If the claims of a patent read on a pharmaceutical product, the product infringes. If the claims require a component A, and a product does not contain A but instead uses a different component B, then there is no infringement of that claim. As it is always better to get your advice using the specific facts of your situation, you should contact a patent attorney for an expert opinion.
