Literature growth in pharmacokinetics

Area of Science:

• Bibliometrics
• Pharmacokinetics
• Scientific Literature Analysis

Background:

• Analysis of scientific literature growth is crucial for understanding research trends.
• Pharmacokinetics and bioavailability literature experienced significant expansion.
• Comparison with general chemical literature growth provides context.

Purpose of the Study:

• To analyze the growth patterns of pharmacokinetic and bioavailability literature from 1964 to 1980.
• To compare the growth rate of pharmacokinetic literature with that of the broader chemical literature.
• To assess the predictability of future literature trends using mathematical models.

Main Methods:

• Literature growth analysis using time-series data.
• Exponential growth modeling and half-life calculations.
• Comparative analysis of growth rates between specific and general scientific fields.

Main Results:

• Pharmacokinetic literature doubled approximately every 1.6 years between 1964 and 1980.
• A significant slowdown or stagnation in pharmacokinetic literature growth was observed from 1978 to 1980.
• Pharmacokinetic literature growth outpaced that of the total chemical literature during the study period.
• The half-life of chemical literature growth increased from 8.28 years (1950-1967) to 12.4 years (1968-1980).

Conclusions:

• Mathematical models can describe past literature trends but are limited in predicting future research trajectories in specialized fields like pharmacokinetics.
• External factors (psychological, sociological, political, economic) may influence literature growth dynamics.
• The rapid, yet potentially fluctuating, growth of specialized scientific fields requires nuanced analytical approaches beyond simple mathematical extrapolation.
