Fampridine, the first medicine designed to improve walking in adults with multiple sclerosis (MS), will now be routinely available on the NHS in England, NHS England has announced.The twice-daily pill, described as a "signal booster" therapy, is expected to benefit around 5,000 people living with MS in England during its first year of rollout.“Walking difficulties can have a huge impact on the freedom and independence of people with MS, so this signal-boosting pill could be life-changing for thousands of patients,” said Professor Frankie Swords, NHS National Medical Director.How Does Fampridine Work?Until now, treatment for MS-related walking difficulties has largely relied on physiotherapy, exercise, walking aids, foot-support devices, and treatments to manage muscle stiffness.According to Professor Swords, fampridine helps electrical messages travel along nerves damaged by MS, allowing some people to walk more easily and improve their mobility. For some patients, this could make everyday activities easier, from moving around the house and getting out independently to spending more time with family and friends.Also read: NHS To Roll Out Two 'Gamechanger' Tests for Faster Endometriosis Diagnosis: Know How They WorkEvidence Behind The DrugClinical trials found that fampridine (Fampyra) improved walking speed in 43% of patients and also helped people walk for longer.Patients will initially take the medicine for two to four weeks, with walking assessed before and after treatment.

It is also a chronic autoimmune disease in which the immune system attacks the brain and spinal cord.Symptoms vary from person to person and may come and go or worsen over time. MS can affect cognitive, emotional, motor, sensory, and visual functions. Symptoms may also worsen during heat exposure or infections such as urinary tract or respiratory infections.According to the MS International Federation, an estimated 2.8 million people worldwide live with MS, with women accounting for about 75% of cases globally.Common symptoms of MS include:Vision problemsDifficulty walking or maintaining balanceDifficulty thinking clearlyNumbness or weakness, especially in the arms and legsMuscle stiffnessDepressionProblems with sexual function or urinationFeeling very tired.
