Actions of Penicillin V in details
Penicillin V V commonly known as phenoxymethylpenicillin, belongs to a class of drugs called antibiotics. Penicillin V V inhibits the essential proteins required for growth and multiplication of bacteria, thereby killing the bacteria and preventing the infection
How should I take Penicillin V?
Take Penicillin V exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
You may take this medicine with or without food.
To be sure Penicillin V is helping your condition, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled visits to your doctor.
Take Penicillin V for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Penicillin V will not treat a viral infection such as the common cold or flu. Do not give this medication to another person, even if they have the same symptoms you do.
This medication can cause you to have unusual results with certain medical tests. Tell any doctor who treats you that you are using Penicillin V.
Store Penicillin V tablets at room temperature away from moisture, heat, and light.
Penicillin V administration
Oral:
Administer around-the-clock to promote less variation in peak and trough serum levels. Take on an empty stomach 1 hour before or 2 hours after meals, to enhance absorption.Penicillin V pharmacology
Penicillin V V exerts a bactericidal action against Penicillin V-sensitive microorganisms during the stage of active multiplication. It acts through the inhibition of biosynthesis of cell-wall mucopeptide. It is not active against the penicillinase-producing bacteria, which include many strains of staphylococci. The drug exerts high in vitro activity against staphylococci (except penicillinase-producing strains), streptococci (groups A, C, G, H, L, and M), and pneumococci. Other organisms sensitive in vitro to Penicillin V V are Corynebacterium diphtheriae, Bacillus anthracis, Clostridia, Actinomyces bovis, Streptobacillus moniliformis, Listeria monocytogenes, Leptospira, and Neisseria gonorrhoeae. Treponema pallidum is extremely sensitive.
The potassium salt of Penicillin V V has the distinct advantage over Penicillin V G in resistance to inactivation by gastric acid. It may be given with meals; however, blood levels are slightly higher when the drug is given on an empty stomach. Average blood levels are two to five times higher than the levels following the same dose of oral Penicillin V G and also show much less individual variation.
Once absorbed, Penicillin V V is about 80% bound to serum protein. Tissue levels are highest in the kidneys, with lesser amounts in the liver, skin, and intestines. Small amounts are found in all other body tissues and the cerebrospinal fluid. The drug is excreted as rapidly as it is absorbed in individuals with normal kidney function; however, recovery of the drug from the urine indicates that only about 25% of the dose given is absorbed. In neonates, young infants, and individuals with impaired kidney function, excretion is considerably delayed.
