Kopen description
Kopen (Penicillin V) is narrow spectrum antibiotic used to treat mild to moderate infections caused by susceptible bacteria. It is a natural penicillin antibiotic that is administered orally. Penicillin V may also be used in some cases as prophylaxis against susceptible organisms. Natural penicillins are considered the drugs of choice for several infections caused by susceptible gram positive aerobic organisms, such as Streptococcus pneumoniae, groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridans group streptococci, and non-penicillinase producing staphylococcus. Aminoglycosides may be added for synergy against group B streptococcus (S. agalactiae), S. viridans, and Enterococcus faecalis. The natural penicillins may also be used as first or second line agents against susceptible gram positive aerobic bacilli such as Bacillus anthracis, Corynebacterium diphtheriae, and Erysipelothrix rhusiopathiae. Natural penicillins have limited activity against gram negative organisms; however, they may be used in some cases to treat infections caused by Neisseria meningitidis and Pasteurella. They are not generally used to treat anaerobic infections. Resistance patterns, susceptibility and treatment guidelines vary across regions.
Kopen dosage
Adults: 250-500 mg every 6 hrs.
Children: Suggested dosage for infants and children is 50 mg/kg body weight/day in 4 divided doses. To be given every 6 hrs.
Children 7-12 years: 5-10 mL (1-2 tsp) of Kopen 250 mg/5 mL; 3-6 years: 5-10 mL (1-2 tsp) of Kopen 125 mg/5 mL or 5 mL (1 tsp) of Kopen 250 mg/5 mL; 1-2 years: 5 mL (1 tsp) of Kopen 125 mg/5 mL or 2.5-5 mL of Kopen 250 mg/5 mL.
Usual duration of therapy is from 10-14 days. Or as prescribed by the physician.
Kopen interactions
Kopen should not be combined with bacteriostatic antibiotics. Combinations with other antibiotics should be considered if their effects can be expected to be synergistic or at least additive. The combination partners should be fully dosed. (Exception: In combination with a proven synergistic action, the dose of the more toxic combination partner may be reduced.) Competitive inhibition of drug elimination should be remembered, whenever anti-inflammatories, antirheumatics, antipyretics (particularly indomethacin, phenylbutazone, salicylates in high doses) or probenecid are used concomitantly. Ingestion of Kopen with meals reduce the absorption of the drug. Like other antibiotics, Kopen may reduce the efficacy of oral contraceptives. During treatment with Kopen non-enzymatic urinary glucose tests and uribilinogen tests may be false-positive. Urinary amino acid quantitations with ninhydrin may also be false-positive.
Kopen side effects
Kopen may produce diarrhoea, nausea and heartburn. Allergic reactions which may include exfoliative dermatitis, other skin rashes, interstitial nephritis and vasculitis, may occur.
A generalised sensitivity reaction with urticaria, fever, joint pains and eosinophilia can develop within a few hours to several weeks after starting treatment. Superinfection by resistant species, such as Pseudomonas or Candida, which do not respond to penicillin therapy may occur. A sore mouth and a black hairy tongue have been reported.
Increases in liver enzyme values have been reported. Care should be taken when high doses are given to patients with renal impairment (because of the risk of neurotoxicity) or congestive heart failure.
Renal and haematological systems should be monitored during prolonged and high dose therapy.
Care should be taken when treating patients with syphilis, as the Jarisch-Herxheimer reaction may occur shortly after starting treatment. This reaction, manifesting as fever, chills, headache and reactions at the site of the lesion, can be dangerous in cardiovascular syphilis or where there is a serious risk of increased local damage such as with optic atrophy.
Haemolytic anaemia and leucopenia, prolongation of bleeding time and defective platelet function have been observed. Convulsions and other signs of toxicity to the CNS may occur particularly in patients with renal failure.
Disturbances of blood electrolytes may follow the administrations of large doses of this medicine.
High doses should be used with caution in patients receiving potassium containing medicines or potassium-sparing diuretics.
Kopen contraindications
Kopen should not be given to patients known to be allergic to penicillin and should be given with care to patients with a history of allergy to cephalosporins. Cases of cross sensitivity have been reported. It should not be given to babies, in the neonatal period, born of hypersensitive mothers. It is not recommended for chronic, severe or deep-seated infections such as subacute bacterial endocarditis, meningitis or syphilis.
