Development of tolerance to antinociceptive effects of an intrathecal morphine/clonidine combination in rats
TLDR
Tolerance developed to the antinociceptive effects of the drug combination, but at a slower rate than to morphine alone, and no evidence of toxicity or injury to the spinal cord was observed.
Pharmacological Characterization of Noroxymorphone as a New Opioid for Spinal Analgesia
TLDR
The results of this study indicate that noroxymorphone is a potent &mgr;-opioid receptor agonist when administered intrathecally, and is an interesting opioid for spinal analgesia with a low potential for abuse.
Antinociceptive effect of intrathecal loperamide: role of mu-opioid receptor and calcium channels.
Antinociceptive effects and central nervous system depression caused by oxycodone and morphine in rats.
TLDR
Antinociception and central nervous system depression was more profound with oxycodone than with morphine after intraperitoneal and subcutaneous administration, but was not observed after intratechal administration of either drug.
ctivation of delta-opioid receptor contributes to the antinociceptive ffect of oxycodone in mice
TLDR
This study examined whether delta-opioid receptor was involved in oxycodone antinociceptive effect in male mu-opIOid receptor knock-out mice, and found that delta-operative receptor antagonists completely blocked the supraspinal ant inociception effect of oxy codone in MOR-KO mice.
Pharmacodynamics of Orally Administered Sustained- release Hydromorphone in Humans
TLDR
A single oral dose of a new sustained-release formulation of hydromorphone provided analgesia to experimental pain beyond 24 h of its administration, and a statistically significant linear relation between the hydrom orphone plasma concentration and the analgesic effect on painful stimuli existed.
Neuroaxial hydromorphone for control of postsurgical, obstetric, and chronic pain
TLDR
Hydromorphone is associated with dose-dependent reductions in respiratory rate and minute ventilation, however, it is less sedating than morphine 7'9 and less likely to release histamine.

Studies of the Pharmacology and Pathology of Intrathecally Administered 4‐Anilinopiperidine Analogues and Morphine in the Rat and Cat
TLDR
The results suggest that sufentanil, alfent anil, and fentanyl exert their analgesic effects in vivo at a spinal cord site that has properties comparable to those of the site acted upon by morphine.
Pharmacokinetics of Intrathecal Morphine and Meperidine in Humans
TLDR
Large inter-individual differences in morphine and meperidine CSF kinetics existed, and some of the reported individual differences in duration of effects may be explained by the differences in lipid solubilities of the drugs.
Epidural and intrathecal opiates: Cerebrospinal fluid and plasma profiles in patients with chronic cancer pain
TLDR
It is concluded that analgesia induced by intrathecal or epidural morphine injections is caused by drug acting at both spinal and supraspinal sites, and the use of spinal opiates such as morphine is of limited value in patients whose pain is not adequately managed by high systemic doses of morphine‐like drugs.
