🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAfter deep intramuscular injection, penicillin G is absorbed slowly from the injection site due to the presence of procaine, which forms a poorly soluble salt. Peak plasma concentrations are typically achieved within 1 to 4 hours. The absorption rate is influenced by the injection site and blood flow.
DistributionPenicillin G distributes widely into body tissues and fluids, including the lungs, liver, kidneys, and synovial fluid. It penetrates the cerebrospinal fluid poorly unless the meninges are inflamed. It crosses the placenta and is excreted in breast milk.
Protein BindingPenicillin G is approximately 60% bound to plasma proteins, primarily albumin.
MetabolismPenicillin G is metabolized to a limited extent in the liver, with about 10-20% undergoing hepatic metabolism to inactive metabolites.
Half-LifeThe elimination half-life of penicillin G from procaine penicillin is approximately 30 to 60 minutes, but the prolonged absorption from the injection site results in detectable blood levels for up to 24 hours.
ExcretionPenicillin G is primarily excreted unchanged by the kidneys via tubular secretion and glomerular filtration. About 60-90% of a dose is excreted in the urine within 24 hours.
BioavailabilityBioavailability is not applicable for intramuscular injection as it is directly administered into the muscle. The systemic availability is high but depends on absorption from the injection site.
Onset of ActionThe onset of action is typically within 1 to 2 hours after intramuscular injection, with peak effects occurring as the drug is absorbed.
Peak Plasma TimePeak plasma concentrations are usually reached within 1 to 4 hours after intramuscular administration.
Duration of ActionThe duration of action is approximately 24 hours, allowing for once-daily dosing in many indications.

How It Works

This medicine works by inhibiting the final step of bacterial cell wall synthesis. The active ingredient, penicillin G, binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the transpeptidation reaction that cross-links peptidoglycan chains, which are essential for cell wall strength and rigidity. As a result, the bacterial cell wall becomes weakened, leading to cell lysis and death, especially in actively dividing bacteria. Procaine is added to prolong the absorption of penicillin G from the injection site, providing sustained low levels of the antibiotic in the bloodstream.

Mechanism Steps

1
Binding to penicillin-binding proteins: Penicillin G binds irreversibly to penicillin-binding proteins (PBPs) on the bacterial cell membrane.
2
Inhibition of transpeptidation: This binding inhibits the transpeptidase enzyme responsible for cross-linking peptidoglycan strands in the bacterial cell wall.
3
Weakening of cell wall: Without cross-linking, the cell wall becomes structurally weak and unable to withstand osmotic pressure.
4
Cell lysis and death: The bacterial cell swells and bursts due to osmotic imbalance, leading to bacterial death.
5
Prolonged action by procaine: Procaine slows the absorption of penicillin G from the intramuscular depot, extending its duration of action.

Dosage Information

Adult DosageThe dosage of this medicine is individualized by a qualified clinician based on the indication, severity of infection, and patient factors. For most adult infections, a common dose is 600,000 to 2,400,000 IU once daily or every other day by deep intramuscular injection. For syphilis, the dose may be 2,400,000 IU once daily for 10 to 14 days. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children.
Elderly DosageElderly patients may have reduced renal function, which can increase the risk of toxicity. Dose adjustment may be necessary based on renal function. Use with caution and monitor closely.
Renal ImpairmentIn patients with renal impairment, the dose or frequency may need to be reduced. For creatinine clearance less than 10 mL/min, the dose may need to be adjusted. Consult a clinician for specific recommendations.
Hepatic ImpairmentNo specific dosage adjustments are established for hepatic impairment. Use with caution and monitor liver function.
Maximum Daily DoseThe maximum daily dose is not established from available information. Dosing must be determined by a qualified clinician based on the indication and patient factors.

🤱 Lactation Safety

Penicillin G is excreted in breast milk in low concentrations. It is generally considered safe during breastfeeding, but monitor the infant for diarrhea, thrush, or allergic reactions. Consult a doctor before use.

💊 Overdose Management

Overdose with this medicine is unlikely due to its intramuscular route and limited dosing. However, high doses can cause neurotoxicity, especially in patients with renal impairment. Treatment is symptomatic and supportive. In case of accidental overdose, seek immediate medical attention. Hemodialysis may be considered to remove penicillin from the blood in severe cases.

⏰ Missed Dose

Since this medicine is administered by a healthcare professional, missed doses are unlikely. If you miss a scheduled appointment for your injection, contact your doctor as soon as possible to reschedule. Do not attempt to self-administer. Maintain the prescribed dosing schedule to ensure effective treatment.

Additional Safety Advice

General Safety

This medicine must be given by a healthcare professional as a deep intramuscular injection. Do not attempt to self-administer.
