What is Algikey?

Algikey is a nonsteroidal anti-inflammatory drug (NSAID). Algikey works by reducing hormones that cause inflammation and pain in the body.

Algikey is used short-term (5 days or less) to treat moderate to severe pain.

Algikey may also be used for purposes not listed in this medication guide.

Algikey indications

Carefully consider the potential benefits and risks of Algikey Tromethamine and other treatment options before deciding to use Algikey. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

Acute Pain in Adult Patients

Algikey Tromethamine is indicated for the short-term (≤5 days) management of moderately severe acute pain that requires analgesia at the opioid level, usually in a postoperative setting. Therapy should always be initiated with IV or IM dosing of Algikey Tromethamine, and oral Algikey Tromethamine is to be used only as continuation treatment, if necessary.

The total combined duration of use of Algikey Tromethamine injection and oral Algikey Tromethamine is not to exceed 5 days of use because of the potential of increasing the frequency and severity of adverse reactions associated with the recommended doses. Patients should be switched to alternative analgesics as soon as possible, but Algikey Tromethamine therapy is not to exceed 5 days.

Algikey Tromethamine injection has been used concomitantly with morphine and meperidine and has shown an opioid-sparing effect. For breakthrough pain, it is recommended to supplement the lower end of the Algikey Tromethamine injection dosage range with low doses of narcotics prn, unless otherwise contraindicated. Algikey Tromethamine injection and narcotics should not be administered in the same syringe.

How should I use Algikey?

Use Algikey spray as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Algikey spray comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Algikey spray refilled.
• Do not take Algikey spray by mouth. Use in your nose only.
• Before you use each bottle for the first time, you must prime it. Remove the clear plastic cover and the blue plastic safety clip. Hold the bottle at arm's length away from you. Using your index and middle fingers on the top of the bottle and your thumb on the bottom of the bottle, press down evenly and release the pump 5 times. The bottle is now ready to use.
• To use this nose spray, gently blow your nose. Sit up straight or stand and tilt your head forward slightly. Place the tip of the spray container into the nose. Be sure to point the container away from the center of your nose. Breathe gently through the nostril and squeeze the spray container. If your dose requires 2 sprays, repeat the process for your other nostril. Replace the clear plastic cover after each use.
• Do NOT use Algikey spray for more than 5 days. Algikey spray is not for the treatment of mild to moderate or chronic pain (eg, headache).
• Avoid contact with the eyes. If you get Algikey spray in your eyes, rinse it out with water. If eye irritation persists for more than 1 hour, contact your doctor.
• Each bottle contains 1 day's supply of Algikey spray. Discard each bottle within 24 hours of opening it, even if it still contains some unused medicine.
• If you miss a dose of Algikey spray and you are taking it regularly, take it as soon as possible. If it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Algikey spray.

Uses of Algikey in details

Use: Labeled Indications

Pain, moderate to moderately severe: Short-term (up to 5 days) management of moderate to moderately severe pain in adults that requires analgesia at the opioid level.

Off Label Uses

Migraine

Data from a prospective, randomized, double-blind, double-dummy, placebo and active comparator, crossover, non-inferiority trial suggests that intranasal Algikey may be beneficial for acute abortive treatment of migraine in patients with a history of episodic migraines for at least 1 year.

Algikey description

A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of morphine. It also has a depressant action on the cough center and may be given to control intractable cough associated with terminal lung cancer. Algikey is also used as part of the treatment of dependence on opioid drugs, although prolonged use of methadone itself may result in dependence. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)

Algikey dosage

Carefully consider the potential benefits and risks of Algikey tromethamine tablets and other treatment options before deciding to use Algikey tromethamine tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals. In adults, the combined duration of use of IV or IM dosing of Algikey tromethamine and Algikey tromethamine tablets is not to exceed 5 days. In adults, the use of Algikey tromethamine tablets is only indicated as continuation therapy to IV or IM dosing of Algikey tromethamine.

Transition from IV or IM dosing of Algikey tromethamine (single- or multiple-dose) to multiple-dose Algikey tromethamine tablets:

Patients age 17 to 64: 20 mg PO once followed by 10 mg q4 to 6 hours prn not > 40 mg/day

Patients age ≥ 65, renally impaired, and/or weight < 50 kg (110 lbs): 10 mg PO once followed by 10 mg q4 to 6 hours prn not > 40 mg/day

Note:

Oral formulation should not be given as an initial dose.

Use minimum effective dose for the individual patient.

Algikey interactions

What other drugs will affect Algikey?

Algikey slightly reduces the plasma protein-binding of warfarin. In vitro studies indicate that at therapeutic concentration of salicylate, the binding of Algikey reduces from approximately 99.2-97.5%; representing a potential 2-fold increase in unbound plasma Algikey levels. Algikey has been reported to reduce the diuretic response to furosemide in normovolemic individuals by approximately 20%.

Concomitant administration of Algikey and probenecid results in decreased clearance of Algikey and significant increase in Algikey plasma levels (approximately 3-fold increase), and there is an increase of approximately 2-fold in terminal half-life.

Increase in plasma lithium concentration due to inhibition of renal lithium clearance has been reported with some NSAIDs. There have been some reports of increased lithium plasma levels with Algikey also.

There have been reports of a possible interaction of Algikey and nondepolarizing muscle relaxants, which lead to apnea. Concomitant use of Algikey and angiotensin-converting enzyme inhibitors may increase the risk of renal impairment, particularly in volume-depleted patients.

Very few cases of seizure have been reported with concomitant use of Algikey and antiepileptic drugs (phenytoin, carbamazepine). There have been reports of hallucinations when Algikey is concomitantly used with psychoactive drugs (fluoxetine, thiothixene, alprazolam).

Laboratory Tests: Algikey inhibits platelet aggregation and may prolong bleeding time.

Food: Food reduces the rate but not the extent of absorption.
