To help clients meet the United States Food and Drug Administration (FDA) drug labeling requirements, Freyr provides the service of converting the current labeling content into the required Structured Labeling (SPL) format, adhering to the Physician Labeling Rule (PLR) Compliance, Drug Registration, and Listing.

  • PLR Conversions

PLR is intended to provide healthcare professionals with clear and concise prescribing information and to better manage the risks of medication use and reduce medical errors. It also makes prescription information more accessible for use with electronic prescribing tools and other electronic information resources.

Bound by a federal mandate, the FDA labeling requirement details that all NDAs, BLAs, and Efficacy Supplements submitted after June 30, 2006, conform to the SPL-PLR rule. In addition, all NDAs, BLAs, and Efficacy Supplements approved after June 30, 2001, must be converted to the SPL-PLR format during a seven (07)-year implementation period.

  • Pregnancy Lactation Labeling Rule (PLLR) Conversions

Recent changes to the US FDA drug labeling requirements for pregnant and lactating women make prescribing more complex than it used to be, but the information will be far more complete and much more current.

The new PLLR has been designed to help prescribers assess the benefits and risks of medication for pregnant and lactating women. In contrast to the old system, the prescribers have used letter categories A, B, C, D, and X to evaluate the safety precautions.

The US labeling requirement in the form of PLR is intended to make information on prescription drugs easier to read. For example, labels now include a "highlights" section containing bulleted information, a table of contents, warnings in bold font, and other useful information. However, the rule only applies to products approved under a New Drug Application (NDA), Biologics Licensing Application (BLA), or Efficacy Supplement (ES) between 2001 and June 30, 2006, as well as all products thereafter.

  • Structured Product Labeling (SPL)

The FDA mandates the filing of product labeling information in the SPL format. Many pharmaceutical developers, therefore, have determined the need for a reliable service provider that will enable them to meet the Regulatory compliance guidelines without straining their current business practices.

Depending on the context and FDA’s labeling requirements, Freyr recreates or efficiently utilizes your current labeling content and transforms this readily available content into the required SPL R4 or the PLR-compliant format.
