Stability: A beyond-use date of up to 56 days at room temperature or 91 days at refrigerated temperature may be used for this preparation. 1,2 As crystallization was observed at 5°C, storage at this temperature condition is not recommended. All preparations stored at 25°C / 60%RH remained stable for the whole study duration of 90 days. This study was supported by an unrestricted grant from Medisca Pharmaceutique Inc. Gabapentin is a gamma-aminobutyric acid analogue, which has been shown to be an effective antiepileptic. 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. According to the medication’s prescribing information, Gabapentin oral solution should be stored at room temperature, between 68°F and 77°F (20°C and 25°C). It is important to note that this medication does not require refrigeration. 400 mg oral doses of gabapentin. The mean gabapentin half-life ranged from about 6.5 hours (patients with creatinine clearance >60 mL/min) to 52 hours (creatinine clearance <30 mL/min) and Room Temperature: It is generally advised to store gabapentin liquid at room temperature (between 15°C to 30°C), unless stated otherwise by the manufacturer. Tightly Sealed: Ensure the bottle is tightly closed when not in use to prevent contamination. Avoid Bathrooms: Avoid storing medication in the bathroom, where humidity can fluctuate In 2012, Sorenson reported that gabapentin 50 mg/mL in SyrSpend SF conditioned in low actinic bottles was stable at least 90 days when refrigerated or stored at room temperature [18]. In 2014, Soliman tested the stability of gabapentin 100 mg/mL suspension in a methylcellulose vehicle after three months of refrigeration. Gabapentin is stable at room temperature, but if it’s been improperly stored, its efficacy may decline. Always check for any unusual changes in color or texture before use. If in doubt, consult a pharmacist for guidance. Do not stop taking Gabapentin Oral Solution without first talking to your healthcare provider. Stopping Gabapentin Oral Solution suddenly can cause serious problems. Gabapentin Oral Solution can cause serious side effects including: 1. Like other antiepileptic drugs, Gabapentin Oral Solution may cause suicidal thoughts or actions Transfer to a 250 mL amber bottle (to allow for adequate shaking of suspension) and label. Opaque off-white suspension. At room temperature the product can change colour to a light brown/yellow. 1. Friciu M, Roullin VG, Leclair G. Stability of gabapentin in extemporaneously compounded oral suspensions. PLoS ONE. 2017; 12(4): 1-11. Gabapentin is not available in a liquid dosage form for clinical use. This study was designed to develop two oral gabapentin suspensions and determine their stability under refrigeration or at room temperature. when maintained at room temperature for up to 6 months. 9 Schering Corporation 800-222-7579 Gabapentin oral suspension (Neurontin) Refrigerate at 36º to 46º F (2º to 8ºC). Contact manufacturer.*** Off-label § information indicates oral solution stable for seven days at temps up to 86 o F (30 o C). 6 Pfizer 800-438-1935 Glatiramer acetate It is not advisable to leave liquid gabapentin at room temperature for an extended period, as it may lead to decreased potency and potential bacterial growth. Practice rePorts storage of medications 1714 Am J Health-Syst Pharm—Vol 64 Aug 15, 2007 Palivizumab powder and solution Pancuronium bromide injection Peg-interferon alfa-2a vial Peg-interferon alfa-2a vial prefilled syringe Penicillin G benzathine injection suspension Penicillin G benzathine and penicillin G procaine injection suspension Pneumococcal 7-valent conjugate vaccine (diphtheria CRM 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. Stopping gabapentin oral solution suddenly can cause serious problems. Gabapentin oral solution can cause serious side effects including: 1. Suicidal Thoughts. Like other antiepileptic drugs, gabapentin oral solution may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. 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. 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. Suspensions were packaged in amber plastic bottles and amber plastic syringes at 25°C / 60%RH for up to 90 days. Throughout the study period, the following tests were performed to evaluate the We studied the effect of the following variables: (1) time: up to 90 days; (2) temperature: 25°C; (3) gabapentin source: bulk drug and capsules; (4) vehicle: Oral Mix and Oral Mix SF; and (5) packaging: amber PET bottles and oral plastic syringes. This study was designed to develop two oral gabapentin suspensions and determine their stability under refrigeration or at room temperature. Commercially available gabapentin capsules were used to prepare two suspensions: one in extemporaneously prepared 1% methylcellulose in syrup (1:1) and another in equal volumes of commercially available
