Primary Outcome  
Outcome  TimePoints 
The time required for the tablet to disintegrate in the gastrointestinal tract and the location where disintegration occurs will be evaluated using Gamma Scintigraphy. The gastric residence time, which is the duration the tablet remains in the stomach, and the intestinal arrival time, when the tablet reaches the small intestine, will also be assessed. The location of the tablet at different time points will be recorded. Additional imaging at 20 and 24 hours post-dose may be performed if necessary. The time taken for the tablet to transit into the colon will be observed, and imaging may be discontinued once colon transit is achieved  00.00 (within 5 minutes post-dose), 01.00, 02.00, 04.00, 06.00, and 08.00 hours post-dose

Clinical examination findings, including assessments of general well-being, will be conducted  o min, 4 hours, 8 hours post-dose, and at study completion 
Vital signs, including sitting blood pressure, pulse rate, and body temperature, will be monitored  t check-in, pre-dose, 4 hours, and 8 hours post-dose, and as needed during the study 
Laboratory tests such as hematology, biochemistry, serology, and urine analysis will be performed at check-in and prior to end of study to detect any clinically significant abnormalities.  O mins and end of the study

Brief Summary  

The study titled “A Pharmacoscintigraphy Study to Observe the Disintegration Pattern and Gastric Emptying Pattern of Vitamin B12 1500 mcg SR Oral Tablet (Containing Folic Acid, Vitamin B6, and Vitamin D3 1000 IU) Marketed by Corona Remedies Limited in 6 Healthy Adult Human Subjects” is an open-label, single-arm, single-dose clinical investigation conducted to assess the disintegration and gastric emptying characteristics of a radiolabelled Vitamin B12 sustained-release tablet in healthy volunteers.

The primary objective of the study is to evaluate the disintegration pattern and gastric emptying pattern of the investigational product using 99mTc-based Gamma Scintigraphy. The secondary objective is to monitor the safety and tolerability of the study drug in healthy adults.

A total of six healthy male subjects aged between 18 to 45 years, with a Body Mass Index (BMI) of 18.5–30 kg/m² and weighing at least 50 kg, will be enrolled. Each subject will undergo thorough screening, including medical history, physical examination, and laboratory tests prior to enrollment. Subjects will be housed for at least 2 hours before dosing and for at least 12 hours post-dose, with follow-up imaging at 20 and 24 hours if required. The study duration is expected to be 8 days including screening, dosing, and follow-up.

The investigational product, a Vitamin B12 1500 mcg SR tablet (containing Folic Acid, Vitamin B6, and Vitamin D3), will be radiolabelled with Technetium-99m and administered as a single oral dose under supervision. Sequential Gamma Imaging will be conducted at multiple time points post-dose to track the tablet’s disintegration, gastric residence time, and intestinal arrival.

Safety assessments will include monitoring of vital signs, clinical examination, adverse event reporting, and laboratory tests at various time points. Additional blood samples will be collected at 2, 8, 24, 36, and 48 hours post-dose for Vitamin B12 estimation.

Strict inclusion and exclusion criteria have been defined to ensure subject safety and data integrity. Statistical analysis will be performed using appropriate software, and compensation will be provided as approved by the Institutional Ethics Committee.

The study will be conducted as per established regulatory guidelines, and the final report will be prepared upon study completion.
