Conclusion In conclusion, Gabapentin oral solution does not need to be refrigerated. Proper storage of this medication at room temperature is sufficient to maintain its stability and effectiveness. Refrigeration can actually be harmful to the medication and compromise its potency. The liquid formulation of gabapentin is typically mixed with syrup or other liquid substances to make it easier to consume, especially for children or individuals with swallowing difficulties. Stability and Shelf Life Unlike the tablet or capsule formulations, liquid gabapentin requires refrigeration. When liquid gabapentin is left at room temperature for an extended period, several factors can influence its safety and efficacy. The stability of the medication can be compromised, potentially leading to reduced effectiveness. Liquid gabapentin is a medication frequently prescribed for managing nerve pain and seizures, and proper storage is essential to maintain its stability. Many patients and caregivers wonder if gabapentin oral solution need to be refrigerated. Refrigeration requirements are determined by the specific formulation and manufacturer guidelines. Understanding the storage conditions is important to DESCRIPTION Neurontin® (gabapentin) Capsules, Neurontin (gabapentin) Tablets, and Neurontin (gabapentin) Oral Solution are supplied as imprinted hard shell capsules containing 100 mg, 300 mg, and 400 mg of gabapentin, elliptical film-coated tablets containing 600 mg and 800 mg of gabapentin or an oral solution containing 250 mg/5 mL of gabapentin. Room temperature storage refers to keeping the medication in an environment that ranges from 68°F to 77°F (20°C to 25°C). This temperature range is ideal for preserving the chemical stability of many medications, including gabapentin. Understanding how long gabapentin liquid can remain effective at room temperature after opening is vital for both patients and caregivers. Storage temperature also need to be evaluated; as stability of compounded preparations is usually evaluated under a shorter period of time (3 months) compared to commercial preparations (2 to 5 years), storage for 3 months at controlled room temperature should also be considered in the stability protocol. Here are key factors that can affect gabapentin’s stability: Temperature: Gabapentin should ideally be stored at controlled room temperatures. Exposing it to excessive heat or cold can hasten its degradation process. Moisture: High humidity levels can negatively impact the formulation, leading to a reduction in its effectiveness. Gabapentin Oral Solution Stability at Room Temperature Gabapentin oral solution is stable at room temperature for up to 24 hours, according to the American Society of Health-System Pharmacists. After this time frame, it begins to degrade and should be discarded and replaced with a fresh dose. It is important that Gabapentin oral solution not be stored above 25°C (77°F). Liquid Gabapentin Not Our study is thus clinically useful as it reports a stable gabapentin liquid preparation in easy-to-work-with and globally available vehicles that can be stored at room temperature. The pH of the solutions ranged from 3.50 to 3.77 during the study. Gabapentin (C9H17NO2, MW 171.24) occurs as white to off-white, crystalline solid that is freely soluble in water. Gabapentin 100 mg/mL oral suspension was prepared using a 1:1 mixture of ORA-Plus®/ORA-Sweet® and stored at both room and refrigerated temperatures. The solution stability of gabapentin in buffered systems was studied in order to facilitate the formulation of a liquid product. The degradation of the drug was followed as a function of pH, buffer concentration, ionic strength, and temperature. Reference: 1. Friciu M, Roullin VG, Leclair G. Stability of gabapentin in extemporaneously compounded oral suspensions. PLoS ONE. 2017; 12(4): 1-11. The objective of this study was to determine the stability of gabapentin in SyrSpend SF, a suspending agent that does not contain either sorbitol or alcohol. The studied samples were compounded into a 50-mg/mL suspension and stored in low actinic bottles at room temperature and refrigerated conditions. Technician Training Tutorial: Handling Refrigerated Drugs and Vaccines Several medications and vaccines require refrigeration while stored in the pharmacy and/or after being dispensed to the patient. Inadvertent storage of refrigerated medications at room temperature causes accelerated drug or chemical breakdown resulting in reduced shelf-life or total loss of effectiveness. Rarely, the Stability of Gabapentin Liquid Stability refers to the ability of a medication to maintain its safety and efficacy over time, under specified conditions. Gabapentin liquid typically retains its effectiveness when stored at room temperature, but it can degrade due to various factors. Gabapentin is available as oral capsules of 100 mg, 300 mg, and 400 mg; tablets of 100 mg, 300 mg, 400 mg, 600 mg, and 800 mg; and an oral solution of 50 mg/mL. However, the need often exists for a higher-concentration oral liquid, and if tablets or capsules are used as the drug source, a suspension will result. This study reports the stability of extemporaneously prepared gabapentin oral suspensions prepared at 100 mg/mL from bulk drug and capsules in either Oral Mix or Oral Mix SF suspending vehicles. The objective of this study was therefore to unequivocally evaluate the stability of compounded liquid preparations of gabapentin in refrigerated conditions, as well as to study the stability of this compound in a pediatric vehicle readily available in Canada. We applied the generally-agreed definition of stability as previously described. The active ingredient, gabapentin, is inherently sensitive to temperature fluctuations, and the excipients (inactive ingredients) in the liquid formulation can further degrade its stability if not stored properly.
