Why was tenuate dospan discontinued?

Why was Tenuate Dospan discontinued in the US market?

[1] Tenuate Dospan, a popular diet tablet, was discontinued in the US due to its high risk of side effects, especially liver damage and respiratory problems.

What led to its market removal?

Tenuate Dospan contained diethylpropion, an anorectic agent, which was linked to severe liver damage and increased risk of respiratory and cardiovascular issues in long-term users. [2] The FDA began receiving reports of adverse events associated with diethylpropion use.

Did regulatory actions play a role?

Yes, regulatory actions were a decisive factor. In 2010, the FDA required pharmaceutical manufacturers to update their labels to include a boxed warning highlighting the increased risk of liver damage, depression, suicidal thoughts, and other mental health issues.

Was the decision influenced by patent expiration?

Yes, the patent expiration of Tenuate Dospan's active ingredient also contributed to its discontinuation. After the patent expired, generic versions of diethylpropion began to flood the market, and the lack of exclusivity led to reduced profitability for the manufacturer.
