Microcomputer-based programs for calculating mean and variance residence time by the method of prospective areas

Area of Science:

• Pharmacokinetics
• Computational Biology
• Software Development

Background:

• Existing microcomputer pharmacokinetic software packages facilitate data analysis.
• Pharmacokinetic analysis often requires multiple calculations with varying assumptions.
• Calculating mean and variance above residence time (MRT and VRT) is crucial for comprehensive pharmacokinetic profiling.

Purpose of the Study:

• To expand a published microcomputer-based pharmacokinetic software package.
• To incorporate programs for calculating mean and variance above residence time (MRT and VRT) using the method of prospective areas.
• To provide integrated software for analyzing plasma concentration-time, urinary excretion, and in-vitro dissolution data.

Main Methods:

• Development of three specialized programs for plasma, urinary, and dissolution data.
• Implementation of the method of prospective areas for MRT and VRT calculations.
• Modular software design for integrated functionality and user-selected analysis depth.

Main Results:

• Successfully expanded pharmacokinetic software with MRT and VRT calculation capabilities.
• Tested programs with original and simulated pharmacokinetic data, confirming accuracy.
• Integrated software package allows extensive data analysis without re-entry.

Conclusions:

• The enhanced software package provides a versatile tool for pharmacokinetic analysis.
• Modular design ensures ease of use, modification, and adaptation to new methods.
• Expanded capabilities support more thorough pharmacokinetic data interpretation.
