Oxycodone Extended-Release (ER) 40mg

Oxycodone is a semisynthetic opiate partial agonist derived from the opioid alkaloid, thebaine. In Addition, Oxycodone 40 mg is used to control moderate to severe pain. Also, It is available as immediate-release tablets (IR), extended-release (ER), and in combination with acetaminophen. Oxycodone undergoes low first-pass metabolism and has a higher bioavailability (60%-87%) compared with morphine. It is slightly more potent than morphine (Oral Oxycodone is roughly 1.5 times more potent than oral morphine).

Therapeutic Fields​

Fast Relief of Acute Pain

Acute pain relief

Fast onset of action

For initial dose in opioid-naive patients

Clinical Research

Oral Oxycodone 40 mg is as effective as IV Morphine Sulfate (MS) in the Management of Acute Pain Following limb trauma

Based on a clinical trial performed in 2018 there was no significant difference between the two groups regarding the decrease in pain within 0, 30, and 60 minutes after administration of either 5mg IV MS or 5mg oral oxycodone. Drowsiness was reported more frequently in the MS group after 30 minutes. Eight participants asked for rescue analgesia in the MS group, while only one patient asked for more analgesia in Oxycodone 40 mg. Other adverse effects were similar in both groups.​

Calculating Total Daily Dose of Oxycodone 40 mg for Safer Dosage

Calculating total daily doses of opioids is important to appropriately and effectively prescribe, manage, and taper opioid medications. Moreover, Patients prescribed higher opioid dosages are at higher risk of overdose death. The daily dose calculation of new opioids is as follows

Total Daily Dose of New Opioid

The obtained total daily dose divided by 2 is for OXYCODONE ER and divided by 4 is for OXYCODONE IR. Therefore, These dose conversions are estimated and cannot account for all individual differences in genetics and pharmacokinetics.

Dosing

Infants ≤ 6 months:

Oral Initial dose: 0.025 to 0.05 mg/ kg/ dose every 4 to 6 hours as needed.

Infants> 6 months, Children:

Patient weight <50 kg: Initial dose: 0.1 to 0.2 mg/ kg/ dose every 4 to 6 hours as needed.

Adolescents:

Patient weight 2:50 kg. Initial dose: 5 to 10 mg every 4 to 6 hours as needed.

Administration

Onset

5 – 15 min

Half-life
