Tigi
Tigi Uses, Dosage, Side Effects, Food Interaction and all others data.
Tigi, a glycylcycline, inhibits protein translation in bacteria by binding to the 30S ribosomal subunit and blocking entry of amino-acyl tRNA molecules into the A site of the ribosome. This prevents incorporation of amino acid residues into elongating peptide chains. Tigi carries a glycylamido moiety attached to the 9-position of minocycline. The substitution pattern is not present in any naturally occurring or semisynthetic tetracycline and imparts certain microbiologic properties to tigecycline. Tigi is not affected by the two major tetracycline resistance mechanisms, ribosomal protection and efflux. Accordingly, tigecycline has demonstrated in vitro and in vivo activity against a broad spectrum of bacterial pathogens. There has been no cross resistance observed between tigecycline and other antibiotics. Tigi is not affected by resistance mechanisms such as beta-lactamases (including extended spectrum beta-lactamases), target site modifications, macrolide efflux pumps or enzyme target changes (e.g. gyrase/topoisomerase). In vitro studies have not demonstrated antagonism between tigecycline and other commonly used antibacterial drugs. In general, tigecycline is considered bacteriostatic.
Tigi is the first clinically-available drug in a new class of antibiotics called the glycylcyclines. Glycylcyclines are a new class of antibiotics derived from tetracycline. These tetracycline analogues are specifically designed to overcome two common mechanisms of tetracycline resistance, namely resistance mediated by acquired efflux pumps and/or ribosomal protection. Glycylcycline antibiotics have a similar mechanism of action as tetracycline antibiotics. Both classes of antibiotics bind to the 30S ribosomal subunit to prevent the amino-acyl tRNA from binding to the A site of the ribosome. However, the glycylcyclines appear to bind more effectively than the tetracyclines.

Dosage
Tigi dosage
The duration of therapy should be guided by the severity and site of the infection and the patient's clinical and bacteriological progress. The recommended duration of treatment with Tigi for complicated skin and skin structure infections or for complicated intra-abdominal infections is 5 to 14 days and for community-acquired bacterial pneumonia is 7 to 14 days. The recommended daily dose is as follows:
Adults: The recommended dosage regimen for Tigi is an initial dose of 100 mg, followed by 50 mg every 12 hours. Intravenous (IV) infusions of Tigi should be administered over approximately 30 to 60 minutes every 12 hours.
Pediatric use: Safety and effectiveness in pediatric patients below the age of 18 years have not been established.
Geriatric use: No unexpected overall differences in safety or effectiveness were observed between these subjects and younger subjects.
Each vial of Tigi should be reconstituted with 5.3 ml of 0.9% Sodium Chloride Injection to achieve a concentration of 10 mg/ml of Tigi. The vial should be gently swirled until the drug dissolves. Withdraw 5 ml of the reconstituted solution from the vial and add to a 100 ml intravenous bag of 0.9% Sodium Chloride or 5% Dextrose for infusion (for a 100 mg dose, reconstitute two vials; for a 50 mg dose, reconstitute one vial). The maximum concentration of IV solution should be 1 mg/ml. If the same intravenous line is used for sequential infusion of several drugs, the line should be flushed before and after infusion of Tigi with either 0.9% Sodium Chloride Injection or 5% Dextrose Injection. Tigi is compatible with the following IV fluid: 0.9% Sodium Chloride Injection, 5% Dextrose Injection, Lactated Ringer’s Injection.
Side Effects
The most common treatment-emergent adverse events are nausea and vomiting which generally occurre during the first 1-2 days of therapy.
The following drug-related adverse events are reported infrequently in patients receiving Tigi: Injection site inflammation & pain, septic shock, allergic reaction, chills, thrombophlebitis, bradycardia, tachycardia, vasodilatation, anorexia, dry mouth, hypoglycemia, hyponatremia, prolonged prothrombin time, eosinophilia, thrombocytopenia, vaginal moniliasis, vaginitis, leukorrhea.
Toxicity
Since glycylcyclines are similar to tetracyclines, they share many of the same side effects and contraindications as tetracyclines. These side effects may include nausea/vomiting, headache, photosensitivity, discoloration of growing teeth, and fetal damage.
Precaution
Tigi is structurally similar to Tetracycline-class antibiotics and should be administered with caution in patients with known hypersensitivity to Tetracycline-class antibiotics
Interaction
Drug interaction of Tigi with Digoxin and Warfarin is observed.

Pregnancy & Breastfeeding use
Pregnancy: Tigi should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Lactation: Caution should be exercised when Tigi is administered to a nursing woman.
Contraindication
Tigi is contraindicated for use in patients who have known hypersensitivity to Tigi.
Acute Overdose
No specific information is available on the treatment of overdosage with Tigi. Intravenous administration of Tigi at a single dose of 300 mg over 60 minutes in healthy volunteers resulted in an increased incidence of nausea and vomiting.
Storage Condition
Prior to reconstitution, Tigi should be stored at 20°C to 25°C. Once reconstituted, Tigi may be stored at room temperature for up to 24 hours (up to 6 hours in the vial and the remaining time in the intravenous bag). Reconstituted solution may be stored refrigerated at 2°C to 8°C for up to 48 hours following immediate transfer of reconstituted solution into the intravenous bag.
