Olanzapine at a dose that had an antiemetic effect (0.03 mg/kg) did not induce catalepsy or hyperglycemia, and had no effect on the morphine-induced release of dopamine or inhibition of gastrointestinal transit. Olanzapine also inhibited thermal hyperalgesia and completely alleviated sleep disturbances, suggesting that olanzapine may be useful for the treatment of morphine-induced emesis . Exhibit 5-1 lists the most common side effects experienced by patients treated with injectable naltrexone. As when using oral naltrexone, patients should contact their physician if they experience signs or symptoms of liver disease (see Exhibit 4-6). Naltrexone is an opioid antagonist, so individuals who are opioid dependent may experience opioid withdrawal.

Patients should tell their practitioner about any side effects that are bothersome, or do not go away.

I had heard from my doctor and others that the side effects I’d experienced were pretty normal, and would wear off if I kept taking it. I figured that, the first time or two I tried it, I was just being a pansy who didn’t want to quit drinking. I experienced some of the same symptoms throughout the night on Friday, but I was able to muscle through them and do some work anyway.

A recent finding has suggested that a variant in a gene encoding for the mu opiate receptor in the opiate neurotransmitter system may predict response to naltrexone treatment in people dependent on alcohol (Anton et al., 2008). This finding suggests that OPRM1 genotyping may be a useful procedure for improving identification of those patients most likely to benefit from naltrexone treatment for alcohol dependence. It also suggests that clinicians should not become discouraged if the first patients they prescribe naltrexone for do not find it beneficial.

Since these drugs are less efficacious in blocking the KOR relative to the MOR, higher doses than typically used seem to be necessary. In addition to the opioid receptors, naltrexone binds to and acts as an antagonist of the opioid growth factor receptor and toll-like receptor 4 and interacts with high- and low-affinity binding sites in filamin-A . It is said that very low doses of naltrexone ( The interactions of naltrexone with FLNA and TLR4 are claimed to be involved in the therapeutic effects of low-dose naltrexone. By itself, naltrexone acts as an antagonist or weak partial agonist of the opioid receptors. In combination with agonists of the MOR such as morphine however, naltrexone appears to become an inverse agonist of the MOR.

I also haven’t had any reduction in craving or drinking though. I’m taking my pill 1 hour before drinking and it doesn’t seem to do much for me. On naltrexone, you’re able to drink without any problems. The idea is that it works subtly in the background to reverse the addictive wiring in your brain that causes the irresistible urges to drink.
