Abbreviated New Drug Application
TIMOLOL MALEATE- TIMOLOL MALEATE SOLUTION/ DROPS FDC LIMITED ---------- STERILE OPHTHALMIC SOLUTION TIMOLOL MALEATE OPHTHALMIC SOLUTION USP 0.25% AND 0.5% DESCRIPTION Timolol maleate ophthalmic solution is a non-selective beta-adrenergic receptor blocking agent. Its chemical name is (-)-1-(_tert_-butylamino)-3-[(4-morpholino-1,2,5-thiadiazol-3-yl)oxy]-2-propanol maleate (1:1) (salt). Timolol maleate possesses an asymmetric carbon atom in its structure and is provided as the levo-isomer. The optical rotation of Timolol maleate is: Its molecular formula is C H N O S•C H O and its structural formula is: IMAG E Timolol maleate has a molecular weight of 432.50. It is a white, odorless, crystalline powder which is soluble in water, methanol, and alcohol. Timolol Maleate is stable at room temperature. Timolol Maleate Ophthalmic Solution is supplied as a sterile, isotonic, buffered, aqueous solution of Timolol maleate in two dosage strengths: Each mL of Timolol Maleate Ophthalmic Solution 0.25% contains 2.5 mg of timolol (3.4 mg of Timolol Maleate). The pH of the solution is approximately 7.0, and the osmolarity is 274-328 mOsm. Each mL of Timolol Maleate Ophthalmic Solution 0.5% contains 5 mg of timolol (6.8 mg of timolol maleate). Inactive ingredients: monobasic and dibasic sodium phosphate, sodium chloride, sodium hydroxide to adjust pH, and water for injection. Benzalkonium chloride 0.01% is added as preservative. CLINICAL PHARMACOLOGY MECHANISM OF ACTION Timolol maleate is a beta and beta (non-selective) adrenergic receptor blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. Beta-adrenergic receptor blockade reduces cardiac output in both healthy subjects and patients with heart disease. In patients with severe impairment of myocardial function, beta-adrenergic receptor blockade may inhibit the stimulatory effect of the sympathetic nervous system necessary to maintain adequate cardiac function.
