Brand name
TEMOPEN
Antimicrobial activity
Because it is hydrolyzed less rapidly than ampicillin, non-β-
lactamase-producing strains of N. gonorrhoeae, ampicillin-susceptible
H. influenzae and some Enterobacteriaceae are susceptible.
Most aerobic and anaerobic Gram-positive bacteria are susceptible,
with the exception of E. faecalis and β-lactamase-producing
Staph. aureus. Anaerobic Gram-negative bacteria including B. fragilis
are usually susceptible. Bactericidal synergy with aminoglycosides
is demonstrable against Ps. aeruginosa and enterobacteria.
Acquired resistance
Ticarcillin is generally cross-resistant with carbenicillin.
It is somewhat stable to hydrolysis by AmpC-mediated β-lactamases of Gram-negative bacilli, but can be hydrolyzed
by most other chromosomally and plasmid-mediated enzymes
unless protected by a β-lactamase inhibitor.
Pharmacokinetics
Oral absorption: Negligible
Cmax 1 g intramuscular: 35 mg/L after 1 h
Plasma half-life: 1.3 h
Volume of distribution: 0.21 L/kg
Plasma protein binding: 50–60%
Absorption and distribution
It is not orally absorbed. On parenteral co-administration
with gentamicin, the plasma concentration of ticarcillin is
unaffected, but the concentration of gentamicin is lowered. It
enters the serous fluids, providing concentrations up to 60%
of those of the plasma. It does not cross the normal meninges
but levels of up to 50% of those of the plasma can be found
in meningitis.
Metabolism and excretion
Up to 15% is excreted as penicilloic acid, a higher percentage
than for carbenicillin (up to 5%). Some is excreted in
the bile, producing levels 2–3 times those in the plasma, but
the main route of excretion is through the kidneys (80%),
principally as unchanged drug, appearing in the urine in the
first 6 h. It is more rapidly eliminated in children with cystic
fibrosis.
Clinical Use
Serious infection, including septicemia, respiratory tract infections,
genitourinary tract infections and skin and soft-tissue infections caused
by susceptible bacteria
Side effects
As with all penicillins, hypersensitivity reactions may occur,
but are less frequent and severe than those associated with
benzylpenicillin. Rashes and eosinophilia occur; reversible
abnormalities of liver function can develop. Since large doses
of the drug have to be used, convulsions can occur, as with
other penicillins, and being a disodium salt, electrolyte disturbances
can result from the sodium load and from loss of
potassium.
Synthesis
Ticarcillin, [2S-(2α,5α,6β)]-3,3-dimethyl-7-oxo-6-[2-carboxy-2-(3-thienyl)
acetamido]-4-thia-1-azabicyclo[3.2.0]-heptan-2-carboxylic acid (32.1.1.34), is synthesized by direct acylation of 6-APA in the presence of sodium hydroxide, but with
3-thienylmalonic acid chloride (32.1.1.33), which gives ticarcillin.
Check Digit Verification of cas no
The CAS Registry Mumber 34787-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34787-01:
(7*3)+(6*4)+(5*7)+(4*8)+(3*7)+(2*0)+(1*1)=134
134 % 10 = 4
So 34787-01-4 is a valid CAS Registry Number.

Therapeutic methods and compositions using deuterated enriched 2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylic acid 3-ethyl 5-methyl ester and other deuterated dihydropyridine compounds are described. The deuterated compounds exhibit enhanced efficacy in blocking calcium channels over non-deuterated dihydropyridines.
Enhancement of pharmaceutical activity
-
, (2008/06/13)
The invention encompasses mixtures of antimicrobial agents coencapsulated in liposomes which when administered in vivo exert an enhanced therapeutic effect. The therapeutic effectiveness of the coencapsulated antimocrobial agents is greater than that of the same combination administered either in solution or as a mixture of liposome populations each containing one of the antimicrobial agents.
