The Effect of Thickened Water on Ciprofloxacin Pharmacokinetics: A Comparative Study in Adult Males.

Background/

Objectives

The use of food thickeners with ciprofloxacin tablets may result in a gelatinous appearance and experience delayed dissolution, which presents a challenge for the drug's efficacy, creating a healthcare economic issue. However, the pharmacokinetic impact of this compound in humans remains uncertain. Therefore, a comparative pharmacokinetic study of ciprofloxacin was conducted on healthy adult Japanese males.

Methods

We compared the effects of administering tablets with water or thickened water and crushed tablets mixed with thickened water. The maximum blood concentration (Cmax) of ciprofloxacin determines the drug's efficacy.

Results

There were variations in drug absorption across different administration methods. The group who took the tablets immersed in thickened water exhibited different results in the area under the blood drug concentration-time curve (AUC) and Cmax compared to the group who took the tablets in regular water. Notably, the group that consumed the crushed tablets mixed with thickened water demonstrated equivalent results for both AUC and Cmax.

Conclusions

Administering crushed tablets in thickened water may yield pharmacokinetics comparable to those of tablets taken with water. However, the process of crushing tablets may result in the loss of active ingredients and compromise the formulation, necessitating a comprehensive assessment before administration.
