Quiz on antiarrhythmic drugs: class 2

A company discovers a significant manufacturing deviation during the production of a beta-blocker API that could potentially impact product quality and patient safety. Which of the following is the most appropriate initial regulatory action? *

A 45-year-old female with a history of Wolff-Parkinson-White syndrome experiences a rapid, wide-complex tachycardia that is poorly tolerated. She is hemodynamically unstable. Which of the following medications is *most likely* to be effective and safe in this emergent scenario? *

According to the principles of pharmacovigilance, what is the primary purpose of post-market surveillance for a beta-blocker that has received marketing authorization? *

What is the primary mechanism by which beta-blockers reduce heart rate in the context of supraventricular tachycardias? *

A 65-year-old male presents with symptoms of exertional angina and has a history of hypertension. An ECG reveals sinus rhythm with occasional premature ventricular contractions (PVCs). He is prescribed atenolol 50 mg daily for his angina and hypertension. He reports that the PVCs have significantly decreased since starting the medication. What class of antiarrhythmic activity do beta-blockers primarily exhibit in managing ventricular arrhythmias like PVCs? *

A company receives a Suspected Unexpected Serious Adverse Reaction (SUSAR) report for a beta-blocker during a Phase III clinical trial. What is the typical regulatory timeframe for reporting this SUSAR to regulatory authorities (e.g., FDA, EMA)? *

A 60-year-old male with a history of myocardial infarction 5 years ago and stable angina is prescribed metoprolol succinate 100 mg daily for secondary prevention and rate control. He is also taking aspirin, clopidogrel, and lisinopril. He develops a new cough that is non-productive and bothersome, especially at night. His blood pressure is 130/80 mmHg and heart rate is 65 bpm. Which of the following is the most likely cause of his cough? *

A 50-year-old male with a history of idiopathic dilated cardiomyopathy (EF 30%) and persistent atrial fibrillation is on amiodarone for rhythm control. He develops worsening fatigue and dyspnea. His ECG shows atrial fibrillation with a ventricular rate of 110 bpm. He is currently taking lisinopril, furosemide, and amiodarone. Which of the following beta-blockers could be cautiously added to improve his heart rate control and potentially cardiac function, considering his underlying cardiomyopathy and current medications? *

During the development of a new beta-blocker, a company identifies a potential drug-drug interaction with a commonly prescribed anticoagulant. According to regulatory expectations, what is the most appropriate action to take during Phase II clinical trials? *

Which of the following regulatory bodies is primarily responsible for the approval of new antiarrhythmic drugs, including beta-blockers, in the United States? *

A 72-year-old male with a history of stable coronary artery disease and well-controlled hypertension presents with new-onset atrial fibrillation with a ventricular rate averaging 140 bpm. He denies chest pain, dyspnea, or syncope. His ejection fraction is 50%. He is currently taking aspirin, atorvastatin, and lisinopril. The physician decides to initiate intravenous rate control. Which of the following beta-blockers is generally *contraindicated* in patients with decompensated heart failure or severe bradycardia? *

A 68-year-old male with a history of hypertension and hyperlipidemia presents to the emergency department with palpitations, shortness of breath, and dizziness. His heart rate is 180 bpm, irregular, and his blood pressure is 100/60 mmHg. An ECG confirms new-onset atrial fibrillation with rapid ventricular response. He has no history of asthma or significant bradycardia. Which of the following beta-blockers would be the most appropriate initial choice to control his heart rate? *

According to ICH E6(R2) Good Clinical Practice (GCP) guidelines, what is the primary responsibility of the sponsor regarding the safety monitoring of a clinical trial involving a Class 2 antiarrhythmic drug? *

A pharmaceutical company is developing a new beta-blocker for the treatment of atrial fibrillation. What is the typical regulatory pathway for seeking marketing authorization in the European Union? *

A 70-year-old male with persistent atrial fibrillation is being managed with rate control. He has a history of mild renal insufficiency (creatinine 1.5 mg/dL). He is currently taking carvedilol 25 mg BID. He reports occasional dizziness and fatigue. His heart rate is consistently between 70-80 bpm. Which of the following is a potential adverse effect of carvedilol that could contribute to his symptoms? *

A 75-year-old female with a history of hypertension and type 2 diabetes presents with a syncopal episode. Her ECG reveals sinus rhythm at 55 bpm with occasional premature atrial complexes. She is currently taking amlodipine 10 mg daily and hydrochlorothiazide 25 mg daily. Her physician is considering adding a beta-blocker to help manage her hypertension and potentially prevent future arrhythmias. Which of the following beta-blockers would be *least* appropriate to initiate in this patient due to her current heart rate and history of syncope? *

A company is seeking approval for a generic version of a beta-blocker. Which regulatory pathway would they typically follow in the United States? *

A 55-year-old female with a history of paroxysmal supraventricular tachycardia (PSVT) is experiencing recurrent episodes despite taking oral metoprolol succinate 50 mg daily. She reports that the episodes are often triggered by stress and caffeine. Her last episode required IV adenosine and a brief hospitalization.
