Ticarcillin (also known as Ticar) is a semisynthetic antibiotic with a broad spectrum of bactericidal activity against many gram-positive and gram-negative aerobic and anaerobic bacteria. Ticarcillin is not absorbed orally; therefore, it must be given intravenously or intramuscularly. Ticarcillin's antibiotic properties arise from its ability to prevent cross-linking of peptidoglycan during cell wall synthesis when the bacteria tries to divide, causing death. Usage of ticar was discontinued.

Sample Use Guides
Bacterial septicemia: 200 to 300 mg/kg/day by I.V. infusion in divided doses every 4 or 6 hours.
Respiratory tract infections: (The usual dose is 3 grams given every 4 hours [18 grams/day] or 4 grams given every 6 hours [16 grams/day] depending on weight and the severity of the infection.)
Urinary tract infections: Complicated: 150 to 200 mg/kg/day by I.V. infusion in divided doses every 4 or 6 hours. (Usual recommended dosage for average [70 kg] adults: 3 grams q.i.d.)
Uncomplicated: 1 gram I.M. or direct I.V. every 6 hours.

A total of 632 clinical bacterial isolates were tested for susceptibility to twofold dilutions of ticarcillin alone and in combination with 1, 2, and 4 micrograms of clavulanic acid (CA) (Timentin) per ml by a reference microdilution method. With the addition of CA, ticarcillin MICs were reduced eightfold or greater with 54 of 59 (92%) strains of the family Enterobacteriaceae with ticarcillin MICs of greater than or equal to 64 micrograms/ml. Ticarcillin MICs for beta-lactamase-producing Haemophilus influenzae, Neisseria gonorrhoeae, and most Staphylococcus aureus were reduced to less than or equal to 0.5 micrograms/ml when CA was added.
