Results: Total 185 drug advertisements were evaluated. Among them, most of them 66.40% were promoting single drug formulation. Antimicrobials 21.6% were the most commonly promoted group. Only 12.4% followed all the criteria as led down by WHO. Most of the drug advertisements have the brand name written with approved generic name, dose, manufacture name and dosage form.
