In pharmacology and biochemistry, mode of action (MoA) describes a functional or anatomical change, resulting from the exposure of a living organism to a substance. [1] In comparison, a mechanism of action (MOA) describes such changes at the molecular level.
In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. [2] A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor . [ 3 ]

Tyramine is broken down by MAO-A and MAO-B, therefore inhibiting this action may result in its excessive build-up, so diet must be monitored for tyramine intake. MAO-B inhibition reduces the breakdown mainly of dopamine and phenethylamine , so there are no associated dietary restrictions.
The primary mechanism of phentermine's action in treating obesity is the reduction of hunger perception, which is a cognitive process mediated primarily through several nuclei within the hypothalamus (in particular, the lateral hypothalamic nucleus, arcuate nucleus, and ventromedial nucleus).
The long side-chain (R 2 in the diagram) determines the chemical properties, the mode of action and the strength of bisphosphonate drugs. The short side-chain (R 1), often called the 'hook', mainly influences chemical properties and pharmacokinetics. See nitrogenous and non-nitrogenous sections in Mechanism of action below.
Methylphenidate's mechanism of action in the release of dopamine and norepinephrine is fundamentally different from most other phenethylamine derivatives, as methylphenidate is thought to increase neuronal firing rate, [125] [126] [127] whereas amphetamine reduces firing rate, but causes monoamine release by reversing the flow of the monoamines ...
Denosumab inhibits this maturation of osteoclasts by binding to and inhibiting RANKL. Denosumab mimics the natural action of osteoprotegerin, an endogenous RANKL inhibitor, that presents with decreasing concentrations (and perhaps decreased effectiveness) in people with osteoporosis. This protects bone from degradation, and helps to counter the ...
