When rifampicin is taken with a meal, its peak blood concentration falls by 36%. Antacids do not affect its absorption. [ 57 ] The decrease in rifampicin absorption with food is sometimes enough to noticeably affect urine color, which can be used as a marker for whether or not a dose of the drug has been effectively absorbed.

Two mechanisms have been proposed as the primary pathway of hydroxylation in P450 enzymes. Two of the most commonly proposed mechanisms used for the hydroxylation of an sp 3 C–H bond The first pathway suggested is a cage-controlled radical method ("oxygen rebound"), and the second involves a concerted mechanism that does not utilize a radical ...
In some literature articles, the terms "mechanism of action" and "mode of action" are used interchangeably, typically referring to the way in which the drug interacts and produces a medical effect. However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living ...
The risk of bleeding is increased if used at the same time as other blood thinning drugs such as nonsteroidal anti-inflammatory drugs, antiplatelet drugs and heparin. [2] The blood thinning effects can be reduced if used at the same time as rifampicin and phenytoin, and increased with fluconazole.
