Why the "Container" is a Critical Component
The eye is exceptionally sensitive. The plastic bottle housing your solution must be:
Inert: It cannot interact with or absorb the active pharmaceutical ingredients (APIs).
Sterilizable: It must withstand sterilization processes like gamma irradiation or ETO without degrading.
Durable: It must protect the solution from external contaminants and environmental factors.
Squeezable: It must allow for easy, controlled dosing by the patient.
The material you select directly impacts all these factors. Let's compare the two most common contenders.
