Which baclofen administration routes are mentioned in the material?

• A. Oral and Intrathecal
• B. Intravenous and Subcutaneous
• C. Oral and Intramuscular
• D. Inhaled and Topical

Answer: (A)

Baclofen is discussed as being given orally for systemic effect and intrathecally for targeted relief in the spinal fluid. The material mentions these two routes, with intrathecal administration typically via an implanted pump for severe, refractory spasticity. Other routes such as intravenous, subcutaneous, intramuscular, inhaled, or topical are not described for baclofen in this context. So the mentioned routes are oral and intrathecal.
