ORIGINAL: BoiJen http://www.drugbank.ca/drugs/DB00295 You'll find it under toxicity. Here's another one by a doctor playing with drug combination: http://works.bepress.com/kelvin_chan/28/ Sorry, I don't have your precious PDR. You'll notice that most ER doctors don't go around carrying them while ordering drugs for a patient. In fact, the only type of people I've know to solely rely on the PDR in such a religious manner as you have thompson are paramedics who don't actually know their shit. Just sayin.... boi BTW: The LD50 notation in mice and rats is significant as it's the test basis of human consumption. To ignore that fact and simply stating "That doesn't say what the LD50 is in humans" is the most asinine thing I've read in a long Goddamned time. It shows ignorance of the scientific process used to protect people from over dosing repeatedly and really seems to be your only effort at trying to prove your case. Just because you seem to want to ignore the facts doesn't make them less true. Why do you think they put LD50 in the PDR? This is the quote from the toxicity section of your cite. You will note that it takes 600mg/kg to kill a rat but only 120-250mg to kill a human. quote:
LD50 = 461 mg/kg (rat, oral), 600 mg/kg (mouse, oral). Human lethal dose by ingestion is 120-250 mg of morphine sulfate. Symptoms of overdose include cold, clammy skin, flaccid muscles, fluid in the lungs, lowered blood pressure, "pinpoint" or dilated pupils, sleepiness leading to stupor and coma, slowed breathing, and slow pulse rate. Also from the same site with a link to the PDR:quote:
What is the usual dosage? Return to top The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval. Adults: MS Contin is usually taken every 12 hours at doses that range from 15 milligrams (mg) to 200 mg per dose. Your individual dose depends on if you have taken another narcotic pain medication in the past or are switching from another pain medication to MS Contin. Your dose is also determined by your doctor based on the type of pain medication you have taken in the past and its dose. MS Contin 100 and 200 mg tablets are only to be taken by patients who are tolerant of daily doses of morphine of 200 mg and greater for the 100 mg tablet or 400 mg and greater for the 200 mg tablet. Here you will note that the normal dosage is in excess of what your cite claims is LD50. You will also note that this morphine tablet comes also in a 400mg tablet. There is a reason they call that book the Physicians Desk Reference.
