🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionSystemic absorption of ketorolac after topical ocular administration is minimal. However, some absorption can occur through the nasolacrimal duct and gastrointestinal tract if the solution drains into the nose and throat. The extent of systemic absorption is not well established from the available information.
DistributionAfter ocular administration, ketorolac distributes into ocular tissues, including the cornea, aqueous humor, and iris-ciliary body. Systemic distribution is limited due to low systemic absorption. Ketorolac is highly protein-bound in plasma. Not established from the available information for ocular route.
Protein BindingKetorolac is approximately 99% bound to plasma proteins, primarily albumin. This high protein binding is relevant if systemic absorption occurs.
MetabolismKetorolac is metabolized in the liver primarily via glucuronic acid conjugation to form ketorolac glucuronide. Other metabolites include p-hydroxyketorolac. The metabolism of ketorolac is not significantly affected by ocular administration due to minimal systemic absorption.
Half-LifeThe elimination half-life of ketorolac after systemic administration is approximately 5 to 6 hours. After ocular administration, the half-life in ocular tissues may differ, but it is not well established from the available information.
ExcretionKetorolac and its metabolites are excreted primarily in the urine (approximately 91%) and to a lesser extent in feces (approximately 6%). After ocular administration, systemic excretion is minimal.
BioavailabilityThe systemic bioavailability of ketorolac after ocular administration is not well established from the available information. It is expected to be low compared to oral or intramuscular administration.
Onset of ActionThe onset of action for ocular ketorolac is typically within 30 minutes to 1 hour after instillation, with peak effects occurring within 1 to 2 hours. However, individual responses may vary.
Peak Plasma TimePeak plasma concentrations after ocular administration are not well established from the available information. Systemic absorption is minimal.
Duration of ActionThe duration of action of this medicine is typically 4 to 6 hours, but it may vary depending on the individual and the condition being treated. Frequent dosing is usually required to maintain therapeutic effect.

How It Works

This medicine works by reversibly inhibiting the cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. These enzymes catalyze the conversion of arachidonic acid into prostaglandin H2, which is a precursor for various prostaglandins and thromboxanes. By blocking this pathway, ketorolac reduces the synthesis of prostaglandins, which are key mediators of inflammation, pain, and fever. In the eye, prostaglandins contribute to vasodilation, increased vascular permeability, and leukocyte migration, all of which lead to the signs and symptoms of ocular inflammation. Inhibition of prostaglandin synthesis thus reduces redness, swelling, and pain. Ketorolac does not have significant effects on lipoxygenase pathways and does not bind to opioid receptors.

Mechanism Steps

1
Penetration into ocular tissues: After instillation, ketorolac penetrates the cornea and reaches the aqueous humor and other ocular tissues.
2
Inhibition of cyclooxygenase enzymes: Ketorolac reversibly binds to and inhibits COX-1 and COX-2 enzymes, blocking the conversion of arachidonic acid to prostaglandin H2.
3
Reduced prostaglandin synthesis: The inhibition of COX enzymes leads to decreased production of prostaglandins, which are mediators of inflammation and pain.
4
Decreased inflammatory response: With lower prostaglandin levels, there is less vasodilation, vascular permeability, and leukocyte infiltration, resulting in reduced ocular inflammation and pain.
