Study Notes
Morphine DTP
- Morphine is a narcotic analgesic that acts on the central nervous system by binding with opioid receptors.
Pharmacology of Morphine
- Morphine alters pain perception and emotional response to pain, causing respiratory depression, vasodilation, and slows AV node conduction.
- Metabolized by the liver, kidney, and lungs.
Indications for Use of Morphine
- Significant pain
- Sedation
- Autonomic dysreflexia (with systolic BP > 160 mmHg)
Contraindications for Use of Morphine
- Allergy to morphine and/or adverse drug reaction to morphine
- Kidney disease (renal failure)
Precautions for Use of Morphine
- Hypotension
- Respiratory tract burns
- Respiratory depression and/or failure
- Known narcotics addiction
- Concurrent MAOI therapy (antidepressants)
- Cardiac chest pain
Side Effects of Morphine
- Bradycardia
- Drowsiness
- Hypotension
