  • No data
  • In a two-year study of dorzolamide hydrochloride administered orally to male and female Sprague-Dawley rats, urinary bladder papillomas were seen in male rats in the highest dosage group of 20 mg/kg/day (250 times the recommended human ophthalmic dose). Papillomas were not seen in rats given oral doses equivalent to approximately 12 times the recommended human ophthalmic dose. No treatment-related tumors were seen in a 21-month study in female and male mice given oral doses up to 75 mg/kg/day (~900 times the recommended human ophthalmic dose).
  • The increased incidence of urinary bladder papillomas seen in the high-dose male rats is a class-effu00a0ect of carbonic anhydrase inhibitors in rats. Rats are particularly prone to developing papillomas in response to foreign bodies, compounds causing crystalluria, and diverse sodium salts.
  • No changes in bladder urothelium were seen in dogs given oral dorzolamide hydrochloride for one year at 2 mg/kg/day (25 times the recommended human ophthalmic dose) or monkeys dosed topically to the eye at 0.4 mg/kg/day (~5 times the recommended human ophthalmic dose) for one year.
  • In a two-year study of timolol maleate administered orally to rats, there was a statistically significant increase in the incidence of adrenal pheochromocytomas in male rats administered 300 mg/kg/day (approximately 42,000 times the systemic exposure following the maximum recommended human ophthalmic dose). Similar diu00a0fferences were not observed in rats administered oral doses equivalent to approximately 14,000 times the maximum recommended human ophthalmic dose.
  • In a lifetime oral study of timolol maleate in mice, there were statistically significant increases in the incidence of benign and malignant pulmonary tumors, benign uterine polyps and mammary adenocarcinomas in female mice at 500 mg/kg/day, (approximately 71,000 times the systemic exposure following the maximum recommended human ophthalmic dose), but not at 5 or 50 mg/kg/day (approximately 700 or 7,000, respectively, times the systemic exposure following the maximum recommended human ophthalmic dose). In a subsequent study in female mice, in which post-mortem examinations were limited to the uterus and the lungs, a statistically significant increase in the incidence of pulmonary tumors was again observed at 500 mg/kg/day.
  • The increased occurrence of mammary adenocarcinomas was associated with elevations in serum prolactin which occurred in female mice administered oral timolol at 500 mg/kg/day, but not at doses of 5 or 50 mg/kg/day. An increased incidence of mammary adenocarcinomas in rodents has been associated with administration of several other therapeutic agents that elevate serum prolactin, but no correlation between serum prolactin levels and mammary tumors has been established in humans. Furthermore, in adult human female subjects who received oral dosages of up to 60 mg of timolol maleate (the maximum recommended human oral dosage), there were no clinically meaningful changes in serum prolactin.
  • The following tests for mutagenic potential were negative for dorzolamide: (1) (mouse) cytogenetic assay; (2) chromosomal aberration assay; (3) alkaline elution assay; (4) V-79 assay; and (5) Ames test.
  • Timolol maleate was devoid of mutagenic potential when tested (mouse) in the micronucleus test and cytogenetic assay (doses up to 800 mg/kg) and in a neoplastic cell transformation assay (up to 100 mcg/mL). In Ames tests the highest concentrations of timolol employed, 5,000 or 10,000 mcg/plate, were associated with statistically significant elevations of revertants observed with tester strain TA100 (in seven replicate assays), but not in the remaining three strains. In the assays with tester strain TA100, no consistent dose response relationship was observed, and the ratio of test to control revertants did not reach 2. A ratio of 2 is usually considered the criterion for a positive Ames test.
  • Reproduction and fertility studies in rats with either timolol maleate or dorzolamide hydrochloride demonstrated no adverse effu00a0ect on male or female fertility at doses up to approximately 100 times the systemic exposure following the maximum recommended human ophthalmic dose.
  • Clinical studies of 3 to 15 months duration were conducted to compare the IOP-lowering effu00a0ect over the course of the day of dorzolamide hydrochloride and timolol maleate ophthalmic solution twice daily (dosed morning and bedtime) to individually and concomitantly administered 0.5% timolol twice daily and 2% dorzolamide twice and three times daily. The IOP-lowering eu00a0ffect of dorzolamide hydrochloride and timolol maleate ophthalmic solution twice daily was greater (1 to 3 mmHg) than that of monotherapy with either 2% dorzolamide three times daily or 0.5% timolol twice daily. The IOP-lowering eu00a0ffect of dorzolamide hydrochloride and timolol maleate ophthalmic solution twice daily was approximately 1 mmHg less than that of concomitant therapy with 2% dorzolamide three times daily and 0.5% timolol twice daily.
  • Open-label extensions of two studies were conducted for up to 12 months. During this period, The IOP lowering eu00a0ffect of dorzolamide hydrochloride and timolol maleate ophthalmic solution twice daily was consistent during the 12 month follow-up period.

  • Advise the patient to read the FDA-Approved Patient Labeling (Patient Information and Instructions for use).
  • Potential for Exacerbation of Asthma and COPD
  • Dorzolamide hydrochloride and timolol maleate ophthalmic solution may cause severe worsening of asthma and COPD symptoms including death due to bronchospasm.

  • Potential of Cardiovascular Effects
  • Dorzolamide hydrochloride and timolol maleate ophthalmic solution may cause worsening of cardiac symptoms. Advise patients with sinus bradycardia, second or third degree atrioventricular block, or cardiac failure not to take this product. .
  • Sulfonamide Reactions
  • Dorzolamide hydrochloride and timolol maleate ophthalmic solution contains dorzolamide (which is a sulfonamide) and, although administered topically, is absorbed systemically. Therefore the same types of adverse reactions that are attributable to sulfonamides may occur with topical administration, including severe skin reactions. Advise patients that if serious or unusual reactions or signs of hypersensitivity occur, they should discontinue the use of the product and seek their physician's advice. .
  • Handling Ophthalmic Solutions
  • Instruct patients that ocular solutions, if handled improperly or if the tip of the dispensing container contacts the eye or surrounding structures, can become contaminated by common bacteria known to cause ocular infections. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions. .
  • Intercurrent Ocular Conditions
  • Advise patients that if they have ocular surgery or develop an intercurrent ocular condition (e.g., trauma or infection), they should immediately seek their physician's advice concerning the continued use of the present multidose container.
  • Concomitant Topical Ocular Therapy
  • If more than one topical ophthalmic drug is being used, the drugs should be administered at least five minutes apart.
  • Contact Lens Use
  • Advise patients that dorzolamide hydrochloride and timolol maleate ophthalmic solution contains benzalkonium chloride which may be absorbed by soft contact lenses. Contact lenses should be removed prior to administration of the solution. Lenses may be reinserted 15 minutes following administration of dorzolamide hydrochloride and timolol maleate ophthalmic solution.
