title: Safety and efficacy of adapalene gel 0.1% in acne vulgaris: results of a post-marketing surveillance study.
abstract: BACKGROUND
  Adapalene is a novel retinoid indicated for the topical treatment of acne vulgaris. The drug was introduced in India in 2001.
  
  
  OBJECTIVE
  A post-marketing surveillance study was conducted to assess the safety and efficacy of adapalene gel 0.1% when used as monotherapy or in combination with other anti-acne agents in Indian patients of acne vulgaris.
  
  
  METHODS
  A 12-week, multicentre, open-label, non-comparative study involving 571 patients from 21 centers across India was conducted between January and September of 2002. Concomitant prescription of other anti-acne drugs was permitted, if needed.
  
  
  RESULTS
  Of the 571 patients, 441 completed the treatment as per protocol. At the end of therapy, 96.3% of patients showed an improvement in their acne from baseline, with greater than 75% improvement seen in two-thirds of patients. Adverse events were reported in 24% of the patients, none of which were serious. The tolerability of therapy was rated as excellent/good in 81% of patients by physicians and in 78% by the patients.
  
  
  CONCLUSIONS
  Adapalene gel 0.1% is a safe and effective topical agent in the treatment of mild to moderate acne vulgaris in Indian patients. It may be safely combined with other topical and oral anti-acne agents.
