Ophthalmics Process by Merck - Keep a close eye on quality and safety

Reduce risk and overcome challenges

Ophthalmic drugs pose special formulation challenges to manufacturers. In general, choosing the right processes and materials is important to ensure the required quality, drug tolerability and patient adherence. Formulators must pay attention to tonicity, pH, stability and viscosity, as well as sterility and microbiological purity, which has to be assured throughout the time of use. The final ophthalmic formulation must remain sterile, microbially pure, and stable throughout shelf life. Finding the right excipient that supports these needs is key.

Merck´s large product portfolio covers all excipient groups required for ophthalmic formulation, such as viscosity enhancers, surfactants, buffers and pH regulation agents, isotonicity adjusting agents as well as antioxidants and preservatives – all in the right quality.

Mitigate risk during formulation development.

For an ophthalmic formulation to succeed, making sure all of its properties are in line with regulatory guidelines right from the start is essential.

We are aware that developing formulations to treat ocular diseases is challenging and that requirements for the final product are high. To support full supply chain transparency and risk mitigation, we not only provide excipients in the highest quality but also in-depth, consistent documentation in a centralized location, so you can access the information you need when you need it. And when it comes to regulatory expertise, our experts
are always here to support you.

Emprove® Program and documentation

Make the most of our preservatives.

Preservatives are used in liquid and semi-solid formulations to prevent microbial growth in pharmaceutical products and to increase the products’ shelf life. The solubility and chemical properties of preservatives mean they can be used in different types of formulations.

We offer a broad portfolio of preservatives suitable for multiple administration routes and dosage forms. And to help you navigate regulatory challenges, manage risks, and improve your manufacturing processes, we offer comprehensive documentation as part of our Emprove® Program.
