The dopamine agonists – bromocriptine, amantadine, mazindol – this is conclusively disproved now. Amantadine hasn’t done as well as bromocriptine and bromocriptine has had side effects and has had some negative trials now too. So the answer on do we have a treatment for cocaine? No. All we have is longitudinal treatment and then relapse prevention. Isolating from the cues. Reintroducing the cues as the patient succeeds to give them a chance to bolster their techniques of thinking about the consequences, reminding themselves of the spouse’s wishes to stay clean and various counseling techniques. Stress. Coping with stress, learning to pamper one’s self in ways other than the most immediate gratification. These are things our patients really don’t know how to do.
You probably are seeing all the advertisements for tramadol, Ultram. A new pain agent, nonsteroidal but it’s not one of the NSAIDs. It’s a nonopiate analgesic but there is some concern that it can trigger relapse so we have to be careful with it. I haven’t seen a big market in Ultram abuse but there is actually a study assessing that rationally. So far, so good. One of the physiologic effects of the opiates that is helpful to remember for the boards but also for looking at patients in emergency situations, remember that aside from the analgesia and the rush and the euphoria of opioids they also produce smooth muscle inhibition and that’s down at the bottom of page 284. You might just want to put a check mark or a star there. That helps you think of several other things without having to memorize all of them.
Tramadol online - Tramadol is a non-opioid pain relief medication that is meant to help alleviate moderate to moderately severe pain. Tramadol is a synthetic analgesic, not an anti-inflammatory, which means that people who cannot take anti-inflammatories due to the side effects can often take Tramadol to help relieve their pain.
Smooth muscle inhibition. So the pinpoint pupils in patient’s eyes when they’re intoxicated with heroin, that’s because the smooth muscle that opens the iris for a full pupil is being relaxed. So that smooth muscle inhibition allows the pupil to close down that tight. It’s also responsible for some of the initial nausea and vomiting that people have sometimes when they try codeine for the first time. Heroin does it too, by the way. The same thing is true of withdrawal. If smooth muscle inhibition is part of the intoxication what do you think happens in withdrawal? You get smooth muscle hyperactivation so you get all nausea and diarrhea and the loss of appetite and the pupils get enlarged.

The mu-opioid receptor system is the primary analgesic receptor system. It’s anti nociception. Anti nociception means you don’t feel pain. You can feel pressure but you don’t feel pain when these sites are occupied. Heroin, morphine, methadone, the m’s go with mu. The delta receptors are also supportive for analgesia and the akephalines have the better binding for this. So we have these three major systems. The kappa system you know about. Talwin, pentazocine produces analgesia there but it is also associated with a risk for dysphoria and Talwin is contraindicated in a patient who has mu-opioid dependence – heroin, morphine or methadone. Contraindicated because it will trigger a dysphoric reaction.
