TOPAMAX should be initiated at 25 to 50 mg/day, followed by titration to an effective dose in increments of 25 to 50 mg/day every week. Consequently, the plasma drug concentration for the same mg/kg/day dose would be lower in pediatric patients compared to adults and also in younger pediatric patients compared to older pediatric patients. The studies described in the following sections were conducted using TOPAMAX (topiramate) Tablets. Symptoms include acute onset of decreased visual acuity and/or ocular pain.

Sodium valproate, at 500 g/mL (a concentration 5 to 10 times higher than considered therapeutic for valproate) decreased the protein binding of topiramate from 23% to 13%. The no-effect dose (20 mg/kg/day) for embryofetal developmental toxicity in rabbits is equivalent to the MRHD for epilepsy and approximately 4 times the MRHD for migraine on a mg/m2 basis. A drug-drug interaction study conducted in patients with type 2 diabetes evaluated the steady-state pharmacokinetics of glyburide (5 mg/day) alone and concomitantly with topiramate (150 mg/day).

Drink plenty of fluids during the day to prevent kidney stones while taking TOPAMAX. TOPAMAX is a carbonic anhydrase inhibitor. We conducted a single-blind, parallel group, randomized, controlled trial to compare the effectiveness and safety of the new alfa1-blocker silodosin versus the established drug tamsulosin in symptomatic BPH. The most common ( 2% more frequent than low-dose 50 mg/day TOPAMAX) adverse reactions causing discontinuation were difficulty with memory, fatigue, asthenia, insomnia, somnolence, and paresthesia. The incidence of hyperammonemia in pediatric patients 12 to 17 years of age in the preventive treatment of migraine trials was 26% in patients taking TOPAMAX monotherapy at 100 mg/day, and 14% in patients taking TOPAMAX at 50 mg/day, compared to 9% in patients taking placebo.

Somnolence and fatigue were the adverse reactions most frequently reported during clinical trials of TOPAMAX for adjunctive epilepsy. In a double-blind study in 90 pediatric patients 6 to 11 years of age (including 59 topiramate-treated and 31 placebo patients), the adverse reaction profile was generally similar to that seen in pooled double-blind studies of pediatric patients 12 to 17 years of age. Warnings Topamax may cause vision problems that can be permanent if not treated quickly. The effect of TOPAMAX on growth and bone-related sequelae has not been systematically investigated in long-term, placebo-controlled trials. No age-related differences in effectiveness or adverse effects were evident. Clinical laboratory results indicated decreases in serum potassium after topiramate or HCTZ administration, which were greater when HCTZ and topiramate were administered in combination.

The actual adjustment should take into account 1) the duration of dialysis period, 2) the clearance rate of the dialysis system being used, and 3) the effective renal clearance of topiramate in the patient being dialyzed [see Use In Specific Populations, CLINICAL PHARMACOLOGY]. In pregnant rabbits administered topiramate (0, 20, 60, and 180 mg/kg/day or 0, 10, 35, and 120 mg/kg/day) orally during organogenesis, embryofetal mortality was increased at 35 mg/kg/day, and increased incidences of fetal malformations (primarily rib and vertebral malformations) were observed at 120 mg/kg/day.
