IRRIGATING SOLUTION G IN PLASTIC CONTAINER
Clinical safety rating: caution
Comprehensive clinical and safety monograph for IRRIGATING SOLUTION G IN PLASTIC CONTAINER (IRRIGATING SOLUTION G IN PLASTIC CONTAINER).
Irrigating solution G is a sterile, non-pyrogenic, isotonic solution used for irrigation during urological procedures. It contains glycine, which is an amino acid that does not conduct electricity, making it suitable for use with electrosurgical instruments. The solution helps maintain a clear surgical field and prevents hemolysis.
| Metabolism | Glycine is metabolized via the glycine cleavage system and also converted to serine, which enters the gluconeogenesis pathway. It is also oxidized to carbon dioxide and water. |
| Excretion | Renal: >95% as unchanged drug; fecal/biliary: negligible |
| Half-life | Approximately 30 minutes; indicates rapid renal clearance |
| Protein binding | <1% (primarily albumin) |
| Volume of Distribution | 0.5-0.6 L/kg; limited to extracellular fluid |
| Bioavailability | Intravenous: 100%; oral: not applicable |
| Onset of Action | Intravenous: immediate; irrigation: within minutes |
| Duration of Action | 15-30 minutes after irrigation; sustained only with continuous administration |
Not applicable; irrigating solution G is used topically during surgery.
| Dosage form | SOLUTION |
| Renal impairment | No dose adjustment required; negligible systemic absorption. |
| Liver impairment | No dose adjustment required; negligible systemic absorption. |
| Pediatric use | Dose as per surgical irrigation needs; no specific weight-based guidelines. |
| Geriatric use | No specific considerations; use same as adult. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |
| 3rd trimester | Consult provider |
Clinical note

None.
| Serious Effects |
["Hypersensitivity to glycine or any component of the solution.","Preexisting severe electrolyte imbalances or hyperglycemia.","Use for intravenous infusion or as a transport solution for medications."]
| Precautions | ["Risk of fluid overload and electrolyte disturbances, especially in patients with renal impairment or heart failure.","Hypotonic solutions may cause hemolysis; use of proper solution is essential.","Monitor for signs of glycine toxicity (e.g., visual disturbances, confusion, hypotension) during prolonged procedures.","Use with caution in patients with hepatic impairment due to potential ammonia accumulation."] |
