Oxycodone ER Side Effects - for the Professional

Oxycodone ER

The safety of oxycodone hydrochloride extended-release tablets was evaluated in double-blind clinical trials involving 713 patients with moderate to severe pain of various etiologies. In open-label studies of cancer pain, 187 patients received oxycodone hydrochloride extended-release tablets in total daily doses ranging from 20 mg to 640 mg per day. The average total daily dose was approximately 105 mg per day.

Serious adverse reactions which may be associated with oxycodone hydrochloride extended-release tablet therapy in clinical use are those observed with other opioid analgesics, including respiratory depression, apnea, respiratory arrest, and (to an even lesser degree) circulatory depression, hypotension or shock.

The non-serious adverse events seen on initiation of therapy with oxycodone hydrochloride extended-release tablets are typical opioid side effects. These events are dose-dependent, and their frequency depends upon the dose, the clinical setting, the patient’s level of opioid tolerance, and host factors specific to the individual. They should be expected and managed as a part of opioid analgesia. The most frequent (>5%) include: constipation, nausea, somnolence, dizziness, vomiting, pruritus, headache, dry mouth, sweating, and asthenia.

In many cases the frequency of these events during initiation of therapy may be minimized by careful individualization of starting dosage, slow titration, and the avoidance of large swings in the plasma concentrations of the opioid. Many of these adverse events will cease or decrease in intensity as oxycodone hydrochloride extended-release tablet therapy is continued and some degree of tolerance is developed.

Clinical trials comparing oxycodone hydrochloride extended-release tablets with immediate-release oxycodone and placebo revealed a similar adverse event profile between oxycodone hydrochloride extended-release tablets and immediate-release oxycodone. The most common adverse events (>5%) reported by patients at least once during therapy were:
