Mydocalm Forte (Tolperisone Hydrochloride)

Tolperisone is used to manage conditions involving abnormal muscle tone and pain within the musculoskeletal and neurological domains.

• Muscle spasm: Reduces involuntary muscle contraction and associated discomfort.
• Skeletal muscle pain: Alleviates pain related to muscle overuse or strain.
• Spasticity associated with neurological disorders: Decreases muscle hypertonia and improves mobility in conditions such as multiple sclerosis or post‑stroke spasticity.

• Tolperisone acts centrally by inhibiting voltage‑gated sodium channels in spinal cord neurons and reducing the activity of muscle spindle afferents. This dual action diminishes the reflex excitation of skeletal muscles, leading to a decrease in muscle tone and hypertonia without significant sedation. The drug’s effect is mediated through modulation of neuronal excitability rather than direct peripheral muscle relaxation.

Tolperisone may be associated with a range of adverse reactions, which are generally categorized by frequency and severity.

Common Side Effects

• Dizziness
• Nausea
• Dry mouth
• Headache
• Hypotension

Serious or Rare Side Effects

• Severe allergic reactions (e.g., rash, angioedema, anaphylaxis)
• Hepatotoxicity (elevated liver enzymes)
• Blood dyscrasias (e.g., neutropenia, agranulocytosis)
• Cardiac arrhythmias

When prescribing Tolperisone, clinicians should consider several precautionary measures to ensure patient safety.

• Renal impairment: Monitor renal function and adjust therapy if necessary.
• Hepatic dysfunction: Use with caution and observe liver enzyme levels.
• Elderly patients: Assess fall risk due to possible dizziness or hypotension.
• Concomitant CNS depressants: Increased risk of sedation and impaired coordination.
• Pregnancy and lactation: Safety not established; avoid use unless clearly indicated.
• Store at ambient temperature: Keep in the original packaging, protect from moisture and direct sunlight.

Tolperisone can interact with other medications, influencing its efficacy or safety profile.

Major Interactions (Avoid)

• Concomitant use with other muscle relaxants: May cause additive muscle weakness and profound sedation.
• Potassium channel blockers: Increased risk of cardiac arrhythmias.

Moderate Interactions (Monitor Closely)

• CYP450 enzyme inhibitors: Potentially raise Tolperisone plasma concentrations.
• Antihypertensive agents: May enhance hypotensive effects.
• Alcohol: Can increase central nervous system depression.
• Antidepressants (e.g., SSRIs): May potentiate dizziness or sedation.
