Second Supplement to USP 40–NF 35 Online: Timolol Maleate

Type of Posting: Publication Correction

Posting Date: 30–Jun–2017

USP recently discovered an error with Timolol Maleate as it appears in Second Supplement to USP 40‒NF 35 in USP–NF Online. A revision to Timolol Maleate was published in First Supplement to USP 40‒NF 35. The changes appearing in First Supplement revision were inadvertently removed from the version published in Second Supplement to USP 40–NF 35 online. The PDF file available from the USP–NF Online and the print USP-NF are not affected by the error and are the correct version.

The correct version of the Timolol Maleate monograph can be accessed in the online product via the print PDF, as well as here. The file will be corrected and updated via Errata to become official on August 1, 2017 and incorporated in the online, print, and flash drive products in USP 41–NF 36.

USP apologizes for any inconvenience this may have caused.
