The thioamide class of antithyroid drugs has been associated with the development of hypoprothrombinemia. Two drugs in this class, propylthiouracil and methimazole, resemble the methyltetrazole-thiol leaving group of certain cephalosporin antibiotics. Both were found in vitro to inhibit the vitamin K dependent step in clotting factor synthesis, the gamma-carboxylation of glutamic acid with 50 per cent inhibitory concentrations of 2 mM for propylthiouracil and 0.1 mM for methimazole. Methimazole…

All cats treated with methimazole should be monitored with BUN and creatinine, in addition to serum T4, complete blood count, and liver enzymes, and moderate to severe hypertension should be treated concurrently with-atenolol, amlodipine, or an ACE inhibitor.

Cirrhosis‐induced pseudoglucagonoma syndrome in a patient with Type 2 Diabetes: an autopsy study
It is worth noting that the patient suffered from irondeficiency anaemia already on initial presentation, indicating that pre-existing gastrointestinal disease may have contributed to the severe gastrointestinal haemorrhage following antithyroid treatment.
Long-term propylthiouracil use and acute myeloid leukemia: A case report and review of the literature
A 31-year-old female who had been administered propylthiouracil for 15 years and shortly after delivery developed acute myeloid leukemia with complex karyotype, including a rare t(2;21) translocation.
Antithyroid medications and psychosis
Patients who develop mental disorders while under ATD should be followed by an accurate evaluation of TSH, free triiodothyronine (FT3), and free thyroxine ( FT4) levels throughout the course of the psychiatric disease.
Severe gastrointestinal haemorrhage after methimazole intake
A 65-year-old patient admitted to the emergency room (ER) for palpitations and readmitted to the ER for fatigue, tachycardia and melaena, where he was discharged on day 7, with the diagnosis of Graves’ disease.
Metal-induced B-H bond activation: reactions between half-sandwich Ir and Rh complexes with carboranylthioamide.
Novel half-sandwich metal (Ir, Rh) complexes constructed from carboranylthioamide ligands containing an unexpected metal-boron bond were synthesized and characterized. The strong base n-butyllithium
Gene expression profiling in rat liver treated with various hepatotoxic-compounds inducing coagulopathy.
It is concluded that these probe sets could be a good starting point in developing mechanism-based biomarkers for diagnosis or prognosis of hepatotoxicity-related coagulation abnormalities in the early stage of drug development.


Antibiotic-associated hypoprothrombinemia: a review of prospective studies, 1966-1988.
Patients at high risk for coagulopathy should be carefully monitored and serious consideration should be given to the use of prophylactic vitamin K in such cases, according to the hypothesis that the NMTT side chain is primarily responsible for hypoprothrombinemia.
Deficiency of prothrombin and proconvertin after therapy with propylthiouracil.
Observations on two patients have suggested a similarity between this apparently rare reaction to propylthiouracil and the therapeutic response to bishydroxycoumarin (Dicumarol), which appears to be a serious but little-known complication of the use of the latter drug.
Production of hypoprothrombinemia by moxalactam and 1-methyl-5-thiotetrazole in rats
To determine whether the hypoprothrombinemia associated with antibiotics containing a 1-methyl-5-thiotetrazole (MTT) group is a result of the presence of the MTT group, rats were maintained on a

The in vitro observations presented here and a closer examination of the clinical evidence raise the possibility that MTT-containing antibiotic-induced hypoprothrombinemia may not be a vitamin K reversible phenomenon and suggest that a slowly formed metabolite of MTT may be directly responsible for the observed inhibition.
