Question: Why is drug monitoring essential for aminoglycosides?

Answer: Monitoring aminoglycosides prevents nephrotoxicity and ototoxicity due to their narrow therapeutic index.

Question: Discuss the impact of genetic polymorphism on drug therapy.

Answer: Genetic polymorphisms in drug-metabolizing enzymes can alter drug efficacy and safety.

Question: What is a pharmacokinetic drug interaction?

Answer: A pharmacokinetic drug interaction occurs when one drug affects the absorption, distribution, metabolism, or excretion of another drug.

Question: How is drug accumulation calculated?

Answer: Drug accumulation is calculated using the formula Accumulation Factor = 1 / (1 – e^(-ke × dosing interval)).

Pharmacovigilance

Question: Define pharmacovigilance.

Answer: Pharmacovigilance is the science of detecting, assessing, and preventing adverse drug reactions (ADRs).

Question: What are the common methods for reporting ADRs?

Answer: ADRs are reported through spontaneous reporting systems, prescription event monitoring, and electronic health records.

Question: Why is pharmacovigilance important in clinical practice?

Answer: Pharmacovigilance ensures drug safety by identifying risks and minimizing harm to patients.

Question: What are the different types of ADRs?

Answer: ADRs are classified as Type A (predictable) and Type B (unpredictable).

Question: Explain the role of the WHO in pharmacovigilance.

Answer: The WHO coordinates global pharmacovigilance efforts, providing guidelines and maintaining the ADR database.

Question: What is a signal in pharmacovigilance?

Answer: A signal is information that suggests a new or known drug-related risk requiring further investigation.

Question: How does spontaneous reporting help in pharmacovigilance?

Answer: Spontaneous reporting helps identify rare and unexpected ADRs, enhancing drug safety.

Question: What are the challenges in pharmacovigilance?

Answer: Challenges include underreporting, data quality issues, and limited resources for monitoring.

Question: How are ADRs assessed for causality?

Answer: ADRs are assessed using algorithms like Naranjo’s scale or WHO-UMC criteria.

Question: What is the role of regulatory agencies in pharmacovigilance?

Answer: Regulatory agencies monitor ADRs, enforce reporting requirements, and ensure drug safety compliance.

Question: What is the importance of post-marketing surveillance?

Answer: Post-marketing surveillance identifies long-term and rare ADRs that clinical trials might miss.

Question: Define risk management plan (RMP).

Answer: An RMP outlines strategies to identify, assess, and minimize drug risks throughout its lifecycle.

Question: How is data mining used in pharmacovigilance?

Answer: Data mining identifies patterns and signals in large pharmacovigilance databases to detect potential ADRs.

Question: What are black box warnings?

Answer: Black box warnings highlight serious or life-threatening ADRs associated with a drug.

Question: What is the Yellow Card Scheme?

Answer: The Yellow Card Scheme is the UK’s system for reporting ADRs and drug safety concerns.

Question: Discuss the importance of patient education in pharmacovigilance.

Answer: Patient education promotes awareness of ADRs and encourages timely reporting, enhancing drug safety.

Question: What is the role of healthcare professionals in pharmacovigilance?

Answer: Healthcare professionals report ADRs, educate patients, and ensure safe drug use.

Question: Define adverse drug event (ADE).

Answer: An ADE is any undesirable occurrence associated with drug use, whether or not it is causally related.

Question: What is the difference between ADR and side effect?

Answer: An ADR is harmful and unintended, while a side effect can be any secondary effect, whether harmful or beneficial.

Clinical Pharmacy

Question: What is the role of a clinical pharmacist?

Answer: A clinical pharmacist optimizes drug therapy, ensures patient safety, and provides medication-related education.

Question: Define pharmaceutical care.

Answer: Pharmaceutical care involves the responsible provision of drug therapy to achieve specific health outcomes.
