A drug receives Resolved status when the Drug Shortages Staff DSS determines that the market is covered, based on information from all manufacturers. The market is considered covered when supply is available from at least one manufacturer to cover total market demand. However, some manufacturers may not have all presentations available. DSS monitors the supply of products with Resolved status. For the most current supply information, contact the manufacturers.
The lidocaine peaks were verified as spectrally pure using the HPLC system equipped with photodiode array detection. Forced degradation of lidocaine in the presence of diphenhydramine and aluminum hydroxide-magnesium hydroxide-simethicone by 0. The linear range of the assay was 0.
Some Hospira Products Get 'New Use Dates' While Others Get Recalled
Acceptable linearity, as designated by the correlation coefficient r 2was demonstrated within the intended calibration range for the assay. These data yielded an r 2 of 0. In addition, the data showed a random distribution of residuals. Despite the chromatographic changes induced by the three challenges, data from these conditions indicated method robustness.
These three challenges included adjusting the mobile phase gradient, increasing the column temperature, and increasing the mobile phase flow rate. These challenges were chosen based on their anticipated negative effects on resolution and theoretical plates. The RSD for lidocaine response was 0. Stability data for lidocaine with diphenhydramine and aluminum hydroxide-magnesium hydroxide-simethicone in all experimental groups are shown in Table 1.
These data are presented as the calculated concentrations in the syringe, based on their dilution factor. Calculated concentrations are determined by comparing them against a fresh calibration curve run on each day of analysis, prepared using the USP lidocaine reference standard and mobile phase diluent. Finally, the percent remaining of the initial concentration was calculated for each formulation and the control Table 1. Lidocaine, diphenhydramine, and aluminum hydroxide-magnesium hydroxide-simethicone at a ratio of Finally, the stability data underwent a 2-way analysis of variance ANOVA with Bonferroni post-test with an a priori level of significance of 0.
Immediately after compounding, each mouthwash formulation displayed an opaque, light-pink appearance, which did not change over the course of the study. The appearance of the product was visually examined daily when the samples were expelled into the scintillation vials for dilution, before the addition of mobile phase. No particulate matter was detected in the samples after ejection from the syringes.
Finally, the pH of the preparations did not change significantly during the course of the study. Immediately after compounding, formulation A had a pH of 7.
After 90 days, formulations A and B had pH values of 8. The control product maintained a pH of approximately 6, with a reading of 6. Based on the calculated percentages versus initial concentration and the results from ANOVA comparing formulations A and B, a BUD of 21 days is deemed appropriate for both magic mouthwash formulations.
Although formulation A nominally retained a higher percentage of the initial lidocaine concentration longer than did B, the percent of the initial concentration remaining at 28 days did not significantly differ between formulations, thereby supporting the day BUD.
Lidocaine was more stable under acidic conditions and tended to degrade under alkaline conditions. The cleavage of lidocaine in aggressive alkaline conditions yields 2,6-dimethylaniline.
In contrast, the decrease in concentration achieved in the specificity experiments is expected to occur in mildly alkaline conditions. These ingredients likely contribute to the decreased chemical stability over time, despite the relatively constant pH during the course of the study. In addition, drug loss attributed to adsorption to the syringes may account for the decrease in lidocaine concentration in the samples for both mouthwashes and the control product as well as the increase in RSD difference between samples over the course of the study.
The package insert for viscous lidocaine indicates to apply the drug to the oral cavity, swish the undiluted medication around the mouth, and then spit it out. The solution can be gargled and then swallowed as a onetime application when used for pharyngeal anesthesia. Studies evaluating lidocaine-containing mouthwashes are limited in size, formulation, and design. A randomized, blinded trial of 18 patients compared 3 mouthwashes lidocaine plus cocaine; dyclonine; and kaolin plus pectin, diphenhydramine, and 0.
However, the study used a nonvalidated questionnaire for treatment response and a mouthwash that is rarely used. Another study enrolled patients and compared a mouthwash containing lidocaine, diphenhydramine, and Maalox to salt and soda mouthwash 1 teaspoon each of sodium chloride and sodium bicarbonate per pint of water or chlorhexidine using a patient self-assessment tool.
Two randomized trials compared morphine mouthwash with magic mouthwash that contained viscous lidocaine, diphenhydramine, and magnesium hydroxide-aluminum hydroxide-simethicone. The comparative efficacy studies noted here, however, were small and did not include a placebo group.
A Cochrane review found insufficient evidence to support the efficacy of magic mouthwash for the treatment of CIOM. It is also important to note that toxicity after ingestion is not limited to pediatrics, as case reports of lidocaine toxicity in adults also exist, notably in patients with reduced metabolism.
The utility of unit-dose syringes may increase efficiency in pharmacy operations.
Products can be individually drawn up, barcoded, and loaded into automated dispensing cabinets. This allows for quicker delivery to the patient, bedside barcode scanning, and easier inventory management. This also reduces waste as patients prescribed the single product can be dispensed the prescribed number of doses rather than a bulk bottle.
Unused unit-dosed syringes can be returned to stock if acceptable conditions are met. Based on the stability data, published safety concerns, and lack of efficacy in combination, we recommend packaging and dispensing lidocaine separately from other ingredients when administering magic mouthwash mixtures.
With the day BUD, lidocaine can be packaged separately from other magic mouthwash ingredients in individual dosage units and applied to the oral cavity using the swish-and-spit method. The delivery of the diphenhydramine and aluminum hydroxide-magnesium hydroxide-simethicone can be separated, allowing for a swish-and-swallow method of administration.

Stockpiling drugs, vaccines, and medical products is critical to ensure public health emergency preparedness for both the U. To avoid the need to replace entire stockpiles every few years at significant expense, and because it was recognized through testing that certain products remained stable beyond their labeled expiration dates when properly stored, the Shelf-Life Extension Program SLEP was established in SLEP is the federal, fee-for-service program through which the labeled shelf life of certain federally stockpiled medical materiel e.
The program is administered by the U. Department of Defense DoD.
Through expiration dating extensions, SLEP helps to defer the replacement costs of certain products in critical federal stockpiles. Program participants are U. Current testing focuses on military-significant or contingency use products, drugs that have limited commercial use e. In addition to SLEP, there are other ways that, when appropriate, FDA can allow certain medical products to be used beyond their manufacturer-labeled expiration dates.
This authority is limited to medical products for CBRN emergencies. In addition to the identification of specific lots, batches, or other units covered and the duration of the extension, FDA can require appropriate conditions related to any extensions under this authority, including appropriate storage, sampling, recordkeeping, periodic testing or retesting, product disposition, and labeling.
If appropriate, FDA can also choose to not take enforcement action with respect to products that are held or used beyond their labeled expiration date. FDA acknowledges the stockpiling challenges of federal and SLTT stakeholders for example, related to doxycycline, ciprofloxacin, Tamiflu, and certain auto-injector products and remains committed to finding appropriate solutions to address such challenges.
To confirm extension dates, please provide the following information: drug name, NDC, strength, lot number and original manufacture date.
The letter noted that, based on FDA-approved supplemental New Drug Applications for Relenza inhalation powder and Tamiflu capsules that provided an expiration dating period of 7 years, it would be scientifically supportable for the expiry extension i.
