AUROVISC EYE DROPS

Indications

• Dry eye conditions
• Tear deficiency
• Keratoconjunctivitis sicca

Dosage

Children: Apply as required, typically in the form of eye drops.

Adults: Apply as required, typically in the form of eye drops.

Mechanism of action

Hypromellose acts by forming a viscous gel upon contact with the ocular surface, which helps to retain moisture and protect against irritants. This gel-like property enhances the stability of the tear film and reduces evaporation, thereby alleviating symptoms associated with dry eye conditions.

Pharmacodynamics

The pharmacodynamic effects of hypromellose are primarily related to its ability to mimic natural tears, providing lubrication to the ocular surface. This lubrication reduces friction during blinking and maintains corneal hydration, which is critical for ocular comfort and health. Its high viscosity also contributes to prolonged retention time on the eye surface.

Pharmacokinetics

Hypromellose is administered topically as eye drops and is not significantly absorbed systemically. The retention time of hypromellose on the ocular surface is enhanced due to its viscosity, allowing for extended relief of dry eye symptoms. The elimination of hypromellose occurs primarily through drainage from the eye and dilution by the natural tear fluid.

Adverse effects

• Temporary visual disturbance
• Eye irritation

Precautions

• Should not be used during contact lens wear
• Use with caution in patients with known hypersensitivity to any component of the formulation

Pregnancy

Hypromellose is generally considered safe for use during pregnancy. However, it should be used only if clearly needed and after consulting a healthcare provider.

Breast-feeding

Hypromellose is unlikely to affect breastfed infants when used as directed, but consultation with a healthcare provider is advisable.

Storage

Store in a cool, dry place away from direct sunlight. Once opened, use within a specified period as indicated on the packaging.

Dosage

Children: Refer to specific drug monographs for dosage information as sterile itself is not a pharmacological agent.

Adults: Refer to specific drug monographs for dosage information as sterile itself is not a pharmacological agent.

Mechanism of action

Sterility itself does not have a mechanism of action as it is a state of cleanliness and does not interact with biological systems. However, the methods used to achieve sterility, such as heat or chemical agents, act by denaturing proteins, disrupting cellular structures, or damaging nucleic acids in microorganisms, leading to their inactivation or destruction.

Pharmacodynamics

The pharmacodynamics of sterile techniques primarily involves the prevention of microbial infection and contamination when administering medications. By ensuring that products are sterile, the risk of adverse effects related to infections is minimized. The effectiveness of sterilization methods can be influenced by factors such as temperature, duration of exposure, and the type of microorganisms present.

Pharmacokinetics

As sterility does not pertain to a specific drug, pharmacokinetics is not applicable. However, the pharmacokinetics of a drug will depend on its formulation, route of administration, and the presence of preservatives or stabilizers that may be used alongside sterile preparations.

Pregnancy

Sterile preparations are generally considered safe during pregnancy as they are used to provide hydration, nutrition, or medications in a controlled manner, but specific formulations should be assessed individually.

Breast-feeding

Sterile solutions used for hydration or nutritional support are typically safe during breastfeeding, but any specific additives or medications within the solutions should be evaluated for safety.

Storage

Sterile solutions should be stored in a cool, dry place, protected from light, and should be used before the expiration date. Once opened, they may have specific storage requirements based on the formulation.

• Sterile water for injection
