Anne Miller’s physician, Bumstead, went to Fulton with a plea. Aware of Fulton’s friendship with Florey, Bumstead asked Fulton if he could obtain a sample of penicillin.

“Fulton got on the telephone on Thursday,” recalled Lycurgus M. ’43, HS ’52, “and by Saturday they had a small quantity of penicillin to give to Mrs.

Miller.” It took several phone calls to track down officers of Merck and Co., which had produced a small amount of the antibiotic.

A sample was flown to New Haven from Washington and delivered to the hospital by a state trooper. “At that time they did not know how much to give or how to give it because they were in the very early stages,” recalled Rocko Fasanella, M.D. At the time, it had saved four of six patients

Herbert Tabor, M.D., HS ’43, the intern with primary responsibility for injecting the drug, had another task. He saved Miller’s urine and sent it back to Merck, where up to 70 percent of the scarce and costly drug could be recovered and reused. Ogden Miller, who for four weeks had been going downhill with what appeared, on the basis of all previous experience, to be a fatal hemolytic streptococcus septicemia.

She had had a temperature ranging from 103 to 106.5 degrees steadily for four weeks despite liberal administration of the sulfa drugs.

It is still too soon to say she is cured, but the response has been most dramatic.” Miller went on to live a full and productive life. Although clinical trials were under way, Tabor, who went on to a career at the National Institutes of Health, believes Miller’s recovery convinced the pharmaceutical industry that the antibiotic was viable and worthy of mass production. “That was really the importance of this case,” said Tabor.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.

The dose of Amoxicillin that is selected to treat an individual infection should take into account: • The expected pathogens and their likely susceptibility to antibacterial agents (see section 4.4) • The severity and the site of the infection. • The age, weight and renal function of the patient; as shown below.

The duration of therapy should be determined by the type of infection and the response of the patient, and should generally be as short as possible. Some infections require longer periods of treatment (see section 4.4 regarding prolonged therapy).

Severe infections of the ear, nose and throat (such as mastoiditis peritonsillar infections, epiglottis and sinusitis when accompanied by severe systemic signs and symptoms. 750 mg to 2 g every 8 hours, or 2 g every 12 hours, maximum of 12 g/day.

3 Susceptibility to amoxicillin can be inferred from ampicillin.

4 The susceptibility of streptococcus groups A, B, C and G to penicillins is inferred from the benzylpenicillin susceptibility. 5 Breakpoints relate only to non-meningitis isolates. For isolates categorised as intermediate to ampicillin avoid oral treatment with amoxicillin.

Susceptibility inferred from the MIC of ampicillin. 6 Breakpoints are based on intravenous administration.

Beta-lactamase positive isolates should be reported resistant. 7 Beta lactamase producers should be reported resistant.

8 Susceptibility to amoxicillin can be inferred from benzylpenicillin.

9 The breakpoints are based on epidemiological cut-off values (ECOFFs), which distinguish wild-type isolates from those with reduced susceptibility.

10 The non-species related breakpoints are based on doses of at least 0.5 g x 3or 4 doses daily (1.5 to 2 g/day).

The prevalence of resistance may vary geographically and with time for selected species, and local information on resistance is desirable, particularly when treating severe infections.

As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is questionable.

? Almost all S.aureus are resistant to amoxicillin due to production of penicillinase.

In addition, all methicillin-resistant strains are resistant to amoxicillin. The pharmacokinetic results for studies in which amoxicillin was administered to groups of healthy volunteers given as a bolus intravenous injection are presented below.

Peak serum conc (?g/ml) Urinary recovery (%, 0 to 6 h ) About 18% of total plasma amoxicillin is bound to protein and the apparent volume of distribution is around 0.3 to 0.4 l/kg. Following intravenous administration, amoxicillin has been found in gall bladder, abdominal tissue, skin, fat, muscle tissues, synovial and peritoneal fluids, bile and pus.

Amoxicillin does not adequately distribute into the cerebrospinal fluid.

From animal studies there is no evidence for significant tissue retention of drug-derived material.

Amoxicillin, like most penicillins, can be detected in breast milk (see section 4.6).

Amoxicillin is partly excreted in the urine as the inactive penicilloic acid in quantities equivalent to up to 10 to 25% of the initial dose.

The major route of elimination for amoxicillin is via the kidney.

Amoxicillin has a mean elimination half-life of approximately one hour and a mean total clearance of approximately 25 l/hour in healthy subjects. Approximately 60 to 70% of the amoxicillin is excreted unchanged in urine during the first 6 hours after administration of a single 250 mg or 500 dose of amoxicillin. Various studies have found the urinary excretion to be 50 to 85% for amoxicillin over a 24 hour period.

Concomitant use of probenecid delays amoxicillin excretion (see section 4.5). Following oral administration of amoxicillin to healthy mox 250 mg tablet uses males and female subjects, gender has no significant impact on the pharmacokinetics of

amoxicillin

The elimination half-life of amoxicillin is similar for children aged around 3 months to 2 years and older children and adults. For very young children (including preterm newborns) in the first week of life the interval of administration should not exceed twice daily administration due to immaturity of

Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. The total serum clearance of amoxicillin decreases proportionately with decreasing renal function (see section 4.2).

Hepatically impaired patients should be dosed with caution and hepatic function monitored at regular intervals.

Non-clinical data reveal no special hazard for humans based on studies of safety pharmacology, repeated dose toxicity, genotoxicity and toxicity to reproduction and development.

Carcinogenicity studies have not been conducted with amoxicillin. Amoxicillin should not be mixed with blood products, other proteinaceous fluids such us protein hydrolysates or with intravenous lipid emulsions.

If prescribed concomitantly with an aminoglycoside, the antibiotics should not be mixed in the syringe, intravenous fluid container or giving set because of loss of activity of the aminoglycoside under these conditions. Amoxicillin and aminoglycoside injections should be administered at separate sites.

Amoxicillin should not be mixed with ciprofloxacin.

Opposing him in the studio was actor Peter Egan, and anti-vivisection scientific advisor Andre Menache was shown on a screen live from Paris.

Both Mr Egan and Dr Menache make a number of claims in the interview and, it’s important to understand how they might have come to one conclusion or another. If you’re starting from a position of wanting to understand rather than dogmatically trying to

Claim: There is no peer-regulated oversight over animal experiments.

It is very hard to imagine where this might have come from. Every single experiment undergoes peer-regulated oversight in a number of different ways. Firstly an Animal Welfare and Ethical Review Body made up of peers and colleagues at the scientist’s own establishment determines whether or not an experiment can take place.

On these sit scientists, animal care staff, vets and perhaps lay members of the public. The Home Office also oversees each application as the UK enjoys both national and local ethical review. Finally, the work of the responsible government minister is advised by the Animals in Science Committee, which again has a range of members including, currently, a representative from PETA and one from the RSPCA.

Beyond this, every experiment is published on the Home Office website written in plain English and the UK has been inspecting animal experiments since 1876. In fact, the UAR office has all of the annual returns of animals used

since

Where could this have come from: They are both exaggerations of a misunderstanding. The British Medical Journal (BMJ) ran an editorial in 2014 which correctly asserted that poorly designed experiments led to bad results.

However, it does not follow that well designed experiments give poor results. The editorial was not focused on the concept of using animals, and it did not claim that animals cannot predict human responses.

A director of the US food and Drug Administration (FDA) Mike Leavitt claimed in 2006 that “ Currently, nine out of ten experimental drugs fail in clinical studies because we cannot accurately predict how they will behave in people based on laboratory and animal studies ”. The misunderstanding in this case centres around how animals are used in drug development because they are very good at detecting whether a new drug is toxic at the intended dose, but not as good at predicting whether a drug is effective. Leavitt is talking about the latter and of course mentions ‘ laboratory and animal experiments’ i.e. everything that is not a human trial including computer models and cell cultures. Leavitt’s comment is also not quite accurate since there are numerous reasons that drug development is abandoned. In 32% of cases it is because the company developing it rationalised their portfolio. Verdict: The BMJ did contain an editorial raising concerns over the need for good experimental design.
