Q: What precautions should be taken when using Unitopa Tablets (Topiramate)?

This drug is used in the treatment of epilepsy and migraine prevention. There may be an increased risk of suicidal thoughts or behaviors during the use of this drug, so patients and caregivers should immediately inform healthcare providers of any changes in mood or symptoms of depression. This drug can cause serious skin reactions, and if there are severe rashes or abnormalities on the skin or mucous membranes, immediately discontinue use and consult with healthcare professionals. Patients with hypersensitivity or issues with lactose digestion should not take this drug, and women who are pregnant or planning to become pregnant should consult a physician before using this drug and use effective contraception. Patients with impaired kidney function may need dosage adjustments due to delayed excretion of the drug, and patients at risk for kidney stones should ensure adequate fluid intake to prevent stone formation. This drug can cause central nervous system side effects like drowsiness, dizziness, and decreased concentration, so it is advisable to avoid driving or operating machinery during the initial dose. When discontinuing the drug, do not stop suddenly, but gradually taper off following the physician's instructions to reduce the risk of seizures. This drug may interact with other antiepileptic medications or various drugs, so patients should inform their healthcare providers or pharmacists about any other medications they are taking. If a pregnant woman takes this drug, there is a risk of malformations or growth retardation in the fetus, therefore, its use during pregnancy should be carefully considered, and alternative treatment methods should be contemplated as much as possible. Regular medical check-ups are important during the use of this drug to monitor for adverse reactions, especially mental health conditions and kidney status.

Question 2

What are the dosage and administration instructions for Unitopa Tablets (Topiramate)?

Accepted Answer

It is preferable to start this medicine at a low dose and increase it to the effective dose.

There is no need to monitor blood concentrations to optimize the dosage of this medicine.

The recommended dose of this medicine applies to all adults and children, including the elderly, provided they do not have renal disease.

It may be administered with or without food.

The tablets should be swallowed whole and not crushed.

1. Epilepsy
1) Monotherapy: When discontinuing other concomitant antiepileptic medicines in order to administer topiramate as monotherapy, consider the potential effect on seizure control. Unless other antiepileptic medicines must be discontinued immediately for safety reasons, gradually reduce and discontinue the other antiepileptic medicines by approximately 1/3 at 2-week intervals (see “5. General Precautions” under Precautions for Use).
When enzyme-inducing medicines are discontinued, topiramate concentrations may increase. If a clinically significant increase in topiramate concentration occurs, the dose of this medicine may need to be reduced.
Adults (17 years and older):
Start with 25㎎ in the evening during the first week. Thereafter, increase the dose by 25 or 50㎎ daily at 1-2 week intervals and administer in 2 divided doses. If the patient has difficulty tolerating this rate of dose increase, lengthen the interval between increases. The dose and rate of increase should be determined according to clinical response. The recommended dose for monotherapy in adults is 100～200mg daily. The maximum recommended dose is 500㎎ daily. Some patients with recurrent epilepsy have tolerated up to 1,000㎎ of topiramate daily as monotherapy.
2) Adjunctive therapy
Adults (17 years and older)
The minimum effective dose is 200mg daily, and the usual dose is 200-400mg daily in 2 divided doses. Depending on the patient, the dose may be increased to the maximum recommended dose of 800mg daily. Start treatment with 25-50mg in the evening during the first week; treatment may also be started at a lower dose. Thereafter, increase the dose by 25-50mg at 1-2 week intervals and administer in 2 divided doses. If the patient has difficulty tolerating the increased dose, the dose increase may be smaller or the interval between increases may be extended. The dose should be determined according to clinical effect.

2. Prevention of migraine
Adults: Start with 25mg of this medicine in the evening during the first week. Thereafter, increase the dose by 25mg/day at 1-week intervals. If the patient has difficulty tolerating this increase, lengthen the interval between increases. The recommended dose is 100mg daily, administered in 2 divided doses. Some patients may respond to a dose of 50mg daily. The dose may be increased to 200mg daily, and the dose and rate of increase should be determined according to clinical response.

3. Patients with renal impairment
- For patients with moderate or severe renal impairment (CLcr < 70 mL/min/1.73 m2), it is recommended that the starting and maintenance doses be reduced to approximately 1/2.
- Hemodialysis patients: Since this medicine is removed from plasma by hemodialysis, increase the dose of this medicine by approximately 1/2 on dialysis days. Increase the dose taking into account the duration of dialysis, dialyzer clearance, and the patient's renal clearance, and administer divided doses at the start and end of hemodialysis.

4. Patients with hepatic impairment
Use this medicine with caution in patients with hepatic impairment, as clearance of this medicine may be reduced.

Answer

Children (6-16 years): Start with 0.5-1㎎/㎏ in the evening during the first week. Thereafter, increase the dose by 0.5-1㎎/㎏ daily at 1-2 week intervals and administer twice daily. If the patient has difficulty tolerating the increase, reduce the size of the dose increments or lengthen the interval between increases. The dose and extent of increase should be determined according to clinical response. The recommended dose for monotherapy in children is 3-6mg/kg daily. Doses up to 500㎎ daily have been used in children diagnosed with partial seizures.
Children (2-16 years): The recommended daily dose is approximately 5-9mg/kg, administered in 2 divided doses. During the first week, administer 25mg (or less, based on 1-3mg/kg daily) in the evening. Thereafter, increase the dose by 1-3mg/kg daily at 1-2 week intervals until an appropriate clinical effect is achieved, and administer in 2 divided doses. Dose titration should be determined according to clinical effect. Doses up to 30mg/kg daily have been administered and were generally well tolerated.
