Megasid Film Tablet contains a vital active ingredient, clarithromycin, with each tablet delivering 500 mg of this antibiotic. However, the tablet is more than just its active component. It includes several excipients, each serving a specific purpose in pharmaceutical formulation.

Excipients in Megasid Film Tablet

  1. Sodium Starch Glycolate (Explotab): This starch variant acts as a disintegrant, facilitating tablet breakdown and prompt release of the active ingredient upon contact with water.
  2. Hydroxypropyl Cellulose: Derived from cellulose, it serves as a binder and filler within the tablet.
  3. Microcrystalline Cellulose (Avicel pH 101 and Avicel pH 112): These refined wood pulp derivatives function as texturizers and anti-caking agents.
  4. Sodium Stearyl Fumarate: This compound acts as a lubricant within the tablet.
  5. Talc: Employed as a glidant, talc enhances the flow properties of the powder mixture during tablet manufacturing.
  6. Stearic Acid: Another lubricant in tablet formulation.
  7. Colloidal Silicon Dioxide (HDK-N20): Functioning as both a glidant and anti-caking agent, it contributes to tablet stability.
  8. Ethyl Alcohol: This solvent is used in the film coating process.
  9. Opadry White Y-1-7000 (HPMC 2910/Hypromellose 5 cP, Titanium Dioxide, Macrogol /PEG 400): This film coating enhances tablet appearance and ease of swallowing.
  10. Sorbic Acid: Acting as a preservative, it helps maintain tablet integrity.
  11. Banana Flavor: Added for improved taste.
  12. Deionized Water: Serves as a solvent in the tablet’s manufacturing process.

The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
