Oxycodone Extended-Release (ER) 20mg

Oxycodone is a semisynthetic opiate partial agonist derived from the opioid alkaloid, thebaine. Oxycodone is used to control moderate to severe pain. 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).

Comparative Dissoluion Profile of Oxycodone From Test

(FAROXY SR. 40mg FC. Tablets, Endofar) Vs. Reference

(OLBETESR. 40mg FC. Tablets, Tecnimede, Canada) Drugs

Faroxy-ER 40mg (manufactured by Endofar pharmaceutical Company) and Olbete®-SR 40mg (manufactured by Tecnimede in Canada) according to FDA guidance for industry entitled “Bioavailability and Bioequivalence studies submitted in NDAs or INDs_General considerations” were bioequivalent. Also, it is worth to remark that this study was approved by Local Food and Drug Administration.

Clinical Research

Oral OXYCODONE is as effective as IV Morphine Sulfate (MS) in Management of Acute Pain Following limb trauma

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

Calculating Total Daily Dose of OXYCODONE for Safer Dosage

Calculating total daily doses of opioids is important to appropriately and effectively prescribe, manage, and taper opioid medications. Patients prescribed higher opioid dosages are at higher risk of overdose death. The daily dose calculating of new opioid 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.These dose conversions are estimated and cannot account for all individual differences in genetics and pharmacokinetics.
