Inactive Ingredients in Amoxicillin Preparations

Amoxicillin formulations contain more than just the active antibiotic. These inactive ingredients, also called excipients, play a critical role in the drug’s stability, effectiveness, and ease of administration. Their specific composition varies depending on the dosage form (e. g., capsules, tablets, suspensions).

Common inactive ingredients include:

Ingredient Category Examples Function
Fillers and Binders Cellulose, starch, lactose Provide bulk and cohesion to tablets and capsules.
Disintegrants Croscarmellose sodium, sodium starch glycolate Help the tablet or capsule break down in the stomach.
Lubricants Magnesium stearate, talc Improve the flow of powder during manufacturing and prevent sticking.
Glidants Colloidal silicon dioxide Improve the flow of powder during manufacturing.
Sweeteners Sucrose, aspartame Enhance the taste of liquid preparations, particularly for children.
Flavors Artificial fruit flavors Mask the unpleasant taste of amoxicillin.
Preservatives Methylparaben, propylparaben Prevent microbial growth in liquid formulations.
Suspending Agents Xanthan gum, acacia Keep the solid particles suspended in liquid formulations.

Always check the specific inactive ingredients listed on your amoxicillin product’s label. If you have allergies or sensitivities to any of these, consult your doctor or pharmacist before taking the medication. They can advise on alternative formulations or medications.
