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 ettects: confusion, sedation, constipation, hypotension, respiratory depression Antidote=
naloxene
2. • Demerol: Opioid agonist mu-1 and mu-2 and kappa receptors.
side ettects:
-Nausea
- Vomiting
- Euphoria
- Dysphoria
- Respiratory Depression
Adverse ettect: seizures
Antidote= naloxene
3. • Ativan
• : Potentiates action of GABA, resulting in increased neuronal inhibition and CNS depression, Side
ettects:

, 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
ettects:
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, decreasing venous return to the
heart.
-Decreased periph. vascular resistance.
-Dilation of coronary arteries and relief of coronary artery spasm.
