  • Stability test of novel combined formulated dry powder inhalation system containing antibiotic: physical characterization and in vitro-in silico lung deposition results.: This study investigates a novel dry powder inhalation system formulated with an antibiotic and sodium stearate. It explores the physical characterization and lung deposition efficiency, demonstrating the potential for enhanced drug delivery to the lungs (Benke et al., 2019).

  • Protective effect of sodium stearate on the moisture-induced deterioration of hygroscopic spray-dried powders.: This research highlights the role of sodium stearate in protecting hygroscopic spray-dried powders from moisture-induced degradation, which is crucial for maintaining the stability and efficacy of pharmaceutical products (Yu et al., 2018).

  • Dissolution of a poorly water-soluble drug dry coated with magnesium and sodium stearate.: This study examines the use of sodium stearate in enhancing the dissolution rates of poorly water-soluble drugs, which is critical for improving drug bioavailability (Tay et al., 2012).

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
