Classification of Pharmaceutical Excipients

Pharmaceutical excipients play a vital rule in new drug development. The choice of excipients is a critical step for a formulation development scientistto select the right grade and quantity of the material. So for choosing a right excipients you should know the excipients nature, origin and compatibility with API. From this aspect here we try to classify the pharmaceutical excipients in different ways, which will help your development works.

Types of Excipients

Based on Route of Administration

Based on Origin

  • Marine Source: Agar, Alginate, Chitosan etc.
  • Animal Source:lactose, gelatin, bees wax etc.
  • Inorganic Source: Calcium Carbonate, Calcium Phosphate etc.
  • Organic Source: Sugars, Starch, Cellulose etc.
  • Synthetic Source: Povidone, Polysorbate etc.
  • Semi-synthetic source: HPC, HPMC etc.

Based on Function

Novel Excipients

  • Captisol (Cydex)
  • Soluplus (BASF)
  • Kollicoat (BASF)

Co-processed Excipients

  • Ludipress (BASF)
  • Ludiflash (BASF)
  • Pharmaburst (SPI)
  • Starcap 1500 (Colorcon)
  • Aquarius (Ashland)

Multifunctional Excipients
