Active ingredients

The drug TONTERIN contains a combination of these active pharmaceutical ingredients (APIs):

1 Propyphenazone
UNII OED8FV75PY - PROPYPHENAZONE

Propyphenazone is a pyrazolone derivative with anti-inflammatory, analgesic and antipyretic activity. As it is structurally related to aminophenazone it has been associated with severe blood dyscrasias. However, it cannot be transformed into potentially carcinogenic nitrosamines and has therefore been widely used as a replacement drug for aminophenazone.

2 Vitamin B1
UNII M572600E5P - THIAMINE HYDROCHLORIDE

Thiamine pyrophosphate (TPP), the coenzymatic form of thiamine, is involved in two main types of metabolic reactions: decarboxylation of α-ketoacids (e.g. pyruvate, α-ketoglutarate and branched-chain keto acids) and transketolation (e.g. among hexose and pentose phosphates). Therefore, the principal physiological role of thiamine is as a coenzyme in carbohydrate metabolism, where TPP is required for several stages in the breakdown of glucose to provide energy.
