Inclusion Criteria
  • Diagnosis of severe primary axillary hyperhidrosis with a HDSS score of 3 or 4
  • At least 50 mg of sweat production in each axilla measured gravimetrically at room temperature and at a humidity consistent with the normal climate in that area over a period of 5 minutes (patients should have acclimatized to that room for at least 30 minutes)
  • Men and women aged 18 to 65 years at the time of informed consent with a body mass index of 18-32 kg/m2
  • Able to comply with protocol requirements, including overnight stays, blood sample collections as defined in the protocol subjects
  • Willing and able to provide written informed consent
Exclusion Criteria
  • Known allergy to any of the components in the investigational product.
  • Hypersensitivity against glycopyrrolate
  • Secondary hyperhidrosis, for example, hyperhidrosis that is secondary to other underlying diseases including hyperthyroidism, lymphoma and malaria, climacteric hyperhidrosis.
  • Previous surgical treatment of hyperhidrosis including sympathectomy, surgical debulking of the sweat glands, subcutaneous tissue curettage and ultrasonic surgery.
  • Botulinum toxin treatment in the prior 4 months.
  • Angle closure glaucoma or its precipitation (narrow angle).
  • Mycotic, other skin infections and other dermal disorder including infection at anticipated application sites in either axilla.
  • Any condition or situation that, in the investigator's or sub-investigator's opinion, may interfere with the patient's participation in the study

Hyperhidrosis Disease Severity Scale (HDSS)Screening, Day -1, Day 1 to 13, Day 16 of study period 1 and period 2

The Hyperhidrosis Disease Severity Scale (HDSS) is a disease-specific, quick, and easily-understood diagnostic tool that provides a qualitative measure of the severity of the patient's condition based on how it affects daily activities. HDSS is a four item scale. A score of 1 or 2 indicates mild or moderate Hyperhidrosis. A score of 3 or 4 indicates severe Hyperhidrosis.

Hyperhidrosis Quality of Life Questionnaire (HydroQoL)Day -1, Day 1 to 13 of period 1 and period 2

Hyperhidrosis Quality of Life Questionnaire (HydroQoL) is an 18-item, validated, Patient reported Outcome Hyperhidrosis Quality of life Instrument. It is devided into 2 Domains: A Daily Life Activities Domain (6 items) and a Psychosocial Domain (12 items). The items are scored on a 3-point scale (0=no, not at all, 1=a Little, 2=very much).
