India's apex drug regulator, the Central Drug Standard Control Organisation (CDSCO), has recently approved tirzepatide, a medication developed by pharmaceutical giant Eli Lilly. This drug is known for its effectiveness in managing type 2 diabetes and obesity. While tirzepatide is currently imported and marketed in India for diabetes treatment, its potential approval for weight loss is eagerly awaited.
A Breakthrough in Diabetes and Weight Loss Management
Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. It mimics the effects of these naturally occurring hormones to help regulate blood sugar levels. This medication is sold under the brand names Mounjaro for diabetes management and Zepbound for weight loss.
In 2023, Zepbound received approval from the US Food and Drug Administration (FDA) as an injectable prescription medicine for treating obesity in adults. The approval in India marks a significant milestone, especially given the increasing prevalence of diabetes and obesity in the country.
How Does Tirzepatide Work?
Tirzepatide works through several mechanisms to manage blood sugar levels and promote weight loss. Here's a detailed look at its functions:
Stimulating Insulin Release
Tirzepatide stimulates the pancreas to release insulin in response to meals. This action helps lower blood sugar levels after eating, which is crucial for managing diabetes.
Reducing Glucagon Release
The medication decreases the release of glucagon, a hormone that raises blood sugar levels. Lower glucagon levels help reduce glucose production by the liver, contributing to better blood sugar control.
Slowing Stomach Emptying
Tirzepatide slows down the emptying of the stomach, which can reduce the rate at which glucose enters the bloodstream after a meal. This helps control postprandial blood sugar spikes, a common challenge in diabetes management.
Reducing Appetite
By acting on the brain's appetite centres, tirzepatide can help reduce hunger and food intake, potentially leading to weight loss. This dual action on blood sugar regulation and appetite suppression makes it a promising candidate for obesity treatment.

Potential Side Effects
While tirzepatide has shown efficacy in managing type 2 diabetes and obesity, it is not without side effects. The common side effects include:
- Nausea
- Diarrhea
- Decreased appetite
- Vomiting
- Constipation
- Indigestion
- Abdominal pain
These side effects are generally mild and manageable. However, there are some serious side effects to be aware of, such as:
- Inflammation of the pancreas (pancreatitis)
- Low blood sugar levels, especially when used with other diabetes medications
- Severe allergic reactions
- Severe stomach problems
- Changes in vision
- Gallbladder problems
Patients experiencing any severe side effects should seek medical attention immediately.
Precautions Before Using Tirzepatide
Before starting tirzepatide, there are several precautions to consider. Here are some key points:
Proper Usage Instruction
Patients should receive proper instruction from their healthcare provider on how to use tirzepatide before the first use. This ensures correct administration and reduces the risk of improper use.
Managing Low Blood Sugar
It is crucial to discuss the risk of low blood sugar and how to manage it with a healthcare provider. Understanding the signs and appropriate responses to hypoglycemia is vital for safety.

Birth Control Considerations
Women taking birth control pills should consult their healthcare provider before using tirzepatide. The medication may affect the effectiveness of oral contraceptives, necessitating alternative or additional birth control methods.
The Future of Tirzepatide in India
The approval of tirzepatide for diabetes management in India is a significant step forward. Its potential approval for weight loss could further revolutionise treatment options for obesity, offering hope to many struggling with weight management. As the review process for obesity indication continues, healthcare providers and patients alike are optimistic about the benefits this drug can bring.
Bottomline
In conclusion, tirzepatide represents a promising advancement in the treatment of both type 2 diabetes and obesity. With its dual action on blood sugar regulation and appetite suppression, it offers a comprehensive approach to managing these chronic conditions. As India prepares to embrace this innovative medication, the future looks brighter for patients seeking effective solutions for diabetes and weight loss.
