Mechanism of action
Individually, bupropion and naltrexone each target pathways in the central nervous system that influence appetite and energy use.
- Bupropion is a reuptake inhibitor and releasing agent of both norepinephrine and dopamine, and a nicotinic acetylcholine receptor antagonist, and it activates proopiomelanocortin (POMC) neurons in the hypothalamus which give an effect downstream, resulting in loss of appetite and increased energy output. The POMC is regulated by endogenous opioids via opioid-mediated negative feedback.
- Naltrexone by contrast is a pure opioid antagonist, therefore further augmenting bupropion’s activation of the POMC.
Combined, bupropion/naltrexone has an effect on the reward pathway that results in reduced food craving. In 2009, Monash University physiologist Michael Cowley was awarded one of Australia’s top research honors, the Commonwealth Science Minister’s Prize for Life Scientist of the Year, in recognition of his elucidation of these pathways, which led to the development of the combination medication.
History Of Contrave pills for sale
Orexigen submitted a New Drug Application (NDA) for this drug combination to the FDA On 31 March 2010.Having paid a fee under the Prescription Drug User Fee Act, Orexigen was given a deadline for the FDA to approve or reject the drug of 31 January 2011. On 7 December 2010, an FDA Advisory Committee voted 13-7 for the approval of Contrave, and voted 11-8 for the conduct of a post-marketing cardiovascular outcomes study. Subsequently, on 2 February 2011, the FDA rejected the drug and it was decided that an extremely large-scale study of the long-term cardiovascular effects of Contrave would be needed, before approval could be considered. It was ultimately approved in the United States in the fall of 2014
In December 2014, the EU’s Committee for Medicinal Products for Human Use (CHMP) endorsed the combination for licensure as an obesity medication when used alongside diet and exercise. Approval was granted in late March 2015.
In May 2015, Orexigen ended a safety study of its diet drug earlier than planned, because an independent panel of experts says the drug maker “inappropriately” compromised the trial by prematurely releasing interim data. The early data release reported a reduction in heart attacks that was no longer observed when a more complete view of the data was analyzed. contrave pills for sale in Ca
