Abstract:
The present invention relates to a preservative-free, aqueous solution in the form of eye drops packed in a container that ensures stability of the product, ideal eye drop volume and reduced drop volume variability and provides efficient dispensing.

Claim (Index 6):
A multi-use ophthalmic kit comprising:\n a container comprising an integral bacterial protection system and a dispensing tip; an ophthalmic composition contained within the container and configured to be dispensed as drops from an orifice of the dispensing tip into an eye of a patient; wherein the dispensing tip orifice geometry comprises a ratio of an inner diameter to an outer diameter of the dispensing tip orifice from 1:1 to 1:6, wherein the inner diameter of the dispensing tip orifice is more than 0.3 mm and less than 2 mm and the outer diameter of the dispensing tip orifice is more than 1 mm and less than 4 mm, wherein the outer diameter is the diameter of the dispensing tip at a point a drop exits the dispensing tip and the inner diameter is the diameter of the dispensing tip at the point the drop exits the dispensing tip and to which internally the ophthalmic composition moves from the container to the tip; wherein the ophthalmic composition comprises a preservative-free aqueous solution of timolol as an active ingredient and pharmaceutically acceptable excipients selected so as to provide the following physical properties to the solution: a) viscosity of less than 200 cP at 25\u00b0 C. as measured by European pharmacopoeia requirements b) surface tension of less than 22 mN/m and more than 10 mN/m at 25\u00b0 C. c) osmolality value of 250 to 300 mOsm/Kg; wherein the ophthalmic composition is free of viscosity increasing agents; wherein the integral bacterial protection system uses a mechanical tip-seal technology to prevent bacterial contamination and the mechanical tip-seal technology comprises a spring-loaded valve located directly below the dispensing tip orifice; and wherein the container is configured to dispense drops of the ophthalmic composition having a volume of between 22 \u03bcl and 31 \u03bcl when the dispensing tip is oriented at an angle of 45\u00b0 relative to a horizontal axis and wherein variability between each drop dispensed is +7 \u03bcl.
