Ampexin Injection

Introduction

Ampexin Injection 250 mg/vial is a broad-spectrum, beta-lactam antibiotic that belongs to the penicillin class. It is used to treat various bacterial infections. Ampexin Injection 250 mg/vial works by inhibiting bacterial cell wall synthesis, leading to the destruction of the bacteria.

Uses

Ampexin Injection 250 mg/vial is commonly used to treat infections caused by susceptible bacteria, including:

• Respiratory tract infections (e.g., pneumonia, bronchitis).
• Urinary tract infections (e.g., cystitis, pyelonephritis).
• Gastrointestinal infections (e.g., salmonella, shigella).
• Menigitis and endocarditis.

Mechanism of Action

Ampexin Injection 250 mg/vial works by inhibiting the synthesis of bacterial cell walls. It binds to penicillin-binding proteins (PBPs) on the bacterial cell membrane, preventing the cross-linking of peptidoglycan chains, which is essential for bacterial cell wall integrity. This disruption leads to cell lysis and death.

How Long Does It Take to Work?

Clinical improvement is often observed within 1-2 days of starting treatment with ampicillin. However, the duration to full resolution of symptoms can vary based on the severity of the infection and the patient's overall health.

Absorption

Ampexin Injection 250 mg/vial is absorbed from the gastrointestinal tract, with oral administration leading to peak plasma concentrations within 1-2 hours. Food may slightly reduce the absorption of ampicillin, but it is still effective when taken with or without food.

Route of Elimination

Ampexin Injection 250 mg/vial is primarily eliminated through the kidneys. It is excreted in the urine, with a significant portion of the drug being excreted as unchanged ampicillin. Small amounts are also excreted in the bile and feces.

Dosage

The dosage of ampicillin depends on the type and severity of the infection. Typical dosages are:

• Adults: 250-500 mg every 6 hours.
• Severe infections: 1-2 g every 4-6 hours.
• Children: 50-100 mg/kg/day in divided doses.

Dosage adjustments may be necessary for patients with renal impairment.

Administration

Ampexin Injection 250 mg/vial can be administered orally in the form of capsules or liquid suspension, or intravenously for more severe infections. The route of administration depends on the infection type and patient condition.

Side Effects

Common side effects of ampicillin include:

• Nausea, vomiting, and diarrhea.
• Rash and allergic reactions.
• Superinfection (e.g., yeast infections).

Serious side effects may include severe allergic reactions or anaphylaxis.

Toxicity

Toxicity from ampicillin is rare but can occur, especially in cases of overdose. Symptoms may include gastrointestinal disturbances and renal impairment. In severe cases, anaphylactic reactions or seizures may occur.

Precautions

Precautions with ampicillin include:

• Monitor for allergic reactions, especially in patients with a history of penicillin allergy.
• Use with caution in patients with renal impairment or a history of gastrointestinal disease.
• Regular monitoring may be required for patients with prolonged therapy.

Interaction

Ampexin Injection 250 mg/vial may interact with other medications, including:

• Allopurinol: Increases the risk of rash.
• Probenecid: May increase ampicillin levels by reducing renal clearance.

Disease Interaction

Ampexin Injection 250 mg/vial should be used cautiously in patients with:

• Renal disease: Dose adjustment may be needed.
• Gastrointestinal diseases: Such as colitis.

Drug Interaction

Ampexin Injection 250 mg/vial may interact with:

• Oral contraceptives: May reduce their effectiveness.
• Other antibiotics: Such as tetracyclines, which may interfere with the effectiveness of ampicillin.

Food Interactions

Food can affect the absorption of ampicillin. Although it can be taken with or without food, taking it with food may reduce gastrointestinal upset.

Pregnancy Use

Ampexin Injection 250 mg/vial is categorized as a Category B drug for pregnancy. It is generally considered safe to use during pregnancy, but it should be used only when clearly needed. Consult a healthcare provider for personalized advice.

Lactation Use

Ampexin Injection 250 mg/vial is excreted in breast milk in small amounts. It is generally considered safe for use during lactation, but monitoring for potential adverse effects in the infant is advised.

Acute Overdose

In cases of acute overdose, symptoms may include gastrointestinal disturbances and renal issues. Treatment involves supportive care and symptomatic management. Contact a healthcare provider or poison control center immediately.

Contraindication

Ampexin Injection 250 mg/vial is contraindicated in patients with:

• Known hypersensitivity to penicillins or cephalosporins.
• Severe renal impairment, unless dose adjustments are made.

Use Direction

Follow the prescribed dosage and duration of treatment. Do not stop taking ampicillin prematurely, even if symptoms improve, to ensure the infection is fully treated.

Storage Conditions

Store ampicillin at room temperature, away from moisture and heat. Keep it in a tightly closed container, out of reach of children.

Volume of Distribution

The volume of distribution of ampicillin is approximately 0.2 to 0.3 L/kg in adults. It is distributed widely throughout body tissues and fluids.

Half Life

The half-life of ampicillin is approximately 1 to 1.5 hours. It may be prolonged in cases of renal impairment.

Clearance

The clearance of ampicillin is primarily through the kidneys. Renal clearance accounts for the majority of the drug's elimination from the body, with adjustments needed in patients with renal impairment.
