Our Services

Hercon’s facility offers manufacturing, packaging and research & development opportunities. Hercon’s facility is both an FDA and DEA licensed facility.

With a large number of branded products coming off patent in the near future, there are many opportunities for developing generic transdermal deliveries for these drugs.

Hercon pursues strategic partnerships with other pharmaceutical companies that could benefit from our experience in transdermal drug delivery systems. This strategy allows both parties to reduce their capital expenditures.
