What is the brand name of citalopram hydrobromide?
Prozac
Celexa
Lexapro
Effexor
The Correct Answer is B
A. Prozac is the proprietary brand name for fluoxetine, a selective serotonin reuptake inhibitor. It is chemically distinct from citalopram due to its specific phenylpropylamine structure and long-acting metabolite norfluoxetine. It is not the brand name for citalopram hydrobromide.
B. Celexa is the brand name for citalopram hydrobromide, a highly selective serotonin reuptake inhibitor. It increases synaptic serotonin levels by inhibiting the presynaptic transporter protein in the central nervous system. This pharmacological action is utilized to treat major depressive disorder.
C. Lexapro is the brand name for escitalopram, which is the pure S-enantiomer of the racemic mixture citalopram. While it shares a similar chemical scaffold, it provides higher potency at the serotonin transporter site. It is a distinct product from Celexa.
D. Effexor is the brand name for venlafaxine, which belongs to the serotonin-norepinephrine reuptake inhibitor class. It inhibits the reuptake of both serotonin and norepinephrine neurotransmitters in a dose-dependent manner. It is not a brand name for the medication citalopram.

Correct Answer is B
Explanation
A. Piperacillin with tazobactam is a parenteral antipseudomonal penicillin combination marketed under the brand Zosyn. It is used for severe systemic infections involving Pseudomonas aeruginosa. It is not the generic composition of the oral medication known as Augmentin.
B. Augmentin is the brand name for amoxicillin with clavulanate potassium. Amoxicillin is a beta-lactam antibiotic that inhibits cell wall synthesis. Clavulanate acts as a beta-lactamase inhibitor, preventing the enzymatic degradation of amoxicillin by resistant bacterial strains.
C. Metronidazole is a nitroimidazole antimicrobial used for anaerobic infections and protozoal diseases. It functions by creating reactive free radicals that disrupt bacterial DNA. It is a single-agent generic medication and is not the active component of Augmentin.
D. Sulfamethoxazole with trimethoprim is a sulfonamide combination marketed under the brand Bactrim or Septra. This drug inhibits two consecutive steps in the bacterial folic acid synthesis pathway. It represents a different pharmacological class than the penicillin-based Augmentin.
