TIMOLOL MALEATE - TIMOLOL MALEATE SOLUTION PHYSICIANS TOTAL CARE, INC. ---------- TIMOLOL MALEATE OPHTHALMIC SOLUTION USP STERILE 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: [α] 25° in 1.0N HCl (C = 5%) = -12.2° ( -11.7° to -12.5°). 405 nm Its molecular formula is C H N O S•C H O and its structural formula is: 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 ophthalmic solution USP is stable at room temperature. Timolol maleate ophthalmic solution is supplied as a sterile, isotonic, buffered, aqueous solution of timolol maleate in two do sage strengths: Each mL of timolol maleate ophthalmic solution 0.25% contains 2.5 mg of timolol (3.4 mg of timolol maleate). Each mL of timolol maleate ophthalmic solution 0.5% contains 5.0 mg of timolol (6.8 mg of timolol maleate). Inactive ingredients: monobasic and dibasic sodium phosphate, sodium hydroxide to adjust pH (6.5 to 7.5), and purified water. Benzalkonium chloride 0.01% is added as preservative. CLINICAL PHARMACOLOGY MECHANISM OF ACTION Timolol maleate is a beta1 and beta2 (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 13 24 4 3 4 4 4 adequate cardiac function.
