purified water, ophthalmic

Action and Spectrum

Actions and Spectrum: 

Action:  

purified water, ophthalmic, is a specially formulated type of water used in the field of ophthalmology and eye care. Its primary action is to provide a clean, sterile, and non-irritating medium for various ophthalmic procedures and treatments. 

Spectrum: 

Purity: purified water, ophthalmic, undergoes rigorous purification processes to remove impurities, contaminants, and microorganisms. It typically meets stringent purity standards to ensure its suitability for use in the delicate eye area. 

Sterility: The water is subjected to sterilization methods, such as filtration and/or heat treatment, to eliminate any viable microorganisms that may cause infections or other complications when in contact with the eyes.

Contraindication / Caution

Contraindication/Caution:  

Known Allergies: Individuals with known hypersensitivity or allergic reactions to any component of the purified water solution should avoid using it. This includes allergies to certain preservatives or other additives that might be present in the formulation. 

Eye Infections or Ocular Conditions: The drug is not intended for treating or managing eye infections or any other specific ocular conditions. If you have an existing eye infection or any other ocular condition, it is important to consult with an eye care professional for appropriate diagnosis and treatment. 

Severe Eye Injuries: In case of severe eye injuries, it is important to seek immediate medical attention rather than relying solely on purified water. Severe eye injuries may require specialized medical treatment, and purified water may be insufficient or appropriate. 

Contact Lens Use: purified water, ophthalmic, is generally not recommended for use as a contact lens solution. If you wear contact lenses, it is important to use the appropriate contact lens solution as directed by your eye care professional. 

Pregnancy / Lactation

Pregnancy warnings:     

Pregnancy category: N/A 

Lactation: Excreted into human milk is unknown 

Pregnancy Categories:         

Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus in either the first or second trimester. 

Category B: There were a lack of studies on pregnant women and no evidence of risk to the fetus in animal experiments.   

Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.    

Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.   

Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.    

Category N: There is no data available for the drug under this category

Pharmacology

Pharmacology:  

purified water, ophthalmic, also known as sterile water for ophthalmic use, is a specific formulation of purified water intended for use in ophthalmic (eye-related) applications. 

Pharmacodynamics:  

Moistening and Lubrication: Drug acts as a hydrating agent, helping to alleviate dryness and discomfort in the eyes. It provides lubrication to the ocular surface, reducing friction and improving the smooth movement of the eyelids. 

Cleansing and Rinsing: The sterile nature of purified water makes it suitable for cleansing and rinsing the eyes. It can be used to remove debris, foreign particles, or contaminants from the ocular surface, providing a clean and clear environment for the eyes.  

Pharmacokinetics: 

Absorption 

When used in ophthalmic procedures or as an eye wash, purified water is applied topically to the ocular surface. It can be absorbed by the cornea and conjunctiva, providing hydration and moisture to the eye. 

Distribution 

Once applied, purified water distributes evenly over the ocular surface due to the lubricating and wetting properties of the liquid. It helps to flush out debris and contaminants from the eye. 

Metabolism 

purified water does not undergo any significant metabolic processes within the eye or the body. It is considered inert and does not undergo chemical changes. 

Excretion and Elimination 

 After application, any excess purified water is typically drained away through the nasolacrimal ducts, which connect the eye to the nasal cavity. It is eventually eliminated from the body through natural processes like urination. 

Adminstartion

Administration:  

The administration of purified water, ophthalmic refers to the use of sterile purified water specifically formulated for ophthalmic (eye-related) purposes. It is used to clean and rinse the eyes, particularly in situations where there is a need for gentle irrigation or removal of foreign substances from the eye.

Generic Name: purified water, ophthalmic 

Why do we use purified water, ophthalmic?  

Eye Irrigation: purified water is used for eye irrigation during ophthalmic procedures or to flush foreign objects or irritants from the eye. It helps to cleanse the eye and maintain its moisture. 

Eye Drops and Solutions: purified water serves as a base for ophthalmic medications, eye drops, and solutions. It is used as a carrier for active ingredients, ensuring the safety and efficacy of the medication when applied to the eye. 

Contact Lens Cleaning and Disinfection: purified water is used in contact lens solutions for cleaning and disinfecting contact lenses. It helps to remove debris and microorganisms from the lenses, reducing the risk of eye infections. 

Eye Wash Stations: In workplaces, laboratories, and healthcare facilities, eye wash stations are equipped with purified water. They provide immediate flushing of the eyes in case of chemical exposure or accidental eye contamination.
