What's The Definition Of The Medical Condition Propranolol Hydrochloride Oral Solution?Clinical Pharmacology CLINICAL PHARMACOLOGY Mechanism Of Action The mechanism of HEMANGEOL's effects on infantile hemangiomas is not well understood.
Pharmacodynamics Propranolol is a nonselective beta-adrenergic receptor blocking agent possessing no other autonomic nervous system activity.
It specifically competes with beta-adrenergic receptor stimulating agents for available receptor sites.
When access to beta-receptor sites is blocked by propranolol, chronotropic, inotropic, and vasodilator responses to betaadrenergic stimulation are decreased proportionately.
Propranolol selectively blocks beta-adrenergic receptors, leaving alpha-adrenergic responses intact.
There are two well-characterized subtypes of beta receptors (beta1 and beta2); propranolol interacts with both subtypes equally.
Beta1-adrenergic receptors are found primarily in the heart.
Blockade of cardiac beta1-adrenergic receptors leads to a decrease in the activity of both normal and ectopic pacemaker cells and a decrease in A-V nodal conduction velocity.
Blockade of cardiac beta1-adrenergic receptors also decreases the myocardial force of contraction and may provoke cardiac decompensation in patients with minimal cardiac reserve.
Beta2-adrenergic receptors are found predominantly in smooth muscle-vascular, bronchial, gastrointestinal and genitourinary.
Blockade of these receptors results in constriction.
Propranolol's beta-blocking effects are attributable to its S(-) enantiomer.
Pharmacodynamic drug interactions Alpha blockers: Co-administration of beta-blockers with alpha blockers (prazosin) has been associated with prolongation of first dose hypotension and syncope.
Antidepressants: The hypotensive effect of MAO inhibitors and tricyclic antidepressants is exacerbated when administered with beta-blockers.
Nonsteroidal anti-inflammatory drugs: Nonsteroidal anti-inflammatory drugs (NSAIDs) may attenuate the antihypertensive effect of beta-adrenoreceptor blocking agents.
Monitor blood pressure.
Pharmacokinetics - Adults Absorption Propranolol is almost completely absorbed after oral administration.
However, it undergoes an extensive first-pass metabolism by the liver and on average; only about 25% of propranolol reaches the systemic circulation.
Peak plasma concentrations occur about 1 to 4 hours after an oral dose.
Administration of protein-rich foods increases the bioavailability of propranolol by about 50% with no change in time to peak concentration.
Propranolol is a substrate for the intestinal efflux transporter, P-glycoprotein (P-gp).
However, studies suggest that Pgp is not dose-limiting for intestinal absorption of propranolol in the usual therapeutic dose range.
Distribution Approximately 90% of circulating propranolol is bound to plasma proteins (albumin and alpha1 acid glycoprotein).
The volume of distribution of propranolol is approximately 4 L/Kg.
Propranolol crosses the blood-brain barrier and the placenta, and is distributed into breast milk.
Propranolol is extensively metabolized with most metabolites appearing in the urine.
Metabolism Propranolol is metabolized through three primary routes: aromatic hydroxylation (mainly 4hydroxylation), N-dealkylation followed by further side-chain oxidation, and direct glucuronidation.
The percentage contributions of these routes to total metabolism are 42%, 41% and 17%, respectively, but with considerable variability between individuals.
The four major final metabolites are propranolol glucuronide, naphthyloxylactic acid and glucuronic acid, and sulfate conjugates of 4-hydroxy propranolol.
In vitro studies indicated that CYP2D6 (aromatic hydroxylation), CYP1A2 (chain oxidation) and to a less extent CYP2C19 were involved in propranolol metabolism.
In healthy subjects, no difference was observed between CYP2D6 extensive metabolizers (EMs) and poor metabolizers (PMs) with respect to oral clearance or elimination half-life.
Elimination The plasma half-life of propranolol ranges from 3 to 6 hours.
Less than 1% of a dose is excreted as unchanged drug in the urine.
Infants The pharmacokinetics of propranolol and 4-OH-propranolol were evaluated in a multiple dose 12 week study conducted in 23 male and female infants 35 to 150 days of age with hemangioma.
The infants were stratified by age (35 to 90 days and 91 to 150 days).
The starting dose was 1.2 mg/kg/day which was titrated to the target dose of 3.4 mg/kg/day in 1.1 mg/kg/day increments at weekly intervals.
At steady state, following administration of 3.4 mg/kg/day twice daily, peak plasma propranolol concentrations were observed within 2 hours of oral administration.
Clearance of propranolol in infants was similar across the age range studied (2.7 (SD=0.03) L/h/kg in infants < 90 days of age and 3.3 (SD=0.35) L/h/kg in infants > 90 days of age) and to that in adults when adjusted by body weight.
The median elimination half-life of propranolol was about 3.5 hours.
Plasma propranolol concentrations approximate a dose proportional increase in the dose range of 1.2 mg/kg/day to 3.4 mg/kg/day.
Plasma concentration of 4-OH-propranolol, the main metabolite, was about 5% of total plasma exposure of propranolol.
Sex There is no known dependence of pharmacokinetics of propranolol by sex in infants.
Race There is little information on dependence of pharmacokinetics of propranolol by race in infants.
A study conducted in 12 Caucasian and 13 African-American adult male subjects taking propranolol, showed that at steady state, the clearance of R(+)-and S(-)-propranolol were about 76% and 53% higher in African-Americans than in Caucasians, respectively.
Chinese adult subjects had a greater proportion (18% to 45% higher) of unbound propranolol in plasma compared to Caucasians, which was associated with a lower plasma concentration of alpha1 acid glycoprotein.

Neurologic effects including hypoactivity and delayed air righting reflex, increased germinal centers of lymph nodes, and increased white blood cells and lymphocytes were seen at a propranolol hydrochloride dose 45.6 mg/kg/day that represents a systemic exposure of 3 times that seen in children at the MRHD.
Body weights were transiently decreased, and transient decreases in urine volume were associated with higher incidences of minimal renal cysts and dilation of kidney tubules at doses about equal to the MRHD in children.
Clinical Studies A randomized, double-blind study in 460 infants, aged 35 days to 5 months at inclusion, with proliferating infantile hemangiomas (IH) requiring systemic therapy (excluding life-threatening IH, function-threatening IH, and ulcerated IH with pain and lack of response to simple wound care measures) compared four regimens of HEMANGEOL (1.2 or 3.4 mg/kg/day in twice daily divided doses for 3 or 6 months; N=99-103 per group) to placebo (N=55).
Clinical efficacy was evaluated by counting complete or nearly complete resolution of the target hemangioma, which was evaluated by blinded centralized independent assessments of photographs at Week 24 compared to baseline.
Demographic patient characteristics and hemangioma characteristics were similar among the five regimens.
For the whole population, 29% were male, 37% were in the lower age group (35-90 days), and 72% were Caucasian.
Overall, 70% had a target hemangioma on the head, most commonly cheek (13%) and forehead (11%).
The main reason for treatment discontinuation was the treatment inefficacy, which happened in 58% of patients randomized to placebo, 25-30% of patients randomized to HEMANGEOL for 3 months (mainly after the switch to placebo), and 7-9% of patients randomized to HEMANGEOL for 6 months.
Overall, 2 out of 55 patients (4%) in the placebo arm and 61 out of 101 patients (60%) on HEMANGEOL 3.4 mg/kg/day for 6 months had complete or nearly complete resolution of their hemangioma at week 24 (p < 0.0001).
There were no significant differences in response by age (35-90 days / 91-150 days), sex, or hemangioma site.
There were too few non-Caucasians to assess differences in effects by race.
Of patients on HEMANGEOL 3.4 mg/kg/day for 6 months who were considered successes, 10% required retreatment for recurrence of hemangiomas.
A second uncontrolled study in 23 patients with proliferating IH included function-threatening IH, IH in certain anatomic locations that often leave permanent scars or deformity, large facial IH, smaller IH in exposed areas, severe ulcerated IH, pedunculated IH.
Target lesions resolved in 36% of patients by 3 months.

Medication Guide PATIENT INFORMATION HEMANGEOL™ (he-man je-ohl) (propranolol hydrochloride) Oral Solution What is the most important information I should know about HEMANGEOL? HEMANGEOL can cause serious side effects, including: Low blood sugar (hypoglycemia), especially if your child is not taking feedings, or is vomiting.
HEMANGEOL may make it more difficult to recognize the signs and symptoms of low blood sugar in your child.
To help reduce the risk of low blood sugar with HEMANGEOL: Give HEMANGEOL during or shortly after feeding your child.
Feed your child regularly during treatment.
Tell your doctor if your child has a poor appetite.
If your child is not taking feedings, for example, due to an illness or vomiting, do not give HEMANGEOL until your child is taking feedings normally again.
If your child has any of the signs or symptoms of low blood sugar listed below during treatment with HEMANGEOL, stop giving your child HEMANGEOL and call your doctor or go to the nearest emergency room right away.
Signs or symptoms of low blood sugar include: pale, blue or purple skin color, sweating, irritability, crying for no apparent reason, irregular or fast heartbeat, poor feeding, low body temperature, unusual sleepiness, seizures, breathing stops for short periods of time, and loss of consciousness.
What is HEMANGEOL? HEMANGEOL is a prescription medicine used to treat proliferating infantile hemangioma that requires treatment with a medicine that spreads throughout the body.
Who should not take HEMANGEOL? Do not give HEMANGEOL to your child if your child: was born prematurely and has not reached the corrected age of 5 weeks weighs less than 4 ½ pounds is allergic to propranolol or any of the other ingredients in HEMANGEOL.
See the end of this Medication Guide for a list of ingredients in HEMANGEOL.
has asthma or a history of breathing problems has a heart problem, slow heart rate (less than 80 heart beats per minute), very low blood pressure is at risk for low blood sugar, for example is vomiting or unable to take feedings has high blood pressure caused by a tumor on the adrenal gland, called “pheochromocytoma” What should I tell my doctor before giving my child HEMANGEOL? Before you start giving HEMANGEOL to your child, tell your doctor about all of your child's medical conditions.
Tell your doctor about all of the medicines that your child takes, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
HEMANGEOL and some medicines may interact with each other and cause serious side effects.
Especially tell your doctor if your child takes a steroid medicine.
Taking a steroid medicine during treatment with HEMANGEOL may increase your child's risk of low blood sugar.
If you are breastfeeding your child, it is important to tell your doctor about all the medicines you take.
Certain medicines may pass to your child through your breast-milk and interact with HEMANGEOL.
Your doctor should tell you if you should stop breastfeeding.
How should I give HEMANGEOL to my child? Follow the detailed Instructions for Use that come with HEMANGEOL for information about the correct way to prepare and give a dose of HEMANGEOL.
Give HEMANGEOL to your child exactly as your doctor tells you.
Your doctor may change the dose until it is right for your child, and as your child's weight changes.
Always give HEMANGEOL with a feeding or right away after a feeding.
HEMANGEOL is given 2 times each day, at least 9 hours apart.
If your child spits up a dose or if you are not sure your child got all of the medicine, do not give another dose.
Wait until the next scheduled dose.
What are the possible side effects of HEMANGEOL? See “What is the most important information I should know about HEMANGEOL?” HEMANGEOL can cause serious side effects, including: New or worsening slow heart rate (bradycardia) or low blood pressure (hypotension).
Call your doctor if your child has any of these symptoms: pale skin color, slow or uneven heartbeats, arms or legs feel cold, blue or purple skin color, or fainting.
Breathing problems or wheezing.
HEMANGEOL can cause spasms of your child's airway.
Call your doctor or go to the nearest hospital emergency room if your child has breathing problems or wheezing during treatment with HEMANGEOL.
Stroke.
HEMANGEOL may increase the risk of stroke in certain children who have severe problems with the blood vessels in their brain, particularly if your child has a large hemangioma that affects the face or head.
The most common side effects include: sleep problems, worsening respiratory tract infections, diarrhea, and vomiting.
These are not all the possible side effects of HEMANGEOL.

Overdosage & Contraindications Side Effects & Drug Interactions SIDE EFFECTS The following serious adverse reactions are discussed in greater detail in other sections of the labeling: Hypoglycemia and related events, like hypoglycemic seizure [see WARNINGS AND PRECAUTIONS].
Bronchospasm [see WARNINGS AND PRECAUTIONS].
Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in clinical practice.
Clinical Trials Experience with HEMANGEOL in Infants with proliferating infantile hemangioma In clinical trials for proliferating infantile hemangioma, the most frequently reported adverse reactions ( > 10%) in infants treated with HEMANGEOL were sleep disorders, aggravated respiratory tract infections such as bronchitis and bronchiolitis associated with cough and fever, diarrhea, and vomiting.
Adverse reactions led to treatment discontinuation in fewer than 2% of treated patients.
Overall, 479 patients in the pooled safety population were exposed to study drug in the clinical study program (456 in placebo-controlled trials).
A total of 424 patients were treated with HEMANGEOL at doses 1.2 mg/kg/day or 3.4 mg/kg/day for 3 or 6 months.
Of these, 63% of patients were aged 91-150 days and 37% were aged 35-90 days at randomization.
The following table lists according to the dosage the most common adverse reactions (treatment-emergent adverse events with an incidence at least 3% greater on one of the two doses than on placebo).
Table 2: Treatment-emergent adverse events occurring at least 3% more often on HEMANGEOL than on placebo.
Reaction Placebo N=236 HEMANGEOL 1.2 mg/kg/day N=200 HEMANGEOL 3.4 mg/kg/day N=224 Sleep disorder 5.90% 17.50% 16.10% Bronchitis 4.7 8 13.4 Peripheral coldness 0.4 8 6.7 Agitation 2.1 8.5 4.5 Diarrhea 1.3 4.5 6.3 Somnolence 0.4 5 0.9 Nightmare 1.7 2 6.3 Irritability 1.3 5.5 1.3 Decreased appetite 0.4 2.5 3.6 Abdominal pain 0.4 3.5 0.4 The following adverse events have been observed during clinical studies, with an incidence of less than 1%: Cardiac disorders: Second degree atrioventricular heart block, in a patient with underlying conduction disorder, required definitive treatment discontinuation [see WARNINGS AND PRECAUTIONS].
Skin and subcutaneous tissue disorders: Urticaria, alopecia Investigations: Decreased blood glucose, decreased heart rate Compassionate Use Program More than 600 infants received HEMANGEOL in a compassionate use program (CUP).
Mean age at treatment initiation was 3.6 months.
Mean dose of HEMANGEOL was 2.2 mg/kg/day and mean treatment duration was 7.1 months.
The adverse reactions reported in the CUP were similar to the ADRs observed during clinical trials but some were more severe.
Postmarketing Experience The following adverse reactions have been identified during post-approval use of propranolol.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
These adverse reactions are as follows: Blood and lymphatic system disorders: Agranulocytosis Psychiatric disorders: Hallucination Skin and subcutaneous tissues disorders: Purpura DRUG INTERACTIONS In the absence of specific studies in children, the drug interactions with propranolol are those known in adults.
Consider both the infant's medications and those of a nursing mother.
Pharmacokinetic drug interactions Impact of co-administered drugs on propranolol: CYP2D6, CYP1A2 or CYP2C19 inhibitors increase propranolol plasma concentration.
CYP1A2 inducers (phenytoin, phenobarbital) or CYP2C19 inducers (rifampin) decrease propranolol plasma concentration when co-administered.
Pharmacodynamic drug interactions Corticosteroids: Patients on corticosteroids may be at increased risk of hypoglycemia because of loss of the counter-regulatory cortisol response; monitor patients for signs of hypoglycemia.
Warnings & Precautions WARNINGS Included as part of the PRECAUTIONS section.
PRECAUTIONS Hypoglycemia HEMANGEOL prevents the response of endogenous catecholamines to correct hypoglycemia and masks the adrenergic warning signs of hypoglycemia, particularly tachycardia, palpitations and sweating.
HEMANGEOL can cause hypoglycemia in children, especially when they are not feeding regularly or are vomiting; withhold the dose under these conditions.
Hypoglycemia may present in the form of seizures, lethargy, or coma.
If a child has clinical signs of hypoglycemia, discontinue HEMANGEOL and call their health care provider immediately or take the child to the emergency room.
Concomitant treatment with corticosteroids may increase the risk of hypoglycemia [see DRUG INTERACTIONS].
Bradycardia And Hypotension HEMANGEOL may cause or worsen bradycardia or hypotension.
In the studies of HEMANGEOL for infantile hemangioma the mean decrease in heart rate was about 7 bpm with little effect on blood pressure.
Monitor heart rate and blood pressure after treatment initiation or increase in dose.
Discontinue treatment if severe ( < 80 beats per minute) or symptomatic bradycardia or hypotension (systolic blood pressure < 50 mmHg) occurs.
Bronchospasm HEMANGEOL can cause bronchospasm; do not use in patients with asthma or a history of bronchospasm.
Interrupt treatment in the event of a lower respiratory tract infection associated with dyspnea and wheezing.
Cardiac Failure Sympathetic stimulation supports circulatory function in patients with congestive heart failure, beta blockade may precipitate more severe failure.
Increased Risk Of Stroke In PHACE Syndrome By dropping blood pressure, HEMANGEOL may increase the risk of stroke in PHACE syndrome patients with severe cerebrovascular anomalies.
Investigate infants with large facial infantile hemangioma for potential arteriopathy associated with PHACE syndrome prior to HEMANGEOL therapy.
Hypersensitivity Beta blockers will interfere with epinephrine used to treat serious anaphylaxis.
Patient Counseling Information See FDA-approved patient labeling (Medication Guide and Instructions for Use).
Patient advice Advise parents or caregivers to read the FDA-approved patient labeling (Medication Guide and Instructions for Use).
Instructions for using oral dosing syringe Instruct parents or caregivers on use of the oral dosing syringe.
Risk of hypoglycemia Inform parents or caregivers that there is a risk of hypoglycemia when HEMANGEOL is given to infants who are not feeding regularly or who are vomiting.
Instruct them to skip dosing under such conditions.
Instruct parents or caregivers how to recognize the signs of hypoglycemia.
Tell them to discontinue HEMANGEOL and call their health care provider immediately or take the child to the emergency room in case of suspected hypoglycemia.
Cardiovascular risks Advise parents or caregivers that there is a potential risk for bradycardia, aggravation of pre-existing conduction disorders, and hypotension associated with the use of HEMANGEOL.
Instruct them to contact their healthcare provider in case of fatigue, pallor, slow or uneven heart beats, peripheral coldness or fainting.
Respiratory risks Inform parents or caregivers that HEMANGEOL carries risk of bronchospasm or exacerbation of lower respiratory tract infections.
Instruct them to contact their healthcare provider or go to the nearest hospital emergency room if their child has breathing problems or wheezing during treatment with HEMANGEOL.
Other risks Inform parents or caregivers that changes in sleep patterns may occur during HEMANGEOL therapy.
Ask parents or caregivers to tell you all the medications they are administering to their child including prescription and over the counter medicines, vitamins, and herbal supplements.
Ask breastfeeding mothers to tell you all the medications they are currently taking, as these may pass into the milk.
Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility In studies of mice and rats fed propranolol hydrochloride for up to 18 months at doses of up to 150 mg/kg/day, there was no evidence of drug-related tumorigenesis.
On a body surface area basis, this dose in the mouse and rat is about 3 and 7 times, respectively, the MRHD of 3.4 mg/kg/day propranolol hydrochloride in children.
Based on differing results from bacterial reverse mutation (Ames) tests performed by different laboratories, there is equivocal evidence for mutagenicity in one strain (S.
typhimurium strain TA 1538).
In a study in which both male and female rats were exposed to propranolol hydrochloride via diet at concentrations of up to 0.05% (about 50 mg/kg or less than the MRHD of 640 mg propranolol hydrochloride in adults) started from 60 days prior to mating and throughout pregnancy and lactation for two generations, there were no effects on fertility.
The potential effects of propranolol hydrochloride on fertility of juvenile rats were evaluated following daily oral administration from post-natal Day 4 (PND 4) to PND 21 at dose-levels of 0, 11.4, 22.8 or 45.6 mg/kg/day.
No propranolol related effects on reproductive parameters or reproductive development were observed up to the highest dose level of 45.6 mg/kg/day, a dose that represents a systemic exposure of 3 times that seen in children at the MRHD.
Use In Specific Populations Pregnancy HEMANGEOL is not intended to be prescribed to pregnant women [see INDICATIONS AND USAGE].
Pregnancy Category C In a series of reproductive and developmental toxicology studies, propranolol hydrochloride was given to rats by gavage or in the diet throughout pregnancy and lactation.
At a dose of 150 mg/kg/day [which is about 2 times the maximum recommended human oral daily dose (MRHD) of 640 mg propranolol hydrochloride in adults on a body surface area basis], treatment was associated with embryotoxicity (reduced litter size and increased resorption rates) as well as neonatal toxicity (deaths).
Propranolol hydrochloride also was administered in the feed to rabbits throughout pregnancy and lactation at doses up to 150 mg/kg/day (about 5 times the maximum recommended human oral daily dose in adults).
No evidence of embryo or neonatal toxicity was noted.
There are no adequate and well-controlled studies in pregnant women.
Intrauterine growth retardation, small placentas, and congenital abnormalities have been reported in neonates whose mothers received propranolol during pregnancy.
Neonates whose mothers received propranolol at parturition have exhibited bradycardia, hypoglycemia, and respiratory depression.
Adequate facilities for monitoring such infants at birth should be available.
Nursing Mothers HEMANGEOL is not intended to be prescribed to breastfeeding women [see INDICATIONS AND USAGE].
Propranolol is excreted in human milk.
Pediatric Use Of 460 infants with proliferating infantile hemangioma requiring systemic therapy who were treated with HEMANGEOL starting at 5 weeks to 5 months of age, 60% had complete or nearly complete resolution of their hemangioma at week 24 [see Clinical Studies].
Safety and effectiveness for infantile hemangioma have not been established in pediatric patients greater than 1 year of age.
Hepatic Impairment There is no experience in infants with hepatic impairment.
Renal Impairment There is no experience in infants with renal impairment.
