This dose was clearly maternally toxic (increased mortality and significant body weight loss). An increase in the incidence of limb malformation (hyperextension of the forepaw) coincident with high fetal mortality was noted in a single litter at 0.6 mg/kg/day (1.2-times the HDD) in the ...
RESULTS: Local infiltration of epinephrine, L-phenylephrine, or methoxamine alone induces cutaneous anesthesia in rats in a dose-dependent way. Epinephrine is found to be 19 and 29 times more potent than those of methoxamine and L-phenylephrine, respectively. The cutaneous anesthesia induced by ...
studies in sprague-dawley male rats found that, local infiltration of l-phenylephrine could induce cutaneous anesthesia in a dose dependent manner, which could be significantly inhibited by α1-adrenergic receptor antagonists [5]. target adrenergic α1a receptor ...

characterized by reflex movement of the skin over the back produced by twitches of lateral thoracispinal muscles in response to local dorsal cutaneous noxious pinprick.Local infiltration of epinephrine, L-phenylephrine, or methoxamine alone induces cutaneous anesthesia in rats in a dose-dependent ...
A mass balance study showed that phenylephrine is extensively metabolized by the liver with only 12% of the dose excreted unchanged in the urine. Deamination by monoamino oxidase is the primary metabolic pathway resulting in the formation of the major metabolite (m-hydroxymandelic acid) which accoun...
The dose of Neo-Synephrine depends on the condition being treated. What Drugs, Substances, or Supplements Interact with Neo-Synephrine? Neo-Synephrine may interact with monoamine oxidase inhibitors (MAOIs) or beta-blockers. Talk to your doctor before taking any prescription or over-the-counter med...
DOSE/DURATION : 84 gm/kg/12W-I TOXIC EFFECTS : Sense Organs and Special Senses (Eye) - miosis (pupillary constriction) Cardiac - changes in heart weight Endocrine - changes in adrenal weight TYPE OF TEST : TDLo - Lowest published toxic dose ROUTE OF EXPOSURE : Oral SPECIES OBSERVED...
In the unadjusted analysis, there were no significant differences in phenylephrine dose administered among different genotypes at codons 16 and 27. When adjusted for covariates (maternal body mass index, baseline systolic and diastolic blood pressure, neonatal weight, and ethnicity), there was an ...
Third, this study utilized a bolus dose of phenylephrine not adjusted for patient body weight. Considering that the weight of parturients varies widely among different populations, it may be more appropriate to adjust the bolus dose of phenylephrine according to body weight. Fourth, only ...
