==Mechanism of Action==

==Fluoxetine==

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) which functions by inhibiting the reuptake of serotonin in the pre-synaptic neuron. This inhibition of uptake of reuptake of 5-HT_1A into pre-synaptic neurons is highly selective and does not affect noradrenaline, dopamine, acetylcholine, histaminic or alpha-1 adrenergic receptors. 5-HT_1A receptors have an effect on mood and behaviour. SSRIs are derived from TCAs, such as [[Clomipramine]]. SSRIs act to bring about changes in conformation of receptors, this can take 3-5 weeks<ref>Overall, K.L., 2004. Paradigms for pharmacologic use as a treatment component in feline behavioural medicine. Journal of Feline Medicine and Surgery 6, 29–42</ref>. Regulation of second messengers (cAMP, Ca²⁺, cGMP, IP₃) is responsible for the major effect. Their actions on protein kinases then act to change neuronal metabolism and receptor protein transcription<ref>Overall, K.L., 2001.

Due to the long half-life of fluoxetine it is not necessary to gradually reduce or taper the dose. Once treatment with fluoxetine has ceased continued behavioural modification is advisable to avoid the reappearance of clinical signs. The long half-life of fluoxetine and its metabolites also mean that a period of at least 6 weeks should be allowed to pass before administration of any drugs which may interact adversely.
