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:
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.
