Tractoni (Larotrectinib) 100mg×30 Capsules | Ziska Bangladesh NTRK Fusion | GLT

Generic Information: Tractoni (Larotrectinib) — Ziska Pharmaceuticals, Bangladesh

Tractoni is the larotrectinib capsule of Ziska Pharmaceuticals Ltd., the Dhaka-based manufacturer whose export portfolio spans several precision oncology molecules. The presentation is a single strength — 100 mg capsules in a 30-capsule bottle — aimed squarely at the standard adult dose of 100 mg twice daily. Keeping the range to one strength is a deliberate simplification: each bottle is a fifteen-day supply at the standard dose, which makes ordering and inventory predictable for both individual patients and institutional buyers.

What Is Tractoni (Larotrectinib) Used For?

Tractoni is indicated for adult and pediatric patients with solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, that are metastatic or where surgery would likely cause severe morbidity, and who have no satisfactory alternative or whose disease has progressed after treatment. The indication is fusion-based rather than organ-based, covering infantile fibrosarcoma, salivary gland tumors, soft-tissue sarcoma, thyroid cancer, lung cancer and other NTRK fusion-positive cancers once testing confirms the fusion.

How Does Tractoni (Larotrectinib) Work?

Larotrectinib is a selective, ATP-competitive inhibitor of the tropomyosin receptor kinase (TRK) family — TRKA, TRKB and TRKC, encoded by the NTRK1, NTRK2 and NTRK3 genes. An NTRK fusion generates a constitutively active TRK fusion protein that drives tumor growth; by blocking all three TRK kinases, larotrectinib removes that driver and shrinks tumors across tissue types. The capsule uses the same sulfate salt formulation as the originator and is taken orally.

Indications of Tractoni (Bangladesh Label)

The Bangladesh label mirrors the originator: NTRK fusion-positive solid tumors without acquired resistance, locally advanced or metastatic or high-risk-for-surgery, and no satisfactory alternative or progression after prior therapy. Patient selection is the crux — a validated test must confirm the fusion, because larotrectinib has minimal activity in fusion-negative tumors and in those carrying the acquired TRK resistance mutations such as G595R in TRKA.

Dosage and Administration

The recommended dose is 100 mg orally twice daily for adults and children with body surface area of at least 1.0 m², with or without food, continued until progression or unacceptable toxicity; children below 1.0 m² receive 100 mg/m² twice daily. Capsules are swallowed whole and must not be chewed or crushed. Toxicity reductions step through 75 mg and 50 mg twice daily to 100 mg once daily before discontinuation, and coadministration of strong CYP3A4 inhibitors or inducers requires dose adjustment.

Side Effects of Tractoni

The common reactions, in at least 20% of patients, are fatigue, nausea, dizziness, vomiting, cough, constipation, diarrhea and raised AST and ALT. Neurotoxicity deserves particular attention — dizziness, cognitive impairment, mood changes and sleep disturbance — with advice against driving or operating machinery while affected. Hepatotoxicity is managed with liver-function tests every two weeks for the first two months and monthly thereafter, and the drug can cause fetal harm, so contraception is required during and for one week after treatment.

Storage Instructions

Store the 30-capsule bottle at room temperature in a closed container protected from moisture, out of children's reach. Ziska's Bangladesh stock ships with batch numbers and a certificate of analysis, giving buyers a verifiable provenance for a generic that travels internationally — a real safeguard against the counterfeit risk that attends high-value oncology drugs in transit.

FAQ

Why only a 100 mg strength? Tractoni focuses on the standard adult dose of 100 mg twice daily; each 30-capsule bottle is a fifteen-day supply at that dose.

Is it the same as Vitrakvi? Same active ingredient and dose; Tractoni is the Ziska Bangladesh generic at a lower price.

Does it need a gene test? Yes — NTRK fusion must be confirmed by a validated test before treatment.

Is it chemotherapy? No, it is an oral targeted TRK inhibitor, not a cytotoxic agent.

Can children take it? Yes, with body-surface-area-based dosing.
