Creatine phosphate is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high-energy phosphates in muscle, skeletal, and brain.

N tau-methylhistamine is one of the histamine metabolites. N tau-methylhistamine in plasma and urine is a good parameter for histamine release and the determination of this histamine metabolite is generally less hampered by possible artifacts (due to basophil disrupture a very short half-life time or bacterial production) than determinations of histamine itself.

Bepotastine free base is a histamine 1 (H1) receptor antagonis.
