Why are companies challenging this patent?

Roche Holding AG, the original patent holder, has been under pressure from generic manufacturers to extend the life of the patent [2]. This has led to patent battles and legal challenges, delaying the entry of cheaper generic alternatives.

How does this delay affect patients?

Patients may have to continue paying higher prices for the branded medication until the patent expires, potentially limiting access to treatment, especially for those with limited financial resources [3].

What alternatives are available for patients?

While waiting for the patent to expire, patients may consider alternative treatments for their condition. This could include different benzodiazepines or other classes of medications, such as non-benzodiazepines or anticonvulsants [4].
