Is chloroquine phosphate oxytetracycline?

Chloroquine phosphate is primarily used to treat malaria caused by chloroquine-sensitive strains, including Plasmodium falciparum (malignant tertian malaria), P. vivax (tertian malaria), and P. malariae (quartan malaria). It is also indicated for extraintestinal amebiasis and possesses anti-rheumatic properties. Research has shown that chloroquine phosphate effectively inhibits infection by the novel coronavirus (2019-nCoV) responsible for the outbreak in Wuhan at the cellular level. So—is chloroquine phosphate the same as oxytetracycline? Below, we address this question.

Is chloroquine phosphate the same as oxytetracycline?

No, chloroquine phosphate is not oxytetracycline. Chloroquine phosphate is an antimalarial agent primarily used to treat autoimmune disorders such as malignant tertian malaria, tertian malaria, and quartan malaria. In contrast, oxytetracycline is an anti-inflammatory antibiotic effective against infections caused by susceptible bacteria; it exhibits broad-spectrum antimicrobial activity and functions as a bacteriostatic—not bactericidal—agent. Thus, these are two distinct medications. Additionally, chloroquine phosphate inhibits protozoal DNA synthesis and RNA transcription, thereby reducing nucleic acid synthesis and interfering with protozoal replication. It is also used to treat extraintestinal amebiasis, connective tissue diseases, and photosensitivity disorders such as solar erythema. Furthermore, it demonstrates anti-rheumatic and anti-SARS-CoV-2 effects.

Additional Information: Side Effects of Chloroquine Phosphate

1. After oral administration, some patients may experience dizziness, headache, blurred vision, loss of appetite, nausea, vomiting, abdominal pain, diarrhea, pruritus, rash, exfoliative dermatitis, tinnitus, or irritability. However, most adverse reactions are mild and resolve spontaneously upon discontinuation of the drug.

2. When used to treat paragonimiasis, clonorchiasis, or connective tissue diseases at high doses or over prolonged treatment courses, chloroquine phosphate may exert ocular toxicity. The drug is secreted by lacrimal glands and absorbed by the cornea, leading to diffuse white granular deposits on the cornea—reversible upon cessation of therapy.

3. Long-term use may cause mild retinal edema and pigment deposition, resulting in scotoma (blind spots).

The above clarifies whether chloroquine phosphate is the same as oxytetracycline. Additionally, caution should be exercised when prescribing chloroquine phosphate to patients with renal insufficiency, cardiac disease, severe erythema multiforme, psoriasis, pregnancy, or psychiatric disorders.
