What packaging formats do you recommend for ophthalmic products?

The choice of packaging format depends on the dosage and duration of treatment.
At Unither, clients can choose between:

• Sterile and preservative-free BFS single doses — often preferred for occasional or intermediate use (e.g. post-surgery)

• Multi-doses (with or without preservatives) — generally suitable for chronic-disease treatments such as glaucoma or dry eye

The decision is made as clinical development progresses, such as during a dose-ranging when the concentration, number of drops, and duration of treatment is defined.
