In 2023, the global market size for muscle relaxant drugs was $4.46 billion, and it is projected to grow to $4.83 billion in 2024 at a compound annual growth rate (CAGR) of 8.2%. By 2028, the market is expected to reach $6.55 billion, growing at a CAGR of 7.9%[1].
Segmentation and Market Share
The muscle relaxant market is segmented by drug type, formulation, route of administration, and end-user. Norflex falls under the category of skeletal muscle relaxant drugs. Here are some key segments relevant to Norflex:
- By Drug Type: Skeletal muscle relaxant drugs, which include Norflex, are a significant segment within the muscle relaxant market.
- By Formulation: Norflex is available in various formulations, including tablets, extended-release tablets, and injections.
- By Route of Administration: Norflex can be administered orally or via injection.

Regional Market Performance
North America was the largest region in the muscle relaxant drugs market in 2023, indicating a strong demand for muscle relaxants like Norflex in this region. Other significant regions include Asia-Pacific, Western Europe, and Eastern Europe[1].
Financial Performance and Pricing
Cost and Pricing
The cost of Norflex can vary depending on the formulation and dosage. For example, 30 tablets of Norflex (100 mg) can average around $160, which translates to about $5.33 per day. This makes it potentially less expensive than some other muscle relaxants like Robaxin, especially at higher dosages[3].
Prescription Volume
In 2020, orphenadrine (Norflex) was prescribed to approximately 2 million individuals in the USA, accounting for nearly 4% of muscle relaxant prescriptions. This indicates a steady but not rapidly growing market share for Norflex within the muscle relaxant category[3].
Competitive Landscape
Norflex competes with other muscle relaxants such as Robaxin (methocarbamol) and Zanaflex (tizanidine). Here are some key differences and competitive aspects:
- Mechanism of Action: Norflex works within the central nervous system and has anticholinergic properties, distinguishing it from other muscle relaxants like Robaxin and Zanaflex, which have different mechanisms of action[3][5].
- Side Effects: Norflex tends to cause more anticholinergic side effects such as dry mouth compared to Robaxin, which could limit its use, especially among older adults[3].
- Prescription Volume: While Robaxin is more widely prescribed, with around 5 million prescriptions in the US in 2020, Norflex maintains a significant presence in the market[3].
Recent Developments and Acquisitions
In June 2023, Corona Remedies, an India-based pharmaceutical company, acquired the muscle relaxant brand Myoril from Sanofi India. Although this acquisition does not directly involve Norflex, it highlights the active and competitive nature of the muscle relaxant market in regions like India, which could influence the broader market dynamics[1].
Future Trends and Outlook
The muscle relaxant market, including Norflex, is expected to see strong growth driven by several factors:
- Multidisciplinary Pain Management: The increasing adoption of multidisciplinary approaches to pain management will drive the demand for muscle relaxants.
- Aging Population and Chronic Conditions: The growing aging population and the rise in chronic conditions will contribute to the market's growth.
- Advancements in Pain Management Therapies: Research in targeted therapies and advancements in pain management will further boost the market[1].
Key Takeaways
- The muscle relaxant market, which includes Norflex, is growing strongly, driven by shifts in treatment approaches and an aging population.
- Norflex is a significant player in the skeletal muscle relaxant segment, with a unique mechanism of action and side effect profile.
- The drug's financial performance is influenced by its pricing, prescription volume, and competitive landscape.
- Future growth will be driven by advancements in pain management and the increasing need for effective muscle relaxants.
