Zanaflex Properties
About Zanaflex
Zanaflex is a prescription muscle-relaxant pill that contains the active ingredient tizanidine, an α-2-adrenergic agonist. In Singapore, it is approved for the relief of muscle spasticity associated with conditions such as multiple sclerosis, spinal cord injury, and other neurological disorders. By dampening excessive neuronal firing, Zanaflex helps reduce muscle tone, easing pain and improving mobility for adults who struggle with involuntary muscle stiffness.
What is Zanaflex?
Zanaflex is the marketed brand of tizanine, sold by Pfizer as a short-acting oral tablet in 2 mg and 4 mg strengths. Classified as a centrally acting α-2-adrenergic agonist, it received approval from the Health Sciences Authority (HSA) in Singapore for the management of spasticity. The drug works by stimulating presynaptic α-2 receptors in the spinal cord, which inhibits the release of excitatory amino acids and decreases the firing of motor neurons.
How Zanaflex Works
Tizanidine binds to α-2 receptors located on the presynaptic terminals of interneurons in the dorsal horn. Activation of these receptors triggers a cascade that reduces calcium influx, thereby limiting the release of norepinephrine and other excitatory neurotransmitters. The net effect is a decrease in sympathetic outflow and a reduction of motor neuron hyperactivity. Clinically, patients notice a rapid onset of muscle relaxation within 30-60 minutes, with a duration of action lasting roughly 4-6 hours. Tizanidine is metabolized primarily by the liver enzyme CYP1A2 and eliminated via renal excretion, which informs dosing adjustments in hepatic or renal impairment.
Why Zanaflex is Used for Muscle Relaxant Conditions
- Spasticity in multiple sclerosis - By lowering excessive alpha-motor neuron firing, tizanidine directly counteracts the heightened muscle tone that characterises MS-related spasticity, often positioning it as a first-line adjunct to physical therapy.
- Post-traumatic spinal cord injury - The drug’s central action reduces spasm frequency, facilitating rehabilitation exercises and improving functional gains.
- Cerebral palsy-related spasticity (off-label) - Small trials suggest that low-dose tizanidine can soften limb stiffness, though it remains outside official Singapore guidelines.
- Comparison with baclofen - While baclofen acts on GABA-B receptors and has a longer half-life, Zanaflex offers a quicker onset and more flexible titration, making it preferable for patients who need rapid symptom control.
Off-Label and Investigational Uses of Zanaflex
Limited evidence from open-label studies indicates that tizanidine may alleviate neuropathic pain and reduce opioid requirements in postoperative settings. These uses have not been approved by the HSA, and clinicians should weigh potential benefits against risks such as hypotension and sedation. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Zanaflex Right for You?
Zanaflex is most appropriate for adults who experience moderate to severe spasticity that interferes with daily activities or rehabilitation. Patients with uncontrolled hypertension, severe liver disease, or a history of hypersensitivity to tizanidine should avoid the medication. Elderly individuals may require a lower starting dose (2 mg) because age-related reductions in hepatic clearance can increase plasma concentrations. Pregnant or breastfeeding women should discuss alternatives, as safety data in these populations remain limited.
Taking Zanaflex Effectively
- Timing: Take the tablet with a full glass of water, preferably on an empty stomach; food can reduce absorption by up to 20 %.
- Dose titration: Start at 2 mg once daily, increase by 2 mg at intervals of 3-5 days until the desired effect is achieved, not exceeding 12 mg per day.
- Missed dose: If a dose is forgotten for more than 12 hours, skip it and resume the regular schedule; do not double-dose.
- Drug interactions: Avoid concurrent use of strong CYP1A2 inhibitors such as fluvoxamine or ciprofloxacin, which can raise tizanidine levels and precipitate severe hypotension.
- Travel tip: Carry a written medication plan and a short supply in your hand luggage to prevent delays at customs.
Understanding Side Effects and How to Manage Them
- Common effects (dry mouth, drowsiness, hypotension): These arise from α-2-adrenergic stimulation in salivary glands and vascular smooth muscle. Drinking water frequently, avoiding alcohol, and rising slowly from seated positions can mitigate them.
- Sedation: Plan activities that require alertness when the drug’s peak concentration has passed (usually after 2-3 hours). If drowsiness persists, a lower dose or alternate dosing time (e.g., bedtime) may help.
- Serious reactions (hepatotoxicity, severe hypotension, bradycardia): Monitor liver function tests at baseline and periodically during therapy. Seek immediate medical attention if you experience fainting, rapid heartbeat, or jaundice.

Frequently Asked Questions
-
What should I do if I feel dizzy after taking Zanaflex? Dizziness is a common effect of α-2-adrenergic activation. Sit or lie down, hydrate, and avoid driving or operating machinery until the sensation resolves. If it persists, contact your prescriber for possible dose adjustment.
-
Can Zanaflex be combined with physical therapy? Yes. Reducing spasticity often enhances the effectiveness of stretching and strengthening exercises, allowing therapists to achieve greater range of motion.
-
Is there a risk of dependence? Tizanidine is not classified as addictive, but abrupt discontinuation after prolonged use may cause rebound hypertension. Taper the dose gradually under medical guidance.
-
How does Zanaflex differ from baclofen? Zanaflex acts on α-2 receptors, offering faster onset and easier titration, whereas baclofen targets GABA-B receptors and may cause muscle weakness at higher doses.
-
Will Zanaflex affect my blood pressure? The drug can lower systolic and diastolic pressures, especially when standing. Monitor your BP regularly, particularly during the first weeks of therapy.
-
Is Zanaflex safe for patients with kidney disease? Since renal excretion accounts for a minor portion of elimination, mild to moderate renal impairment usually does not require dosing changes, but severe dysfunction warrants physician oversight.
-
Can I take Zanaflex with alcohol? Combining alcohol with Zanaflex heightens sedation and hypotension risk; it is best avoided.
-
What laboratory tests are recommended while on Zanaflex? Baseline liver function tests (ALT, AST, bilirubin) and periodic monitoring thereafter help detect early signs of hepatotoxicity.
Glossary
- α-2-adrenergic receptor
- A G-protein coupled receptor that, when activated, inhibits norepinephrine release and reduces sympathetic outflow.
- Spasticity
- A velocity-dependent increase in muscle tone caused by an imbalance of excitatory and inhibitory signals in the central nervous system.
- Rebound hypertension
- A rapid rise in blood pressure that can occur after sudden cessation of an antihypertensive or centrally acting agent.
