QBREXZA

AbsorptionThe pharmacokinetics of glycopyrronium were evaluated in adult and pediatric patients with primary axillary hyperhidrosis following Qbrexza once daily applied to the axillae for 5 days. The mean ± SD exposures of glycopyrronium are presented in Tables 3 and 4. There was no evidence of accumulation.

14.1 Efficacy and Safety Trials Two randomized, vehicle-controlled multicenter trials,

Trial 1(NCT02530281) and

Trial 2(NCT02530294), were conducted in subjects with primary axillary hyperhidrosis and enrolled a total of 697 subjects 9 years of age or older. Inclusion criteria required that prior to the start of treatment, all subjects produce at least 50 mg of sweat in each axilla over a 5-minute period and rate the severity of their sweating daily over a week with a mean score of 4 or higher on the ASDD item #2, a patient reported outcome instrument scored from 0 (no sweating) to 10 (worst...

The following adverse reactions are described in greater detail in other sections

• New or Worsening Urinary Retention [see Warnings and Precautions ( 5.1 )] Most common adverse reactions (incidence ≥2%) are dry mouth, mydriasis, oropharyngeal pain, headache, urinary hesitation, vision blurred, nasal dryness, dry throat, dry eye, dry skin, constipation. Local skin reactions, including erythema, burning/stinging and pruritus were also common (>5%) ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, c...

Qbrexza is contraindicated in patients with medical conditions that can be exacerbated by the anticholinergic effect of Qbrexza (e.g., glaucoma, paralytic ileus, unstable cardiovascular status in acute hemorrhage, severe ulcerative colitis, toxic megacolon complicating ulcerative colitis, myasthenia gravis, Sjogren’s syndrome). Qbrexza is contraindicated in patients with medical conditions that ca...

New or worsening urinary retention: Use with caution in patients with a history of documented urinary retention ( 5.1 ). Control of body temperature: In the presence of high ambient temperature, heat illness may occur; avoid use if patients develop generalized lack of sweating when exposed to hot or very warm environmental temperatures ( 5.2 ). Operating machinery or an automobile: Transient blurred vision may occur with use of Qbrexza. If blurred vision occurs, discontinue use of Qbrexza until ...

7 DRUG INTERACTIONS Coadministration of Qbrexza with anticholinergic medications may result in additive interaction leading to an increase in anticholinergic adverse effects. Avoid coadministration of Qbrexza with other anticholinergic-containing drugs ( 7 ) 7.1 Anticholinergics Coadministration of Qbrexza with anticholinergic medications may result in additive interaction leading to an increase i...
