D Correct answer
Explanation

A signal in pharmacovigilance refers to any information that suggests a possible causal relationship between a medicine and an ADR. It can include an increase in the number of ADR reports, a cluster of ADRs with a similar pattern, or a change in the safety profile of a medicine over time.

Multiple choice

Which of the following is a type of ADR that is caused by an interaction between two or more medicines?

  1. Type A ADR

  2. Type B ADR

  3. Type C ADR

  4. Type D ADR
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Type D ADRs are caused by an interaction between two or more medicines, resulting in an adverse reaction that is not predictable based on the individual properties of the medicines involved.

Multiple choice

Which of the following is an example of a proactive pharmacovigilance activity?

  1. Monitoring ADR reports

  2. Conducting clinical trials

  3. Developing risk management plans

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Developing risk management plans is an example of a proactive pharmacovigilance activity, as it aims to identify and assess risks associated with a medicine and develop strategies to minimize or eliminate those risks before the medicine is marketed.

Multiple choice

Which of the following is an example of a reactive pharmacovigilance activity?

  1. Monitoring ADR reports

  2. Conducting clinical trials

  3. Developing risk management plans

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Monitoring ADR reports is an example of a reactive pharmacovigilance activity, as it involves responding to ADRs that have already occurred.

Multiple choice

Which of the following is a type of ADR that is caused by an overdose of a medicine?

  1. Type A ADR

  2. Type B ADR

  3. Type C ADR

  4. Type D ADR
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Type A ADRs are caused by an overdose of a medicine or by an exaggerated pharmacological effect of the medicine.

  1. Hepatotoxicity study

  2. Neurotoxicity study

  3. Carcinogenicity study

  4. Teratology study
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hepatotoxicity studies evaluate the potential of a drug to cause liver damage.

Multiple choice

Which of the following is a bronchodilator that works by relaxing the smooth muscles of the airways?

  1. Salmeterol

  2. Ipratropium bromide

  3. Montelukast

  4. Cromolyn sodium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Salmeterol is a long-acting beta2-agonist bronchodilator that works by relaxing the smooth muscles of the airways, thereby opening up the airways and making it easier to breathe.

Multiple choice

Which of the following is an anti-inflammatory drug used to treat asthma and chronic obstructive pulmonary disease (COPD)?

  1. Budesonide

  2. Formoterol

  3. Guaifenesin

  4. Phenylephrine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Budesonide is a corticosteroid that works by reducing inflammation in the airways, thereby helping to improve airflow and reduce symptoms such as wheezing, coughing, and shortness of breath.

Multiple choice

Which of the following is an anti-tussive drug used to suppress coughs?

  1. Dextromethorphan

  2. Guaifenesin

  3. Salmeterol

  4. Cromolyn sodium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dextromethorphan is an anti-tussive drug that works by suppressing the cough reflex in the brain, thereby reducing the frequency and severity of coughs.

Multiple choice
