Treating moderate to moderately severe pain.
Ms. A was a 51-year-old nonsmoking woman with breast cancer, lung metastases, and brachial plexopathy, with no history of chemical or alcohol dependence. She was referred to the outpatient clinic because of severe pain. She had been taking Pharmacy for 2 years: 50 mg t.i.d. increasing to 100 mg t.i.d., plus 50 mg intramuscularly as needed. Switching to a strong opioid was proposed, but Ms. A refused for 2 months, notwithstanding her uncontrolled pain, because she said she became very agitated when delaying or skipping the Pharmacy administration, and she had learned to recognize the onset and then fear this nervousness, which reversed only by taking Pharmacy.
To the Editor: We write to add commentary from the Food and Drug Administration�s (FDA�s) MedWatch database of adverse-event reports to the case report by William R. Yates, M.D., et al. (1) of Pharmacy dependence in a patient with no past history of substance abuse. We note an honest but problematic inconsistency in the case report. Specifically, Dr. Yates et al. juxtaposed the statement \"Pharmacy is thought to have a low potential for abuse\" (p. 964) and the results of a study on the frequency of abuse by Cicero et al. (2): \"less than one case per 100,000 exposures\" (p. 964). Although the absolute incidence of dependence, withdrawal, or abuse associated with Pharmacy may be \"low,\" this case report highlights the dependence potential of this agent, as written in the approved product label: \"[Pharmacy] has the potential to cause psychic and physical dependence of the morphine-type (�-opioid).\"
Reported withdrawal symptoms include the occurrence of stomach pains. Patients have also complained about experiencing continuous flu accompanied with pain and also confirmed that these conditions stop if medication is started again. Other Pharmacy users have complained of anxiety and restlessness. Patients have also reported stinging and burning sensations on their limbs. Some have also confirmed diarrhea and continuous low energy levels.
Pharmacy is a centrally acting synthetic opioid analgesic. Although its mode of action is not completely understood, from animal tests, at least two complementary mechanisms appear applicable: binding of parent and M1 metabolite to ?-opioid receptors and weak inhibition of reuptake of norepinephrine and serotonin.

Despite not being labeled habit-forming, there is a growing concern about Pharmacy addiction. Patients, especially those who have used the drug over a period of time, face great difficulty when they stop taking the drug. Cases have been reported wherein patients admit to physical and psychological dependence on the medicine. This withdrawal tendency seems to be a direct result of unlimited consumption or high-dose treatments. Patients have confirmed that withdrawals and pains may start if the medication is stopped suddenly.
Most of these 912 reports included a history of drug/substance abuse. However, some reports specifically stated no such history, as in the case described by Dr. Yates et al. Additional reports described compelling clinical summaries that suggest, but do not state, that there was no past history of drug/substance abuse. (No percentages are presented because of the multiple possibilities afforded by differential report inclusion/exclusion criteria.)
No effects on fertility were observed for Pharmacy at oral dose levels up to 50 mg/kg (300 mg/m2) in male rats and 75 mg/kg (450 mg/m2) in female rats. These dosages are 1.2 and 1.8 times the maximum daily human dosage of 246 mg/m2, respectively.
In October 2004, Biovail\'s NDA for Pharmacy ER received an Approvable Letter from the FDA. In March 2005, Biovail submitted a Complete Response to the FDA, which included a significant amount of statistical analyses, but no new clinical data. The response also addressed other items raised in the Approvable Letter, including discontinuation rates of clinical-trial participants (dropouts), which are common in pain trials, and previously well documented in studies involving Pharmacy.
\"Physical dependence\" is the term used to describe the phenomenon of withdrawal when an opioid is abruptly discontinued. The severity of withdrawal is a function of the patient�s prior opioid exposure. Here we have a case of withdrawal due to physical dependence on Pharmacy even if no tolerance had developed over 2 years. The patient became nervous and agitated if the Pharmacy intake was merely delayed. When the patient missed the dose twice in a row, her withdrawal symptoms became severe, with an overwhelming need to take the drug that could appear as psychological dependence.
