Isoprenaline and dobutamine are examples of which category of catecholamines?

• A. Endogenous
• B. Synthetic
• C. Semi-Synthetic
• D. Natural

Answer: (B)

These drugs are classified by their origin and how they’re produced. Isoprenaline (isoproterenol) and dobutamine are not produced by the body or found naturally in nature; they’re chemically manufactured as medicines to act on adrenergic receptors. That makes them synthetic catecholamines. They’re designed lab-made derivatives that mimic natural catecholamines but aren’t directly derived from a natural product in the body, so they aren’t endogenous or natural compounds. They aren’t considered semi-synthetic, since semi-synthetic typically means a natural product that’s chemically modified, whereas these drugs are primarily created as new synthetic agents. So the correct category is synthetic.
