What are the key excipient components used in VIMPAT formulations?
VIMPAT (perampanel) is formulated as a film-coated tablet and oral suspension. Its excipient profile includes:
-
Film-Coated Tablet
- Lactose monohydrate: acts as a filler and binder.
- Microcrystalline cellulose: provides structural integrity.
- Croscarmellose sodium: disintegrant.
- Magnesium stearate: lubricant.
- Titanium dioxide: opacifier.
- Polyethylene glycol (PEG) 400: coating aid.
- Hypromellose: film former.
-
Oral Suspension
- Purified water.
- Sucrose: sweetener.
- Sodium benzoate: preservative.
- Sodium citrate: pH buffer.
- Flavors and coloring agents.
How does excipient selection influence VIMPAT’s commercial positioning?
Choice of excipients impacts manufacturing, stability, patient adherence, and regulatory compliance.
What are the opportunities for excipient innovation and commercialization?
Opportunities include:
-
Alternative Excipients for Sensitive Populations
- Replacing lactose with hypoallergenic fillers (e.g., cellulose derivatives) can expand patient base.
- Developing lactose-free formulations caters to lactose intolerance, broadening market reach.
-
Enhanced Delivery Formulations
- Creating once-daily extended-release versions using specific excipients.
- Developing orodispersible tablets with rapid disintegration, using superdisintegrants like crospovidone.
