Approved in Canada

When you buy prescription medications from a Canadian pharmacy, you want to know that they’re safe.

To ensure prescription drug safety for each and every drug sold – from Eliquis to the Trelegy Elipta – Canada’s FDA equivalent has an extensive drug approval process.

For a company to distribute, sell, and market a prescription drug in Canada, they need to make sure their medication goes through the entire Canadian Drug Review and Approval Process.

It takes multiple years to confirm compliance with the Canada version of the FDA, Canada’s Food and Drugs Act, Health Canada guidelines, and Food and Drug Regulations.

How does a drug get approved in Canada? Let’s start at the beginning.

How Are Drugs Approved in Canada with Canada’s Version of the FDA?

You may be familiar with the Food and Drug Administration (FDA), or the American government agency that oversees the safety of various food and drug products in the United States.

What is the equivalent of the FDA in Canada? (Does Canada have an FDA?)

Not exactly – but its Drug Review and Approval process is very similar. (In fact, the FDA signed an agreement with the Canada FDA equivalent, the Canadian Food Inspection Agency (CFIA) as well as the Department of Health Canada, which recognized each others’ food and drug safety systems as comparable.)

The drug approval process in Canada is overseen by the Health Products and Food Branch of Health Canada (HPFB) – a national authority and Canada FDA equivalent that monitors the quality of therapies, drugs, and health products in the Canadian pharmaceutical marketplace.

This office’s job is to make sure all prescription drugs reaching the market are safe, effective, and reliable.

At the end of a lengthy review process, a health product or prescription drug may receive a stamp of approval from the HPFB or the Canada version of the FDA. That doesn’t mean that the drug’s forever in the clear, though. Instead, the HPFB will continue to monitor the safety and effectiveness of the drug over time.

Before approval occurs, drugs need to make it through a multi-stage, increasingly-difficult process. This gauntlet begins with preclinical trials.

The Preclinical Trial Process for Drugs Sold in Canada

There’s an easy way to distinguish between the major phases of drug approval in Canada – the preclinical and clinical phases.

Preclinical trials involve testing a drug’s safety in animal models.

Clinical trials test drug safety and efficacy in human volunteers.

Researchers might administer a drug in varying concentrations to a wide range of species in a preclinical trial to learn more about how that drug works.

The first preclinical studies may involve in vitro trials, or trials that occur outside a living organism. This most often involves experiments with cells in Petri dishes.

Then, once a drug’s safety seems promising and the Canada FDA equivalent gives its approval, the researchers might move to in vivo trials involving animals such as mice, fish, birds, or monkeys.

The primary aim of preclinical trials is usually more knowledge about toxicity and general safety. Preclinical trials are generally looking for:

  • Initial evidence supporting the performance of the drug
  • As much knowledge as possible about any toxic effects a drug may have
  • Information about the safest possible starting dose for a human volunteer

If the researchers can glean data from these preclinical studies that look promising – e.g., that the medication seems effective and non-toxic – the person sponsoring the drug can file an application with Health Canada or the Canada version of the FDA for permission to go onto the next step: Clinical trials.

This application must include a summary of preclinical test results, plans for production of the drug, proposed dosage strategies, and extensive information about the background and affiliations of the people conducting the study going forward.

How the Clinical Trial Process for Drug Approval Starts

Clinical trials – necessarily coming only after preclinical trials have deemed a drug not toxic – involve human volunteers. Clinical trials are costly, regulated, and difficult to manage.

Just as preclinical trials had a specific purpose, so do clinical trials.

Clinical trials seek to demonstrate a drug’s safety and efficacy in humans – and the most helpful dose for human patients to receive the best therapeutic benefit.

In other words, if you’ve ever wondered why you take 10 milligrams of atorvastatin or 150 milligrams of Wellbutrin, it’s because researchers honed in on that amount through a clinical trial process.

To start the lengthy clinical trial process, the HPFB must be on board. After reviewing a company’s clinical trial application, the HPFB will provide authorization to initiate a clinical trial.

The company making or sponsoring the drug will typically have to partner with a CRO, or clinical research organization, to help them advertise to, inform, obtain consent from, and manage tens to thousands of human subjects.

The researchers have a hefty task before them to complete a clinical trial properly. They will need to create a controlled environment, find a safe and scalable way to administer the drug, and have a reliable system for measuring the drug’s effect.

This requires a tremendous amount of effort, coordination, and capital.

And clinical trials are far from a one-and-done thing.

The Four Phases of Clinical Trials for Drug Approval

A drug manufacturer will need to move their drug through four different phases of clinical trials to get to the next stage of drug approval from the Canada FDA equivalent. These include:

  • Phase 1: Safety. In this phase, the investigators will test their drug on a tiny group of people with no known diseases or disorders. In addition, this phase aims to find a safe dose or range of doses and see whether the drug produces any adverse side effects.
  • Phase 2: Efficacy. In this phase, the investigators will find a larger group of volunteers who have the disease the drug is targeting. (There will usually be several hundred subjects involved.) This phase aims to determine how effective the drug is against the target pathology and to collect more information about drug safety.
  • Phase 3: Confirmation. Now, if the results from the Phase 2 trials are promising, the investigators would find thousands of patients with the target disease or disorder to volunteer for a much wider-scale study. In addition, this phase would seek to confirm the drug’s efficacy, continue to get data regarding side effects, and compare the drug to others on the market.
  • Phase 4: Long-term monitoring. This part of clinical trials technically occurs after the drug has been approved, so several regulatory steps happen between these phases.

After the drug is already in the Canadian marketplace, the Canada equivalent of the FDA continues to monitor the long-term benefits it provides, any risks that become apparent, more dosage information, and any other data that can be gleaned from the widespread use of the approved drug.

Canada Drug Approval Timeline: What Happens After Clinical Trials?

Suppose the data from the clinical trials demonstrates that the benefits of the drug are reliable and outweigh any associated risks. In that case, the drug manufacturer or sponsor can file another document – a New Drug Submission, or NDS – with the HPFB.

The NDS, much like the application filed to start clinical trials, must contain a whole host of information about the drug, from safety information right down to proposed packaging mockups.

Once the HPFB has all of the information, a committee will review everything known about the drug. Then, if the HPFB needs to pull in external consultants, such as scientists from outside, unbiased organizations, they will.

The HPFB will also look very carefully at the much-condensed amount of information that the drug manufacturer or sponsor proposes giving to healthcare providers and patients – e.g., the information on the label, or the information that your doctor tells you before recommending a drug.

At this point, the HPFB (as the Canada version of the FDA) is looking at the drug and testing it as a marketable therapeutic option. First, it wants to be entirely sure that the drug is safe and reliable, but that isn’t all.

Before allowing the drug to move forward, the HPFB wants to ensure that informed consent regarding how the drug works and all relevant side effects is possible.

In other words, the HPFB is thinking about patients like you and how confident you can be in the drug’s efficacy and safety at this time.

How Long Does the Canada Prescription Drug Approval Process Take?

As you can probably imagine, these various steps for the approval Canadian prescription drugs take a lot of time. As a result, each stage we’ve mentioned thus far is lengthy.

Between first researching and making a drug, preclinical trials, clinical trials, and a healthy amount of review in between each stage, getting a drug approved usually takes between eight and fifteen years.

The last stage, the final review that the HPFB or the Canada equivalent of the FDA performs before allowing the drug on the market, takes six months and two years.

If the drug passes this review, the HPFB will approve the drug for Canadian markets. The drug will receive a Drug Identification Number, and the manufacturer or sponsor will receive a Notice of Compliance.

If this doesn’t happen, the drug’s sponsor may be able to resubmit their application with more supporting data.

Once a Drug is Approved in Canada, is There Any Further Oversight?

Very much so.

Assuming no red flags have been identified, the drug is set to go to market. Then (finally!) the distributor is able to offer it, physicians are able to prescribe it, and patients can purchase it.

But that isn’t the end of Health Canada’s oversight.

As the Canada equivalent of the FDA, Health Canada must continue to oversee the approved Canadian drug’s quality.

After the HPFB approves the drug, Health Canada may decide to test batches of the medication either as the drug ramps up production or even after it’s on the market. If there’s ever any question regarding the drug’s quality, efficacy, or safety, the HPFB has the power to issue a Notice of Noncompliance. This will trigger a recall of that drug from the Canadian market.

That’s not all.

Suppose the companies distributing the drugs to the Canadian markets hear reports about serious side effects or reports indicating the medication doesn’t do what it’s marketed for. In that case, the distributor must notify the HPFB.

Fact: Canadian Pharmaceutical Drugs Undergo Thorough Safety Testing Before Approval

For a drug to go from initial creation to full approval for the Canadian marketplace, it has to undergo extensive tests and trials overseen by the Canada version of the FDA.

For those counting: There are at least seven significant steps in the approval process – including five distinct trial phases and two periods of intense application and review.

The prescription drug approval process in Canada is arduous and exacting by design.
