Analyzing Antibacterial Drugs Floating Times for Efficiency Evaluation: A Review

Objective: To investigate the significance of floating lag time (FLT) and total floating time (TFT) in gastro retentive drug delivery systems (GRDDS), focusing on their implications for drugs requiring sustained release or targeted delivery within the gastrointestinal tract. Methods: A review was conducted to analyze the floating characteristics of drug delivery systems, particularly emphasizing FLT and TFT. Metronidazole was selected as a case study due to its relevance in antibacterial therapy and its known properties in GRDDS. Results: Metronidazole demonstrates superior floating characteristics, with a TFT exceeding 24 hours and a minimal FLT of only 2 seconds. This prolonged floating duration makes it highly suitable for controlled and sustained release formulations, particularly in applications requiring targeted delivery to the stomach. Conclusion: Among antibacterial agents, Metronidazole emerges as an optimal candidate for GRDDS, offering potential enhancements in therapeutic efficacy and patient compliance through sustained release mechanisms.
