Comparison of Oral Morphine Versus Nasal Ketamine Spray With Chitosan in Cancer Pain Outpatients

2015-10-29 14:53:23 | BioPortfolio


34 adult (>18 years) cancer pain outpatients with Opioid base therapy because of pain and breakthrough pain or extreme pain on movement will be included in this prospective, randomized, double-blind crossover study.

Over a period of 3 weeks patients will go through 3 treatment arms, each one lasting one week: Group A receives morphine drops and Placebo spray, Group B receives ketamine/chitosan spray nasal and Placebo drops and Group C receives morphine drops and ketamine/chitosan spray nasal.

Primary endpoint is time to onset of action of intranasal ketamine compared with morphine drops. Secondary endpoint is the median numeric rating scale (NRS) improvement after using the spray or morphine or the combination of ketamine spray and morphine drops.

Inhaled Morphine Compared With Morphine By Mouth in Treating Cancer Patients With Breakthrough Pain

RATIONALE: Morphine that is inhaled may be more rapidly absorbed than morphine that is given by mouth. It is not yet known if inhaled morphine is more effective than morphine given by mout...

Pain Medicine for Wound Care Procedures

This is a randomized double-blind study to determine if the administration of a small-dose of ketamine (an anesthetic)added to morphine (an opioid) contributes to reducing pain intensity d...

Administration of Ketamine to Prevent the Post-Operative Pain

The surgery of breast cancer is responsible for post-operative pain, needing in about 30% some morphine consumption; like that, the association of ketamine with general anaesthesia may dec...

Ketamine Improves Post-Thoracotomy Analgesia

Thoracotomy for lung tumor or for minimally invasive direct coronary artery bypass (MIDCAB) surgery, may be associated with debilitating pain. Ketamine was shown to enhance opioid antinoci...

Association of Intravenous Ketamine With Thoracic Epidural Analgesia: Effects on Pain and Respiratory Function Following Thoracotomy.

Ketamine for chronic non-cancer pain: A meta-analysis and trial sequential analysis of randomized controlled trials.

Ketamine has been suggested to be efficient in relieving chronic pain. However, there is inconsistency across studies investigating the effect of ketamine for chronic pain management. We aimed to perf...

Ketamine in the treatment of acute pain.

Ketamine is an old anesthetic agent that relieves pain by reducing central sensitization in the central nervous system. This is advantageous for patients suffering from severe pain prior to surgery or...

Morphine: double-faced roles in the regulation of tumor development.

Morphine, a highly potent analgesic, is one of the most effective drugs for the treatment of severe pain associated with cancer. It directly acts on the central nervous system to relieve pain, but als...

Use of Ketamine in a Multimodal Analgesia Setting for Rapid Opioid Tapering in a Profoundly Opioid-Tolerant Patient: A Case Report.

Opioids are frequently used for the treatment of chronic pain, and patients taking high doses are at increased risk of complications and adverse opioid-related events. Ketamine is appealing as an opio...

Medical and Biotech [MESH] Definitions

A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.

Acute pain that comes on rapidly despite the use of pain medication.

A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.

An opioid analgesic with actions and uses similar to those of MORPHINE, apart from an absence of cough suppressant activity. It is used in the treatment of moderate to severe pain, including pain in obstetrics. It may also be used as an adjunct to anesthesia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1092)

A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.
