Tricyclic, anti-depressant drugs were developed from the observation that some tricyclic, anti-psychotic drugs elevated a patient’s mood.
Identify the structural features of a tricyclic drug that were found to affect its action as a pure anti-depressant or a mixed anti-psychotic/anti-depressant agent and comment on the structural modifications that can be made to such an anti-depressant drug whilst retaining the essential pharmacophore.
Stalevo 150 contains a combination of levodopa, carbidopa, and entacapone. The ratios of these medications in this combination (all in mg) is 37.5:150:200 (levodopa: carbidopa: entacapone). What is the strength of levodopa in this formulation?
The order is for 1 grain BID and the medication is available as 20 mg per tablet. How many tablets should be administered per dose?

- Enalapril is an anti-hypertension “pro-drug” (i.e., a drug precursor) that isinactive until the ethyl ester (arrow in figure) is hydrolyzed by esterases present in blood plasma. The active drug is the dicarboxylic acid (“enalaprilat”) that results from this hydrolysis reaction.(a) Enalapril is administered in pill form, but enalaprilat must be administered intravenously. Why do you suppose enalapril works as a pill but enalaprilat does not? (b) Enalaprilat is a competitive inhibitor of the angiotensin-convertingenzyme (ACE), which cleaves the blood-pressure regulating peptideangiotensin I. ACE has a KM = 52 μM for angiotensin I, which is presentin plasma at a concentration of 75 μM. When enalaprilat is presentat 2.4 nM, the activity of ACE in plasma is 10% of its uninhibitedactivity.
