Matacin

Description

Matacin contains a fixed-dose combination of Sulfadoxine and Pyrimethamine, widely used in the prevention and treatment of Plasmodium falciparum malaria, including resistant strains. Sulfadoxine works by inhibiting dihydropteroate synthase in the folate synthesis pathway of the malaria parasite, while Pyrimethamine inhibits dihydrofolate reductase (DHFR). Together, they block folate metabolism, an essential process for parasite growth and replication.

Primary Uses

• Prevention and treatment of Plasmodium falciparum malaria.

• Can be used as a second-line therapy in chloroquine-resistant malaria.

• Occasionally prescribed as prophylaxis in high-risk areas (under medical guidance only).

Indications

• Acute uncomplicated falciparum malaria.

• Preventive treatment in endemic regions (not recommended for routine use due to resistance risks).

How to Use

• Take orally, preferably with food to minimize stomach upset.

• Dosage should be strictly according to doctor’s prescription based on weight, age, and malaria resistance pattern in the area.

• Complete the full prescribed course even if symptoms improve early.

Side Effects

Possible side effects include:

• Common: Nausea, vomiting, stomach upset, mild rash.

• Serious: Skin reactions (erythema multiforme, Stevens-Johnson syndrome, Lyell’s syndrome).

• Blood-related: Anemia, agranulocytosis, leukopenia.

• Allergic reactions: Swelling of throat, difficulty breathing (rare but serious).

If severe rash, sore throat, or unexplained fever occurs, stop medication immediately and consult a doctor.

Warnings & Precautions

Pregnancy
Contraindicated – may harm the fetus.

Lactation
Contraindicated – excreted in breast milk, not recommended in breastfeeding mothers.

General Precautions

• Regular blood counts are advised during prolonged therapy to monitor for bone marrow suppression.

• Avoid excessive sun exposure – this drug may cause photosensitivity.

• Use cautiously in patients with:

  • Liver or kidney disease.

  • Blood disorders (e.g., megaloblastic anemia, folate deficiency).

Contraindications

• Known hypersensitivity to sulfonamides or pyrimethamine.

• Severe liver or kidney disease.

• History of blood dyscrasias (e.g., aplastic anemia, agranulocytosis).

• Pregnancy and breastfeeding.

Drug Interactions

• Avoid concurrent use with other sulfa drugs (increases risk of toxicity).

• May interact with antifolic drugs (e.g., methotrexate, trimethoprim).

• Alcohol should be avoided to prevent liver strain.
