Product Description
Ampicillin Vial 250mg is a widely used antibiotic that belongs to the penicillin class. It is effective against a range of bacterial infections, particularly those caused by susceptible strains of gram-positive and some gram-negative bacteria. This specific vial contains 250mg of ampicillin, ready to be reconstituted and administered intravenously or intramuscularly.
How Ampicillin Works:
Ampicillin works by interfering with the synthesis of peptidoglycans, which are essential components of bacterial cell walls. This disruption weakens the bacterial cell wall, leading to cell lysis and bacterial death.
Uses of Ampicillin Vial 250mg:
Ampicillin is commonly used to treat infections in various parts of the body, including:
- Respiratory Infections: Pneumonia, bronchitis, and sinusitis caused by susceptible bacteria.
- Urinary Tract Infections (UTIs): Cystitis and pyelonephritis caused by susceptible bacteria.
- Skin and Soft Tissue Infections: Cellulitis, erysipelas, and wound infections.
- Meningitis: Bacterial meningitis caused by susceptible bacteria.
- Gastrointestinal Infections: Infections caused by Salmonella and Shigella.
- Endocarditis: Bacterial endocarditis caused by susceptible bacteria.
- Septicemia: Bloodstream infections caused by susceptible bacteria.
Dosage and Administration:
- Intravenous (IV) or Intramuscular (IM) Administration: Ampicillin Vial 250mg is typically administered intravenously or intramuscularly.
- Reconstitution: The vial contents must be reconstituted with a sterile diluent before administration. The specific diluent and reconstitution instructions will be provided with the vial.
- Dosage Calculation: Dosage is highly individualized based on the patient's condition, age, weight, and response to treatment.
- Adults: The recommended dosage for most infections is 1-2 grams every 4-6 hours.
- Children: Dosage for children is calculated based on their weight and the specific infection being treated.
Important Precautions:
- Hypersensitivity: Ampicillin is contraindicated in patients with known hypersensitivity to penicillin antibiotics.
- Allergic Reactions: Serious and occasionally fatal hypersensitivity reactions have been reported with ampicillin.
- Severe Skin Reactions: Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported with ampicillin.
- Gastrointestinal Side Effects: Ampicillin can cause gastrointestinal side effects, including diarrhea, nausea, vomiting, and abdominal pain. In severe cases, it can lead to antibiotic-associated colitis, a potentially life-threatening condition caused by an overgrowth of Clostridium difficile bacteria.
- Renal Impairment: Ampicillin is primarily excreted by the kidneys. In patients with renal impairment, the dosage should be reduced to compensate for slower excretion.
- Concurrent Medications: Ampicillin should be used with caution in patients receiving concurrent treatment with potent diuretics (such as furosemide) or aminoglycosides.
Side Effects:
Common side effects include:
- Gastrointestinal: Diarrhea, nausea, vomiting, abdominal pain.
- Skin: Rash, itching, hives.
- Injection Site: Pain, redness, swelling at the injection site.
Less common, but more serious side effects can include:
- Antibiotic-associated colitis: Severe diarrhea, abdominal cramps, fever, and bloody stools.
- Hypersensitivity reactions: Anaphylaxis, angioedema, Stevens-Johnson syndrome, toxic epidermal necrolysis.
- Kidney problems: Change in the amount of urine, blood in the urine.
- Liver problems: Nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine.
Drug Interactions:
Ampicillin can interact with other medications, including:
- Neuromuscular blocking agents: Ampicillin can enhance the effects of neuromuscular blocking agents.
- Vitamin K antagonists: Ampicillin can increase the risk of bleeding when taken with vitamin K antagonists like warfarin.
- Probenecid: Probenecid can increase the levels of ampicillin in the blood.
