PHARMACOLOGICAL CLASSIFICATION:
A.20.1.2 Penicillins

PHARMACOLOGICAL ACTION:
a) Bacteriology
(i) Spectrum
Suprapen exhibits in vitro and in experimental animals in vivo, bactericidal activity against a wide range of Gram-positive and Gram-negative bacteria. The following are among the more commonly encountered sensitive organisms:

Gram-positive bacteria Gram-negative bacteria
Streptococcus pyogenes Neisseria gonorrhoeae
Strep. faecalis Neisseria meningitidis
Strep. viridans Haemophilus influenzae
Dip. pneumoniae Ischerichia coli
Staphylococcus aureus Salmonella typhi
(penicillin sensitive) Salmonella species
Staphylococcus aureus Proteus mirabilis
(penicillinase producing) Bordetella pertussis
Corynebacterium species Shigella species
Clostridium species Brucella species
Bacillus anthracis 
(ii) Synergism 
Suprapen exhibits synergistic bactericidal activity in vitro, and in experimental animals in vivo against some ampicillin-resistant organisms.

(iii) Additive effects
The two components of Suprapen –amoxycillin and flucloxacillin – generally exhibit an additive effect against sensitive bacteria and bacteria that are sensitive to amoxycillin or to flucloxacillin remain sensitive to the combination, showing that antagonism does not occur when the two components are combined.

(b) Absorption
Suprapen is well absorbed orally. Peak serum levels are achieved 1 to 2 hours after dosing.

(c)ExcretionApproximately 50% of the dose is excreted unchanged into the urine within 6 hours, resulting in high urine levels of active drug.

INDICATIONS:
Suprapen
is indicated for the treatment of a wide range of bacterial infections, caused by susceptible organisms; in particular infections of mixed origin where penicillin-resistant staphylococci may be implicated or where the causative organism is unknown.

Typical indications include:
Acute and chronic bronchitis Pelvic inflammatory disease
Pneumonia Urinary tract infections
Ear, nose and throat infections Skin and soft tissue infections
Gynaecological infections 
CONTRA-INDICATIONS:
Suprapen
should not be given to those subjects hypersensitive to penicillin. As there is currently no neonatal formulation Suprapen should not be given to neonates.

DOSAGE AND DIRECTIONS FOR USE:
Adults:
One 500 mg capsule three times a day.
Children 2–12: 5 mL of syrup (containing 250 mg Suprapen) three times a day.
Children under 2: 2,5 mL of syrup (containing 125 mg Suprapen) three times a day.
Neonates: No formulation is available at present.

In severe infections these dosages may safely be increased.
To ensure maximal absorption Suprapen should be given in the fasting state, i.e. approximately 1 hour before a meal.

SIDE-EFFECTS AND SPECIAL PRECAUTIONS:
As with other penicillins, side-effects are rare and usually of a mild and transitory nature. Allergic reactions may occur, and these are normally mild in nature, presenting as a pruritic skin rash, an erythematous skin reaction or urticaria. In this event withdrawal of Suprapen and administration of an antihistamine will suffice in most cases. Should a serious anaphylactic reaction occur, the drug should be discontinued and the patient treated with the usual agents: (adrenaline, corticosteroids and antihistamines). Treatment with Suprapen may give rise to a maculopapular rash during therapy or within a few days after completion thereof. The incidence of maculopapular rash is especially high in patients suffering from infectious mononucleosis.

The use of this antibiotic may lead to the appearance of resistant strains of organisms and sensitivity testing should, therefore, be carried out wherever possible, to ensure the appropriateness of the therapy.

Hepatitis and cholestatic jaundice have been reported rarely.

KNOWN SYMPTOMS OF OVERDOSAGE AND PARTICULARS OF ITS TREATMENT:
No known symptoms of overdosage.
As with all penicillins, oral administration can cause gastro-intestinal symptoms such as transient diarrhoea, nausea and colic which are dose related and a result of local irritation not toxicity.
