Pharma-Grade Excipients From GMP Manufacturers In China

#1. Definition:

All materials in your medicine except the active pharmaceutical ingredients are excipients.

We use excipients to give our medicines a form.

Excipients also make sure our medicine is effective, stable, and safe to use.

We will select excipients based on the API characteristics and the dosage forms.

You see all the contents of your pills on the leaflet, right?

You exclude its active ingredients, all others are excipients.

Excipients are the basic materials and important components of pharmaceutical preparations.

These excipients are the basis where we make medicine production and development possible.

You can say that they play a key role in the formulation and production of pharmaceutical preparations.

As the excipient gives our drug a dosage form with improved efficacy and reduced adverse reactions.

Plus, medicine manufacturers rely on excipients’ quality and diversity to make more new dosage forms.

Many types of excipients can be used as API carriers, to improve drug stability and solubilization.

We will also need certain excipients for dosages of sustained and controlled release.

These excipients are so important that they will greatly affect the drug quality and safety
