This approach is based on the understanding that patients may respond differently to specific medications, even those with similar mechanisms of action. Some individuals may have a partial response to one medication but can achieve better symptom relief with a different agent in the same class. This strategy allows for continuity in treatment while exploring the variations within that pharmacological category.

It's essential to evaluate factors such as the patient's tolerance, any side effects experienced, and their overall treatment history before making this switch. The decision to change medications should also consider the patient's unique response patterns and any comorbid conditions.
