METOLOSE

Shin-Etsu Pharma, Nutra and Food Brand

Shin-Etsu Chemical Co., Ltd. began to produce water soluble cellulose ethers in 1962, with the trade name METOLOSE®. METOLOSE® consists of Methylcellulose (methylcellulose USP) and three substitution types of Hydroxypropylmethylcellulose (Hypromellose USP) each available in several grades differing in viscosity. METOLOSE® can be used as a binder for solid dosage forms such as tablets and granules. It also provides a variety of functions such as water retention, thickening, protective colloid, surface activity, etc. It also can be used as a hydrophilic matrix agent. The hydrophilic matrix system is the simplest sustained release technology for oral dosage forms, consisting essentially of a drug and a water soluble highly viscous polymer. Recent advances in this hydrophilic matrix system have allowed more controllable and reproducible drug release by controlling the chemical and physical properties of the polymer. METOLOSE® SR is especially suitable for this application, and provides a genuine consistency in the final products.

Brand Highlights
  • Metolose®
  1. Non ionic and water soluble polymer with various viscosity.
  2. Applicable as film strips and dispersant of liquid formulation
  3. SM-4 is recommendable for pellet coating as it is less sticky. The thermal gelling helps to  prevent  agglomerations  during  the  coating process  even  at  the  higher spray speed.
  • Metolose® SR
  1. For  Hydrophilic  matrix  formulation  of  API  and  METOLOSE®    SR  to extend  the dissolution.  The  dosage  forms  can  be obtained by direct compression or granulation process.
  2. METOLOSE®  SR has specifications of particle size which can be suitable for sustained release application.
  3. Dissolution profile can be easily adjusted by selecting appropriate grade.
  4. Recommendable amount of METOLOSE®  SR is more than 20% in the formulation in order to form the stable gel layer.
