Efficacy and safety of methantheline bromide (Vagantin(®) ) in axillary and palmar hyperhidrosis: results from a multicenter, randomized, placebo-controlled trial.

Abstract

BACKGROUND:

Focal hyperhidrosis can severely affect quality of life. So far, knowledge on the effect of systemic therapy of focal hyperhidrosis is limited.

OBJECTIVE:

To assess the efficacy and safety of methantheline bromide (MB) in the treatment of axillary and palmar-axillary hyperhidrosis.

METHODS:

A multicenter controlled randomized double-blind clinical trial was conducted in patients with axillary or palmar-axillary hyperhidrosis defined by a sweat production >50 mg/5 min. Patients received 3 × 50 mg MB daily or placebo over a period of 28 ± 1 days. Main outcome criterion was the reduction of sweat as measured by gravimetry on day 28 ± 1. Quality of life was assessed by Dermatology Life Quality Index (DLQI) and Hyperhidrosis Disease Severity Score (HDSS).

RESULTS:

A total of 339 patients were randomly assigned to receive MB or placebo. On day 28 ± 1, the mean axillary sweat production was 99 mg for MB and 130 mg for placebo compared with 168 mg and 161 mg respectively at baseline (P = 0.004). Patient's HDSS score decreased in the MB group from 3.2 to 2.4 compared with 3.2 to 2.7 for placebo (P = 0.002). Similar results could be obtained for the DLQI with 9.7 for MB and 12.2 for placebo, which decreased from 16.4 or 17 respectively (P = 0.003). Tolerability was good for both groups. The most frequent adverse event was dry mouth.

CONCLUSION:

Fifty milligrams methantheline bromide three times a day is an effective and safe treatment of axillary hyperhidrosis.
