Understanding the Root Cause of Walking Difficulties
Before exploring specific medications, it's crucial to understand that there is no universal "best medicine for walking." Walking impairment can stem from a wide range of issues, including vascular problems, neurological disorders, or musculoskeletal pain. The effectiveness of any pharmacological intervention depends on an accurate diagnosis from a healthcare professional. Difficulties with gait can manifest as pain during exercise, weakness, poor balance, stiffness, or shuffling. Identifying the source of the problem is the first and most critical step toward finding an effective treatment.
Medications for Walking Pain from Peripheral Artery Disease (PAD)
Peripheral Artery Disease (PAD) is a condition where narrowed arteries reduce blood flow to the limbs, most commonly the legs. This often causes muscle pain and cramping during physical activity like walking, a symptom known as intermittent claudication (IC) [1.8.1].
Cilostazol
Cilostazol is a primary medication prescribed to improve walking distance in patients with IC [1.3.6]. It works as a phosphodiesterase-3 inhibitor, which helps to widen arteries, improve blood flow, and inhibit platelet aggregation [1.4.2, 1.4.3]. Clinical guidelines recommend cilostazol for improving walking performance in people with symptomatic PAD [1.4.5]. Studies have shown that it can significantly increase both the distance a person can walk before feeling pain (initial claudication distance) and the total distance walked before needing to stop (absolute claudication distance) [1.3.3, 1.4.6]. It may take 2 to 4 weeks to notice improvements, and sometimes as long as three months [1.4.4]. Common side effects include headache, diarrhea, dizziness, and palpitations [1.4.1]. Cilostazol is contraindicated in patients with heart failure [1.3.6].
Pentoxifylline
Pentoxifylline is another medication used for IC. It aims to improve blood flow by making the blood less thick and sticky, which helps it move more easily through narrowed vessels [1.3.1]. However, its efficacy is a subject of debate. While some studies suggest it may offer a modest improvement in walking distance compared to a placebo, a 2020 Cochrane Review concluded there is a lack of high-certainty evidence for its effects, and its role remains uncertain [1.3.1, 1.8.1]. Current guidelines often do not recommend pentoxifylline for intermittent claudication due to inconsistent results [1.3.6].
Neurological Conditions Affecting Gait
Certain neurological disorders directly impact the nerve signals that control muscles, leading to significant walking challenges.
Dalfampridine for Multiple Sclerosis (MS)
Dalfampridine (brand name Ampyra) is an oral medication specifically indicated to improve walking in adults with Multiple Sclerosis (MS) [1.5.1]. MS affects mobility in over 80% of patients [1.2.3]. Dalfampridine is a potassium channel blocker that helps improve the conduction of nerve signals in demyelinated nerve fibers [1.5.4, 1.5.5]. In clinical trials, patients who responded to the drug increased their walking speed by an average of about 25% [1.5.3]. It's important to note that not every patient responds to the therapy [1.5.3]. Dalfampridine is taken as a 10 mg tablet twice a day, and it can be used alone or with other MS disease-modifying therapies [1.5.4]. Common side effects include urinary tract infections, trouble sleeping, dizziness, headache, and nausea [1.9.4].
Levodopa for Parkinson's Disease (PD)
For individuals with Parkinson's disease, walking difficulties like shuffling, stiffness, and freezing of gait are common motor symptoms. Levodopa, often combined with carbidopa (e.g., Sinemet), remains the most effective medication for treating these motor symptoms [1.6.4, 1.6.5]. Levodopa is a chemical precursor to dopamine, a neurotransmitter that is deficient in the brains of PD patients [1.6.4]. By replenishing dopamine levels, levodopa improves overall motor control, which includes gait and balance [1.6.2]. Studies show that when patients are on medication, they increase their gait speed by improving step length and timing [1.6.2]. Other medications for PD that can help with motor symptoms include dopamine agonists, MAO-B inhibitors, and COMT inhibitors [1.6.5].
Managing Walking Pain from Arthritis
For many, walking is painful not because of vascular or neurological issues, but due to joint inflammation and damage from arthritis. In these cases, the 'best' medicine is one that manages pain and inflammation, making movement more tolerable.
Over-the-Counter (OTC) Pain Relievers
Nonsteroidal anti-inflammatory drugs (NSAIDs) are a first-line treatment for many types of arthritis pain. They work by reducing both pain and inflammation [1.7.3]. Common OTC options include:
- Ibuprofen (Advil, Motrin) [1.7.1]
- Naproxen Sodium (Aleve) [1.7.1]
Acetaminophen (Tylenol) is another option that can relieve mild to moderate pain, but it does not have the anti-inflammatory effects of NSAIDs [1.7.5]. It may be a safer choice for individuals with heart or kidney conditions who cannot take NSAIDs [1.7.4].
Topical creams and gels containing NSAIDs (like diclofenac, available as Voltaren), capsaicin, or menthol can also provide localized relief when applied directly to the painful joint [1.7.1, 1.7.5].
Comparison of Walking Medications
| Medication | Primary Condition Treated | Mechanism of Action | Common Side Effects |
|---|---|---|---|
| Cilostazol | Peripheral Artery Disease (PAD) | Widens arteries, improves blood flow [1.4.2] | Headache, diarrhea, dizziness, palpitations [1.4.1] |
| Dalfampridine | Multiple Sclerosis (MS) | Improves nerve signal conduction [1.5.4] | UTI, insomnia, dizziness, headache [1.9.4] |
| Levodopa | Parkinson's Disease (PD) | Converts to dopamine in the brain [1.6.4] | Nausea, lightheadedness, involuntary movements [1.6.4] |
| NSAIDs (e.g., Ibuprofen) | Arthritis / Musculoskeletal Pain | Reduce pain and inflammation [1.7.3] | Stomach upset, cardiovascular/kidney issues [1.7.5] |

Conclusion: A Personalized Approach is Essential
Ultimately, there is no single best medicine for improving walking for everyone. The most effective treatment is one that is tailored to the specific underlying condition causing the difficulty. Cilostazol helps patients with PAD walk farther, dalfampridine can increase walking speed for some with MS, levodopa remains a cornerstone for motor control in Parkinson's, and NSAIDs provide essential pain relief for those with arthritis. A comprehensive evaluation by a healthcare provider is the only way to determine the correct diagnosis and the safest, most effective pharmacological plan, which is often combined with non-medical interventions like physical therapy and exercise.
