Just Accepted "Just Accepted" manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides "Just Accepted" as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. "Just Accepted" manuscripts appear in full in PDF format accompanied by an HTML abstract. "Just Accepted" manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). "Just Accepted" is an optional service offered to authors. Therefore, the "Just Accepted" Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the "Just Accepted" Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or consequences arising from the use of information contained in these "Just Accepted" manuscripts. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 2 TABLE OF CONTENTS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 The configuration in which anti-solvent could be added at a variety of different locations along the tube length and at optimal flow rates was able to outperform previous designs in the literature which considered equally-spaced anti-solvent additions. The use of dynamic models to detect problems during startup of an MSMA-PFC was also highlighted.

The pharmaceutical industry faces multiple challenges (e.g., inefficient manufacturing techniques, quality control issues, and supply chain vulnerabilities) because of its current batch-wise approach to manufacturing. Recent regulatory support for continuous manufacturing and advances in continuous process technologies have caused an increase in interest from some drug manufacturers to modernize their production processes. However, many of these companies have focused on hybrid processes, where only certain steps are continuous, while others remain batch. Herein, the quality by design (QbD)-based design strategy and operation of an end-to-end integrated continuous manufacturing (ICM) pilot plant that produces both small-molecule active pharmaceutical ingredient (API) and oral solid dosages (OSDs) are discussed. Additionally, important quality and economic matters pertaining to scale-up and commercialization are addressed. ICM has significant benefits, including better quality control, increased supply chain flexibility, a lower capital investment (in the example provided, a ∼ 90% reduction), and lower operating costs (in the example provided, a 33.6% reduction for API and 29.4% reduction for tablets).

The continuous reactive crystallization of an active pharmaceutical ingredient (API) in a plug flow reactor (PFR)-continuous stirred tank reactor (CSTR) cascade system with in-line PATs was developed and investigated. Residence...
