These findings suggest that low bioavailability associated with customary doses of silymarin may be overcome with doses above 700 mg three times a day (tid) [33].
Higher than customary doses of silymarin, or formulations with improved bioavailability, might increase the risk of flavonolignan interactions with OATP substrates in patients [38].
In spite of a fairly large amount of studies dedicated to these potential problems, no clinically relevant interactions between silymarin and other drugs have been identified upon administration in the recommended customary doses.
Of note, the MTX dose used in this trial, while consistent with that approved in Japan at the time the trial was planned, was suboptimal (6 8 mg/week) in the context of customary doses elsewhere 18 and as used in the GO-FORWARD study (15 25 mg/week).
To compare the T-oligo effect to that of a recognized anti-breast cancer chemotherapeutic agent, cisplatin [ 44- 48], and to an anti-estrogen frequently used to treat estrogen receptor positive breast cancers [ 49- 51], MCF-7 cells were treated with customary doses of cisplatin (10 μM), the anti-estrogen ICI 182,780 (100 nM) or T-oligo (40 μM) as above.
Using the Hemochron Jr., we consistently noted a higher than customary heparin dose required to achieve an activated clotting time (ACT) that, according to the literature and our quality standards, should be more than 480 seconds.
However, calculation of the maximal unbound portal vein concentrations/IC50 values indicated a low risk for silymarin-drug interactions in hepatic uptake with a customary silymarin dose.
It was when Cole, in last year's press conference, suggested that the title should be an aspiration that Hodgson applied one of his customary cold doses of realism.
It has no known adverse effects in customary, and even substantial, doses [ 11].
When estimating astronaut radiation organ doses and dose equivalents it is customary to use the Computerized Anatomical Man (CAM) model of human geometry to account for body self-shielding.
Nostalgia is one half of the Janus equation, but it's customary to see in the New Year with a dose of apprehension, too.
