CONTRACTIONS IN RESPONSE TO PROSTAGLANDIN F2ALPHA IN HUMAN ISOLATED BRONCHIAL MUSCLE ARE INHIBITED BY FENAMATES, PHENYLBUTAZONE, &, LESS POTENTLY, ASPIRIN.

INTRADERMAL INJECTION OF.../PROSTAGLANDIN F2ALPHA/ IN MAN CAUSES "WHEAL & FLARE."

SIDE EFFECTS ATTENDING USE OF PROSTAGLANDINS IN SECOND & THIRD TRIMESTER & @ TERM ARE CAUSED BY THEIR STIMULATORY ACTION ON SMOOTH MUSCLE OF ALIMENTARY TRACT, THAT IS, NAUSEA, VOMITING, & DIARRHEA. /PROSTAGLANDINS/

CERVICAL OR LOWER UTERINE LACERATION OR RUPTURE, WITH RETENTION OF PLACENTA & HEMORRHAGE, IS PERHAPS MOST IMPORTANT DANGER WITH USE...FOR 2ND-TRIMESTER ABORTION. ... FEVER, HYPOTENSION & SYNCOPE, HYPERTENSION, HEADACHE, & PAIN & ERYTHEMA @ SITE OF INJECTION OCCUR LESS FREQUENTLY. /DINOPROST TROMETHAMINE/

IN PREGNANT RATS TREATED SC @ 50 UG, DAYS 9-11 OR 12-15 OF GESTATION, PLACENTA SHOWED EXTENSIVE AREAS OF DEGENERATION THAT ARE FOUND IN PLACENTAL INSUFFICIENCY. ALSO FETAL ADRENAL CORTEX SHOWED MORPHOLOGICAL CHANGES INDICATIVE OF INTRAUTERINE DISTRESS.

SINCE DINOPROST IS METABOLIZED RAPIDLY, DISCONTINUATION OF DRUG & SUPPORTIVE THERAPY ARE ADEQUATE TREATMENT...BLOOD TRANSFUSIONS MAY BE REQUIRED /FOR HEMORRHAGE DUE TO RETENTION OF PLACENTA/

RESPONSES TO PROSTAGLANDIN F2ALPHA SHOW SPECIES VARIATION, BUT VASODILATATION HAS BEEN OBSERVED FOLLOWING INJECTION INTO HUMAN BRACHIAL ARTERY OF PGF2ALPHA... SUPERFICIAL VEINS OF HAND ARE CONTRACTED BY PFG2ALPHA...

PROMPT SUBSIDENCE OF PROGESTERONE OUTPUT & REGRESSION OF CORPUS LUTEUM FOLLOWS PARENTERAL INJECTION OF PROSTAGLANDIN F2ALPHA... THIS EFFECT INTERRUPTS EARLY PREGNANCY, WHICH IS DEPENDENT ON LUTEAL RATHER THAN PLACENTAL PROGESTERONE.

Non-steroidal chemical compounds with abortifacient activity.

Drugs that stimulate contraction of the myometrium. They are used to induce LABOR, OBSTETRIC at term, to prevent or control postpartum or postabortion hemorrhage, and to assess fetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (ABORTIFACIENTS). Oxytocics used clinically include the neurohypophyseal hormone OXYTOCIN and certain prostaglandins and ergot alkaloids. (From AMA Drug Evaluations, 1994, p1157)

AMONG COMPD OCCURRING IN SEMEN THAT ARE OF CURRENT RESEARCH INTEREST ARE PROSTAGLANDINS (25 MG/ML). /PROSTAGLANDINS/

APART FROM GENERALLY SLOW & SPECIES-DEPENDENT ISOMERIZATION, PGS E & F ARE RATHER STABLE IN BLOOD, BUT THEY ARE RAPIDLY DEGRADED & INACTIVATED BY TISSUE-BOUND ENZYMES; SOME 80-90% OR MORE IS DESTROYED DURING SINGLE PASSAGE THROUGH LIVER OR LUNGS. /PROSTAGLANDINS/

DEG OF BINDING OF PROSTAGLANDINS TO PLASMA PROTEINS APPEARS TO HAVE LITTLE INFLUENCE ON THEIR RATES OF METABOLISM & ELIMINATION. ... CLEARANCE RATES OF (3)H DID NOT CHANGE WHETHER PROSTAGLANDINS WERE ADMIN IN FREE FORM OR BOUND TO RAT PLASMA ALBUMIN. /PROSTAGLANDINS/
