CARBOXYMETHYL CELLULOSE + POLYVINYL ACETATE
Carboxymethyl Cellulose: Carboxymethyl Cellulose (CMC) is a medication in the form of a salt of carboxymethyl ether of cellulose. It is commonly used as a lubricating eye drop solution.
CMC acts as an artificial tear solution and is used to treat dry eyes by providing temporary relief from discomfort and irritation. It helps to moisturize the eyes and maintain proper lubrication.
The mechanism of action of CMC is to create a protective shield over the ocular surface, reducing evaporation and increasing eye lubrication. It forms a viscous film on the cornea and conjunctiva, promoting better retention of tears and preventing excessive water loss from the eyes.
The typical recommended dose of CMC eye drops is 1 to 2 drops in each affected eye, 3 to 4 times a day or as directed by a healthcare professional.
As with any medication, CMC can cause side effects in some individuals. Common side effects may include temporary eye burning or stinging upon application, temporary blurred vision, and increased sensitivity to light. These side effects are usually mild and transient.
It is important to note that CMC eye drops are for topical use only and should not be ingested. If any allergic reactions or severe side effects occur, it is recommended to seek medical attention promptly.
Polyvinyl Acetate: Polyvinyl Acetate is a type of adhesive commonly known as white glue or school glue. It is used for a variety of applications, including crafts, woodworking, and paper projects.
The mechanism of action of Polyvinyl Acetate involves the adhesion of molecules through intermolecular forces. When the glue is applied to a surface, the water in the glue partially evaporates, causing the polymer chains to bond together and create a strong adhesive bond.
The dose of Polyvinyl Acetate depends on the size of the project and the desired strength of the bond. It is typically applied directly to one or both surfaces that need to be bonded together. The adhesive usually takes a few minutes to dry and forms a strong bond within 24 hours.
As Polyvinyl Acetate is primarily used as an adhesive and not ingested orally or applied to the body, the chances of systemic side effects are minimal. However, some individuals may experience localized skin irritation or allergic reactions when in direct contact with the glue. It is important to avoid contact with eyes, mouth, or any open wounds.
In case of skin irritation or allergic reactions, it is recommended to wash the affected area with water and discontinue use. If symptoms persist or worsen, medical attention should be sought.
