Therapeutic Group: Anti Bacterial


Tinobac 2 gm IM Injection: Each vial contains sterile powder of Spectinomycin Hydrochloride USP equivalent to Spectinomycin 2 gm.


Tinobac Sterile Powder contains Spectinomycin Hydrochloride which is an aminocyclitol antibiotic produced by a species of soil microorganism designated as Streptomyces spectabilis.


Spectinomycin Hydrochloride is an inhibitor of protein synthesis in the bacterial cell; the site of action is the 30S ribosomal subunit. In vitro studies have shown Spectinomycin Hydrochloride to be active against most strains of Neisseria gonorrhoeae


Tinobac Sterile Powder is indicated in the treatment of:

Acute gonorrheal urethritis and proctitis in the male

Acute gonorrheal cervicitis and proctitis in the female

Men and women with known recent exposure to gonorrhea should be treated as those known to have gonorrhea.

Dosage & Administration

Tinobac Sterile Powder, 2 grams: reconstitute with 3.2 ml of the accompanying water for injection with 0.9% Benzyl alcohol. Shake vials vigorously immediately after adding diluent and before withdrawing dose.

Intramuscular injections should be made deep into the upper outer quadrant of the gluteal muscle.
Adults (Men and Women)-Inject 5 ml intramuscularly for a 2 gm dose.This is also the recommended dose for patients being treated after failure of previous antibiotic therapy

Side Effects

The following reactions were observed during the single dose clinical trials: soreness at the injection site, urticaria, dizziness, nausea, chills, fever and insomnia


The usual precautions should be observed with atopic individuals. Prescribing Spectinomycin Sterile Powder in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria

Use in Pregnancy & Lactation

Pregnancy Category B. Since there are no controlled studies of Spectinomycin in pregnant women, and because animal reproduction studies are not always predictive of human responses, Spectinomycin should be used during pregnancy only if clearly needed.

Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Spectinomycin is administered to a nursing woman.
Pediatric Use
Safety and effectiveness in the pediatric population have not been established.
