PLIAGLIS
Overview
What is PLIAGLIS?
PLIAGLIS (lidocaine and tetracaine) Cream 7% / 7% is a topical local anesthetic cream that forms a pliable peel on the skin when exposed to air. The drug formulation is an emulsion in which the oil phase is a 1:1 eutectic mixture of lidocaine 7% and tetracaine 7%. The eutectic mixture has a melting point below room temperature and therefore both local anesthetics exist as a liquid oil rather than as crystals.
The net weight of lidocaine is 2.1 g and of tetracaine is 2.1 g per 30 g tube.
Lidocaine, an amide local anesthetic, is chemically designated as acetamide,2-(diethylamino)-N-(2,6-dimethylphenyl) and has an octanol:water partition ratio of 182 at pH 7.3.
The molecular weight of lidocaine is 234.3, and the molecular formula is CHNO. The structural formula is:
Tetracaine, an ester local anesthetic, is chemically designated as 2-dimethylaminoethyl 4-n-butyl-aminobenzoate and has an octanol:water partition ratio of 5370 at pH 7.3. The molecular weight of tetracaine is 264.4, and the molecular formula is CHNO. The structural formula is:
Each gram of PLIAGLIS contains lidocaine 70 mg and tetracaine 70 mg in a 1:1 eutectic mixture and it also contains the following inactive ingredients: dibasic calcium phosphate, methylparaben, petrolatum, polyvinyl alcohol, propylparaben, purified water, and sorbitan monopalmitate.

Cream: 70 mg of lidocaine and 70 mg of tetracaine per gram (7%; 7%). ()
What should I talk to my health care provider before I take PLIAGLIS?
How should I use PLIAGLIS?
PLIAGLIS is indicated for use on intact skin in adults to provide topical local analgesia for superficial dermatological procedures such as dermal filler injection, pulsed dye laser therapy, facial laser resurfacing, and laser-assisted tattoo removal.
Apply only to intact skin. ()
Do not exceed the recommended dose of drug or duration of application. ()

What might happen if I take too much PLIAGLIS?
Application of 59 g of PLIAGLIS over 400 cm for up to 120 minutes to adults produces peak plasma concentrations of lidocaine of 220 ng/mL. Toxic levels of lidocaine (>5000 ng/mL) cause CNS toxicity, including the risk of seizure. Signs of CNS toxicity may start at plasma concentrations of lidocaine as low as 1000 ng/mL, and the risk of seizures generally increases with increasing plasma levels. Very high levels of lidocaine can cause respiratory arrest, coma, decreases in cardiac output, total peripheral resistance and mean arterial pressure, ventricular arrhythmias and cardiac arrest.
Tetracaine is associated with a profile of systemic CNS and cardiovascular adverse events similar to lidocaine, although toxicity associated with tetracaine is thought to occur at lower doses compared to lidocaine. The toxicity of co-administered local anesthetics is thought to be at least additive. In the absence of massive topical overdose or oral ingestion, other etiologies for the clinical effects or overdosage from other sources of lidocaine, tetracaine or other local anesthetics should be considered. The management of overdosage includes close monitoring, supportive care and symptomatic treatment. Dialysis is of negligible value in the treatment of acute overdosage of lidocaine or tetracaine.

Clinical Information
Chemical Structure
No Image foundClinical Pharmacology
Lidocaine is an amide-type local anesthetic agent and tetracaine is an ester-type local anesthetic agent. Both lidocaine and tetracaine block sodium ion channels required for the initiation and conduction of neuronal impulses which, in certain instances, results in local anesthesia. When applied to intact skin, PLIAGLIS provides local dermal analgesia by the release of lidocaine and tetracaine from the peel into the skin.
Non-Clinical Toxicology
Known history of sensitivity to lidocaine or tetracaine, or local anesthetics of the amide or ester type. ()Para-aminobenzoic acid (PABA) hypersensitivity. ()
Nimodipine is metabolized via the cytochrome P450 3A4 system located both in the intestinal mucosa and in the liver. Drugs that are known to either inhibit or to induce this enzyme system may therefore alter the first pass or the clearance of nimodipine.
In addition, the blood pressure lowering effects of antihypertensives could be enhanced when taken concomitantly with nimodipine.
Inducers of CYP3A4
Nimodipine plasma concentration and efficacy may be significantly reduced when concomitantly administered with strong CYP3A4 inducers. Therefore strong CYP3A4 inducers (e.g. rifampin, carbamazepine, phenobarbital, phenytoin, St. John’s Wort) should generally not be administered concomitantly with nimodipine (See ).
Other moderate and weak inducers of CYP3A4 may also reduce the efficacy of nimodipine, although the magnitude of decrease in nimodipine plasma concentrations is not known. Patients on these should be closely monitored for lack of effectiveness, and a nimodipine dosage increase may be required. Moderate and weak CYP3A4 inducers include: amprenavir, aprepitant, armodafinil, bosentan, efavirenz, etravirine, Echinacea, modafinil, nafcillin, pioglitazone, prednisone and rufinamide.
Inhibitors of CYP3A4
Nimodipine plasma concentration can be significantly increased when concomitantly administered with strong inhibitors of the CYP3A4 system. As a consequence, the blood pressure lowering effect may be increased. Therefore strong CYP3A4 inhibitors should not be coadministered with nimodipine (See ). Strong CYP3A4 inhibitors include some members of the following classes:
Nimodipine plasma concentration can also be increased in the presence of moderate and weak inhibitors of CYP3A4. If nimodipine is concomitantly administered with these drugs, blood pressure should be monitored, and a reduction of the nimodipine dose may be necessary. Moderate and weak CYP3A4 inhibitors include amprenavir, aprepitant, atazanavir, amiodarone, alprozalam, cyclosporine, cimetidine, erythromycin, fluconazole, fluoxetine, isoniazid, oral contraceptives, quinuprestin/dalforpristin, and valproic acid.
Blood pressure lowering drugs
Nimodipine may increase the blood pressure lowering effect of concomitantly administered anti-hypertensives, such as:
Blood pressure should be carefully monitored, and dose adjustment of the blood pressure lowering drug(s) may be necessary.
