Sixty-one separate self-injections of ketorolac tromethamine (Toradol) by 16 patients diagnosed with episodic migraine with or without aura were evaluated over a 90-day period for safety, efficacy of pain reduction, and the ability of this therapy program to prevent the necessitation of emergency room acute care. Prior to initiation of treatment, patients were formally instructed on intramuscular injection techniques by a member of our nursing staff. Patients were instructed to call upon the onset of a severe headache interfering with daily functioning and, then, were permitted to proceed with the injection. Headache intensity ratings were collected prior to injection and intermittently for the following twenty-four hours. The results demonstrate safety and efficacy of this form of therapy. A significant percent of ketorolac usages (64%) resulted in a good response and significant reduction in head pain. Twenty-three percent of ketorolac usages resulted in a mild response and only 13% of usages provided no relief. Furthermore, 13% of all usages failed to prevent the necessitation for emergency room treatment. The results are discussed in terms of the impact of self-injection on pain relief and substantial cost-reduction by decreasing emergency room utilization.

Ketorolac tromethamine is a new injectable/oral nonsteroidal anti-inflammatory analgesic with no apparent opiate receptor activity that has been administered alone and in combination with other opiate analgesics for the treatment of postoperative pain. The drug has shown promise in analgesic comparisons with morphine sulfate; it lacks the effects of respiratory depression and nausea and vomiting usually associated with narcotic agents. Intramuscular ketorolac may be particularly useful with those patients who have respiratory disease and patients being dismissed following short ambulatory or private-office anesthetic procedures.

Providing adequate pain control with minimal side effects in inpatient and ambulatory settings is a continuous challenge to the PACU nurse. Ketorolac tromethamine (Toradol, Syntex, Palo Alto, CA) is a new parenteral nonsteroidal anti-inflammatory drug (NSAID) approved for use in the United States. Ketorolac is useful in the management of short term, moderate to severe postoperative pain. It is used by itself or as an adjunct to traditional opioid analgesics. Ketorolac, like other NSAIDs, has analgesic, anti-inflammatory, and antipyretic properties. Unlike morphine or meperidine, ketorolac does not bind to opioid receptors and is not a centrally acting agent. Administered intramuscularly, peak plasma levels are reached in 45 to 50 minutes. It is administered as a 30- or 60-mg intramuscular (IM) loading dose followed by 15- or 30-mg doses IM every 6 hours, with a maximum first-day dose of 150 mg and 120 mg on subsequent days up to a recommended maximum of 5 days. The lower dose range is recommended for elderly patients, patients weighing less than 50 kg, and patients with impaired kidney function. Initial studies show that use of ketorolac decreases the overall amount of opioid analgesia needed for postoperative pain control. To date, reported occurrence of side effects is low. A case study presents a healthy ambulatory surgical patient admitted for inguinal hernia repair using epidural anesthesia. Use of ketorolac has shown initial favorable results. More research is needed to further define its role and side effects in postoperative pain management.

Twelve patients presenting to an emergency department in headache crisis were treated with Ketorolac tromethamine 60 mg. intramuscularly. All improved sufficiently to require no further emergent treatment. There was statistically significant improvement on all segments of the short form McGill Pain Questionnaire. This open label trial suggests that Ketorolac Tromethamine may be a useful agent in the treatment of headache crisis, and a controlled study to examine this is warranted.

Ketorolac tromethamine is the first injectable nonsteroidal anti-inflammatory drug approved for the management of acute pain. In analgesic potency and ability to relieve postoperative pain, it is comparable to morphine. The advantages of ketorolac over opiates are the absence of respiratory depression and lack of drug abuse potential. Ketorolac has a longer duration of action than morphine, but it has less effect on the central nervous system. Ketorolac should not be used for obstetric analgesia.

Ketorolac tromethamine is a highly potent member of a class of compounds having both analgesic and antiinflammatory activity. In animal pain models using underlying inflammation, ketorolac markedly inhibited the pain response and increased the pain threshold; it did not exhibit any narcotic or central nervous system depressant effects. It was also active in rat models of acute and chronic inflammation and pyresis. These activities are mediated primarily by potent prostaglandin cyclooxygenase inhibitory activity. Mild central nervous system and cardiovascular effects occurred only at doses far greater than those required for analgesic and antiinflammatory activity. Solutions of ketorolac tromethamine are not irritating. When given intramuscularly to rabbits (0.31-5% solutions), no drug-related irritation or changes in serum creatine phosphokinase were seen. The agent was not irritating when applied to the skin or eyes (less than or equal to 0.5% solutions) of animals.

Ketorolac tromethamine, a potent nonnarcotic prostaglandin synthetase-inhibiting analgesic, was compared with meperidine for relief of moderate to severe postoperative pain. In a double-blind, randomized study, 125 patients received single intramuscular doses of ketorolac 30 or 90 mg or meperidine 50 or 100 mg. The degree of pain and pain relief were quantified verbally and with visual analog scales at baseline and 30 minutes, then hourly for 6 hours. Ketorolac 30 and 90 mg were significantly superior to meperidine 50 mg in six of nine efficacy measures. The onset of and peak analgesic effect of both doses of ketorolac and of meperidine were equivalent. Compared with both doses of meperidine, the two doses of ketorolac exhibited significantly longer duration of analgesic effect, as measured by the percentage of patients who terminated the study because of inadequate pain relief. The frequency of side effects was not significantly different between the drugs. The prolonged efficacy of intramuscular ketorolac combined with the reduced risk of respiratory depression suggest an important use of this drug for the relief of postoperative pain.

Ketorolac tromethamine is a potent prostaglandin synthetase inhibitor useful in the treatment of postoperative pain. Since it is also known to have antiplatelet properties, we determined the effect of ketorolac, alone and in combination with low-dose heparin, on hemostasis. Each of 12 healthy male volunteers received the following drug combinations on a double-blind, crossover basis: ketorolac dummy/heparin dummy, ketorolac active/heparin dummy, ketorolac active/heparin active, and ketorolac dummy/heparin active. Ketorolac significantly prolonged bleeding time, and inhibited platelet aggregation and platelet thromboxane production. Heparin had no effect on bleeding time or platelet function, but significantly prolonged the kaolin-cephalin clotting time and increased anti-Xa levels. Ketorolac had no effect on the kaolin-cephalin clotting time or anti-Xa levels, and no interaction was found between ketorolac and heparin. The modest prolongation of bleeding time with ketorolac is unlikely to be of any major clinical significance, as the value remained within the normal range in almost all subjects. However, because of its antiplatelet properties, the drug should be used with caution in persons with hemostatic disorders.

Ketorolac tromethamine is a pyrrolo-pyrrole nonsteroidal antiinflammatory drug (NSAID) with potent analgesic effects when administered intramuscularly for the treatment of acute pain. Ketorolac is well absorbed and has a rapid onset of action. Maximum plasma concentrations are achieved in 45-50 minutes and peak analgesic effects in about one to two hours following intramuscular injection. Ketorolac is more than 99 percent bound to plasma proteins and has a mean apparent volume of distribution of 0.11-0.25 L/kg. About 91 percent of a dose is excreted in urine, mostly as inactive metabolites, and approximately 6 percent is eliminated in feces. The elimination half-life, approximately four to six hours, increases in elderly patients and those with renal impairment. Its analgesic effectiveness was similar or superior to that of morphine, meperidine, or pentazocine in single-dose studies of patients with postoperative pain or renal colic and greater than that of placebo in patients with chronic cancer pain. The adverse effects are generally mild to moderate, self-limiting, and similar to those seen with other prostaglandin inhibitors. Ketorolac has a reversible inhibitory effect on platelet aggregation. It can cause dose-related gastric ulcerations, even when administered parenterally. Ketorolac is a promising parenteral alternative to oral NSAIDs and a nonnarcotic alternative to opioid analgesics. Additional multiple-dose studies are needed to more clearly define its place in therapy.

Clinical studies of the injectable nonsteroidal anti-inflammatory agent (NSAIA) ketorolac tromethamine are reviewed, and the chemistry, pharmacology, pharmacokinetics, drug interactions, and adverse effects of ketorolac are described. Ketorolac exhibits anti-inflammatory, analgesic, and antipyretic activity. Although the exact mechanisms of action have not been determined, its effects appear to be associated principally with the inhibition of prostaglandin synthesis. After oral, i.m., or i.v. administration, ketorolac and its metabolites are excreted mainly in urine. Ketorolac tromethamine has been used for the symptomatic relief of moderate to severe postoperative pain, including that associated with abdominal, gynecologic, oral, orthopedic, or urologic surgery. Ketorolac has also been used for the relief of acute renal colic, pain associated with trauma, and visceral pain associated with cancer. When administered i.m., ketorolac produced analgesia comparable to that of i.m. doses of meperidine, pentazocine, or morphine. The most common adverse effects associated with short-term administration are nervous system and gastrointestinal effects; these are usually mild and occur in about 39% of patients. Unlike opiate analgesics, ketorolac does not appear to cause tolerance or physical dependence in patients receiving long-term therapy. Ketorolac tromethamine has been administered concomitantly with morphine or meperidine without apparent adverse interaction. For short-term pain management, an initial i.m. ketorolac tromethamine loading dose of 30 or 60 mg is recommended. Ketorolac tromethamine appears to be as effective as morphine or meperidine for short-term management of moderate to severe postoperative pain. It lacks the respiratory depressant effects of opiate analgesics but shares the toxic potentials of other NSAIAs.
