Array

NOT FOR INJECTION INTO THE EYE - FOR TOPICAL OPHTHALMIC USE ONLY

Prolonged use of a topical ocular anesthetic is not recommended. It may produce permanent corneal opacification with accompanying visual loss.

What are the precautions of Proparacaine Hydrochloride?

Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term studies in animals have not been performed to evaluate carcinogenic potential, mutagenicity or possible impairment of fertility in males or females.

Pregnancy

Pregnancy Category C

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when proparacaine hydrochloride is administered to a nursing woman.

Pediatric Use

Safety and effectiveness of proparacaine hydrochloride ophthalmic solution in pediatric patients have been established. Use of proparacaine hydrochloride is supported by evidence from adequate and well-controlled studies in adults and children over the age of twelve, and safety information in neonates and other pediatric patients.

Geriatric Use

No overall clinical differences in safety of effectiveness have been observed between the elderly and other adult patients.

What are the side effects of Proparacaine Hydrochloride?

Occasional temporary stinging, burning and conjunctival redness may occur with the use of proparacaine. A rare, severe, immediate-type, apparently hyperallergic corneal reaction characterized by acute, intense and diffuse epithelial keratitis, a gray, ground glass appearance, sloughing of large areas of necrotic epithelium, corneal filaments and sometimes iritis with descemetitis has been reported.

Allergic contact dermatitis from proparacaine with drying and fissuring of the fingertips has been reported.

Clinical Pharmacology

Proparacaine hydrochloride ophthalmic solution is a rapidly-acting topical anesthetic, with induced anesthesia lasting approximately 10-20 minutes.

Non-Clinical Toxicology

Proparacaine hydrochloride ophthalmic solution is contraindicated in patients with known hypersensitivity to any of the ingredients of this preparation.

NOT FOR INJECTION INTO THE EYE - FOR TOPICAL OPHTHALMIC USE ONLY

Prolonged use of a topical ocular anesthetic is not recommended. It may produce permanent corneal opacification with accompanying visual loss.

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.

Long-term studies in animals have not been performed to evaluate carcinogenic potential, mutagenicity or possible impairment of fertility in males or females.

Occasional temporary stinging, burning and conjunctival redness may occur with the use of proparacaine. A rare, severe, immediate-type, apparently hyperallergic corneal reaction characterized by acute, intense and diffuse epithelial keratitis, a gray, ground glass appearance, sloughing of large areas of necrotic epithelium, corneal filaments and sometimes iritis with descemetitis has been reported.

Allergic contact dermatitis from proparacaine with drying and fissuring of the fingertips has been reported.
