Answer 3

Drug Class: Antimicrobial
Category: transpeptidase (penicillin-binding protein)
Example: ampicillin
Used in combination with cavulanic acid to protect against destruction of Beta-lactamase
(H. influenzae, H. Pylori, E. coli, Listeria, Proteus, Salmonella, Shigella, and other enterococci)

Inhibits protein synthesis by blocking translocation (macro-slidessss)

Question 8

-azine

Answer 8

Drug Class: CNS
Category: Typical Antipsychotic

Blocks dopamine D2 receptor (increases cAMP)
(Schizophrenia, psychosis, bipolar, delirium, Tourette syndrome, huntington, OCD)

Question 9

-barbital

Answer 9

Drug Class: CNS
Category: barbiturate
Example: phenobarbital

Facilitate GABA-A action by increasing duration of Cl− channel opening, thus decreasing neuron firing (sedative for anxiety, seizures, insomnia)

Question 10

• ipramine

- triptyline

Answer 10

Answer 12

Drug Class: CNS
Category: 5-Ht agonist
Example: Sumatriptan

Inhibits trigeminal nerve activation (prevents vasoactive peptide release-> induce vasoconstriction)
Used for acute migraine/cluster headaches

Question 13

• zepam

- zolam

Answer 13

Drug Class: CNS
Category: Benzodiazepine
Example: Diazepam, Alprazolam

Facilitate GABA-A action by increasing frequency of Cl- channel opening (just like Barbiturates)
Used commonly for alcohol withdrawal; anxiety, seizures, eclampsia(pregnant woman-seizures)
