1) The drug carbidopa enhances the action of the drug levodopa by:
inhibiting the conversion of levodopa to dopamine in the basal ganglia.
inhibiting the conversion of levodopa to dopamine in the periphery.
promoting the conversion of levodopa to dopamine in the basal ganglia.
promoting the conversion of levodopa to dopamine in the periphery.
2) Identify a drug that inhibits the metabolism of dopamine.
Levodopa
Selegiline
Bromocriptine
Amantadine
3) Constipation is a side effect of opioid use caused by the:
spasmogenic activity of opioids on smooth muscle and mu2 receptors in the gastrointestinal (GI) tract.
spasmolytic activity on smooth muscle and mu2 receptors in the GI tract.
spasmogenic activity on smooth muscle and mu1 receptors in the GI tract.
spasmolytic activity on smooth muscle and mu1 receptors in the GI tract.
1. inhibiting the conversion of levodopa to dopamine in the periphery. Thus it prevents side effects of nausea and vomiting by levodopa
2. Seligiline works by inhibiting the metabolism of dopamine
3. spasmogenic activity of opioids on smooth muscle and mu2receptors in the gastrointestinal (GI) tract. It results in constipation

1. Which action by a skeletal muscle relaxant is the major mechanism of action? Reducing motor nerve impulse transmission to the skeletal muscles. Inhibiting glucose uptake in skeletal muscles. Binding to opioid and serotonin receptors in the brain to induce sleep. Dilating blood vessels in skeletal muscles and reducing the need for contraction. 2. In what way do uric acid synthesis inhibitors reduce gout symptoms? Group of answer choices Increasing the amount of enzymes that enhance urinary excretion of uric...
