PURPOSE To study the physical compatibility of ibuprofen lysine injection (NeoProfen, Ovation Pharmaceuticals Inc., Deerfield, IL) with medications commonly used in the premature neonatal population during simulated Y-site administration. MATERIALS AND METHODS Commonly used intravenous medications in preterm infants were evaluated for physical compatibility with ibuprofen lysine injection. A 20-mL sample of ibuprofen lysine drug product solution was mixed with a 20-mL sample of each of the 34 medications at concentrations used clinically. The mixtures were stored at room temperature and each sample was evaluated for turbidity and physical appearance at time 0 (immediately after preparation) and at 4 hours after preparation. RESULTS The following drugs were deemed compatible with ibuprofen lysine: ceftazidime, epinephrine, furosemide, heparin lock flush, diluted insulin, morphine sulfate, phenobarbital, potassium chloride, and sodium bicarbonate. Diluted dopamine was initially compatible at time 0 but showed a small precipitate at the 4-hour time point. CONCLUSION Of the 37 drug solutions tested, 14 preparations (10 medications; several with more than one diluent) showed physical compatibility with ibuprofen lysine, 1 was compatible at time 0 and incompatible at 4 hours, and 1 could not be evaluated. The remaining preparations were considered to be incompatible.

Introduction: Impacted cerumen is a widespread reason that patients visit their health care providers. It effects approximately 2-6% of the general population and disproportionately impacts up to 65% of patients over 65. This study compared a new cerumen (earwax) removal product (Solution 1; EOS-002; a glycolic acid/bicarbonate formulation) versus two commercially available products (Solution 2 and Solution 3; both containing carbamide peroxide 6.5%) for their cerumenolytic activity in vitro. Methods: Samples of human cerumen were placed in 10 x 75 mm polypropylene test tubes. Approximately 1 mL of each test solution was added and incubated at room temperature for 30 minutes. The vials were shaken at the 15- and 30-minute time points to simulate rinsing in a clinical setting. Breakdown of the cerumen was graded at 5-, 10-, 15-, and 30-minute time points in a masked manner on a 5-point scale (Grade 0 = no change; Grade 4 = complete disintegration). Results: Significantly greater disintegration of the cerumen was observed in the samples exposed to EOS-002 at every time point (P < 0.0001). At 5 minutes, disintegration was observed in 39 out of 43 samples exposed to EOS-002, 0 out of 24 samples exposed to Solution 2, and 1 out of 19 samples exposed to Solution 3. Mean disintegration scores at 5, 10, 15, and 30 minutes were 1.65, 2.38, 2.95, and 3.24 for EOS-002; 0, 0, 0, and 0.2 for Solution 2; and 0.05, 0.13, 0.16, and 0.21 for Solution 3, respectively. Discussion: EOS-002 exhibited a significantly greater ability to breakdown cerumen than the two other products. Disintegration of cerumen occurred with EOS-002 within 5 minutes in 91% (39/43) of the samples. Therefore, EOS-002 provides rapid disintegration of human cerumen in vitro.

OBJECTIVE The purpose of this study was to examine the stability of a generic lansoprazole product in a 3 mg/mL sodium bicarbonate suspension under room temperature and refrigerated conditions. METHODS Lansoprazole suspensions (3 mg/mL) were prepared in triplicate using an 8.4% sodium bicarbonate vehicle for each storage condition (room temperature and refrigerated). During 1 month, samples from each replicate were periodically removed and analyzed for lansoprazole concentration by liquid chromatography–tandem mass spectrometry (LC-MS/MS). Each sample was spiked with 10 mg/L omeprazole to serve as the internal standard. A positive electrospray LC-MS/MS method was validated over the calibration range of 5 to 25 mg/L using Food and Drug Administration Guidance. The identities of the analyte and internal standard in the samples were verified by monitoring the MS/MS transitions of m/z 370 to m/z 252 and m/z 346 to m/z 198 for lansoprazole and omeprazole, respectively. Additionally, the pH of the suspensions was monitored throughout the study. RESULTS The stability of lansoprazole in the oral sodium bicarbonate suspension under refrigeration is compromised prior to what has been previously reported in the literature. Samples kept at room temperature lost &gt;10% of the lansoprazole after 48 hours compared with the refrigerated samples, which maintained integrity up to 7 days. No statistically significant difference was found between the pH of the room temperature and refrigerated suspension samples, indicating that this factor is not the cause for the differences in stability at these two conditions. CONCLUSIONS This study suggests that the extemporaneously compounded lansoprazole oral suspension prepared in 8.4% sodium bicarbonate should not be stored in plastic oral syringes longer than 48 hours at room temperature and no longer than 7 days when refrigerated. These data indicate an expiration time earlier than that previously reported for the refrigerated product (14 days).

1. A group of eight patients with mild hypertension, sensitive to sodium intake, were studied. 2. Sodium chloride (70 mmol daily) caused their blood pressure to rise by 19/14 mmHg. 3. Sodium bicarbonate (70 mmol daily) caused their blood pressure to rise by 12/5 mmHg. 4. Sodium chloride given together with potassium chloride (70 mmol of each daily) caused their blood pressure to rise by 9.6 mmHg. 5. These results suggest that sodium bicarbonate causes a smaller rise in blood pressure than sodium chloride does and that potassium chloride reduces the blood pressure raising effect of sodium chloride. 6. A low sodium, high potassium and an alkaline diet may therefore be a more effective dietary method to reduce blood pressure than a diet low in sodium alone.
