For Pharmacists:

Medicine Name: Analar
Brand: Analar
Active Ingredient(s): Tizanidine

Indications:
Indicated for the management of muscle spasticity due to multiple sclerosis and spinal cord injuries.

Pharmacodynamics:
Mechanism of Action:
Tizanidine is a selective alpha-2 adrenergic agonist, which reduces muscle spasm by inhibiting the release of excitatory neurotransmitters in the central nervous system.

Pharmacological Effects:
Tizanidine acts as a muscle relaxant and analgesic by relaxing muscles and reducing spasm-induced pain.

Receptor Binding:
Tizanidine primarily binds to alpha-2 adrenergic receptors, which helps reduce muscle tone and spasm. This mechanism also decreases the release of neurotransmitters like glutamate.

Pharmacokinetics:

• Absorption: Rapidly absorbed after oral administration, with peak plasma concentration occurring within 1–2 hours.
• Distribution: Plasma protein binding is about 30%.
• Metabolism: Metabolized primarily in the liver via the CYP1A2 enzyme system.
• Elimination: Excreted mainly in urine, with a small amount in feces.
• Half-Life: Approximately 2.5 hours.
• Bioavailability: Approximately 34%.
• Time to Peak Concentration: 1–2 hours.
• Effect of Food: Food does not significantly affect the absorption of Tizanidine but may slightly delay peak concentration.

Dosage and Administration:

• Adults: Start with 2mg three times a day. The maximum dose is 12mg per day, divided into multiple doses.
• Pediatric: Not typically recommended for children.
• Special Populations: Reduce dose for patients with renal or hepatic impairments.

Contraindications:

• Known hypersensitivity to Tizanidine or its excipients.
• Contraindicated in patients with severe liver disease.

Warnings and Precautions:
Use with caution in patients with hypotension, bradycardia, or renal impairment. Monitor for drowsiness and hypotension.

Drug-Drug Interactions:
Potential interactions with CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin) may increase the risk of Tizanidine toxicity. Avoid concomitant use with beta-blockers and other antihypertensive drugs.

Drug-Food Interactions:
Food may slightly delay absorption but does not significantly affect the drug’s therapeutic effects.

Adverse Reactions:

• Common: Dizziness, dry mouth, fatigue, and hypotension.
• Serious: Severe liver toxicity, respiratory depression, and extreme sedation.

Therapeutic Effects:
Effective in relieving muscle spasm, reducing spasticity, and managing pain associated with muscle contractions.

Storage:
Store at room temperature (20-25°C) in a tight, light-resistant container.

Packaging:
Available in tablet form, typically in 10 tablets per pack.

Clinical Considerations:

• Pregnancy Category: C (Risk cannot be ruled out)
• Lactation Category: Use with caution as it is excreted in breast milk.
• Pediatric Category: Not recommended.
• Geriatric Category: Caution is advised due to possible reduced renal or hepatic function.
• Adult Category: Safe when used as directed.
• Child Category: Not indicated for children.

Other Consideration:
Monitor patients for signs of sedation, especially if combined with alcohol or other sedatives.

Conclusion:
Analar (Tizanidine) is an effective muscle relaxant for managing conditions like spinal cord injury and multiple sclerosis. It works by reducing muscle spasms and pain, improving the quality of life for patients. However, it is important to follow prescribed dosages carefully and be mindful of possible side effects and interactions with other drugs.
