AMUROX 500 TABLETS

Indications

• Anxiety disorders
• Epilepsy
• Neuropathic pain
• Sleep disorders
• Neurodegenerative diseases

Dosage

Children: Refer to the BNF for Children for appropriate dosing information based on age and weight.

Adults: Refer to the prescribing information for specific dosing guidelines based on the condition being treated and patient characteristics.

Mechanism of action

Axetol is thought to act through the modulation of neurotransmitter systems, particularly by enhancing the activity of inhibitory neurotransmitters such as gamma-aminobutyric acid (GABA). This action can lead to a reduction in neuronal excitability and a subsequent neuroprotective effect, making it beneficial in conditions characterized by excessive neuronal activity.

Pharmacodynamics

The pharmacodynamic effects of Axetol include its ability to stabilize neuronal membranes and reduce oxidative stress, which can contribute to neurodegeneration. Additionally, its anxiolytic and sedative properties may help in managing anxiety and sleep disturbances associated with neurological disorders.

Pharmacokinetics

Axetol is absorbed following oral administration, with peak plasma concentrations occurring within a few hours. It is metabolized primarily in the liver, with a half-life that may vary based on individual patient factors, including age and liver function. Excretion is primarily via the kidneys, and it is important to monitor renal function during therapy.

Pregnancy

The safety of axetol during pregnancy has not been established. Use only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

It is unknown whether axetol is excreted in human milk. Caution is advised when administering to breastfeeding women.

Storage

Store at room temperature, away from light and moisture. Keep out of reach of children.

Indications

• Community-acquired pneumonia
• Urinary tract infections
• Skin and soft tissue infections
• Intra-abdominal infections
• Bacteremia
• Bone and joint infections

Dosage

Children: Refer to the BNF for Children for appropriate dosing guidelines in paediatric populations.

Adults: Refer to the BNF for specific dosing information as it may vary based on the infection being treated and patient factors.

Mechanism of action

Efuroxine exerts its antibacterial effect by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the transpeptidation reaction crucial for cross-linking peptidoglycan layers, which are essential for maintaining cell wall integrity. As a result, the bacterial cell wall becomes weakened, leading to cell lysis and death.

Pharmacodynamics

The pharmacodynamic properties of efuroxine include its ability to exhibit time-dependent killing, where the duration of time the drug concentration remains above the minimum inhibitory concentration (MIC) is critical for its efficacy. Efuroxine demonstrates a broad spectrum of activity against various pathogens, including Streptococcus pneumoniae, Escherichia coli, and Haemophilus influenzae, among others. Resistance mechanisms can include the production of beta-lactamases and alterations in PBPs.

Pharmacokinetics

Efuroxine is administered via the parenteral route, with bioavailability depending on the specific formulation used. It is widely distributed throughout the body and can penetrate various tissues, including the central nervous system, albeit to a limited extent. The drug is primarily excreted through the kidneys, with renal clearance being a significant route of elimination. Dosage adjustments may be necessary in patients with renal impairment to avoid accumulation and toxicity.

Adverse effects

• Nausea
• Diarrhea
• Abdominal pain
• Headache
• Rash
• Allergic reactions

Interactions

• May interact with other antibiotics
• Potential interaction with anticoagulants
• May affect the efficacy of oral contraceptives

Precautions

• Use with caution in patients with a history of allergic reactions to beta-lactam antibiotics
• Monitor renal function in patients with renal impairment
• Consider potential for Clostridium difficile-associated diarrhea

Pregnancy

Consult healthcare provider. Use only if clearly needed as safety in pregnancy has not been established.

Breast-feeding

Use with caution, as it is not known whether efuroxine is excreted in human milk.

Storage

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Formulations
