[trade name (it was marketed as the "heroine" of analgesic drugs)]


/her·o·in/ (her´o-in) diacetylmorphine; a highly addictive morphine derivative; the importation of heroin and its salts into the United States, as well as its use in medicine, is illegal.


Etymology: Ger, heroine, originally trademark for diacetylmorphine
a morphine-like drug with no currently acceptable medical use in the United States. Heroin is included in Schedule I of the Controlled Substances Act of 1970. Like other opium alkaloids, it can produce analgesia, respiratory depression, GI spasm, and physical dependence. It produces its major effects on the central nervous system and bowel and alters the endocrine and autonomic nervous systems. Heroin, which loses much of its analgesic power when taken orally, is more powerful than morphine and acts more rapidly. Repeated use of this drug produces tolerance to most of the acute opioid effects; physical dependence develops concurrently with tolerance. Withdrawal from heroin after relatively few exposures commonly produces acute abstinence syndrome. Withdrawal signs are usually observed shortly before the next planned dose and commonly include anxiety, restlessness, irritability, and craving for another dose. Other withdrawal signs that may appear 8 to 15 hours after the last dose include lacrimation, perspiration, yawning, and restless sleep. On awakening from such sleep the severely addicted heroin user may experience withdrawal signs, such as vomiting, pain in the bones, diarrhea, convulsions, and cardiovascular collapse. Withdrawal signs usually peak at between 36 and 48 hours and gradually subside during the following 10 days. Methadone is commonly used as a substitute drug in the treatment of heroin addiction (methadone maintenance therapy). Also called diacetylmorphine.

Patient discussion about heroin

Q. What are the effects of heroin addiction? I just found out that one of my block mates has been using heroin to keep her up all night just so she can study for our exams. But I don't think it's doing her any good. I asked her if she wanted to talk about it, but she refused. I would like to help her get out of heroin addiction while she still can.

A. oh one my favorite ones for sure. the up side is nice sleepy time, complete numbing of unwanted emotion & sense of well being. the bad side it's unhealthy. i don't know how much it's the dope or the cut but that shit is hell on the g.i. tract, liver & kidneys. prolonged use over numerous years of time really change the brains factory specs. in other words physical withdrawl hell say two, three, four weeks or so (varies among bodys) but the psychological aspect can be a long suffered challenge to deal with. let's just say in my opinion one would really have to come to an internal & external relationship with life that they decide that their time to go straight & stay straight has arrived. & i mean after the detoxification process mentioned, that the same conviction, the same resolve remains.
