ABSTRACT OF THE DISCLOSURE
Quaternary derivatives of noroxymorphone are used to prevent or relieve nausea and emesis associated with the use of narcotic analgesics without interfering with the analgesic activity of the drugs. A particularly preferred compound is methylnaltrexone. The compound is administered in a concentration between 0.05 mg/kg and 1.0 mg/kg prior to or concurrently with the administration of the narcotic analgesic.

Description
~3~ 3 ~0355--99 OUATERNARY DERIVATIVES OF NOROXYMORPHO
~HICH RELIEVE NAUSEA AND EMESIS
The administration of therapeutic doses of morphine and other clinically useful narcotie analgesies is often aecompanied by unpleasant side effects on the gas-tro-intestinal system. For instance, morphine and related opiates such as meperidine and methadone may reta~d intestinal mobility by causing con-traetions of -the small bowel eireular smooth musele.
Morphine and related narcoties may also induce nausea and increased mobility of the gastro-intes-tinal tract resulting in emesis or vomiting~ These side effects are eaused by direet stimulation of the chemoreeeptor trigger zone for emesis in the area postrema of the medulla. (Goodman and Bilman, The Pharmaeologieal Basis of Theraneu~ics, p. 502 [6`th ed. 1980]). Studies have shown that morphine and other nareoties eause emesis in dogs. For example, Wang and Glaviano, JPET 111:329-334 ~9143~, reported that administration of 0.5 mg/kg of morphine intravenously to 12 dogs resulted in emesis in 9 dogs within an average of 2.

1 morphine was administered intramuscularly to 13 dogs, 12 of them vomited within an average time of 3.5 minutes.
U. S. Patent No. 4,176,186 to myself and others disclosed treatment of intestinal immobility associated with the use of narcotic analgesics through the administration of guaternary derivatives of noroxymorphone.'' It has now been discovered that the same compounds are also useful fox the treatment, ~oth prophylactic.and therapeutic,'of the nausea and vomiting associated with the administration of these drugs.
'~'According to the invention, therefore, nausea and vomiting by warm-blooded animals receiving morphine and lS related opiates~ meperidine,-methadone or the like, may be prevented ~r relieved by the administration of methylnaltrexone or other quaternary derivatives of noroxymorphone represented by the formula:

` ~`b wherein ~/0 R is allyl or a related radical such as chloroallyl, cyclopropyl-methyl Gr propargyl, and X is the anion of an acid, especially a chloride, bromide, iodide or methylsulfate anion.
These compounds are administered to the animal either prior to or . simultaneously with the administration of the narcotic analgesic. They may be ~3~
-- 3 ~
admini~-tered either enterally or paren-terally. There has no-t been observed any interference with the analgesic activi-ty of the opi~tes.
As used herein, unless the sense of the usage indicates otherwise, the term l'morphine" refers to any narcotic analgesic.
This invention relates to the use of quaternary derivatives of noroxymorphone to prev~nt or relieve nausea and vomiting associated with the administration of morphine to warm-blooded animals. The useful compounds are represented by the formula:

wherein R is allyl or a related radical such as chloroallyl, cyclopropyl-methyl or propargyl, and X is the anion of an acid, especially a chloride, bromide, iodide or methylsulfate anion.

The compounds are synthesized as described in United 5tates Patent No. 4,176,I86. A particularly preferred noroxymorphone derivative is methylnaltrexone, but other compounds represented by the above formula are also suitable.

1 enterally or parenterally. However, a preferred method of administration is by injection. Nausea and emesis may follow after even a single does sf morphine, unlikP
intestinal immobility which is usually the effect of chronic repeated usage of the drug. Consequently, it is contemplated that-the patient will be given an injection of methylnaltrexone prior to surgery or other occasion when morphine is used to treat acute pain.
As illustrated :-by :~he ~ifollowing Controls and Examples, our studies show that methylnaltrexone inhibits emesis when administered either together with the morphine or before the morphine is administered. It is thought that methylnaltrexone- or other quaternary noroxymorphone derivatives may be administered up to two hours before the administration of morphine, but that period may be variable. In our studies, methylnaltrexone was administered intramuscularly by means of a syringé. Methylnaltrexone may also be administered enteraIly or parenterally by other means.
It has been found to be effective in dosages in the range of about 0.05 mg/kg to about 1.0 mg~kg for each 1 mg/kg of administered morphine. It was found effective when administered in the same syringe as morphine and also when administered up to about one hour before the administration of morphine.
The effect of methylnaltrexone in reversing the emetic effects of morphine is illustrated herein. The unit of mg/kg refers to milligrams of substance administered per kilograms of body weight.
. ~ CONTROL 1 AND EXAMPLE_1 one mg/kg of morphine was administered intramuscularly to five dogs. Four dogs vomited. In each instance, vomiting occurred within four minutes.
On a different day the same dose of morphine was ~3~5~
1 administered intramuscularly to the same five dogs in the same syringe with 1 mg/kg of methylnaltrexone. None of the dogs vomited.
Six dogs were given intramuscular doses of 1 mg/kg of morphine. All six dogs vomited. On an ~dditional day the same dose of morphine was combined with 0.5 mg/kg of methylnaltraxone and administered in the same syringe to the same dogs. None of the dogs vomited.
one mg/kg of morphine was administered intramuscularly to three dogs. All three dogs vomited.
On an additional day the morphine was combined with 0.25 mg/kg of methylnaltrexone and administered in the same syringe. None of the dogs vomited.
Methylnaltrexone was administered to two dogs prior to the administration of 1 mg/kg morphine. In one dog, 0.5 mg/kg of methylnaltrexone was administered intramuscularly 15 minutes before the morphine. No vomiting occurred. In the second dog, the same dose o~
methylnal~rexone was administered 30 minutes before the administration of morphine. No vomiting occurred.
O. 05 mg/kg methylnaltrexone was administered intravenously to four dogs one minute prior to the administration of 1.0 mg/kg morphine. No vomiting occurred in any of the dogs. On a different day, the same animals were given 1.0 mg/kg morphine without the administration of methylnaltrexone. All four dogs 3 5 vomited .
~3~6t~
The administration of methylnaltrexone alone was found to produce no noticeable effec-ts in the animals. Previous studies with larger doses of methylnaltrexone have demonstrated that unlike the non-quaternary naltrexone, methylnaltrexone does no-t precipitate withdrawal systems in morphine-tolerant dogs. Russell et al., Eur~ J. Pharmacol.
78:255-261 ~19823. Methylnaltrexone has not been found -to interfere with the analgesic activity of morphine or narcotics.
