Evidence-based practical advice from experienced clinicians

1

Always administer this medicine in a hospital setting with resuscitation facilities available.

2

Monitor blood glucose closely before and after each dose to prevent hypoglycaemia.

3

Perform an ECG before and during treatment to monitor for QT prolongation.

4

Adjust the dose in patients with renal or hepatic impairment.

5

Avoid concurrent use with other QT-prolonging drugs.

6

Educate patients about the symptoms of cinchonism and when to report them.

7

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionFollowing intramuscular administration, quinine is absorbed rapidly and almost completely from the injection site. Peak plasma concentrations are typically reached within 1 to 3 hours. The absorption rate may be reduced in patients with poor peripheral circulation, such as those in shock.

DistributionQuinine is widely distributed throughout the body, including the central nervous system, liver, kidneys, and spleen. It crosses the placenta and is excreted in breast milk. The apparent volume of distribution is approximately 1 to 2 L/kg in healthy adults, but may be increased in patients with severe malaria.

Protein BindingApproximately 70% to 80% of quinine is bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein. Protein binding may be decreased in patients with severe malaria or malnutrition.

MetabolismQuinine is extensively metabolized in the liver, primarily by cytochrome P450 enzymes, including CYP3A4, CYP2C19, and CYP2D6. The major metabolites are 3-hydroxyquinine and 2'-quininone, which have reduced antimalarial activity.

Half-LifeThe elimination half-life of quinine is approximately 8 to 12 hours in healthy adults. In patients with severe malaria, the half-life may be prolonged to 18 hours or more. In patients with hepatic impairment, the half-life is significantly prolonged.

ExcretionQuinine and its metabolites are primarily excreted in the urine. About 20% of the administered dose is excreted unchanged in the urine. Renal clearance is reduced in patients with renal impairment, and dose adjustment may be necessary.

BioavailabilityBioavailability following intramuscular administration is approximately 90% to 100%, which is comparable to intravenous administration. This makes the intramuscular route suitable when intravenous access is not available.

Onset of ActionThe antimalarial effect begins within 1 to 2 hours after intramuscular injection, with a reduction in fever and parasitaemia observed within 24 to 48 hours.

Peak Plasma TimePeak plasma concentrations are reached approximately 1 to 3 hours after intramuscular injection.

Duration of ActionThe antimalarial effect lasts for approximately 8 to 12 hours, corresponding to the elimination half-life. Repeat dosing is usually required every 8 to 12 hours depending on the clinical response.

How It Works

This medicine works by accumulating in the food vacuole of the malaria parasite, where it interferes with the digestion of host haemoglobin. Quinine forms a complex with haem, preventing its conversion into harmless haemozoin. The resulting toxic haem-quinine complex damages the parasite's membranes and leads to its death. It also has mild effects on the parasite's nucleic acid metabolism and may affect the parasite's ability to invade red blood cells.

Mechanism Steps

1

Accumulation in parasite food vacuole: Quinine concentrates in the acidic food vacuole of the malaria parasite due to its weak base properties.

2

Binding to haem: Inside the vacuole, quinine binds to haem, which is released during haemoglobin digestion.

3

Prevention of haemozoin formation: The quinine-haem complex cannot be converted into inert haemozoin crystals, leading to accumulation of toxic haem.

4

Parasite membrane damage: The toxic haem-quinine complex disrupts the parasite's cell membranes and causes oxidative damage.

5

Parasite death: The combined effects lead to the death of the malaria parasite and clearance from the bloodstream.

Dosage Information

Adult Dosage	The dose of this medicine must be individualized by a qualified clinician based on the severity of malaria, patient weight, renal and hepatic function, and clinical response. A typical adult dose is 600 mg intramuscularly every 8 to 12 hours, but the exact regimen depends on the clinical situation. It is usually given for at least 24 hours until oral therapy can be started. Do not self-administer.
Pediatric Dosage	Pediatric dosing is not established from available information. Consult a pediatrician. Quinine dosing in children is weight-based and must be determined by a qualified clinician.
Elderly Dosage	Elderly patients may require lower doses due to reduced renal and hepatic function. Close monitoring for side effects is recommended. Dose must be individualized by a qualified clinician.
Renal Impairment	In patients with renal impairment, dose reduction may be necessary. Monitor renal function and adjust dose accordingly. Consult a nephrologist or clinical pharmacist for guidance.
Hepatic Impairment	In patients with hepatic impairment, dose reduction may be necessary due to reduced metabolism. Monitor liver function and adjust dose accordingly. Consult a hepatologist for guidance.
Maximum Daily Dose	The maximum daily dose is not established from available information. It must be determined by a qualified clinician based on individual patient factors.

Additional Safety Advice

General Safety

This medicine must only be given by a qualified healthcare professional in a setting equipped to manage severe allergic reactions and cardiac emergencies. Do not attempt to self-administer this injection. Inform your doctor if you have heart problems, kidney or liver disease, diabetes, or a history of low blood sugar. Your doctor will monitor your heart rhythm, blood pressure, blood sugar, and vision during treatment. Avoid alcohol while receiving this medicine because it can worsen low blood sugar and increase the risk of heart rhythm problems. Tell your doctor about all other medicines you are taking, especially those that affect heart rhythm or blood sugar. If you notice ringing in the ears, vision changes, or unusual bleeding, report it immediately. Keep all follow-up appointments and blood tests as scheduled.

👴 Special Considerations for Elderly

💡 For Patients Above 65

Elderly patients are more susceptible to the side effects of this medicine, especially hypoglycaemia, cardiac arrhythmias, and cinchonism. Dose reduction may be necessary, and close monitoring is essential.

🤰 Pregnancy Planning (TTC)

If you are planning pregnancy, consult your doctor before traveling to a malaria-endemic area. Quinine is not recommended for malaria prophylaxis in pregnancy. Use effective contraception if you are taking this medicine and discuss family planning with your doctor.

🏥 Post-Surgery Considerations

If you have recently had surgery, inform your surgeon and anesthesiologist if you are receiving this medicine. It can interact with anaesthetic agents and affect heart rhythm and blood sugar.

🦷 Dental Procedures

Inform your dentist if you are receiving this medicine. It may interact with local anaesthetics and affect blood sugar. Your dentist may need to take precautions.
