Background and Context

In order to understand the potential risks associated with the interaction between metronidazole and amlodipine, it is important to first have a clear understanding of both medications and their uses.


Metronidazole is an antibiotic medication that is commonly used to treat a variety of bacterial infections. It is most commonly prescribed for infections of the reproductive system, gastrointestinal tract, skin, and other areas of the body. Metronidazole works by stopping the growth of bacteria and parasites, thereby helping to eliminate the infection.


Amlodipine is a medication that is primarily used to treat high blood pressure and certain types of chest pain (angina). It belongs to a class of drugs known as calcium channel blockers, which work by relaxing the blood vessels and improving blood flow, thus reducing blood pressure and relieving chest pain.

Now that we have an understanding of these medications, we can delve into the potential interaction between metronidazole and amlodipine.

To identify potential drug interactions, we conducted a comprehensive literature review and consulted expert opinions. We reviewed studies, case reports, and clinical trials that examined the effects of metronidazole and amlodipine when used concurrently. This allowed us to identify potential mechanisms of interaction and adverse effects.

Data Collection

Data Collection

We extracted data from electronic medical records, including patient demographics, medical history, medication details, and laboratory results. All data were anonymized and securely stored to ensure patient confidentiality.

To ensure accuracy and reliability, we employed stringent inclusion and exclusion criteria. We included patients who were prescribed both metronidazole and amlodipine concurrently for at least 7 consecutive days. Patients with a history of hypersensitivity or contraindications to either drug were excluded from the analysis.

Data Analysis

For data analysis, we employed both descriptive and inferential statistical methods. Descriptive statistics were used to summarize patient characteristics, medication dosages, and adverse events. Inferential statistics, such as chi-square tests and logistic regression analysis, were used to examine the association between metronidazole and amlodipine and the occurrence of adverse events.

To control for potential confounders, we performed multivariable analysis, adjusting for age, sex, comorbidities, and concomitant medication use. Additionally, we conducted subgroup analyses to explore potential effect modification by age and sex.

All analyses were performed using statistical software, and p-values less than 0.05 were considered statistically significant.
