Description
(extracted from source data)
HALF-LIFE Upon oral administration, the half-life is about 30 minutes. It can last up to 4 hours in patients with renal impairment.[L6412]
ROE While the drug is rapidly excreted, only 25% of the total dose is detected in the urine. Renal excretion may be delayed in neonates, young infants, and patients with renal impairment.[label]
INDICATION Indicated for the treatment of mild to moderately severe infections due to penicillin G­-sensitive microorganisms, with the use of bacteriological studies (including sensitivity tests) and clinical response.[label] ; ; Phenoxymethylpenicillin may be used for the treatment of: ; ; - mild to moderate infections of the upper respiratory tract, scarlet fever, and mild erysipelas caused by Streptococcus without bacteremia; - mild to moderately severe infections of the respiratory tract caused by Pneumococcus; - mild infections of the skin and soft tissues caused by penicillin G-sensitive Staphylococcus; - mild to moderately severe infections of the oropharynx caused by Fusospirochetosis, including Vincent’s gingivitis and pharyngitis, usually respond to oral penicillin therapy; ; **Off-label**; ; Indicated for use as prophylaxis against bacterial endocarditis in patients with congenital heart disease or rheumatic or other acquired valvular heart disease when they undergo dental procedures and surgical procedures of the upper respiratory tract.[label]
MOA Phenoxymethylpenicillin inhibits the biosynthesis of cell wall mucopeptide [label] by binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, which are critical in the cell wall synthesis and maintenance, as well as cell division.[L6412] This disrupts the third and last stage of bacterial cell wall synthesis. This subsequently leads to cell lysis.[L6412]
TOXICITY The oral LD50 is >1040 mg/kg in rats. Nausea, vomiting, black hairy tongue, and epigastric distress are common reactions to oral penicillins.[label] In rare cases, neuromuscular sensitivity and seizures may be seen with antibiotics and supportive treatments are advised and further drug absorption should be limited through induced emesis or gastric lavage, followed by administration of activated charcoal.[L6418] Severe hypersensitivity reactions, often leading to death, have been reported with penicillin therapies.[label] Although phenoxymethylpenicillin was shown to be excreted in human breast milk, the use of this drug in pregnant or nursing women is regarded generally safe.[L6415]
ABSORPTION Upon oral administration, phenoxymethylpenicillin is rapidly but incompletely absorbed.[A178612] The bioavailability of phenoxymethylpenicillin ranges from 25 to 60%.[A178618] Compared to the free acid form of the drug, the calcium or potassium salts of phenoxymethylpenicillin displays better absorption profiles. It is reported that fasting state enhances the drug absorption. The peak plasma concentrations of 200 to 700 ng/mL are achieved in 2 hours following an oral dose of 125 mg. Following an oral dose of 500 mg, the peak plasma concentrations of 3 to 5 μg/mL are reached in 30 to 60 minutes post-dose.[L6412]
DESCRIPTION Phenoxymethylpenicillin is a β-lactam, natural penicillin antibacterial. It has broad-spectrum activity against Gram-positive aerobes, limited activity against Gram-negative organisms, and is not generally used against anaerobes. (GtoPdb)
PHARMACODYNAMICS Phenoxymethylpenicillin works against penicillin-sensitive microorganisms with bactericidal effects. It targets the bacteria during its active multiplication stage by interfering with bacterial cell wall peptidoglycan synthesis. _In vitro_, phenoxymethylpenicillin was shown to be active against staphylococci (except penicillinase-producing strains), streptococci (groups A, C, G, H, L and M), and pneumococci, as well as _Corynebacterium diphtheriae_, _Bacillus anthracis_, Clostridia, _Actinomyces bovis_, _Streptobacillus moniliformis_, _Listeria monocytogenes_, _Leptospira_, _Neisseria gonorrhoeae_, and _Treponema pallidum_.[label]
