The query "M p t kit dose" likely refers to MPT kit — a combination chemotherapy regimen used in multiple myeloma (Melphalan + Prednisone + Thalidomide). Let me search the library.

Harrison's has a relevant section on MPT in multiple myeloma. Let me read that content.

Based on the textbook content, here is a concise answer on the MPT regimen (Melphalan + Prednisone + Thalidomide) for Multiple Myeloma:
MPT Regimen — Multiple Myeloma
MPT = Melphalan + Prednisone + Thalidomide
Standard Doses
| Drug | Dose | Schedule |
|---|---|---|
| Melphalan | 0.25 mg/kg/day (or 4 mg/m²/day) | Days 1–4, every 6 weeks |
| Prednisone | 2 mg/kg/day | Days 1–4, every 6 weeks |
| Thalidomide | 100–200 mg/day | Continuous (daily) |
Cycle length: 6 weeks, typically for 9–12 cycles.
Key Points
- Indication: Transplant-ineligible newly diagnosed multiple myeloma (older patients, physiologic age >70, significant comorbidities)
- MPT was historically a standard of care for non-transplant candidates, showing superior response and survival over MP (melphalan + prednisone) alone
- Now largely replaced by newer triplet regimens — according to Harrison's (2025): "with the availability of newer agents and combinations, MP-based combinations are now not utilized"
- Preferred current alternatives include DRd (daratumumab + lenalidomide + dexamethasone) and RVD-lite (bortezomib + lenalidomide + dexamethasone), which achieve overall response rates of 93% and 86%, respectively
Thalidomide Considerations in MPT
- Thalidomide requires VTE prophylaxis (aspirin or LMWH) due to thrombosis risk
- Peripheral neuropathy is a key dose-limiting toxicity — dose reduction may be needed
- Teratogenic — strict contraception mandatory

I have sufficient information from the textbooks. Here is the complete answer:
MTP (Medical Termination of Pregnancy) — Drug Doses
The standard medical abortion regimen uses Mifepristone + Misoprostol.
Regimen (≤9 weeks / ≤63 days gestation)
| Step | Drug | Dose | Route | Timing |
|---|---|---|---|---|
| Day 1 | Mifepristone | 200 mg | Oral (in clinic) | Day 1 |
| Day 2–3 | Misoprostol | 800 mcg | Buccal / Vaginal / Sublingual | 24–48 hours after mifepristone |
- Efficacy: ~99.6% for pregnancy termination at ≤9 weeks
- Buccal or vaginal misoprostol is preferred over oral — fewer side effects (nausea, fever, chills)
Regimen for >9 weeks (Second trimester)
- Mifepristone 200 mg orally, followed 36–48 hours later by
- Misoprostol 400 mcg buccal/sublingual every 3–4 hours (repeated doses until expulsion)
Alternative — Misoprostol Only (where mifepristone unavailable)
- Misoprostol 800 mcg vaginally or sublingually, repeated every 3–12 hours × 3 doses
- Lower efficacy (~80%) vs. combination regimen
Alternative — Methotrexate + Misoprostol (≤8 weeks)
- Methotrexate 50 mg/m² IM or orally, then
- Misoprostol 800 mcg vaginally 3–7 days later
- Works over weeks (slower than mifepristone regimen); also effective for early ectopic pregnancy
Key Points
| Rh-negative women | Give anti-D immunoglobulin 50 mcg (MICRhoGAM) within 72 hours |
| Follow-up | At 4–14 days — confirm complete abortion by USG or serial β-hCG (should drop ≥75%) |
| Incomplete abortion | Occurs in ~0.6–3% — managed with uterine aspiration |
| Heavy bleeding (>2 pads/hr × 2 hrs) | Emergency referral |
| Misoprostol | Teratogenic — if pregnancy continues, surgical termination needed |
