ANIMAL PHARMACOLOGY & OR TOXICOLOGY SECTION.


ANIMAL PHARMACOLOGY OR TOXICOLOGY. Oraldiazoxide in themouse, rat, rabbit,dog,pig, and monkey produces rapid and transientrise in blood glucoselevels.Indogs,increasedbloodglucose is accompanied by increasedfreefattyacids,lactate, and pyruvate in theserum.Inmice, markeddecrease in liverglycogen and an increase in the bloodureanitrogenlevel occur.In acute toxicitystudies theLD50for oral diazoxidesuspension is >5000mg/kg in the rat,>522mg/kg in the neonatalrat,between 1900 and 2572 mg/kg in the mouse,and219mg/kg in the guineapig.Although the oralLD50was not determined in thedog, dosage of up to 500 mg/kgwas welltolerated.Insubacuteoraltoxicity studies, diazoxide at 400 mg/kg in the rat producedgrowthretardation,edema,increases in liverand kidney weights, and adrenalhypertrophy. Daily dosages up to 1080 mg/kgfor three months producedhyperglycemia, an increase in liverweightand an increase in mortality.Indogsgiven oral diazoxide at approximately 40 mg/kg/dayfor one month, no biologicallysignificantgross or microscopicabnormalities wereobserved.Cataracts,attributed to markedlydisturbedcarbohydratemetabolism,have been observed in few dogsgivenrepeateddailydoses of oral or intravenous diazoxide. The lenticularchanges resembledthosewhichoccurexperimentally in animalswithincreasedbloodglucoselevels.Inchronictoxicitystudies, rats given dailydose of 200 mg/kgdiazoxidefor 52 weeks had decrease in weightgain and an increase in heart, liver,adrenalandthyroidweights.Mortalityindrug-treated and controlgroups was not different.Dogs treated withdiazoxide at dosages of 50, l00, and 200 mg/kg/dayfor 82 weeks had higher blood glucoselevels than controls.Mild bone marrow stimulation and increasedpancreasweights wereevident in thedrug-treateddogs;severaldevelopedinguinalhernias, one had testicularseminoma,andanotherhad mass nearthepenis.Twofemales hadinguinalmammaryswellings. The etiologyofthesechanges was not established.Therewas no difference in mortalitybetweendrug-treated and controlgroups.In secondchronicoraltoxicitystudy,dogsgiven milled diazoxide at 50, l00, and 200mg/kg/day had anorexia and severweightloss,causing death in few.Hematologic,biochemical, and histologicexamination did not indicate any cause of death otherthaninanition.Afteroneyear of treatment,there is no evidence of herniation or tissueswelling in any of the dogs.Whendiazoxidewas administered at highdosages concomitantlywitheitherchlorothiazide to rats or trichlormethiazide to dogs,increasedtoxicitywas observed.Inrats, the combinationwasnephrotoxic;epithelialhyperplasiawas observed in the collectingtubules.Indogs, diabetic syndromewas produced whichresulted in ketosis anddeath.Neither of thedrugsgiven alone produced theseeffects.Although the data are inconclusive,reproduction and teratologystudies in severalspecies of animalsindicatethatdiazoxide,whenadministered during thecriticalperiod of embryoformation, may interferewithnormalfetaldevelopment,possiblythroughalteredglucosemetabolism.Parturitionwas occasionally prolonged in animals treatedatterm.Intravenous administration of diazoxide to pregnantsheep,goats, and swineproduced in the fetus an appreciableincrease in blood glucoselevel and degeneration of the betacells of the Islets of Langerhans. The reversibility of these effects was not studied.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


CARCINOGENESIS MUTAGENESIS IMPAIRMENT OF FERTILITY. Nolong-termanimaldosing study has been done to evaluatethecarcinogenicpotential of diazoxide.Nolaboratory study of mutagenicpotential or animalstudyofeffects on fertility has been done.

CLINICAL PHARMACOLOGY SECTION.


CLINICAL PHARMACOLOGY. Diazoxideadministeredorally produces promptdose-relatedincrease in bloodglucoselevel,dueprimarily to an inhibition of insulinreleasefromthepancreas,andalso to an extrapancreaticeffect. The hyperglycemiceffectbegins within an hour and generallylasts no more thaneight hours in the presence of normalrenalfunction.Diazoxidedecreases theexcretion of sodium and water,resulting in fluidretentionwhichmay be clinicallysignificant.The hypotensiveeffect of diazoxide on blood pressure is usually not marked withtheoralpreparation.This contrastswiththeintravenous preparation of diazoxide(seeADVERSEREACTIONS).Otherpharmacologicactions of diazoxideincludeincreasedpulserate;increasedserumuricacidlevels due to decreasedexcretion;increasedserumlevels of freefattyacidsdecreasedchlorideexcretion;decreasedpara-aminohippuricacid;(PAH)clearancewith no appreciableeffect on glomerularfiltrationrate.The concomitantadministration of benzothiazidediuretic may intensify the hyperglycemic and hyperuricemiceffects of diazoxide.Inthepresence of hypokalemia,hyperglycemiceffects are alsopotentiated.Diazoxide-inducedhyperglycemia is reversed by the administration of insulin or tolbutamide. The inhibition of insulinrelease by diazoxide is antagonizedbyalphaadrenergicblockingagents.Diazoxideis extensively bound (morethan 90%) to serumproteins, and is excreted in thekidneys. The plasmahalf-lifefollowingI.V.administrationis 28 +- 8.3 hours.Limited data onoraladministrationrevealed half-life of 24 and 36 hours in twoadults.Infour children agedfour months to sixyears, the plasmahalf-lifevariedfrom 9.5 to 24 hours on long-termoraladministration. The half-life may be prolongedfollowingoverdosage, and in patients withimpaired renal function.

CONTRAINDICATIONS SECTION.


CONTRAINDICATIONS. The use of Diazoxide Oral Suspension, USP for functional hypoglycemia is contraindicated. The drug should not be used in patients hypersensitive to diazoxide or to other thiazides unless the potential benefits outweigh the possible risks.

It is whitepowderpracticallyinsoluble to sparinglysoluble in water.. structure.

DOSAGE & ADMINISTRATION SECTION.


DOSAGE ADMINISTRATION. Patients should be under close clinical observation when treatment with Diazoxide oral suspension, USP isinitiated. The clinical response and blood glucose level should be carefully monitored until the patients condition has stabilized satisfactory; in most instances, this may be accomplished in several days. If administration of Diazoxide oral suspension, USP is not effective after two or three weeks, the drug should be discontinued.The dosage of Diazoxide oral suspension, USP must be individualized based on the severity of the hypoglycemicconditionand the bloodglucoselevel and clinicalresponse of thepatient.Thedosageshould be adjusteduntilthedesiredclinical and laboratoryeffects are producedwiththeleastamount of the drug.Specialcareshould be taken to assureaccuracyofdosage in infants and young children.Adults and children:The usualdailydosage is to mg/kg,divided into two or threeequaldoses every or 12 hours.Incertaininstances,patientswithrefractoryhypoglycemia may require higherdosages.Ordinarily, an appropriatestartingdosage is mg/kg/day, divided intothreeequaldoses every hours. Thus an average adult wouldreceive startingdosage of approximately 200 mg daily.Infants and newborns: The usualdailydosage is to 15 mg/kgdivided into two or threeequaldoses every to 12 hours.Anappropriatestartingdosage is 10 mg/kg/day, divided into threeequaldosesevery hours.

DRUG & OR LABORATORY TEST INTERACTIONS SECTION.


DRUG OR LABORATORY TEST INTERACTIONS. The hyperglycemic and hyperuricemic effects of diazoxide preclude proper assessment of these metabolic states.Increased renin secretion,IgG concentrations and decreased cortisolsecretions have alsobeennoted.Diazoxide inhibits glucagon-stimulated insulin release and causes false-negative insulinresponse to glucagon.

DRUG INTERACTIONS SECTION.


DRUG INTERACTIONS. Sincediazoxideis highly bound to serumproteins,it may displaceothersubstances whicharealso bound to protein,such as bilirubin or coumarin and its derivatives,resulting in higher blood levels of thesesubstances.Concomitantadministration of oraldiazoxideanddiphenylhydantoinmayresult in loss of seizurecontrol.Thesepotentialinteractions must be consideredwhenadministeringDiazoxideCapsules or Suspension.The concomitantadministration of thiazides or othercommonlyuseddiuretics may potentiate the hyperglycemic and hyperuricemiceffects of diazoxide.

GENERAL PRECAUTIONS SECTION.


GENERAL PRECAUTIONS. Treatment with Diazoxide Oral Suspension, USP should be initiated under close clinical supervision, with careful monitoring of blood glucose and clinical response until the patients condition has stabilized. This usually requires several days. If not effective in two to three weeks, the drug should be discontinued.Prolongedtreatmentrequires regularmonitoring of the urineforsugar and ketones,especially under stressconditions,withpromptreporting of any abnormalities to the physician.Additionally, blood sugarlevels should be monitoredperiodicallyby the physician to determinetheneedfordoseadjustment.The effects of diazoxideon the hematopoieticsystem and the level of serumuricacidshould be kept in mind;thelattershould be consideredparticularly in patients withhyperuricemia or historyofgout.Insomepatients,higherbloodlevels havebeenobservedwith the oralsuspensionthanwith the capsuleformulation of diazoxide.Dosageshould be adjusted as necessary in individualpatients if changedfrom one formulation to the other.Sincetheplasmahalf-lifeof diazoxide is prolonged in patients withimpairedrenalfunction, reduceddosageshouldbe considered.Serumelectrolytelevels shouldalso be evaluatedforsuch patients.The antihypertensive effect of other drugs may be enhanced by Diazoxide Oral Suspension, USP and this should be kept in mind when administering it concomitantly with antihypertensive agents. Because of the protein binding, administration of Diazoxide Oral Suspension, USP with coumarin or its derivatives may require reduction in the dosage of the anticoagulant, although there has been no reportedevidence of excessiveanticoagulanteffect.In addition, diazoxidemay possibly displacebilirubinfromalbumin;this should be kept in mindparticularlywhentreatingnewborns withincreasedbilirubinemia.Pulmonaryhypertension has been reportedinneonates and younginfants treatedwithdiazoxide.(seeWARNINGS).

LABOR DELIVERY. Since intravenous administration of the drug during labormay cause cessation of uterine contractions, and administration of oxytocic agents may be required to reinstate labor, caution is advised in administering Diazoxide oral suspension, USP at that time.

LABORATORY TESTS SECTION.


LABORATORY TESTS. The followingprocedures may be especiallyimportant in patientmonitoring (not necessarilyinclusive); blood glucosedeterminations (recommendedatperiodicintervals inpatients takingdiazoxideorallyfortreatment of hypoglycemia,untilstabilized);bloodureanitrogen(BUN)determinations and creatinineclearancedeterminations;hematocritdeterminations;platelet count determinations;total and differentialleukocytecounts;serumaspartateaminotransferase(AST)leveldeterminations;serumuricacidleveldeterminations; and urinetestingforglucose and ketones (in patients beingtreatedwithdiazoxideforhypoglycemia,semiquantitativeestimation of sugar and ketones in serumperformed by the patientandreported to the physicianprovides frequentandrelativelyinexpensivemonitoring of the condition).

NURSING MOTHERS SECTION.


NURSING MOTHERS. Information is not available concerning the passage of diazoxide in breast milk.Because many drugs are excreted in human milk and because of the potentialforadverse reactions from diazoxide in nursing infants, decision should be made whethertodiscontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

OVERDOSAGE SECTION.


OVERDOSAGE. An overdosage of Diazoxide oral suspension, USP causes marked hyperglycemia which may be associated with ketoacidosis. It will respond to prompt insulin administration and restoration of fluid and electrolyte balance. Because of the drugs long half-life (approximately 30 hours), the symptoms of overdosage require prolonged surveillance for periods up to seven days until the blood sugar level stabilizes within the normalrange.Oneinvestigatorreportedsuccessfulloweringofdiazoxidebloodlevels by peritonealdialysis in one patient and by hemodialysis in another.

WARNINGS SECTION.


WARNINGS. The antidiureticproperty of diazoxidemay lead to significantfluidretention,which in patients withcompromisedcardiacreserve, may precipitatecongestive heart failure.Thefluidretentionwillrespond to conventionaltherapywithdiuretics.Itshould be notedthatconcomitantlyadministeredthiazides maypotentiatethehyperglycemic and hyperuricemicactions of diazoxide(SeeDRUG INTERACTIONS and ANIMALPHARMACOLOGYAND/ORTOXICOLOGY).Ketoacidosis and nonketotic hyperosmolar coma have been reported in patients treated with recommended doses of Diazoxide Oral Suspension, USP usually during intercurrent illness. Prompt recognition and treatment are essential(SeeOVERDOSAGE), and prolongedsurveillancefollowing the acuteepisode is necessarybecause of the long drug half-life of approximately 30 hours. The occurrence of theseserious events may be reduced bycarefuleducation of patients regarding the need formonitoring the urineforsugar and ketones and for prompt reporting of abnormal findings and unusualsymptoms to the physician.Transientcataracts occurred in associationwith hyperosmolarmain an infant, and subsidedoncorrection of the hyper-osmolarity.Cataracts have been observed in severalanimals receiving daily doses of intravenous or oraldiazoxide.The development of abnormal facial features in four children treated chronically (>4 years) with Diazoxide Oral Suspension, USP for hypoglycemia hyperinsulinism in the same clinic has been reported. Pulmonary Hypertension in Neonates and InfantsTherehavebeenpostmarketingreports of pulmonaryhypertensionoccurring in infants and neonatestreatedwithdiazoxide.Thecases werereversibleupondiscontinuation of the drug.Monitorpatients,especiallythosewithriskfactors for pulmonary hypertension,forrespiratory distress and discontinuediazoxide if pulmonaryhypertension is suspected.
