which drug causes release of dopamine from the storage sites at the end of nerve cells that are still intact
Blocks the reuptake of dopamine into the nerve endings, allowing more to accumulate both centrally and peripherally
Does not stimulate dopamine receptors directly
amantadine (Symmetrel)
Blue Box info
Amantadine (Symmetrel) is believed to work in the CNS by eliciting the release of dopamine from nerve endings, resulting in higher concentrations of dopamine in the CNS. It is most effective in the earlier stages of PD when there are still significant numbers of nerves to act on and dopamine to be released. As the disease progresses, however, the population of functioning nerves diminishes, and so does amantadine’s effect. Amantadine is usually effective for only 6 to 12 months. After amantadine fails to relieve the hypokinesia and rigidity, a dopamine agon- ist such as bromocriptine is usually tried next. Amantadine is contraindicated in patients who have shown a hypersensitivity reaction to it, women who are lactating, and children younger than 1 year of age (amantadine is also an antiviral drug).

NOT WANTING TO BURN OUT RECEPTORS
WHAT ARE THE EXPECTED THERAPEUTIC RESPONSES TO LEVODOPA?
Levodopa is converted to dopamine and helps supplement the deficient amounts of dopamine in the brain. In PD, there is an imbalance between dopamine and Ach. Levodopa helps restore this balance. Improvement in activities of daily living and other symptoms of the disease is the result.
What is the concept of half life?
is the time it takes for one half of a given amount of a drug in the body to be removed and is a measure of the rate at which the drug is eliminated from the body. For instance, if the maximum level that a particular dosage could achieve in the body is 100 mg/L and in 8 hours the measured drug level is 50 mg/L, then the estimated half- life for that drug is 8 hours.

Because it has clinically significant grapefruit juice–drug interactions
What is the concept of first-pass effect?
If the drug is metabolized in the liver or excreted in the bile, some of the active drug will be inactivated or diverted before it can reach the general circulation and its intended sites of action.
