Dosing medication for children is complex due to physiological changes; for instance, body fat can increase from just 1-2% in a preterm neonate to 20-25% in a 1-year-old. This variability is why various methods, including the historical query of **What is Dilling's formula?**, were developed.

Over 75% of pediatric prescriptions in North America and Europe have historically been considered "off-label" due to the scarcity of pediatric-specific research. A common and straightforward tool used to estimate a child's medication dosage from an adult dose is **Clark's rule**, which bases the calculation on the child's weight. This practice helps in the process of preventing potentially dangerous dosing errors in children, whose bodies process drugs differently than adults.

While historically significant, formulas like Fried's rule are now considered outdated for clinical use. This calculation method was once a straightforward way to estimate an infant’s medication dose based on their age in months and the standard adult dose.

Accurate medication dosing in children is critical for preventing potentially fatal errors and ensuring therapeutic efficacy. Understanding what is the Clark's rule provides valuable insight into the historical methods of pediatric pharmacology and highlights the evolution toward safer, more precise standards.
