Effect of psyllium hydrophilic mucilloid on serum cholesterol in the elderly.

Author information

Department of Pharmacy Practice, University of Florida, Gainesville.


The effect of psyllium hydrophilic mucilloid (PHM) when used as a laxative and/or stool softener on serum cholesterol concentrations was examined in 176 ambulatory elderly participants attending a health screening program. The change in one-year serum cholesterol concentration in subjects using PHM was compared with the change in cholesterol in 741 participants who did not report the use of PHM. Serum cholesterol concentration decreased by 0.073 mmol/liter (2.82 mg/dl) in the treatment group compared with a decrease of 0.036 mmol/liter (1.39 mg/dl) in the control group. After adjusting for confounding factors, excluding psyllium dose, by using a multiple regression model there was no significant difference in the change in serum cholesterol concentration (P = 0.935). PHM dosage information was available for 158 participants. After adjusting for baseline serum cholesterol and confounding factors using multiple regression analysis, it was found that the dose of PHM administered was significantly correlated with the change in serum cholesterol (P = 0.0120). For every 1-g increase in daily PHM dose there was a 0.022 mmol/liter (0.84 mg/dl) decrease in serum cholesterol concentration.
