Ganciclovir compositions and related methods
Gancyclovir formulations that are ready-to-use, substantially particulate free, and stable upon storage are disclosed. Methods of manufacture and administration of such compositions are also provided.
1. A stable, injectable, ready to administer, sterile, particulate-matter-free, aqueous parenteral dosage form for parenteral administration to a subject, consisting essentially of:
ganciclovir at a concentration of from 1 mg/ml to 3 mg/ml;
a tonicity agent; and
optionally a pH adjuster,
wherein the composition has a pH of from 5 to 9.
2. The parenteral dosage form of claim 1 , wherein the ganciclovir is present in an amount of from 1.5 mg/ml to 2.5 mg/ml.
3. The parenteral dosage form of claim 1 , wherein the ganciclovir is present in an amount of 2 mg/ml.
4. The parenteral dosage form of claim 1 , wherein the tonicity agent is a member selected from the group consisting of: sodium chloride, mannitol, sorbitol, dextrose, ethanol, glycerin, propylene glycol, and combinations thereof.
5. The parenteral dosage form of claim 1 , wherein the tonicity agent is sodium chloride.
6. The parenteral dosage form of claim 1 , wherein parenteral dosage form has a tonicity of from 250-350 mOsmol/Kg.
7. The parenteral dosage form of claim 1 , wherein the pH of the parenteral dosage form is 7.5.
8. The parenteral dosage form of claim 1 , wherein the pH adjuster is selected from the group consisting of: sodium hydroxide, potassium hydroxide, hydrochloric acid, sulfuric acid, cysteine, lysine, acetic acid, citric acid, ascorbic acid, salicylic acid, and combinations thereof.
9. The parenteral dosage form of claim 1 , wherein the pH adjuster is sodium hydroxide.
