🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCefaclor is rapidly absorbed from the gastrointestinal tract after oral administration. The presence of food may delay absorption slightly but does not significantly reduce the overall extent of absorption. Peak plasma concentrations are typically achieved within 30 to 60 minutes after dosing.
DistributionCefaclor is widely distributed into body tissues and fluids, including the pleural fluid, synovial fluid, and peritoneal fluid. It crosses the placenta and is excreted in breast milk in small amounts. It does not penetrate the cerebrospinal fluid well in the absence of inflammation.
Protein BindingApproximately 25% of cefaclor is bound to plasma proteins.
MetabolismCefaclor is not significantly metabolized in the body. It is primarily excreted unchanged.
Half-LifeThe elimination half-life of cefaclor in healthy adults with normal renal function is approximately 0.6 to 0.9 hours.
ExcretionCefaclor is excreted primarily unchanged in the urine by glomerular filtration and tubular secretion. About 60% to 85% of a dose is recovered in the urine within 8 hours.
BioavailabilityThe oral bioavailability of cefaclor is approximately 50% to 60% when taken on an empty stomach, but it may be slightly reduced when taken with food.
Onset of ActionThe onset of antibacterial action begins shortly after absorption, typically within 1 to 2 hours after oral administration.
Peak Plasma TimePeak plasma concentrations are reached within 30 to 60 minutes after oral administration.
Duration of ActionThe antibacterial effect of a single dose generally lasts for about 6 to 8 hours, depending on the susceptibility of the organism and the dose administered.

How It Works

Cefaclor exerts its bactericidal effect by binding to penicillin-binding proteins (PBPs) located on the inner bacterial cell membrane. This binding inhibits the transpeptidation reaction necessary for cross-linking peptidoglycan chains in the bacterial cell wall. As a result, the cell wall becomes weakened and osmotically unstable, leading to bacterial cell lysis and death. Cefaclor is active against a range of gram-positive and gram-negative bacteria, but it is susceptible to hydrolysis by certain beta-lactamases.

Mechanism Steps

1
Binding to penicillin-binding proteins: Cefaclor binds to specific penicillin-binding proteins on the bacterial cell membrane, which are enzymes involved in cell wall synthesis.
2
Inhibition of transpeptidation: This binding inhibits the transpeptidase activity, preventing the cross-linking of peptidoglycan strands that provide structural integrity to the bacterial cell wall.
3
Cell wall weakening and lysis: Without proper cross-linking, the cell wall becomes weak and cannot withstand osmotic pressure, leading to bacterial cell lysis and death.
