Targiniq ER (oxycodone hydrochloride and naloxone hydrochloride) Extended Release is a combination of an opioid agonist and an opioid antagonist used for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Common side effects of Targiniq ER include:

  • nausea,
  • headache,
  • constipation,
  • abdominal pain,
  • vomiting,
  • itching,
  • anxiety,
  • insomnia,
  • back pain, or
  • drug withdrawal syndrome.

Less common side effects of Targiniq ER include:

The starting dose of Targiniq ER for patients who are not opioid tolerant is 10 mg/5 mg orally every 12 hours. Targiniq ER may interact with other CNS depressants including sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and alcohol; skeletal muscle relaxants, pentazocine, nalbuphine, butorphanol, buprenorphine, diuretics, and anticholinergics. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or plan to become pregnant before using Targiniq ER. This drug is generally not recommended for use during pregnancy. It may harm a fetus. Babies born to mothers who have used Targiniq ER while pregnant may suffer withdrawal symptoms after birth. Oxycodone passes into breast milk. Using this drug while breastfeeding may cause undesirable effects in a nursing infant. Consult your doctor. Withdrawal symptoms may occur if you suddenly stop taking this medication.

SIDE EFFECTS

The following serious adverse reactions are described elsewhere in the labeling:

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

A total of 2,396 patients were treated in controlled and open-label clinical studies with TARGINIQ ER. Seven hundred and ninety-four of these patients (33%) were treated for approximately six months and 621 (26%) were treated for approximately one year.

TARGINIQ ER may increase the risk of serious adverse reactions such as those observed with other opioid analgesics, including respiratory depression, apnea, respiratory arrest, circulatory depression, hypotension, or shock [see OVERDOSAGE].

Commonly Observed Treatment-Emergent Adverse Reactions In A Clinical Study With TARGINIQ ER In Opioid-Experienced Patients With Uncontrolled Moderate To Severe Chronic Low Back Pain

The safety data described in Table 4 below are based on a 12-week, randomized, double-blind, placebo-controlled clinical trial in opioid-experienced patients with moderate to severe chronic low back pain. This trial included 1,095 TARGINIQ ER-treated patients in an open-label titration period, and 298 TARGINIQ ER-and 302 placebo-treated patients in a double-blind treatment period. The mean age was 52 years old; 55% were female, and 45% were male; 74% were Caucasian, 22% were Black, and 11% were Hispanic.

The most common treatment-emergent adverse reactions (reported by ≥ 5% of TARGINIQ ER subjects) during the open-label or double-blind periods were nausea and vomiting.

The most common reason for discontinuation during the open-label period due to treatment-emergent adverse reactions (reported by ≥ 1% of subjects) was nausea (2%).

The most common reason for discontinuation during the double-blind period due to treatment-emergent adverse reactions (reported by ≥ 1% of subjects with TARGINIQ ER or placebo) was drug withdrawal syndrome ( < 1% vs. 1%), respectively.

The incidence of treatment-emergent adverse reactions reported by ≥ 2% of subjects in a clinical trial comparing TARGINIQ ER with placebo is shown in Table 4 below:

*Percentages in the table are based on adverse reaction reports of Drug Withdrawal Syndrome in the key efficacy and safety study. In addition to the adverse reaction reports, an independent Adjudication Committee identified additional subjects with possible drug withdrawal syndrome, resulting in a total (adverse reactions plus adjudicated cases) of 2% of subjects in the Open-Label Period, and in the Double-Blind Period 4% of subjects treated with TARGINIQ ER and 2% treated with placebo.

In a clinical trial, the following adverse reactions were reported in patients treated with TARGINIQ ER with an incidence between ≥ 1% and < 2%:

Eye disorders: lacrimation increased

General disorders and administration site conditions: fatigue

Infections and infestations: influenza

Injury, poisoning, and procedural complications: fall

Musculoskeletal and connective tissue disorders: arthralgia

Nervous system disorders: dizziness, sinus headache, somnolence

Psychiatric disorders: drug abuse

Skin and subcutaneous tissue disorders: pruritus, rash, cold sweat

Vascular disorders: hot flush, hypertension

Postmarketing Experience

The following most frequently reported adverse reactions have been identified during post-approval use of oxycodone/naloxone extended-release tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Gastrointestinal Disorders: abdominal pain, constipation, diarrhea, nausea, and vomiting

General Disorders and Administration Site Conditions: drug withdrawal syndrome, fatigue, pain, malaise, and drug ineffective

Injury, Poisoning, and Procedural Complications: inadequate analgesia

Neoplasms Benign, Malignant, and Unspecified (including cysts and polyps): malignant neoplasm progression

Nervous System Disorders: dizziness, headache, tremor, and somnolence

Psychiatric Disorders: restlessness, confusional state, and anxiety

Respiratory, Thoracic, and Mediastinal Disorders: dyspnea

Skin and Subcutaneous Tissue Disorders: hyperhidrosis and pruritus

Serotonin syndrome: Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

Adrenal insufficiency: Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use.

Anaphylaxis: Anaphylaxis has been reported with ingredients contained in TARGINIQ ER.

Androgen deficiency: Cases of androgen deficiency have occurred with chronic use of opioids [see CLINICAL PHARMACOLOGY].
