Pharmacological action

Pharmacotherapy group: NSAIDs ATX code: M01AB15

Ketorolac has a pronounced analgesic effect, also has an anti-inflammatory and moderate antipyretic effect.

The mechanism of action is associated with non-selective inhibition of cyclooxygenase enzyme activity (COX-1 and COX-2), mainly in peripheral tissues, which results in inhibition of prostaglandin biosynthesis-modulators of pain sensitivity, thermoregulation, and inflammation. Ketorolac is a racemic mixture of [- ] S and [+]R-enantiomers, and the analgesic effect is due to the [-]S form.

Ketorolac does not affect opioid receptors, does not depress breathing, does not cause drug dependence, does not have a sedative and anxiolytic effect.

The strength of the analgesic effect is comparable to morphine, significantly superior to NSAIDs.

After oral use, the onset of analgesic action is noted, respectively, in 1 hour, the maximum effect is achieved in 1-2 hours.

Pharmacokinetics:

Suction

When taken orally, ketorolac is well absorbed from the gastrointestinal tract (GIT). Bioavailability – 80-100%. The maximum concentration (Cmax) in blood plasma (0.7-1.1 mcg / ml) is reached 40 minutes after taking ketorolac on an empty stomach at a dose of 10 mg. A fat-rich food reduces the Cmax of the drug in the blood plasma and delays its achievement by 1 hour.

Distribution

Binding to plasma proteins is 99%. With hypoalbuminemia, the amount of free ketorolac in the blood plasma increases.

The time to reach the equilibrium concentration (Css) when taken orally is 24 hours when used 4 times a day (above the subtherapeutic dose). The steady-state plasma concentration after oral use of 10 mg of ketorolac is 0.39-0.79 mcg / ml. The volume of distribution is 0.15-0.33 l / kg.

Metabolism

More than 50% of the administered dose is metabolized in the liver to form pharmacologically inactive metabolites. The main metabolites are glucuronides, which are excreted by the kidneys, and p-hydroxyketorolac.

Deduction

It is excreted by the kidneys by 91% (40% in the form of metabolites),6% – through the intestine.

After oral use of 10 mg of ketorolac, the half-life (T 1/2) in patients with normal renal function is on average 5.3 hours (2.4-9 hours). The total ground clearance is 0.025 l / kg / h. It is not excreted during hemodialysis.

Pharmacokinetics in special patient groups

Patients with impaired renal function

In patients with renal insufficiency, the volume of distribution of ketorolac can increase by 2 times, and the volume of distribution of its R-enantiomer-by 20%.

In renal insufficiency with a plasma creatinine concentration of 19-50 mg/l (168-442 mmol/L), T 1/2 is 10.3-10.8 hours, in more severe renal insufficiency – more than 13.6 hours.

Total clearance in renal insufficiency with a plasma creatinine concentration of 19-50 mg / ml when 10 mg of ketorolac is taken orally is 0.016 l/kg/h.

Patients with impaired liver

function Liver function does not affect T 1/2.

Elderly and young patients

T 1/2 lengthens in elderly patients and shortens in young patients.

Nursing mothers

Ketorolac penetrates into breast milk: after taking 10 mg of ketorolac by the mother, the Cmax in milk is reached in 2 hours and is 7.3 ng/ml, respectively,2 hours after taking the second dose of ketorolac (when using the drug 4 times a day) – 7.9 ng/ml.

Interaction

Concomitant use of ketorolac with acetylsalicylic acid or other NSAIDs, calcium supplements, glucocorticosteroids, ethanol, or corticotropin may significantly increase the risk of adverse reactions, including the formation of gastrointestinal ulcers and the development of gastrointestinal bleeding.

Concomitant use of ketorolac with anticoagulants (including warfarin, heparin), other NSAIDs, pentoxifylline and probenecid is contraindicated.

When ketorolac is co-administered with other NSAIDs (including cyclooxygenase-2 inhibitors), fluid retention, decompensation of cardiac activity, and increased blood pressure may occur.

Concomitant use of ketorolac with indirect anticoagulants, thrombolytics, antiplatelet agents, cefoperazone, cefotetan and pentoxifylline increases the risk of bleeding.

Probenecid reduces the plasma clearance and volume of distribution of ketorolac, increases its concentration in blood plasma and increases its half-life.

The combined use of ketorolac with sodium valproate causes a violation of platelet aggregation.

When using ketorolac with other nephrotoxic drugs (including gold preparations), the risk of developing nephrotoxicity increases. Combined use with paracetamol increases the nephrotoxicity of ketorolac. Drugs that block tubular secretion reduce the clearance of ketorolac and increase its concentration in blood plasma.

The combined use of ketorolac with methotrexate increases the hepatotoxicity and nephrotoxicity of methotrexate. The combined use of ketorolac and methotrexate is possible only when using low doses of the latter. Methotrexate clearance may decrease (it is necessary to monitor the concentration of methotrexate in blood plasma).

When ketorolac is used, it is possible to reduce the clearance of lithium, increase its concentration in blood plasma, and increase the toxic effect of lithium. Concomitant use with lithium salts is contraindicated.

Ketorolac reduces the effect of antihypertensive and diuretic drugs (reduces the synthesis of prostaglandins in the kidneys).

Ketorolac enhances the effect of narcotic analgesics. When combined with opioid analgesics, the doses of the latter can be significantly reduced.

Ketorolac enhances the hypoglycemic effect of insulin and oral hypoglycemic drugs, and therefore it is necessary to recalculate the dose of these drugs.

Ketorolac increases plasma concentrations of verapamil and nifedipine.

Concomitant use of NSAIDs and mifepristone may reduce the effectiveness of mifepristone. NSAIDs are not recommended for use within 8-12 days after the use of mifepristone.

Concomitant use of NSAIDs and cyclosporine increases the risk of nephrotoxicity.

Concomitant use of NSAIDs and quinolone antibiotics increases the risk of seizures.

Concomitant use of NSAIDs and tacrolimus increases the risk of nephrotoxicity.

Concomitant use of NSAIDs and zidovudine increases the risk of developing hematological toxicity.

When used concomitantly with digoxin, ketorolac does not interfere with the binding of digoxin to plasma proteins. Therapeutic concentrations of digoxin do not affect the binding of ketorolac to plasma proteins.

Antacids do not affect the absorption of ketorolac.

Myelotoxic drugs increase the manifestations of ketorolac hematotoxicity.

How to take, course of use and dosage

Inside, once or repeatedly, depending on the severity of the pain syndrome.

A single dose is 10 mg (1 tablet), with repeated use it is recommended to take 10 mg up to 4 times a day, depending on the severity of pain.

The maximum daily dose should not exceed 40 mg.

The duration of the course should not exceed 5 days.

To reduce the risk of adverse events, the minimum effective dose of ketorolac should be used in the shortest possible course.

Overdose

Symptoms: abdominal pain, nausea, vomiting, peptic ulcers of the stomach or erosive gastritis, impaired renal function, metabolic acidosis.

Treatment: gastric lavage, use of adsorbents (activated charcoal) and symptomatic therapy (maintenance of vital functions in the body). Ketorolac is not sufficiently eliminated by hemodialysis.

Special instructions

Before using the drug, it is necessary to find out about a previous allergy to the drug or other NSAIDs. Due to the risk of developing allergic reactions, the first dose is taken under the careful supervision of a doctor.

Ketorolac inhibits platelet aggregation and increases blood clotting time. The effect on platelet aggregation stops 24-48 hours after taking the drug.

Patients with blood clotting disorders are prescribed the drug only when the number of platelets is constantly monitored, which is especially important in the postoperative period, when careful monitoring of hemostasis is required.

Hypovolemia increases the risk of developing nephrotoxic adverse reactions.

If necessary, it can be used in combination with narcotic analgesics.

Do not use with paracetamol for more than 2 days.

The risk of adverse reactions increases with prolongation of the course of treatment and an increase in the oral dose of ketorolac more than 40 mg / day.

Concomitant use of ketorolac with probenecid, pentoxifylline, acetylsalicylic acid and other NSAIDs (including cyclooxygenase-2 inhibitors), lithium salts, anticoagulants (including warfarin and heparin) is contraindicated. It is contraindicated to use ketorolac for preventive pain relief before and during extensive surgical interventions due to the high risk of bleeding. Ketorolac is not recommended for use as a premedication agent and maintenance anesthesia.

Fluid retention, increased blood pressure, and edema have been reported with ketorolac.

Caution should be exercised when prescribing to patients with heart failure, arterial hypertension.

Concomitant use of ketorolac with other NSAIDs can lead to disorders such as decompensation of heart failure and increased blood pressure.

According to clinical studies, the use of certain NSAIDs in high doses may lead to an increased risk of arterial thrombotic complications (for example, myocardial infarction, stroke). Although no such complications have been reported with ketorolac, existing data are insufficient to rule out the risk of such complications.

To reduce the risk of developing NSAID-induced gastropathy, the use of antacids, misoprostol, as well as drugs that reduce gastric secretion (H2-receptor blockers of histamine, proton pump inhibitors) is recommended.

To reduce the risk of adverse events, the minimum effective dose of ketorolac should be used in the shortest possible course.

Influence on the ability to drive vehicles and mechanisms:

During treatment, side effects from the central nervous system (drowsiness, dizziness, headache) may develop, which reduces the speed of mental and motor reactions and therefore it is necessary to refrain from driving vehicles and engaging in other potentially dangerous activities that require increased concentration and speed of psychomotor reactions.
