The Ministry of Health and Family Welfare, Government of India has recently prohibited the manufacture for sale, sale or distribution for human use of 328 fixed dose combinations (FDCs) with immediate effect, including FDCs in diabetes.
All of us have read the Government’s notification on FDCs and it has generated some confusion and also raised several questions as to what is allowed and what is not allowed.
Let us talk about the rationality of use of FDCs in diabetes.
Type 2 diabetes is a progressive disease, characterized by insulin resistance and β-cell dysfunction. As the disease runs its course, the initial oral hypoglycemic agent (OHA) prescribed may lose its efficacy leading to inadequate glycemic control, which requires sequential addition of a second or even a third drug belonging to a different class of OHAs, to achieve target or desired glycemic control.
Combination therapy administered as separate medications may deter patient from adhering to the prescribed treatment.
Combining two or more OHAs as a single-dose fixed-dose combinations (FDCs) therefore improves treatment adherence by minimizing medication burden to the patient and also reduces costs of treatment, which is a very important consideration, given that out of pocket expenditure on health is amongst the highest in India.
A widely used FDC in diabetes is the combination of glimepiride, metformin and pioglitazone in two strengths: lower strength (7.5 mg) & higher strength (15 mg).
Triple drug combinations reduced A1c to a greater extent than two drugs in a systematic review and meta-analysis of randomized controlled trials, which examined the addition of a third agent after dual therapy failure in patients inadequately controlled with two agents (predominantly metformin and a sulfonylurea or metformin and a thiazolidinedione),. In trials lasting 52 to 54 weeks, addition of thiazolidinediones, GLP-1 receptor agonists, or SGLT2 inhibitors to metformin and sulfonylurea reduced A1c to a similar extent (Diabetes Obes Metab. 2018 Apr;20(4):985-997).
It is important to note that the Govt. notification also says, “It has also “restricted” the manufacture, sale or distribution of six FDCs“subject to certain conditions”.
The Govt. of India’s notification has recommended the discontinuation of only the FDCs containing lower strength of pioglitazone because of inadequate published international literature, but has allowed the FDC of glimepiride and metformin with pioglitazone in higher strength (15mg).
The notification has not questioned the safety and efficacy of the three molecules. The only issue raised is use of a particular strength of the molecule.
Anti-diabetic triple FDCs containing glimepiride, metformin with high dose pioglitazone are approved by DCGI and all patients can be continued on the existing medication.
In case a patient happens to be on the FDC containing the lower strength of pioglitazone (7.5mg), he should be evaluated again.
