Q

What is the mechanism of action of Prednisolone (Panafcortelone, Predsolone, Solone)?

A

Corticosteroids regulate gene expression, which results in:

  • Glucocorticoid effects, e.g. gluconeogenesis, proteolysis, lipolysis, suppression of inflammation and immune responses
  • Mineralocorticoid effects, e.g. hypertension, sodium and water retention, potassium loss

Q

What is the mechanism of action of Promethazine (Phenergan)?

A

Reduce the effects of histamine by binding to the H1 receptor and stabilising it in an inactive form

They also have anticholinergic activity and some have alpha-blocking activity

Q

What is the mechanism of action of Methotrexate (Methoblastin)?

A

Inhibits DNA synthesis and cell replication by competitively inhibiting the conversion of folic acid to folinic acid as it resembles the structure of folic acid

It has cytotoxic, immunosuppressive and anti-inflammatory action

Q

What is the mechanism of action of Anakinra (Kineret)?

Q

What is the mechanism of action of Cyproterone acetate (Procur, Androcur)?

A

Competitively inhibits the binding of androgen at androgen receptors

Cyproterone (a steroidal anti-androgen) also has progestogenic effects that result in decreased production of testosterone

Q

What is the mechanism of action of Dexamethasone (Dexmethsone)?

Study These Flashcards
A

Regulates gene expression, which results in mainly glucocorticoid effects, but also some mineralocorticoid effects

Acts as an anti-inflammatory and immunosuppressant, mimicking the effect of cortisol but with 20 to 30 times the potency. It is 4 to 5 times more potent than prednisone

With steroid treatment, it is critical to progressively reduce dosage rather than stop administration abruptly. This is because the adrenal glands significantly reduce steroid production when levels are high (due to treatment) and it takes some weeks to recover from induced adrenal insufficiency

21
Q

What is the mechanism of action of Leuprorelin (Eligard, Lucrin)?

Study These Flashcards
A

GnRH initially stimulates synthesis of FSH and LH, transiently increasing serum testosterone in males or serum oestrogen in females

Continuous administration of GnRH agonists inhibits gonadotrophin production, suppressing ovarian and testicular steroidogenesis and inhibiting the growth of certain hormone-dependent tumours

22
Q

What is the mechanism of action of Tamoxifen (Nolvadex)?

Study These Flashcards
A

Competes with oestrogen for receptor sites in breast tissue (anti-oestrogenic effect) inhibiting tumour growth

Also have oestrogen agonist activity on endometrium, bone and lipids

Suppression of other growth factors and cytokines may occur

23
Q

What is the mechanism of action of Letrozole (Femara)?

Study These Flashcards
A

Aromatase enzymes (in fat, liver, muscle and breast tissue of postmenopausal women) convert circulating androstenedione and testosterone to oestriol and oestradiol

Aromatase inhibitors reduce tissue oestrogen concentration

24
Q

What is the mechanism of action of Hydrocortisone (Hysone, Sigmacort)?

Study These Flashcards
A

Regulates gene expression, which results in both glucocorticoid and mineralocorticoid effects

In the kidney, cortisol is a potent agonist of the mineralocorticoid receptor. However, these mineralocorticoid receptors are ‘shielded’ from cortisol by the action of 11β-HSD 2, which converts active cortisol into inactive cortisone. This mechanism ensures that, at physiologic levels, cortisol does not exert mineralocorticoid effects

At high concentrations, however, cortisol can overwhelm the capacity of 11β-HSD 2, leading to stimulation of renal mineralocorticoid receptors
