Flexura D Tablet (Diclofenac Potassium 50mg + Metaxalone 400mg) | Painkiller and Muscle Relaxant
Flexura D Tablet (Diclofenac Potassium 50mg + Metaxalone 400mg) is a combination medication containing a non-steroidal anti-inflammatory drug (NSAID) and a muscle relaxant, used to relieve pain, inflammation, and muscle spasms associated with musculoskeletal conditions. Diclofenac Potassium works by blocking the production of prostaglandins, chemicals responsible for causing pain and inflammation in the body, while Metaxalone acts on the central nervous system to relax tense and spastic muscles, providing relief from muscle stiffness and discomfort.
Product Overview
Flexura D Tablet is a high-potency combination medication containing Diclofenac Potassium and Metaxalone, specifically engineered to treat acute, painful musculoskeletal conditions. By combining a fast-acting Non-Steroidal Anti-Inflammatory Drug (NSAID) with a targeted skeletal muscle relaxant, this tablet provides a dual-action approach to pain management. It effectively disrupts the cycle of pain and muscle spasticity, allowing for improved mobility and faster recovery from strains, sprains, and other muscle-related injuries.
Product Composition
- Diclofenac Potassium (50 mg): A potassium salt form of diclofenac that is absorbed more rapidly than the sodium version, providing quicker analgesic and anti-inflammatory action.
- Metaxalone (400 mg): A centrally acting muscle relaxant that works by modulating nerve impulses in the brain and spinal cord.
Product Specification
| Feature | Details |
| Drug Class | NSAID + Skeletal Muscle Relaxant |
| Therapeutic Indications | Muscle Spasms, Acute Musculoskeletal Pain, and Inflammation |
| Formulation | Oral Tablet |
| Onset of Action | Rapid (typically within 30–60 minutes) |
| Metabolism | Primarily hepatic (Liver) |
| Excretion | Renal (Urine) and Biliary (Feces) |
Mechanism of Action
- Prostaglandin Inhibition: Diclofenac Potassium works by inhibiting the cyclooxygenase (COX-1 and COX-2) enzymes. This action reduces the production of prostaglandins, which are the chemical messengers responsible for signaling pain and causing inflammation at the site of injury.
- Central Nervous System Depression: Unlike direct muscle acting agents, Metaxalone does not act directly on the skeletal muscle. Instead, it acts on the central nervous system (CNS) to produce a sedative effect and interrupt the pain-spasm-pain cycle.
- Synergistic Relief: The combination ensures that while the muscle relaxant addresses the physical tension and spasticity, the NSAID simultaneously treats the underlying swelling and chemical pain triggers.
Key Benefits
- Dual-Action Therapy: Treats both the physiological pain (inflammation) and the physical symptom (muscle stiffness) in a single dose.
- Faster Recovery: By reducing muscle spasms, it allows patients to engage more effectively in physical therapy and return to daily activities sooner.
- Rapid Pain Control: The use of the potassium salt of Diclofenac ensures a quicker onset of action, making it ideal for acute, sharp pain.
- Improved Mobility: Effectively relaxes "locked" or "tight" muscles associated with lower back pain or neck strains.
- Convenient Dosing: Reduces the pill burden for patients who would otherwise need to take separate anti-inflammatory and muscle relaxant medications.
