It’s not quite that simple. You also need to consider the Federal schedule of product. If the product is a Narcotic or controlled drug, advertising to the general public is prohibited (even if the ad contains nothing more than the stylized product name). For other products, yes, advertising is possible within the restrictions that relate to the product’s Federal schedule. For example, advertising for a product in the “Prescription” schedule would be limited to name, price, and quantity as per C.01.044 of the Food and Drug Regulations.
Note that even a drug for the treatment of a schedule A disease can technically be promoted to the general public (as long as it’s not a narcotic or controlled drug), you simply can’t convey (or link to or allude to) the therapeutic use
