Lacomin

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. Lacomin 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)

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

Acute Pain in Adult Patients

Lacomin 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 Lacomin Tromethamine, and oral Lacomin Tromethamine is to be used only as continuation treatment, if necessary.

The total combined duration of use of Lacomin Tromethamine injection and oral Lacomin 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 Lacomin Tromethamine therapy is not to exceed 5 days.

Lacomin 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 Lacomin Tromethamine injection dosage range with low doses of narcotics prn, unless otherwise contraindicated. Lacomin Tromethamine injection and narcotics should not be administered in the same syringe.

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

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

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

Carefully consider the potential benefits and risks of Lacomin tromethamine tablets and other treatment options before deciding to use Lacomin 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 Lacomin tromethamine and Lacomin tromethamine tablets is not to exceed 5 days. In adults, the use of Lacomin tromethamine tablets is only indicated as continuation therapy to IV or IM dosing of Lacomin tromethamine.

Transition from IV or IM dosing of Lacomin tromethamine (single- or multiple-dose) to multiple-dose Lacomin 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.

Do not shorten dosing interval of 4 to 6 hours.

Total duration of treatment in adult patients: the combined duration of use of IV or IM dosing of Lacomin tromethamine and Lacomin tromethamine tablets is not to exceed 5 days.

What is the most important information I should know about Lacomin?

Lacomin Tromethamine is contraindicated in patients with previously demonstrated hypersensitivity to Lacomin Tromethamine.

Lacomin Tromethamine is contraindicated in patients with active peptic ulcer disease, in patients with recent gastrointestinal bleeding or perforation and in patients with a history of peptic ulcer disease or gastrointestinal bleeding.

Lacomin Tromethamine should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients.

Lacomin Tromethamine is contraindicated as prophylactic analgesic before any major surgery.

Lacomin Tromethamine is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery.

Lacomin Tromethamine is contraindicated in patients with advanced renal impairment or in patients at risk for renal failure due to volume depletion.

Lacomin Tromethamine is contraindicated in labor and delivery because, through its prostaglandin synthesis inhibitory effect, it may adversely affect fetal circulation and inhibit uterine musculature, thus increasing the risk of uterine hemorrhage.

Lacomin Tromethamine inhibits platelet function and is, therefore, contraindicated in patients with suspected or confirmed cerebrovascular bleeding, hemorrhagic diathesis, incomplete hemostasis and those at high risk of bleeding.

Lacomin Tromethamine is contraindicated in patients currently receiving aspirin or NSAIDs because of the cumulative risks of inducing serious NSAID-related adverse events.

The concomitant use of Lacomin Tromethamine and probenecid is contraindicated.

The concomitant use of Lacomin Tromethamine and pentoxifylline is contraindicated.

Lacomin Tromethamine injection is contraindicated for neuraxial (epidural or intrathecal) administration due to its alcohol content.

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

• Lacomin spray comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Lacomin spray refilled.
• Do not take Lacomin 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 Lacomin spray for more than 5 days. Lacomin spray is not for the treatment of mild to moderate or chronic pain (eg, headache).
• Avoid contact with the eyes. If you get Lacomin 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 Lacomin spray. Discard each bottle within 24 hours of opening it, even if it still contains some unused medicine.
• If you miss a dose of Lacomin 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 Lacomin spray.

What other drugs will affect Lacomin?

Should be used with caution in patients undergoing anticoagulant therapy and use must be strictly monitored. Combination of Lacomin tromethamine and other NSAIDs is not recommended because it would increase the risk of side effects.

Warfarin: Protein-binding of warfarin may be decreased slightly from 99.5-99.3%. It does not significantly change the pharmacokinetics or pharmacodynamics profile. Protein-binding of Lacomin does not change.

Heparin: Prolongs average bleeding time (placebo: 5.1 min; heparin: 6 min; heparin + Lacomin: 6.4 min).

Digoxin: Protein-binding of digoxin and Lacomin does not change.

Salicylate: Protein-binding of Lacomin was decreased from 99.2-97.5% which would represent a potential 2-fold increase in plasma concentrations of unbound drug.

Ibuprofen, Naproxen, Piroxicam, Acetaminophen, Phenytoin and Tolbutamide: Protein-binding does not change.

Furosemide: Reduced diuretic response 20% (mean sodium and urinary output decreased 17%).

Probenecid: Results in decreased clearance of Lacomin and significant increases in Lacomin plasma levels (Total AUC increased ±3-folds from 5.4-17.8 mcg/hr/mL, terminal t_½ increase of ±2-fold from 6.6-15.1 hrs. Concomitant use of Lacomin and probenecid is contraindicated.)

Lithium: Inhibition of renal lithium clearance leading to an increase in plasma lithium concentration.

Methotrexate: Methotrexate clearance is decreased, enhancing the toxicity of methotrexate. The effect of methotrexate on Lacomin clearance has not been studied.

Nondepolarizing Muscle Relaxants: Concomitant use of Lacomin and muscle relaxants has not been studied so it must be used with caution.

ACE Inhibitors: Renal impairment will be increased especially in volume-depleted patients.

Antiepileptic Drugs (Phenytoin, Carbamazepine): Convulsion attacks occurred (sporadic cases).

Psychoactive drugs (Fluoxetine, Tiotixene, Alprazolam): Hallucinations.

Morphine: No detrimental interactions are observed. Do not mix Lacomin and morphine in the same syringe.

There are no reports of interactions between Lacomin and antibacterials, antiemetics, laxatives, sedative, anxiolytics, corticosteroids, bronchodilators or hormones.

No evidence (in animal or human studies) shows that Lacomin induces or inhibits hepatic enzymes capable of metabolizing itself or other drugs.
