Onset of action appears faster than some selective serotonin reuptake inhibitors (SSRI) and similar to tricyclic antidepressants.In 2010, NICE recommended generic SSRIs as first line choices, as they are "equally effective as other antidepressants and have a favourable risk–benefit ratio." With respect to mirtazapine, it found: "There is no difference between mirtazapine and other antidepressants on any efficacy measure, although in terms of achieving remission mirtazapine appears to have a statistical though not clinical advantage. In addition, mirtazapine has a statistical advantage over selective serotonin reuptake inhibitors in terms of reducing symptoms of depression, but the difference is not clinically significant. However, there is strong evidence that patients taking mirtazapine are less likely to leave treatment early because of side effects, although this is not the case for patients reporting side effects or leaving treatment early for any reason. "A 2011 Cochrane review that compared mirtazapine to other antidepressants found that, while it appears to have a faster onset in people for whom it works (measured at two weeks), its efficacy is about the same as other antidepressants after six weeks use.A 2012 review focused on antidepressants and sleep found that in many people with sleep disorders caused by depression, mirtazapine reduces the time it takes to fall asleep and increases the quality of sleep, but that in some people it can disturb sleep, especially at higher doses, causing restless leg syndrome in 8 to 28% of people and in rare cases causes REM sleep behavior disorder.
Vorinostat (rINN) also known as Suberoylanilide hydroxamic acid  (suberoyl+anilide+hydroxamic acid abbreviated as SAHA) is a member of a larger class of compounds that inhibit histone deacetylases (HDAC). Histone deacetylase inhibitors (HDI) have a broad spectrum of epigenetic activities. Vorinostat is marketed under the name Zolinza ( zoh-LIN-zə) by Merck for the treatment of cutaneous manifestations in patients with cutaneous T cell lymphoma (CTCL) when the disease persists, gets worse, or comes back during or after two systemic therapies. The compound was developed by Columbia University chemist Ronald Breslow and Memorial Sloan-Kettering researcher Paul Marks

Medical uses
Vorinostat was the first histone deacetylase inhibitor approved by the U.S. Food and Drug Administration (FDA) for the treatment of CTCL on October 6, 2006. It also failed to demonstrate efficacy in treating acute myeloid leukemia in a phase II study. Mechanism of action
Vorinostat has been shown to bind to the active site of histone deacetylases and act as a chelator for zinc ions also found in the active site of histone deacetylases. Vorinostats inhibition of histone deacetylases results in the accumulation of acetylated histones and acetylated proteins, including transcription factors crucial for the expression of genes needed to induce cell differentiation. It acts on class I, II and IV of histone deacetylase. Clinical trials
Vorinostat has also been used to treat Sézary syndrome, another type of lymphoma closely related to CTCL.A recent study suggested that vorinostat also possesses some activity against recurrent glioblastoma multiforme, resulting in a median overall survival of 5.7 months (compared to 4–4.4 months in earlier studies).
