Description
Grasil injection is a brand form of amikacin (an aminoglycoside antibiotic). It is used to treat serious bacterial infections caused by organisms susceptible to amikacin. The 1 ml ampoule delivers 25 mg of amikacin. The injectable formulation ensures rapid and direct systemic availability.
Ingredients
-
Active ingredient: Amikacin sulfate equivalent to 25 mg per 1 ml ampoule
-
Excipients / inactives: Water for injection, stabilizers, buffers, etc. (as per manufacturer)
Drug Class
Aminoglycoside antibiotic (bactericidal, concentration-dependent)
Dosage Form
Sterile injectable solution — 1 ml ampoule containing 25 mg amikacin
Uses (Indications)
Grasil (amikacin) is indicated for serious infections caused by Gram-negative bacteria or those resistant to other antibiotics, such as:
-
Bacteremia / sepsis
-
Lower respiratory tract infections
-
Intra-abdominal infections
-
Urinary tract infections
-
Bone and joint infections
-
Skin & soft tissue infections
-
Postoperative infections
-
Others where a potent aminoglycoside is needed
Dosage
-
The dose for amikacin is typically calculated based on patient weight and renal function.
-
A commonly used regimen is 15 mg/kg per day, divided into multiple doses or sometimes once daily, depending on severity and pharmacokinetics.
-
In your product case (25 mg per 1 ml ampoule), multiple ampoules might be used to reach the needed dose depending on weight, under medical guidance.
-
Dose adjustments in renal impairment are critical.
In Case of Overdose
-
Potential symptoms: hearing damage (ototoxicity), kidney damage (nephrotoxicity), neuromuscular blockade (weakness), vestibular toxicity (dizziness)
-
Treatment: supportive care, stopping the drug, monitoring kidney function, hearing tests, hydration, monitoring of electrolytes.
Missed Dose
-
In clinical settings, missing a dose must be evaluated by the treating physician.
-
Do not double up the next dose to compensate.
How To Use / Administration
-
Administer intravenous (IV) or intramuscular (IM) routes.
-
For IV, infusion over 30–60 minutes is common to reduce toxicity risk.
-
Use aseptic technique.
-
Monitor patient during and after administration (renal function, hearing, balance, vital signs).
When Not to Use (Contraindications)
-
Known hypersensitivity or allergic reaction to amikacin or aminoglycosides
-
Pre-existing hearing loss or vestibular dysfunction
-
Severe renal impairment (unless dose adjustment)
-
Myasthenia gravis or neuromuscular diseases (risk of neuromuscular blockade)
-
Pregnancy and lactation: use only if benefits outweigh risks (aminoglycosides can cross placenta)
-
Use with caution in the elderly
Side Effects
Common / less serious:
Serious / toxic:
-
Ototoxicity (hearing loss, tinnitus, vestibular damage)
-
Nephrotoxicity (renal damage)
-
Neuromuscular blockade, especially in susceptible individuals
-
Allergic reactions (rash, anaphylaxis)
Precautions & Warnings
-
Regularly monitor renal function (serum creatinine, BUN)
-
Monitor auditory and vestibular function (hearing tests)
-
Hydration is important to reduce nephrotoxicity
-
Avoid use with other nephrotoxic or ototoxic drugs
-
Use the lowest effective dose for shortest duration
-
Inform surgical / dental teams of amikacin use
Drug Interactions
-
Concurrent use of other nephrotoxic agents (e.g., aminoglycosides, vancomycin, cisplatin, loop diuretics) increases kidney risk
-
Other ototoxic drugs (e.g., loop diuretics) may add hearing risk
-
Neuromuscular blocking agents (e.g., suxamethonium, tubocurarine) may have additive effects on muscle weakness
Storage / Disposal
-
Store at controlled room temperature, below recommended maximum (often ≤ 25–30 °C)
-
Protect from light, moisture
-
Do not freeze
-
Use before expiry
-
Dispose unused/expired ampoules safely as medical waste
Control Drug Status
Quick Tips
-
Always adjust dose for renal function
-
Use slow infusion to minimize toxicity
-
Monitor hearing and kidney parameters during therapy
-
Avoid combining with other harmful drugs
-
Use minimal effective duration
-
Inform patients of signs of hearing loss or dizziness
