  • Example: Croscarmellose sodium, Sodium starch glycolate.
• Lubricants: These prevent the powder blend from sticking to manufacturing equipment during compression or filling.
  • Example: Magnesium stearate.
• Capsule Shell Components: For capsule formulations.
  • Example: Gelatin, Hypromellose (HPMC) for vegetarian capsules.
• Solvents/Vehicles (for oral solutions):
  • Example: Ethanol, Propylene glycol, Glycerol.
• Preservatives (for oral solutions): To prevent microbial growth.
  • Example: Methylparaben, Propylparaben.
• Flavoring Agents and Sweeteners (for oral solutions): To improve palatability.
  • Example: Sucralose, Mint flavoring.

Who are the Key Excipient Suppliers?

The excipient market is broad, with many global suppliers. Pharmaceutical-grade excipients are produced by companies that adhere to strict quality standards and regulatory requirements. For Norvir, the specific excipients used in its proprietary formulation determine the exact suppliers. However, major global excipient manufacturers are likely sources.

Prominent global excipient suppliers include:

• BASF SE: A major producer of a wide range of pharmaceutical excipients, including polymers, surfactants, and solvents.
