phenoxymethyl penicillin
Noun: A semisynthetic penicillin antibiotic, chemically and therapeutically similar to penicillin G (benzylpenicillin), but characterized by greater stability in acidic environments, particularly gastric acid. This property allows it to be administered orally. It is primarily used to treat mild to moderate infections caused by susceptible Gram-positive bacteria.
This term is used in medical, pharmaceutical, and biological contexts to refer to a specific antibiotic compound. It is a technical term. * The doctor prescribed phenoxymethyl penicillin for the child's streptococcal pharyngitis. * Phenoxymethyl penicillin is often the first-line treatment for uncomplicated skin and soft tissue infections. * The stability of phenoxymethyl penicillin in stomach acid makes it suitable for oral administration.
- Chemical Context: In pharmacology, it is described as the phenoxymethyl analog of penicillin, with the chemical formula C₁₆H₁₈N₂O₅S.
- Comparative Efficacy: It is often discussed in comparison to penicillin G, highlighting its oral bioavailability versus the parenteral (injection) route required for penicillin G.
- Penicillin V: The most common name for this antibiotic in clinical practice. "Phenoxymethyl penicillin" is the systematic chemical name, while "Penicillin V" is the generic drug name.
- Oral Penicillin: A descriptive term that often refers specifically to phenoxymethyl penicillin due to its common use as the primary oral form of penicillin.
- Acid-stable penicillin: A descriptive term highlighting its key pharmacological property.
- Penicillin V
- Pen V (common abbreviation)
- Penicillin G (Benzylpenicillin): The original, naturally occurring penicillin from which phenoxymethyl penicillin is derived; it is not acid-stable.
- Broad-spectrum penicillin: A class of penicillins (e.g., amoxicillin, ampicillin) effective against a wider range of bacteria than phenoxymethyl penicillin.
- Beta-lactam antibiotic: The larger class of antibiotics that includes all penicillins.
- a crystalline penicillin similar in action to penicillin G but more resistant to the action of gastric acids
