- Brief Summary
The curcumin exhibits poor bioavailability is well documented. The major reasons attributed to the low bioavailability of curcumin are poor absorption, rapid metabolism, and rapid systemic elimination. In humans a comprehensive pharmacokinetic data do not exist. The pilot studies summarized that low systemic bioavailability is observed in humans following oral dosing. First phase I clinical trial of curcumin was done in 25 patients with high-risk or pre-malignant lesions. The starting dose was 500 mg/day and if no toxicity was noted, the dose was then escalated to another level in the order of 1,000, 2,000, 4,000, 8,000, and 12,000 mg/day. There was no treatment-related toxicity up to 8 g/day but the bulky volume of the drug was unacceptable to the patients beyond 8 g/day. The serum concentration of curcumin usually peaked at 1 to 2 hours after oral intake of curcumin and gradually declined within 12 hours. The average peak serum concentrations after taking 4,000 mg, 6,000 mg and 8,000 mg of curcumin were 0.51 +/− 0.11 μM, 0.63 +/− 0.06 μM and 1.77 +/− 1.87 μM, respectively. Urinary excretion of curcumin was undetectable. Lao et al conducted a pilot study in 24 healthy subjects and they administered curcumin up to 12g/day. They detected curcumin in the serum samples of only those who took 10 and 12g/day. It was reported that a daily oral dose of 3.6g of curcumin results in detectable levels in colorectal tissue, which might be sufficient to exert pharmacological activity. Curcumin undergoes metabolism in the liver particularly via glucuronidation and sulfation. The metabolites of curcumin such as glucoronides appear to lack any pharmacological activity.The systemic elimination of curcumin is another contributing factor for low bioavailability of curcumin. The initial reports by Wahl storm and Blennow showed that after oral administration of 1g/kg curcumin to rats, more than 75% of curcumin was excreted in feces and negligible amount was detected in urineIncrease the bioavailability of curcumin, is also being explored. The roles of adjuvant, which can block the metabolism of curcumin, are of great interest. Combining curcumin with Piperine has been shown to increase the bioavailability in rats and in human subjects. Piperine is an inhibitor of glucuronidation of curcumin. The study conducted by Shobha et al demonstrated that concomitant administration of curcumin with Piperine produced 150% increase in bioavailability in rats and 2000% increase in man. Other ways to improve the bioavailability of curcumin is by making curcumin nanoparticles micelles and phospholipid complexes.The possible advantages attributed to such formulations are (a) Provide longer circulation (b) Increase the cellular permeability and (c) Induce resistance to metabolic processes.Systemic elimination or clearance of curcumin from the body is an important factor determining its biological activity. Wahlstorm and Blennow reported that, when 1 g/kg curcumin was given orally to rats, 75% was excreted in the feces and negligible amounts were found in the urine. A clinical study of 15 patients receiving oral curcumin in doses between 36 and 180 mg daily for up to 4 months found neither curcumin nor its metabolites in urine, but the drug was recovered from feces. The absorption and elimination half-life of orally administered curcumin (2 g/kg) in rats were reported to be 0.31 0.07 and 1.7 0.5 h, respectively. However, the same dose of curcumin in humans did not allow the calculation of these half-life values because serum curcumin levels were below detection limits at the majority of time points in most of the experimental patients. Existing evidence in the literature is insufficient to draw conclusions about the factors controlling the in vivo elimination half-life of curcumin, and future studies are warranted to address this issue [7].
