1. Morphine: Opioid agonist: binds to the opioid mu-1 and mu-2 and kappa
receptors in the CNS and alters pain perception and response
Side effects: confusion, sedation, constipation, hypotension, respiratory depression
Antidote= naloxene
2. • Demerol: Opioid agonist mu-1 and mu-2 and kappa receptors.
side effects:
-Nausea
- Vomiting
, - Euphoria
- Dysphoria
- Respiratory Depression
Adverse effect: seizures
Antidote= naloxene
3. • Ativan
• : Potentiates action of GABA, resulting in increased neuronal inhibition and CNS
depression,
Side effects:
CNS: dizziness, drowsiness, lethargy, hangover, headache, ataxia, slurred speech,
forgetfulness, confusion, mental depression,
4. Dilantin: 1. Anticonvulsant: stabilizes neuronal membranes and limits seizure
activity by either increasing efflux or decreasing influx of sodium ions across cell
membranes in the motor cortex during generation of nerve impulses.
2. Antiarrhythmic: normalizes sodium influx to Purkinje's fibers in patients with
induced dysrhythmias.
Side effects:
1. nausea, vomiting
2. CNS depression
3. respiratory depression
4. heart blocks
5. hypotension
6. dysrhythmias
5. • Nitroglycerine: -Reduces venous tone. (Blood pooling in periph veins, decreas-
ing venous return to the heart.
-Decreased periph. vascular resistance.
