Useful:

• Description: Apremilast (Otezla) was approved by the FDA on March 21, 2014 for the treatment of adult patients with active psoriatic arthritis. Apremilast is a member of a new class of oral small molecule inhibitors of the phosphosphodiesterase 4 (PDE4) enzyme. When PDE4 is inhibited in immune cells, it results in elevation of intracellular cyclic adenosine monophosphate (cAMP) levels, which can regulate inflammatory mediators. The current clinical data indicate that apremilast is an effective and well tolerated option for the management of psoriasis and PsA in adults. Apremilast is the first and only oral phosphodiesterase IV (PDE- 4) inhibitor and anti-tumor necrosis factor alpha (TNFa) agent launched in the USA by Celgene for the treatment of active psoriatic arthritis (PsA). Apremilast was also approved for the treatment of moderate to severe plaque psoriasis in the USA. Later, this drug was also approved in the European Union (EU) for both indications. Although multiple approaches to the synthesis of apremilast have been described, the most likely process scale approach involves the construction of the challenging stereogenic benzylic carbon center by catalytic asymmetric hydrogenation.
• Uses: Treating active psoriatic arthritis. It is also used to treat moderate to severe plaque psoriasis in certain patients. Apremilast is an oral phosphodiesterase 4 inhibitor used in the treatment of adults with active psoriatic arthritis and adults with moderate to severe plaque psoriasis.
• Clinical Use: Treatment of active psoriatic arthritis (PsA) and moderate to severe chronic plaque psoriasis (PSOR)
• Drug interactions: Potentially hazardous interactions with other drugs Antibacterials: concentration reduced by rifampicin - avoid. Antidepressants: concentration possibly reduced by St John’s wort - avoid. Antiepileptics: concentration possibly reduced by carbamazepine, fosphenytoin, phenobarbital, phenytoin and primidone - avoid.
