How long does quinine treatment last?
Even with seven-day treatment durations, evaluations of different quinine dosage regimens have revealed interesting trends. Doses of 10 mg/kg/day given twice daily for 7 days were associated with day 28 treatment failure rates as high as 30%[37]. Increasing the quinine dosage to 15 mg/kg/day or 20 mg/kg/day improved treatment outcomes, with failure rates ranging from 8% to 14%[37], although potential increases in toxicity with higher dosages are a concern. The treatment regimen currently recommended in sub-Saharan Africa is 10 mg/kg of the base given 8 hourly for 7 days. This regimen was associated with a lower rate of recurrent infections on day 28 (6.3%) compared to the 10 mg/kg twice daily regimen (16.1%)[44].
What is Quinine used for?
Quinine, an old anti-malarial drug in a modern world: role in the treatment of malaria
How is quinine absorbed?
Quinine is rapidly absorbed both orally and parenterally, reaching peak concentrations within 1-3 hours[8] . It is distributed throughout the body fluids and is highly protein bound, mainly to alpha-1 acid glycoprotein. The binding capacity in plasma is concentration dependent, but also depends on the levels of alpha-1 acid glycoprotein, which therefore makes comparisons between different studies difficult[9]. Quinine readily crosses the placental barrier and is also found in cerebral spinal fluid. Excretion is rapid - 80% of the administered drug is eliminated by hepatic biotransformation and the remaining 20% is excreted unchanged by the kidney [10-12]. The half-life of quinine ranges between 11-18 hours [13,14]. Several pharmacokinetic characteristics of quinine differ according to the age of the subject and are also affected by malaria. The volume of distribution is less in young children than in adults, and the rate of elimination is slower in the elderly than in young adults. In patients with acute malaria the volume of distribution is reduced and systemic clearance is slower than in healthy subjects; these changes are proportional to the severity of the disease. As a result, plasma quinine levels are higher in patients with malaria. Protein binding of quinine is increased in patients with malaria as a result of an increased circulating concentration of alpha-1 acid glycoprotein [15].
What are the side effects of quinine?
The side effects commonly seen at therapeutic concentrations are referred to as cinchonism, with mild forms including tinnitus, slight impairment of hearing, headache and nausea. Impairment of hearing is usually concentration dependent and reversible [17]. More severe manifestations include vertigo, vomiting, abdominal pain, diarrhea, marked auditory loss, and visual symptoms, including loss of vision. Hypotension may occur if the drug is given too rapidly, and venous thrombosis may occur following intravenous injections [10]. Intramuscular administration is painful and may cause sterile abscesses. Hypoglycaemia is yet another common side effect of quinine therapy [15,18] and is a particular problem in pregnant women[19]. Hypoglycaemia has been reported to occur in up to 32% of patients receiving quinine therapy[18]. However in more recent studies, hypoglycaemia occurred in only 3% of adults and 2.8% of African children receiving quinine [20,21]. Less frequent but more serious side effects of quinine therapy include skin eruptions, asthma, thrombocytopaenia, hepatic injury and psychosis [22].

Is Act a good treatment for malaria?
The advent of ACT has provided important new therapeutic options for the management of uncomplicated malaria in regions with high prevalence of multi-drug resistant malaria. A few available trials have shown superiority of ACT over quinine in the management of uncomplicated malaria [32,45,46]. In Brazil, patients treated with artemether-lumefantrine (AL) had significantly faster parasite clearance times when compared to those treated with quinine+doxycycline [46]. Considering the extensive available data, quinine should not be used to treat uncomplicated malaria when ACT is available [27,45]. ACT has the advantages of simplicity of dosing, which promotes adherence to therapy when compared with the seven-day treatment courses of quinine [32,45], better tolerance and decreased risks of serious toxicity.

What is Quinine used for?
Quinine, as a component of the bark of the cinchona (quina-quina) tree, was used to treat malaria from as early as the 1600s, when it was referred to as the "Jesuits' bark," " cardinal's bark," or "sacred bark.".
What causes quinine to fail?
Treatment failures with quinine could also be explained by varying pharmacokinetic profiles of the drug. It is known that quinine pharmacokinetic properties and therapeutic responses vary with age, pregnancy, immunity and disease severity [ 99 ]. Also, as patients recover from malaria, there is usually an expansion of the volume of distribution and an increase in systemic clearance of quinine resulting in a decline in the average concentration of quinine in plasma [ 100 ]. These variations may lead to drug levels that may be inadequate to completely clear infection. The possibility that pharmacokinetic factors may explain quinine treatment failure was initially raised about 20 years ago when a Thai patient who had fatal severe malaria and apparent RIII resistance was found to have abnormally low levels of quinine despite adequate dosing [ 101 ]. Additional evidence for the impact of unusual quinine pharmacokinetics on treatment outcomes was provided by a more recent study describing early treatment failure in a patient with severe malaria with an abnormally high volume of distribution and increased quinine clearance, resulting in abnormally low quinine concentrations [ 102 ]. A few studies have proposed that an increase in the quinine dosage after the third day could compensate for declines in plasma drug levels during recovery, especially in areas with resistant P. falciparum [ 99 ]. However, this is not routinely practiced. Despite these anecdotal observations, there is little evidence for large variations in quinine pharmacokinetics [ 103] and the exact role that variations in drug levels play in quinine treatment responses is unclear.

Does quinine increase malaria?
As a result, plasma quinine levels are higher in patients with malaria. Protein binding of quinine is increased in patients with malaria as a result of an increased circulating concentration of alpha-1 acid glycoprotein [ 15 ].

How many grains of quinine were used in the first wave of trials?
Most authors mentioned by Magendie ( 1829) used an initial 3-5 grains of quinine powder in pills. The administration was repeated, usually no more frequently than twice a day, until complete disappearance of rigors. Elliotson kept to 5 grains every 6 hours. Italian doctors reported the daily use of up to 25 grains to treat severe and relapsing intermittent fevers. Despite the variations and uncertainties in the reports, Magendie ( 1829) gathered evidence that looks like a crude dose-response study: less than 2 grains a day was ineffective, and more than 15 grains a day was found to be either actually toxic (leading to tinnitus and vomiting, for example) or simply badly tolerated by patients. Assuming that quinine preparations were pure and identically prepared – which is far from certain – consensus on the treatment of intermittent fevers rested on the administration of 5 to 15 grains of quinine per day, usually in several doses, although with noticeable local variations.
How many grains of Quinine and Cinchonina were injected into dogs?
Magendie, who administered them to dogs in large doses without nausea, vomiting, or other apparent result. The indefatigable and acute physiologist then injected into the veins of these animals from two to ten grains of the sulphate and of the acetate of Quinine and Cinchonina in solution, but with no more effect. Satisfied of the innocence of the substances, he ordered the sulphate of quinine to several scrofulous children affected with ulcers [ possibly tuberculosis of the lymph glands ], and in a fortnight the most decided benefit was obtained.
What was the Malaria Commission's conclusion?
After examining clinical and statistical data on malaria gathered during the 19th century, the Malaria Commission of the League of Nations concluded that few of the data were sufficiently reliable to be used in comparative studies (Malaria Commission 1925). The principal writer of the report, Nicolaas Swellengrebel (Verhave 2011), pointed out that a shift in the meaning of the word malaria had occurred: from ‘mal-aria’ (bad air) as the cause of many fevers, to the name of a disease (‘plasmodiosis’) reflecting the causative parasites – Plasmodia.
