A

high estrogen and progesterone block GnRH release which block FSH and LH release

block LH reduced androgen production and increase SHBG

inhibit follicle development, ovulation, alter cervical mucus so sperm cant penetrate

25
1st choice for dysmenorrhea
oral contraception (if also want contraception) OR NSAIDS
26
27
Which of the following drugs can be used to induce ovulation in people with endometriosis? A. Letrozole B. Levonorgestrel C. Elagolix D. Leuprolide
A. Letrozole
28
NSAIDs to use for dysmenorrhea
- COX-2 inhibitors: celecoxib - Non-selective- NSAIDs: ibuprofen, naproxen acetaminophen is not as good for analgesic
29
30
when to take NSAIDs for dysmenorrhea
- Take when onset or symptoms or menses and continue on regular schedule for 2-3 days
31
NSAIDs inhibit
prostaglandins
32
progestin only contraceptive example to reduce blood loss
- Levonorgestrel intrauterine system (IUD)
33
contraindications for - Levonorgestrel intrauterine system (IUD)
: pregnancy, PID, postpartum endometriosis, uterine malignancies, cervicitis, liver disease
34
best option for endometrosisi
combined hormonal contraceptives
35
progestin only contraceptive in endometriosis
- Injectable medroxyprogesterone acetate or levonorgestrel IUS is more convenient than daily norethindrone
36
when to use opioid analgesics in endometrosis
if cant used NSAIDS can be addicting
37
androgen agonist
danazol
38
androgen agonist for endometriosis when not to use
danazol - Endometriomas >1cm don’t respond well
39
adverse effects of androgen agonists
voice deepening, decrease breast size, increase weight, hirsutism, increase LDL, hot flashes, vaginal dryness
40
GnrH agonist name
elagolix, - - Leuprolide and goserelin
41
GnRH agonist in endometriosis
- As effective as COCs and progestins to manage endometriosis-associated pain - But COCs have less side effects
42
what to do if using GnrH agonist
add back therapy (estrogen and progesterone) bc can cause perimenospauseal sx like hot flashes, bone minders density, libido
43
ovulation induction example drug
letrozole
44
ovulation induction mechanism of action
inhibits aromatase enzyme; so cant convert to estrogen o Reduces estrogen levels so pituitary makes more FSH for follicles
45
antifibrinolytic use and example
tranexamic acid for heavy periods
46
Which of the following drugs acts as an antagonist of leukotriene receptor interactions in target tissues? A. Budesonide B. Montelukast C. Formoterol D. Omalizumab
B. Montelukast
47
asthma defintion
- Inflammation of airways; activate mast cells to release bronchoconstrictors (histamine, leukotriene, prostaglandin) leads to smooth muscle contraction, vasodilation, mucus hypersecretion…
48
inhaled corticosteroids work on which receptor
- Increase b2 adrenergic receptor and antiinflam cytokines, decrease proinflam cytokines
49
how to reduce systemic exposure of inhaled corticosteroids on body
reduce systemic exposure via first past effect or prodrug that activated by lungs o Ciclesonide is inert until activated by lung esterase’s o Budesonide is metabolized by CYP3A4; bioavailability 10%
50
2 inhaled corticosteroids
ciclesonide budesonide
51
use inhaled cortcosteroids with
bronchodilator
52
side effects of inhaled corticosteroids
: sore throat, dysphonia, oral thrush, decreased growth rate in kids, osteoperosis, glaucoma
53
inhaled beta2 agonist pathway
- Activate beta2 receptor  activate adenylyl cyclase  increase cAMP  activate PKA  muscle relaxation (via phosphorylation of contractile proteins) --> bronchodilation
54
side effects of inhaled beta2agonist
Tachycardia, palpitations, nervousness, tremor, hypokalemia, restlessness, dizziness, headache, nausea
55
short acting vs long acting inhaled beta2 agonist
short: salbutamol long: salmeterol and formoterol
56
salbutamal (beta 2 agonist use)
use with daily inhaled cortocpsteroid
57
exercise induced asthma then use
beta 2 agonist before (i.e salbutamol)
58
anticholinergic bind
M3 muscarinic receptors to block cholinergic stimulation from vagus nerve - Blocks calcium increase and prevents bronchoconstriction
59
anticholinergic examples long and short acting
short: ipatropium long: tiotropium
60
use anticholinergic as
use as add on therapy to beta2-agonist for exacerbations or as an alternative if susceptible to tachycardia
61
leukotriene pathway for asthma -
- Asthma trigger (i.e. cold, antigens, exercise) release arachidonic acid which then is converted into leukotriene (LTA4)  LTB4 and LTC4  LTC4 into LTD4 and LTE4 at target tissues (ie.. smooth muscle)
62
example of leukotriene antagonist
montelukast
63
montelukast use (leukotriene antagonist)
second line option add on o Inhaled corticosteroid+ long acting beta agonist combo is better o Might be more useful if have concomitant rhinitis
64
boxed warning for leukotriene receptor antagonist (montelukast)
neuropsychiatric effects i.e. depression, aggression, hallucinations, suicidal
65
biologics use
severe and uncontrolled asthma
66
types of biologics
IgE (omalizumab) IL5 (eosinophil) (mepolizumab) IL4/IL13 (dupilumab)
67
IGE neutralizing antibodies (biologic) exam and use
- Omalizumab - For kids >6 yoa with IgE mediated asthma
68
interuleukin5 inhibitor (biologic) example and use
- Mepolizumab - IL5 for eosinophils in allergies - For kids >6 with eosinophilic asthma (via blood cell count)
69
IL4R neutralizing antibody (biologic) example and use
dupilumab - IL4 and IL13 are inflammatory cytokines - For kids >6 with severe asthma or atopic dermatitis
70
controller and reliever in asthma
 Step 1-5  Controller: Low dose ICS- fomoteral as needed  Reliver: ICS- fomoteral, short acting beta2 agonist (as alternative)
71
asthma in pregnancy ; what to use and what not to use
- If uncontrolled can cause preterm birth, congenital anomalies, pre-eclampsia… - Need good control - Use inhaled corticosteroids and beta2-adrenergic receptor agonist same as above; safe - Don’t use biologics
