As obesity is being regarded as a particular medical problem rather than just a result of overeating, pharmaceutical companies are actively involved in the manufacturing of anti-obesity drugs to control the ailment.
Side effects such as the risk of psychiatric disorder, stroke is expected to impact the market growth over the forecast period negatively. Numerous anti-obesity drugs approved in the past decade such as Knoll and Acomplia (rimonabant) have been removed due to side effects such as suicidal thoughts, depression and cardiovascular problems associated with their long-term usage. Owning to the factors as mentioned earlier, healthcare professionals have a negative perception of the anti-obesity drugs and do not advise them to consumers.

The transition of medicinal products from phase one to market is tough as more than 80% of the drugs get terminated before reaching pre-registration.

Limited efficiency of currently available drugs and the unfavorable opinion of healthcare professionals and patients of anti-obesity drugs due to side effects and withdrawal following adverse post-marketing safety studies are hindrances to the market.
