The market response includes a wide array of supportive interventions designed specifically to mitigate the spasticity hallmark of Pure HSP, which explains the higher attention and resource allocation this segment receives compared to complicated forms that may present more heterogeneous and complex manifestations with less consistent treatment outcomes.

Hereditary Spastic Paraplegia Market Insights, By Therapeutics – Muscle Relaxants lead due to significant safety and efficacy

Hereditary spastic paraplegia (HSP) is a rare genetic disorder characterized by progressive lower limb spasticity and weakness, with no currently approved cure. As a result, treatment primarily focuses on symptom management, particularly reducing spasticity to improve mobility and quality of life.

Muscle relaxants, such as baclofen, tizanidine, and diazepam, dominate the therapeutics segment with an estimated 41.2% share in 2025. They are the first-line treatment for spasticity, a hallmark symptom of the disease. The lack of disease-modifying therapies further solidifies their role as the mainstay of clinical management. High prescription rates, supported by guidelines from the European Academy of Neurology (EAN), reinforce their widespread use, with many patients also receiving intrathecal baclofen pumps or botulinum toxin injections for severe cases.

A 2023 study in Frontiers in Neurology highlighted that over 70% of HSP patients rely on muscle relaxants, with intrathecal baclofen showing significant efficacy in refractory spasticity. While emerging therapies like gene editing and neuroprotective agents are under investigation, muscle relaxants will likely remain the dominant therapeutic option until targeted treatments become available. Their critical role in symptom control ensures continued market leadership in HSP management.

Hereditary Spastic Paraplegia Market Insights, By Route of Administration – Oral leads due to lack of approved non-oral disease-modifying therapies

The oral route of administration is the most prominent segment and is expected to account for 53.1% share of the global hereditary spastic paraplegia market in 2025 due to its convenience, patient compliance, and widespread use of first-line muscle relaxants like baclofen and tizanidine in pill form. Since HSP is a chronic condition requiring long-term medication, oral drugs are preferred by both clinicians and patients for their ease of use, non-invasiveness, and ability to be self-administered at home.

Unlike invasive methods (e.g., intrathecal baclofen pumps or botulinum toxin injections), oral medications do not require hospital visits or specialized procedures, making them more accessible and cost-effective. Additionally, most current HSP treatments focus on symptomatic relief rather than disease modification, and oral muscle relaxants remain the standard of care for managing spasticity, as highlighted in clinical guidelines.

A 2023 study in Neurology and Therapy analyzed treatment patterns in HSP and found that over 80% of patients were initially prescribed oral antispastic medications, with baclofen being the most common. The study emphasized that while alternative routes (e.g., intrathecal or injectable) are used in severe cases, oral administration remains the first choice due to its practicality and established efficacy (Thompson et al., 2023).

Furthermore, the lack of approved non-oral disease-modifying therapies reinforces the dominance of oral drugs in the hereditary spastic paraplegia market. As research progresses, novel oral neuroprotective or gene-targeting therapies could further solidify this route’s leading position. Until then, the oral segment will continue to dominate due to its patient-friendly nature and alignment with current treatment paradigms.
