Eroqeen Syrup
Eroqeen Syrup Uses, Dosage, Side Effects, Food Interaction and all others data.
Eroqeen Syrup is used for malarial prophylaxis (as a suppressive) and in managing acute attacks of malaria. It is highly active against erythrocytic forms of P. vivax, P. malariae and P. falciparum. It influences Hb digestion by increasing intravesicular pH in malaria parasite cells and interferes with the nucleoprotein synthesis of the patient. It is also effective in extra intestinal amoebiasis. In RA chloroquine and more effectively hydroxychloroquine have a disease-modifying effect.
Eroqeen Syrup inhibits the action of heme polymerase, which causes the buildup of toxic heme in Plasmodium species. It has a long duration of action as the half life is 20-60 days. Patients should be counselled regarding the risk of retinopathy with long term usage or high dosage, muscle weakness, and toxicity in children.

Uses
Eroqeen Syrup Phosphate is used for the treatment of malaria, prophylaxis and suppression of malaria, amoebic hepatitis and abscess, discoid and systemic and systemic lupus erythematosus, rheumatoid arthritis
Eroqeen Syrup is also used to associated treatment for these conditions: Discoid Lupus Erythematosus (DLE), Extraintestinal Amebiasis, Plasmodium Infections, Polymorphic Light Eruption (PLE), Porphyria Cutanea Tarda, Rheumatoid Arthritis, Sarcoidosis, Acute, uncomplicated Malaria
How Eroqeen Syrup works
Eroqeen Syrup inhibits the action of heme polymerase in malarial trophozoites, preventing the conversion of heme to hemazoin. Plasmodium species continue to accumulate toxic heme, killing the parasite.
Eroqeen Syrup passively diffuses through cell membranes and into endosomes, lysosomes, and Golgi vesicles; where it becomes protonated, trapping the chloroquine in the organelle and raising the surrounding pH. The raised pH in endosomes, prevent virus particles from utilizing their activity for fusion and entry into the cell.
Eroqeen Syrup does not affect the level of ACE2 expression on cell surfaces, but inhibits terminal glycosylation of ACE2, the receptor that SARS-CoV and SARS-CoV-2 target for cell entry. ACE2 that is not in the glycosylated state may less efficiently interact with the SARS-CoV-2 spike protein, further inhibiting viral entry.
Dosage
Eroqeen Syrup dosage
Acute malaria:
- Adult: As base: Initially, 600 mg followed by 300 mg 6-8 hr later on day 1. On days 2 and 3, single doses of 300 mg/day.
- Child: Initially, 10 mg base/kg (max 600 mg base) followed by 5 mg base/kg (max 300 mg base) after 6 hrs. Single doses of 5 mg base/kg on days 2 and 3.
Hepatic amoebiasis:
- Adult: As base: 600 mg daily for 2 days then 300 mg daily for 2 or 3 wk given with emetine or dehydroemetine.
- Child: 6 mg/kg daily. Max dose: 300 mg daily.
Rheumatoid arthritis:
- Adult: As base: 150 mg daily. Max: 2.5 mg/kg daily. Discontinue treatment if there is no improvement after 6 mth.

Side Effects
Retinopathy, hair loss, photosensitivity, tinnitus, myopathy (long-term therapy). Psychosis, seizures, leucopenia and rarely aplastic anaemia, hepatitis, GI upsets, dizziness, hypokalaemia, headache, pruritus, urticaria, difficulty in visual accommodation.
The most serious toxic hazard of prolonged therapy with doses is the occasional development of irreversible retinal damage. For this reason considerable caution is needed in the use of choroquine for long-term high dosage therapy and such use should only be considered when no other drug is available. Defects in visual accommodation may occur on first taking choloquine and patients should be warned regarding driving or operating machinery.
Toxicity
Patients experiencing an overdose may present with headache, drowsiness, visual disturbances, nausea, vomiting, cardiovascular collapse, shock, convulsions, respiratory arrest, cardiac arrest, and hypokalemia. Overdose should be managed with symptomatic and supportive treatment which may include prompt emesis, gastric lavage, and activated charcoal.
Precaution
Psoriasis, diseases of the haematopoietic or CNS systems, myasthenia gravis, hepatic or renal impairment, G6PD deficiency, epilepsy, childn. Pregnancy and lactation. Slow infusion is used upon IV admin to prevent cardiotoxicity.
Interaction
Concomitant therapy with phenylbutazone predisposes to dermatitis, antagonises effect of neostigmine and pyridostigmine, reduces bioavailability of ampicillin. Cimetidine inhibits metabolism of chloroquine raising plasma levels.
Food Interaction
- Take with food. Food reduces irritation and increases bioavailability.
[Moderate] GENERALLY AVOID: Theoretically, grapefruit and grapefruit juice may increase the plasma concentrations of hydroxychloroquine or chloroquine and the risk of toxicities such as QT interval prolongation and ventricular arrhythmias.
The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruit.
Following coadministration with cimetidine, a weak to moderate CYP450 3A4 inhibitor, a 2-fold increase in chloroquine exposure occurred.
Since chloroquine and hydroxychloroquine have similar structures and metabolic elimination pathways, a similar interaction may be observed with hydroxychloroquine.
In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands.
Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.
Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.
MANAGEMENT: Although clinical data are lacking, it may be advisable to avoid the consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract during hydroxychloroquine or chloroquine therapy.
