์์ฉ ๊ธฐ์ : **Glycerin** exerts its effects purely through physical osmotic forces rather than specific receptor interactions. * **Osmotic Gradient**: When administered orally, it rapidly increases the osmolality of the blood plasma. * **Fluid Shift**: This hyperosmolar state draws water from extravascular spaces (including the aqueous and vitreous humor of the eye, and cerebrospinal fluid) into the intravascular space โ **Decreased IOP** and **Decreased CSF pressure**. * **Metabolism**: Once in the liver, glycerin is metabolized via the enzyme **glycerol kinase** โ glycerol-3-phosphate โ enters glycolysis and gluconeogenesis pathways.

Specific veterinary overdose information is limited. However, **cardiac arrhythmias**, **non-ketotic hyperosmolar coma**, and **severe dehydration** have been reported with the drug. Treatment should be supportive and symptomatic, focusing on restoring fluid and electrolyte balance.
