Introduction
Amikacin Sulphate Injection 500 mg is a powerful antibiotic medication used to treat severe bacterial infections. It belongs to the aminoglycoside class of antibiotics and works by stopping the growth of harmful bacteria in the body. This medicine is usually given by a healthcare professional through injection, making it suitable for treating serious infections that cannot be effectively managed with oral antibiotics.
Amikacin is often prescribed for infections affecting the lungs, urinary tract, bones, joints, abdomen, and bloodstream, as well as for patients who do not respond to other antibiotics.
Uses of Amikacin Sulphate Injection 500 mg
Amikacin Sulphate Injection is primarily used to treat bacterial infections caused by gram-negative organisms and some gram-positive bacteria. Common medical conditions treated include:
- Respiratory tract infections (such as pneumonia and bronchitis)
- Urinary tract infections (UTIs)
- Skin and soft tissue infections, Intra-abdominal infections
- Bone and joint infections
- Bloodstream infections (septicemia)
- Meningitis (inflammation of the brain and spinal cord membranes)
- Post-surgical infections
Doctors may also prescribe this medicine in combination with other antibiotics for more effective results in complex infections.
Ingredients of Amikacin Sulphate Injection 500 mg
The primary active ingredient is: Amikacin Sulphate (500 mg)
How Amikacin Sulphate Injection 500 mg Works
Amikacin works by inhibiting bacterial protein synthesis, a process necessary for bacteria to grow and multiply. Specifically, it binds to the 30S ribosomal subunit of the bacterial cell, preventing the formation of essential proteins. This results in bacterial cell death and the eventual elimination of infection.
Because of this mechanism, Amikacin is highly effective against a wide range of gram-negative bacteria and some resistant strains that are not responsive to other antibiotics.
Dosage of Amikacin Sulphate Injection 500 mg
The dosage and duration of treatment depend on several factors, including the type and severity of infection, age, weight, and kidney function of the patient.
- General Dosage Guidelines: Adults: Usually, 15 mg/kg per day, divided into two equal doses every 12 hours.
- Children: 15–20 mg/kg per day, given in divided doses.
- Neonates (newborns): An initial dose of 10 mg/kg, followed by 7.5 mg/kg every 12 hours.
