Dopamine belongs to the family of catecholamines. It is a neurotransmitter. • Hormones, Epinephrine and Norepinephrine (other catecholamines) are derived from Dopamine • Dopamine plays a significant role in learning, goal-directed behavior, regulation of hormones, motor control. DOPAMINE SYNTHESIS Phenylalanine (amino acid from diet) -> phenyalanine hydroxylase -> Tyrosine -> Tyrosine hydroxylase -> DOPA -> Dopa decarboxylase -> Dopamine KEY POINT: Dopamine is synthe...

Explain the agonist-to-antagonist spectrum of action of psychopharmacologic agents. To understand the agonist-to-antagonist spectrum of action of psychopharmacologic agents, it is first important to understand what does the terms agonist and antagonist means. An agonist refers to a chemical that binds to a receptor, the receptor activates and a biological response is produced. In comparison, an antagonist blocks the action of agonist, and an inverse agonist causes an action opposite to t...

half life Half-life (t½) is an important pharmacokinetic measurement. The metabolic half-life of a drug in vivo is the time taken for its concentration in plasma to decline to half its original level. Half-life refers to the duration of action of a drug and depends upon how quickly the drug is eliminated from the plasma. The clearance and distribution of a drug from the plasma are therefore important parameters for the determination of its half-life. B max The maximum amount of drug or radio...
