Uses of Levocetirizine (Lenex) in details

Levocetirizine (Lenex) is used to treat symptoms of allergic conditions such as allergic fever (hay fever), year-round allergies like dust or pet allergies and chronic nettle rash.

Levocetirizine (Lenex) description

Levocetirizine (Lenex) is a third-generation non-sedative antihistamine indicated for the relief of symptoms associated with seasonal and perennial allergic rhinitis and uncomplicated skin manifestations of chronic idiopathic urticaria. It was developed from the second-generation antihistamine cetirizine. Levocetirizine (Lenex) is the R-enantiomer of the cetirizine racemate. Levocetirizine (Lenex) is an inverse agonist that decreases activity at histamine H1 receptors. This in turn prevents the release of other allergy chemicals and increased blood supply to the area, and provides relief from the typical symptoms of hay fever. It does not prevent the actual release of histamine from mast cells. Levocetirizine (Lenex) was approved by the United States Food and Drug Administration on May 25, 2007 and is marketed under the brand Levocetirizine (Lenex)® by sanofi-aventis U.S. LLC.

What other drugs will affect Levocetirizine (Lenex)?

Drug interaction studies have been performed with racemic cetirizine.

Antipyrine, Azithromycin, Cimetidine, Erythromycin, Ketoconazole, Theophylline and Pseudoephedrine: Pharmacokinetic interaction studies performed with racemic cetirizine demonstrated that cetirizine did not interact with antipyrine, pseudoephedrine, erythromycin, azithromycin, ketoconazole and cimetidine. There was a small decrease (approximately 16%) in the clearance of cetirizine caused by theophylline 400 mg dose. It is possible that higher theophylline doses could have a greater effect.

Interactions with Other Medicaments: No interaction studies have been performed with Levocetirizine (Lenex) (including no studies with CYP3A4 inducers); studies with the racemate compound, cetirizine demonstrated that there were no clinically relevant adverse interactions (with pseudoephedrine, cimetidine, ketoconazole, erythromycin, azithromycin, glipizide and diazepam). A small decrease in the clearance of cetirizine (16%) was observed in a multiple-dose study with theophylline (400 mg once a day); while the disposition of theophylline was not altered by concomitant cetirizine administration.

The extent of absorption of Levocetirizine (Lenex) is not reduced with food, although the rate of absorption is decreased.

In sensitive patients the simultaneous administration of cetirizine or Levocetirizine (Lenex) and alcohol or other CNS depressants, may have effects on the central nervous system, although it has been shown that the racemate cetirizine does not potentiate the effect of alcohol.

Clinical Trials Experience

The safety data described below reflect exposure to Levocetirizine (Lenex) in 2708 patients with seasonal or perennial allergic rhinitis or chronic idiopathic urticaria in 14 controlled clinical trials of 1 week to 6 months duration.

The short-term (exposure up to 6 weeks) safety data for adults and adolescents are based upon eight clinical trials in which 1896 patients (825 males and 1071 females aged 12 years and older) were treated with Levocetirizine (Lenex) 2.5, 5, or 10 mg once daily in the evening.

The short-term safety data from pediatric patients are based upon two clinical trials in which 243 children with seasonal or perennial allergic rhinitis (162 males and 81 females 6 to 12 years of age) were treated with Levocetirizine (Lenex) 5 mg once daily for 4 to 6 weeks, one clinical trial in which 114 children (65 males and 49 females 1 to 5 years of age) with allergic rhinitis or chronic idiopathic urticaria were treated with Levocetirizine (Lenex) 1.25 mg twice daily for 2 weeks, and one clinical trial in which 45 children (28 males and 17 females 6 to 11 months of age) with symptoms of allergic rhinitis or chronic urticaria were treated with Levocetirizine (Lenex) 1.25 mg once daily for 2 weeks.

The long-term (exposure of 4 or 6 months) safety data in adults and adolescents are based upon two clinical trials in which 428 patients (190 males and 238 females) with allergic rhinitis were exposed to treatment with Levocetirizine (Lenex) 5 mg once daily. Long term safety data are also available from an 18-month trial in 255 Levocetirizine (Lenex)-treated subjects 12-24 months of age.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice.

Adults and Adolescents 12 years of Age and Older

In studies up to 6 weeks in duration, the mean age of the adult and adolescent patients was 32 years, 44% of the patients were men and 56% were women, and the large majority (more than 90%) was Caucasian.

In these trials 43% and 42% of the subjects in the Levocetirizine (Lenex) 2.5 mg and 5 mg groups, respectively, had at least one adverse event compared to 43% in the placebo group.

In placebo-controlled trials of 1-6 weeks in duration, the most common adverse reactions were somnolence, nasopharyngitis, fatigue, dry mouth, and pharyngitis, and most were mild to moderate in intensity. Somnolence with Levocetirizine (Lenex) showed dose ordering between tested doses of 2.5, 5 and 10 mg and was the most common adverse reaction leading to discontinuation (0.5%).

Table 1 lists adverse reactions that were reported in greater than or equal to 2% of subjects aged 12 years and older exposed to Levocetirizine (Lenex) 2.5 mg or 5 mg in eight placebo-controlled clinical trials and that were more common with Levocetirizine (Lenex) than placebo.

Pediatric Patients 6 To 11 Months Of Age

A total of 45 pediatric patients 6 to 11 months of age received Levocetirizine (Lenex) 1.25 mg once daily in a two week placebo-controlled double-blind safety trial. The mean age of the patients was 9 months, 51% were Caucasian and 31% were Black. Adverse reactions that were reported in more than 1 subject (i.e. greater than or equal to 3% of subjects) aged 6 to 11 months exposed to Levocetirizine (Lenex) 1.25 mg once daily in the placebo-controlled safety trial and that were more common with Levocetirizine (Lenex) than placebo included diarrhea and constipation which were reported in 6 (13%) and 1 (4%) and 3 (7%) and 1 (4%) children in the Levocetirizine (Lenex) and placebo-treated groups, respectively.

Long-Term Clinical Trials Experience

In two controlled clinical trials, 428 patients (190 males and 238 females) aged 12 years and older were treated with Levocetirizine (Lenex) 5 mg once daily for 4 or 6 months. The patient characteristics and the safety profile were similar to that seen in the short-term studies. Ten (2.3%) patients treated with Levocetirizine (Lenex) discontinued because of somnolence, fatigue or asthenia compared to 2 ( < 1%) in the placebo group.

There are no long term clinical trials in children below 12 years of age with allergic rhinitis or chronic idiopathic urticaria.

Laboratory Test Abnormalities

Elevations of blood bilirubin and transaminases were reported in < 1% of patients in the clinical trials. The elevations were transient and did not lead to discontinuation in any patient.

Post-Marketing Experience

In addition to the adverse reactions reported during clinical trials and listed above, adverse reactions have also been identified during post-approval use of Levocetirizine (Lenex). 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. Adverse reactions of hypersensitivity and anaphylaxis, increased appetite, angioedema, fixed drug eruption, pruritus, rash and urticaria, convulsion, paraesthesia, dizziness, tremor, dysgeusia, vertigo, movement disorders (including dystonia and oculogyric crisis), aggression and agitation, hallucinations, depression, insomnia, suicidal ideation, visual disturbances, blurred vision, palpitations, tachycardia, dyspnea, nausea, vomiting, hepatitis, dysuria, urinary retention, myalgia, arthralgia, and edema have been reported.

Besides these reactions reported under treatment with Levocetirizine (Lenex), other potentially severe adverse events have been reported from the post-marketing experience with cetirizine. Since Levocetirizine (Lenex) is the principal pharmacologically active component of cetirizine, one should take into account the fact that the following adverse events could also potentially occur under treatment with Levocetirizine (Lenex): orofacial dyskinesia, severe hypotension, cholestasis, glomerulonephritis, still birth, tic, myoclonus, and extrapyramidal symptoms.

Uses of Phenylephrine (Lenex) in details

Use: Labeled Indications

Hypotension/shock: Treatment of hypotension, vascular failure in shock. Note: Not recommended for routine use in the treatment of septic shock; use should be limited until more evidence demonstrating positive clinical outcomes becomes available (Rhodes 2017).

Guideline recommendations:

Cardiogenic shock: The 2017 American Heart Association (AHA) scientific statement for the Contemporary Management of Cardiogenic Shock recommends Phenylephrine (Lenex), if needed, be considered for initial vasoactive management of cardiogenic shock due to aortic stenosis, mitral stenosis, or dynamic left ventricular outflow tract (LVOT) obstruction (AHA [van Diepen 2017]).

Hypotension during anesthesia: As a vasoconstrictor in regional analgesia

Nasal congestion: As a decongestant [OTC]

Off Label Uses

Hypotension in patients with obstructive hypertrophic cardiomyopathy

Phenylephrine (Lenex) is a pure alpha1 agonist that will increase systemic vascular resistance without increasing heart rate or contractility. This is advantageous in patients with obstructive hypertrophic cardiomyopathy and hypotension since increases in both heart rate and contractility may cause the obstruction to worsen, leading to a decrease in cardiac output. Other vasopressors like dopamine, epinephrine, and norepinephrine may increase contractility and/or heart rate. Additional trials may be necessary to further define the role of Phenylephrine (Lenex) in this condition.

Based on the American Urological Association guidelines for the management of priapism, due to the low risk of cardiovascular side effects intracavernous injection of Phenylephrine (Lenex) is recommended for ischemic priapism that persists following aspiration/irrigation.

Phenylephrine (Lenex) description

Phenylephrine (Lenex) is a sympathomimetic amine that acts predominantly on α-adrenergic receptors. It is mainly used to treat nasal congestion, but may also be useful in treating hypotension and shock, hypotension during spinal anaesthesia, prolongation of spinal anaesthesia, paroxysmal supraventricular tachycardia, symptomatic relief of external or internal hemorrhoids, and to increase blood pressure as an aid in the diagnosis of heart murmurs.
