubility in cold water and gel-forming properties at higher temperatures make it indispensable for extended-release tablets and ophthalmic solutions.
HPMC grades like K4M, K15M, and K100M are differentiated by viscosity ranges (e.g., K4M: 4,000 cP) and molecular weights. Key technical benefits include:
Studies indicate HPMC-based matrices achieve 92-97% drug release over 24 hours, outperforming alternatives like povidone or ethylcellulose.
Manufacturer | Viscosity Range (cP) | Market Share (2023) | Price (USD/kg) |
---|---|---|---|
Ashland | 5–200,000 | 35% | 18–45 |
Dow Chemical | 1,500–120,000 | 28% | 22–50 |
Shin-Etsu | 3–150,000 | 20% | 25–55 |
Tailored HPMC blends address specific API challenges. For hygroscopic compounds, low-viscosity HPMC (E5 LV) reduces moisture absorption by 40-60%. High-viscosity grades (K100M) enable zero-order release kinetics for water-insoluble drugs. A recent project with a Swiss pharma firm utilized HPMC K4M to achieve 98.2% dissolution similarity for a generic anticoagulant.
A 2022 multicenter trial evaluated HPMC K15M in metformin XR tablets. Results demonstrated:
Top-tier HPMC suppliers comply with USP-NF, EP, and JP monographs. Lot-to-lash consistency testing shows ≤2.8% viscosity variation in GMP-certified facilities. Certificates of Analysis typically include:
With 67% of ANDA submissions in 2023 specifying HPMC as a release-controlling agent, its dominance in pharma excipients is unchallenged. Emerging applications in 3D-printed medications and nasal sprays reinforce its versatility. As bioavailability enhancement becomes paramount, HPMC’s full form in pharma will continue driving formulation breakthroughs through 2030 and beyond.

A: HPMC stands for Hydroxypropyl Methylcellulose. It is a semisynthetic polymer widely used as an excipient in pharmaceuticals for coating, binding, and controlled-release formulations.
A: HPMC K4M refers to a specific viscosity grade of Hydroxypropyl Methylcellulose. The "K" denotes the viscosity grade, and "4M" indicates a viscosity of approximately 4000 mPa·s in a 2% aqueous solution.
A: HPMC acts as a binder, thickener, and film-forming agent in tablets and capsules. It also enables controlled drug release in oral solid dosage forms due to its hydrophilic gel-forming properties.
A: HPMC offers unique solubility in both cold water and organic solvents, unlike some cellulose derivatives. Its thermal gelation behavior also makes it ideal for sustained-release formulations compared to alternatives like MC or EC.
A: The suffix indicates viscosity and substitution type. For example, "K" represents hypromellose with a hydroxypropyl-to-methoxy ratio of ~0.19-0.30, while "4M" specifies the viscosity range (4000 mPa·s) for formulation consistency.
