Q

What is the MOA of flumazenil?

A

Completely inhibits the activity at the benzodiazepine receptor site on the GABA/benzodiazepine receptor complex.

Flumazenil does not antagonize the CNS effect of drugs affecting GABA-ergic neurons by means other than the benzo receptors (ethonal, barbiturates, general anesthetics) and does not reverse the effects of opiods

  6. For high doses monitor electrolytes at baseline and at least daily methotrexate levels, UO and ph.
  7. Chest xray- RA
32
Q

The MOA of methotrexate

A

Methotraxate has more than one MOA. To get rid of cancerous cells, it acts as a folate antagonist that works by targeting an enzyme dihydrofolate reductase- an enzyme necessary for folic acid production. Folic acid is a necessary compound for nucleotide synthesis. Therefore its inhibition stops nucleotide formation. Methotraxate rargets actively dividing cells. Therefore, it is effective agaist cancer cells.

In inflammatory conditions, such as psoriasis and RA, methotrexate acts with a different MOA, giver intermittently once a week. It works by inhibiting enzymes involved in purine metabolism, leading to the accumulation of adenosine and its release from cells

Adenosine works by acting on cell surface receptors, suppressing the expression of adhesion molecules on tcells and neutrophils, eventually inhibiting their accumlation in inflammed tissue. Moreover, it lowers the release of cytokines from inflammatory cells. In this way methotrexate acts as an anti-inflammatory drug

33
Q

What should we teach patients about methotrexate?

A
  1. Has a toxic effect on rapidly dividing tissues, esp. bone marrow. It can cause bone marrow tox, hepat tox, and PNEUMONITIS. to monitor for its toxcities, frequent blood counts and liver function testing should be done. Before the first prescription, a chest xray should also be done.
  2. Should be avoided in patients with renal impairment
  3. Avoid NSAIDS- like acetaminophen and asprin
  4. Report new onset symptoms like: blood disorders, mouth ulcers, sore throat, bruising… Liver tox: n/v/abdominal discomfort and dark urine, REsp: SOB
34
Q

What is the black box warning for Lorazepam?

A
  1. Risks from concomitant use with opioids (injeciton,oral)- may cause profound sedation, resp depression, coma and death.
  2. The use of benzos including lorazepam, exposes users to risk of abuse, misuse and addiction which can lead to overdose and death.
  3. Dependance and withdrawal reactions.
35
Q

What pharm class is lorazepam?

37
Q

What is the MOA of lorazepam?

A

Binds to benzodiazepine receptors on the postsynaptic GABA-a Ligand-gated choloride channel neuron at several sites within the central nervous system.
