*There is no treatment for [disease name]; the mainstay of therapy is supportive care.
The mainstay of treatment for Toxic multinodular goiter is [[Surgery]]. Patients with symptomatic [[hyperthyroidism]], sub-clinical [[hyperthyroid]] patients with expected compilations and patients refusing surgical therapy are treated with [[beta blockers]] and [[antithyroid|anti-thyroid pharmacological groups]].
*Supportive therapy for [disease name] includes [therapy 1], [therapy 2], and [therapy 3].
*The majority of cases of [disease name] are self-limited and require only supportive care.


*[Disease name] is a medical emergency and requires prompt treatment.

===Indications===
Symptomatic therapy for toxic multinodular goiter (TMG) is recommended for the patients with the following:<ref name="pmid3753814">{{cite journal| author=Laurberg P, Buchholtz Hansen PE, Iversen E, Eskjaer Jensen S, Weeke J| title=Goitre size and outcome of medical treatment of Graves' disease. | journal=Acta Endocrinol (Copenh) | year= 1986 | volume= 111 | issue= 1 | pages= 39-43 | pmid=3753814 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=3753814  }} </ref><ref>name="pmid1283983">{{cite journal| author=van Soestbergen MJ, van der Vijver JC, Graafland AD| title=Recurrence of hyperthyroidism in multinodular goiter after long-term drug therapy: a comparison with Graves' disease. | journal=J Endocrinol Invest | year= 1992 | volume= 15 | issue= 11 | pages= 797-800 | pmid=1283983 | doi=10.1007/BF03348807 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=1283983  }} </ref><ref name="pmid4107462">{{cite journal| author=Becker DV, Hurley JR| title=Complications of radioiodine treatment of hyperthyroidism. | journal=Semin Nucl Med | year= 1971 | volume= 1 | issue= 4 | pages= 442-60 | pmid=4107462 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=4107462  }} </ref>

Overview

The mainstay of treatment for Toxic multinodular goiter is Surgery. Patients with symptomatic hyperthyroidism, sub-clinical hyperthyroid patients with expected compilations and patients refusing surgical therapy are treated with beta blockers and anti-thyroid pharmacological groups.

Medical Therapy

Indications

Symptomatic therapy for toxic multinodular goiter (TMG) is recommended for the patients with the following:[1][2][3]

Pharmacological drug therapy

Following are drugs used in the symptomatic management of toxic multinodular goiter:

Following are antithyroid medicines used in the management of TMG:

Anti-thyroid therapy for toxic multinodular goiter (TMG) is recommended for the patients with the following:

Treatment of TMG should be decided on:

Drug Regimens

Pharmacological medical therapy for toxic multinodular goiter is primarily based on beta blockers and anti-thyroid drugs.[4]

  1. Toxic Multinodular Goiter
    • Hyperthyroidism[5]
    • Subclinical hyperthyroidism with comorbid conditions such as diabetes mellitus, heart failure or CNS abnormality[3]
      • Preferred regimen (1): Propylthiouracil 5-10 mg q24h PO for long term to avoid remission with 3 month review of TSH
      • Alternative regimen (1): Methimazole 5-10 mg q24h PO for long term to avoid remission with 3 month review of TSH
    • Subclinical hyperthyroidism without comorbid conditions
