Pharmacology of Drugs Acting on Cardiovascular System Questions
Question 1 of 5
Characteristics of ephedrine include all of the following EXCEPT:
Correct Answer: D
Rationale: The correct answer is D because ephedrine actually increases arterial pressure by stimulating alpha-adrenergic receptors, leading to vasoconstriction. A is incorrect as ephedrine works by directly stimulating adrenergic receptors, not by releasing stored catecholamines. B is correct as ephedrine is indeed a mild CNS stimulant. C is incorrect as tachyphylaxis, or a rapid decrease in response with repeated administration, is not commonly associated with ephedrine.
Question 2 of 5
Which of the following hypnotic benzodiazepines is more likely to cause “hangover” effects such as drowsiness dysphoria and mental or motor depression the following day?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
Indicate an antiseizure drug that is a sodium channel blocker and is used as an adjunctive therapy for partial and generalized seizures:
Correct Answer: B
Rationale: Rationale: 1. Lacosamide is a sodium channel blocker, working by enhancing slow inactivation of voltage-gated sodium channels. 2. It is used as an adjunctive therapy for partial-onset seizures in adults. 3. Lacosamide is also approved for the treatment of generalized seizures in certain patients. 4. Carbamazepine (A) is a sodium channel blocker but is primarily used for focal seizures. 5. Ethosuximide (C) is a T-type calcium channel blocker used for absence seizures. 6. Lamotrigine (D) is a sodium channel blocker but is mainly used for focal and generalized seizures, not as an adjunctive therapy.
Question 4 of 5
Tick narcotic analgesic which is a phenylpiperidine derivative:
Correct Answer: C
Rationale: The correct answer is C: Fentanyl. Fentanyl is a phenylpiperidine derivative due to its specific chemical structure containing a piperidine ring attached to a phenyl group. Codeine (A) is an opioid, but not a phenylpiperidine derivative. Dezocine (B) is a benzomorphan derivative. Buprenorphine (D) is a thebaine derivative. Fentanyl stands out as the only option that fits the phenylpiperidine derivative category.
Question 5 of 5
Tick pirazolone derivative:
Correct Answer: B
Rationale: The correct answer is B: Analgin. Analgin is a pirazolone derivative, specifically metamizole. It is a non-opioid analgesic and antipyretic medication. Methylsalicylate is a salicylate derivative used as a topical pain reliever. Paracetamol is an analgesic and antipyretic drug but not a pirazolone derivative. Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) but not a pirazolone derivative. Therefore, Analgin is the only choice that fits the criteria of being a pirazolone derivative.
