Valued customer; On this selected Product size, Canada Drugs Direct is currently faced with regional restrictions on the export of pharmaceuticals related to the ongoing COVID-19 pandemic. As a result, we have been forced to put a temporary maximum order limit of a 30-day supply on this product. To do our best to support you during this challenging time Canada Drugs Direct will be offering the following to customers placing medication orders:

  • An automatic free-year term upgrade on our standard $6.99 flat rate for shipping of purchases. You’ll now pay the same $6.99 rate, but you’ll be getting a YEAR of free shipping for it.
  • Frequent and timely follow-up calls from our Patient Support Team to ensure your refills are processed much earlier than they would be normally, and you do not run out of needed medication

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


This medicine is a calcium channel blocker used to treat high blood pressure. Calcium is needed for blood vessel contraction. By blocking calcium, this medicine causes the blood vessels to relax and widen. This can help to lower blood pressure. Lowering high blood pressure helps to prevent strokes, heart attacks, and kidney problems. Diltiazem may also be used to treat chest pain (angina) and irregular heartbeats.
