Brain, lungs, liver, kidneys, spleen); also accumulates in muscle (due to large mass) and fat (esp. if lipophilic, eg. Fentanyl) Metabolism Converted to polar metabolites via 1st pass metabolism (90% hepatic) when PO, variation in 1st pass between people. Also occurs in brain and kidneys

However, they can also cause a number of side effects and complications. Therefore, the treating provider must assess each patient individually to determine the best type of medication for pain management. Potential complications from analgesics:2. Opiate Side Effects and Other Information Fentanyl Less hypotension than with morphine.

Fentanyl is highly lipophilic and is well distributed beyond the vascular system, with a large apparent volume of distribution. Animal data have shown that, following absorption, fentanyl is rapidly distributed to the brain, heart, lungs, kidneys and spleen followed by a slower redistribution to muscles and fat.

Fentanyl is a potent opioid analgesic chemically related to pethidine with affinity mainly for the µ-receptor present in the brain and spinal cord. This application is for fentanyl citrate presented as a nasal spray for nasal administration. The submission proposes registration of the following dosage forms and strengths:

Like heroin and morphine, fentanyl works by binding to opioid receptors in the brain. This causes higher levels of dopamine in the body, resulting in a euphoric, relaxed state. Because of these desirable effects, fentanyl was widely abused in the past. It is still abused presently, though not with the same rate due to …

However, a larger dose will be more likely to exceed the therapeutic window, and possible cause toxic effects. For example, figure 12 shows the biophase concentrations after two different bolus doses of fentanyl designed to achieve the high and low edges of the therapeutic window for supplementing an induction with thiopental.

Naloxone is an opioid antagonist drug, which means it displaces opioids from opioid receptors in the brain. When administered, it reverses the effects of opioids, including the the respiratory depression that occurs during an opioid overdose.
