Quantification of missing prescriptions in commercial claims databases: results of a cohort study. Comparison of respiratory effects of tramadol and oxycodone. There is no evidence that tramadol provides superior pain relief compared to other weak opioids, such as codeine. Tramadol is associated with less risk of respiratory depression and constipation than codeine, but has an increased risk of serotonin toxicity. There are no robust studies suggesting that tramadol provides either more or less analgesia than codeine or dihydrocodeine.

People who are poor CYP2D6 metabolisers are likely to experience reduced analgesia with tramadol (and codeine) and ultra-rapid metabolisers may be more sensitive to adverse effects. Modified-release tramadol may be associated with fewer adverse effects in some patients. Tramadol is sometimes prescribed as a second-line medicine to patients with neuropathic pain,8 although the evidence supporting this practice is weak.

In this scenario, it may be reasonable to select tramadol, in preference to codeine or dihydrocodine, if a Step 2 analgesic is required. Tramadol may have less potential for misuse and dependency than other opioids as it is an atypical analgesic, however, the same prescribing cautions should be applied to tramadol as to other opioids to minimise the risk of inappropriate use.

However, a slower withdrawal may be considered for patients who have been taking frequent, higher doses. Ensure that when tramadol is withdrawn (either abruptly or tapered), analgesic cover is provided by concurrent use of paracetamol or a NSAID, until the pain is manageable without pharmacological treatment.

These pills, the world has been told, are safer than the OxyContins, the Vicodins, the fentanyls that have wreaked so much devastation. The man-made opioid was touted as a way to relieve pain with little risk of abuse. Unlike other opioids, tramadol flowed freely around the world, unburdened by international controls that track most dangerous drugs.

But abuse is now so rampant that some countries are asking international authorities to intervene. This story was produced with support from the Pulitzer Center on Crisis Reporting. International regulations make narcotics difficult to get in countries with disorganized health systems, the company says, and adding tramadol to the list would deprive suffering patients access to any opioid at all.

Tramadol is available in war zones and impoverished nations because it is unregulated.
