What is the dosage of Sulfadoxine and Pyrimethamine in each uncoated tablet of Trafan?

Step 1: Identify the amount of Sulphadoxine per tablet from the label.
$500\ mg/tablet$

Step 2: Standard adult dose of Sulphadoxine for this antimalarial combination.
$1500\ mg$

Step 3: Formula for number of tablets required.
$n = \frac{total\ dose}{dose\ per\ tablet}$

Step 4: Substitute values.
$n = \frac{1500\ mg}{500\ mg/tablet}$

Step 5: Simplify.
$n = 3\ tablets$

Step 6: Verify with Pyrimethamine content.
Pyrimethamine per tablet = $25\ \mathrm{mg}$.
For 3 tablets: $3 \times 25\ mg = 75\ \mathrm{mg}$, which matches the standard adult dose.
