Recreational Drug Use and Sexual Functioning



Recreational Drug Use and Sexual Functioning

Presentation by: Dr. Penny Frohlich
University of Texas at Austin

Recreational Drug Use and Sexual Functioning

Nicotine(Complex impact on hormones & neurotransmitters.)
Short term = interferes with erection
Decreases blood flow to penis
Increases venous outflow from penis
Long term use destroys penile tissues = erectile dysfunction
Passive smoking can have similar impact



Alcohol(Diffuse affects on neurotransmitter processes)
(Affects hippocampus)
Males
Self-report
Increased latency to orgasm (reduced likelihood of premature ejaculation)
Increased likelihood of erectile failure
Alcoholic males: erectile dysfunction (59%); anorgasmic dysfunction (48%); at least one sexual dysfunction (84%) (Mandell et al., 1983)
Laboratory Studies
Inhibits erection (dose dependent)
Increased latency to ejaculation (dose dependent)

Alcohol: FemalesSelf-report:
No change in sexual functioning when intoxicated
Moderate alcohol use (2 per week – 2 per day) associated with lowest rates of sexual dysfunction
Alcoholic females report decrease in sex drive and difficulty achieving orgasm/anorgasmia
Laboratory Studies:
Decreased arousal (Wilson & Lawson, 1976)

Alcohol: FemalesSelf-report:
No change in sexual functioning when intoxicated
Moderate alcohol use (2 per week – 2 per day) associated with lowest rates of sexual dysfunction
Alcoholic females report decrease in sex drive and difficulty achieving orgasm/anorgasmia
Laboratory Studies:
Decreased arousal (Wilson & Lawson, 1976)
Longer latency to orgasm (Malatesta et al, 1982)
Decreased intensity of orgasm (Malatesta et al, 1982)
Increased subjective arousal and orgasm pleasure (Malatesta et al, 1982)

Marijuana(THC (active ingredient) – THC receptors rich in the hippocampus)
lowers testosterone (mixed evidence)
Enhances sexual enjoyment in both men and women (83% and 81% respectively)
Does not affect erection, lubrication, or orgasm.
Increases relaxation, sociability, touch, and comfort.
high doses = sedation and impaired sexual performance.
In animals, decreases sexual activity – general decrease in physical activity.

Amphetamines “speed”(Enhanced release and block reuptake of norepinephrine, and at higher doses, dopamine.)
Can cause vasoconstriction of genital tissue
Sexual Performance:
Increased libido (increased energy)
Erectile failure; prolonged erection (up to 18 hours!)
Anorgasmia; multiple orgasms
Long term use: loss of interest in sex

MDMA “Ecstasy”(Similar to amphetamines, stimulates SNS)
Purported effects:
increased energy
increased endurance
feelings of euphoria
increased sociability
feelings of intimacy
altered visual perception
enhanced libido

MDMA “Ecstasy”Sexual functioning
Subjective ratings: 20 men, 15 women (Zemishlany et al., 2001)
Desire: moderately to profoundly increased
Erection: impaired in 40%
Orgasm: delayed but more intense
Satisfaction: moderately to profoundly increased
Laboratory studies?

MDMA “Ecstasy”Acute side effects/adverse effects (Smith, Larive & Romanelli, 2002):
agitation, anxiety, tachycardia, hypertension
arrhythmias, hyperthermia
Chronic adverse effects:
Toxicity to serotonin system
cardiovascular system
CNS serotonin
Overlap between recreational and fatal dose (Kalant, 2001)

Crystal Methamphetamine
“Crank,” “Crystal,” “Speed”(Increased release of dopamine, adrenaline)
Purported effects:
sense of exhilaration
sharpening of focus
sense of sexual liberation
Sexual Functioning
constricts blood vessels
erectile dysfunction
Risks: similar to amphetamines, risk greater

Physiology of penile erection
Viagra (Sildenafil): Inhibitor of cGMP PDE5
Nitric Oxide & Penile/Clitoral Tumescence
20 SextasyCombining Viagra with ecstasy, “hammerheading”
headache, prolonged erection (priapism)
high risk sexual behavior
long-term heart damage
Viagra with:
crystal methamphetamine
amyl nitrate
any drug that produces erectile dysfunction
Viagra and illegal recreational drugs (40%)

Amyl Nitrate “Poppers”Organic nitrate
Short-acting vasodilator
Increased blood flow to heart and brain
Purported to make sexual organs feel “Herculean”

CocaineInhibits reuptake of dopamine
Potent vasoconstrictor
Increased sexual desire
Arousal:
Men:
low doses – prolonged erection
high doses – erectile failure
Women: reports of both increased and decreased subjective arousal
Delayed or absent orgasm

Opioids: HeroinStimulate opiate receptors (enkephalins (body) and endorphins (brain)) – results in reduction in circulating testosterone
Produce relaxation/sense of well being
Analgesic affect – opiate receptors in female genital tract
Few reports of acute use: lowers drive, delays orgasm
Male Heroin addicts:
loss of drive, erectile dysfunction, orgasmic dysfunction
Withdrawal: increased morning erections, spontaneous ejaculation, slow return of sex drive, erectile and orgasmic dysfunction
Female Heroin addicts:
Decreased drive, increased drive, anorgasmia
Withdrawal: loss of libido

Hallucinogens (LSD, PCP)Purported to be “ultimate sex drug.”
Affects dopamine, serotonin, and with PCP, glutamate.
Sexual pleasure enhanced (all pleasure enhanced – e.g., watching paint dry is equally pleasurable)
Sexual Performance (animal studies):
low doses:
Males: premature ejaculation
Females: normal receptivity
Moderate to high doses – lack of physical coordination precludes any sexual activity.

Psychotropic Drug Use and Sexual Functioning

AntidepressantsMAO inhibitors, SSRIs
Impair all aspects of the sexual response cycle in men and women
Serotonin 5-HT2 receptor implicated
Nephazadone (serzone) SSRI and 5-HT2 antagonist – fewer sexual side effects
Stimulation of the 5-HT2 receptor (peripherally) causes vasoconstriction

AntipsychoticsDecreases dopamine activity
Males
Enhances erection
Several reported cases of priapism
Females
Enhances vaginal lubrication?
Delayed and inhibited orgasm

Anti-Parkinsonian drugsIncreases dopamine activity
Sexual drive:
Increases sex drive
Several cases of hypersexuality in men (<1%)
One reported case of hypersexuality in a woman (levodopa/carbidopa)
Sexual arousal: L-dopa increases erection in men with erectile failure

Clinical Decision making and Decision Analysis



Clinical Decision making and Decision Analysis
Presentation by: Dr. Dinesh P Mital

Hospital Based Decision Support
Medication prescribed

-Allergies -Physical examination

-Blood gases -Admit/discharge info.

-Electrocardiogram -X-ray findings

-Demographic information -Dietary information

-Cardiac data -Surgical procedures

-Biopsy results -Procedures reports

-Hematology -Respiratory notes

-Pulmonary functions -Microbiological data

-Nursing data -Pathology department data


Categories of Decision Support Technologies

1. Processes which respond to clinical data by issuing an alert.

2. Programs that respond to recorded decision to alter care by critiquing the decisions and proposing alternate care - as appropriate.

3. Applications that respond to a request by decision maker by suggesting a set of diagnosis of therapeutic maneuvers fitted to patient’s needs.

4. Retrospective quality assurance applications where clinical data are abstracted from patient’s records and decisions about the quality of care are made and fed back to care providers.
