Regulatory Status

Health Canada approval process

The approval process for diltiazem under Health Canada involves rigorous evaluation of the drug's safety and efficacy. Initially, pharmaceutical manufacturers submit a New Drug Submission (NDS) that includes comprehensive clinical trial data. Health Canada then reviews this data, ensuring that the benefits outweigh any potential risks. This thorough process is crucial to guarantee that only safe medications are available in Canadian pharmacies.

Once approved, diltiazem is classified as a prescription-only medication, meaning it is accessible only with a valid prescription. This restriction is in place to safeguard patient health, ensuring they receive appropriate medical guidance when using the drug.

DIN number relevance

The Drug Identification Number (DIN) assigned to diltiazem is vital for ensuring medication safety. This number uniquely identifies the drug, allowing healthcare providers and patients to verify its authenticity. Whenever diltiazem is dispensed, patients can check the DIN on the label to confirm they’ve received the correct medication.

Patients can also use the DIN to research potential side effects or drug interactions. It's a straightforward way to bolster patient safety and promote informed decision-making.
