male climacteric: decrease level in testosterone
male menopause
2
Q
The Human Sexual Response
A
-Estrous cycle: endocrine stimuli for sexual response to occur.
- Four phases:
1. stimulation- mild increases in sensitivity and beginning stimulation of SNS
2. plateau- stimulation levels off
3. climax- massive SNS stimulation
4. resolution- recovery
3

Sex Hormones
A
estrogens
progesterones

Q
Other Tocolytics: nifedipine
A
Ca channel blocker- drops BP
- supreses contractions
- look out for orthostatic hypotension
7
Q
other tocolytics: Magnesium
A
- watch for magnesium toxicity: decreased DTR, U/O <30 ml/hr, respiratory depression
- calcium gluconate antidote for Mg toxicity (give IV)
- endomethacine- blocks prostaglandin synthesis which suppresses labor.
8

- MS:
13
Q
lupus
A
where the body attacks its own skin and joints
14
Q
Immunosuppresant: Epinephrine
A
- vasopressor (stimulates alpha and beta)
- increase BP and HR
- bronchodilation
- cardiac arrest
- anaphylaxis reaction

18
Q
Marijuana
A
- high THC
- derived from cannabis indica or cannabis sativa families
- amount of THC increased over the past 20 years (5-35%)
19
Q
Hemp (CBD)
A
- low THC, high CBD
- CBD is also echinachea, chocolate, truffles also have CBD
- derived only from cannabis sativa (hemp) family
- around 0.3% THC
20
Q
Inhaled marijuana
A
- onset of psychoactive effects occurs rapidly with peak effects felt at 15-30 minutes
- lasting up to 4 hours
- pulmonary bioavailability varies from 10 to 35 percent of an inhaled dose
- determined by depth of inhalation along with the duration of puffing and breath holding
21
Q
ingested marijuana
A
- delayed onset of psychoactive effect that ranges from 30 min - 3 hours
- clinical effects may last up to 12 hours
- orally administered has low bioavailability (5 - 20 %) because of chemical degradation in gastric acid and substancial first-pass metabolism in liver
- in native users, psychotropic effects occur with 5 - 20 mg of ingested THC
22
Q
Legal THC drugs in U.S.
A
dronabinol/ Marinol- n&v, MS, appetite stimulant
nabilone/ Cesamet- n&v with chemotherapy
23
Q
Cannabis Intoxication s&s
A
- increased HR, BP, or orth. hypotension
- increased RR
- red eye, dry mouth
- nystagmus
- ataxia
- slurred speech
24
Q
Complications with inhalation
A
- acute exacerbations and poor symptom control in patients with asthma
- pneumomediastinum ( air present in space) and pneumothorax suggested by tachypnea, chest pain, and subcutaneous emphysemas caused by deep inhalation w/ breath holding
- rarely, angina and MI
25
Acute cannabis intoxication
- neuro. abnormalies more in children; ataxia, excessive and purposeless motor activity of extremities, lethargy, prolonged coma (life-threatening)
- hyperemesis (bad), behavioral problems (dysphoria or agitation), bronchospasm, pneumothorax
these are medical emergencies, give IV zofran
26
Cannabis Hyperemeis Syndrome
- relieved by hot showers
- acute Tx: IV hydration, antiemetics and benzos.

CBD
* chronic nerve pain
* inflammation
* muscle spasms/ MS symptoms
* reduces cancer induced n&v (CINV)
* may slow cancer growth
* anxiety and terrorism
* insomnia
* acne psoriasis
* withdrawal symptoms
* seizures
28
First CBD approved med. by the U.S.
cannabidiol (Epidiolex)
-used to treat seizures associated with two rare and severe forms of epilepsy, _Lennox-Gastaut syndrome and Dravet syndrome_
29
Epidiolox Pharmacokinetics
* Peak concentration: 1-4 hours
* half life 12 - 32 hours
* highly lipophilic
* highly protein bound
* liver enzyme metabolism
* not expected to contribute to drug-drug interacitons
* excretion = stool and urine
30

willow bark = aspirin
foxglove = digoxin
aloe = burns
vinca = leukemia
