Tearsol

Tearsol Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Tearsol is a brand name. Its generic name is Hypromellose.

Introduction

Tearsol also known as hydroxypropyl methylcellulose (HPMC) is a polysaccharide often used as an aqueous dispersion of methylcellulose polymers. It is a semi-synthetic, non-ionic cellulose ether used as an excipient or pharmaceutical base in pharmaceuticals, foods, cosmetics, and industrial products. Tearsol is white to cream colored, odorless, and tasteless powder that is highly viscous, soluble in water, and forms stable gel.

Uses

Tearsol is used in the production of emulsions, tablets and capsules and other pharmaceutical forms due to its superior qualities such as water solubility, ease in dispersing, good resistance to salting out effects, and low irritation to the gastro-intestinal tract. It is also used to thicken and stabilize lotions, creams and other cosmetic and personal care products. Additionally, Tearsol is also used as an eye drop since it helps keep the tear film moisten and comfortable.

Mechanism of action

Tearsol is a non-ionic cellulose ether which forms a gel when it comes into contact with water. When it is used in Pharmaceuticals, it helps stabilize and thicken the mixture. This helps to keep the device from separating and ensures its effective performance. In cosmetics, it helps retain moisture in the skin, which prevents irritation and keeps the skin hydrated. As an eye drop, it helps keep the tear film moist.

How long does it take to work?

Some Frequently Asked Questions About Tearsol

What is Tearsol?

Tearsol, also known as hydroxypropyl methylcellulose or HPMC, is a gelling and thickening agent derived from cellulose. It is used in a variety of industries, including medical, pharmaceutical, and food.

What is Tearsol used for?

Tearsol is used to thicken, stabilize, and bind drugs and food products. It is often used as an excipient in tablets and capsules and is frequently used in pharmaceutical ophthalmic solutions, suspensions, and ointments.

How does Tearsol work?

Tearsol works by absorbing and dissolving in water as it forms a gel-like consistency similar to that of agar. This thick gel matrix then prevents the active ingredients in the drug from settling or separating out. Additionally, the gel helps to stabilize and bind the drug molecules, thus improving drug efficacy and shelf life.

What is Tearsol made of?

Tearsol is derived from cellulose, which is a polymer of glucose units linked together. It is produced by a chemical process that involves hydroxypropylation, which replaces some of the hydrogens on the cellulose molecule with hydroxypropyl groups.

What is the difference between Tearsol and cellulose?

The main difference between Tearsol and cellulose is that Tearsol is a modified form of cellulose, with some of the hydrogens on the cellulose molecule replaced with hydroxypropyl groups. This modified cellulose has the ability to absorb, dissolve, and form a gel, making it an excellent thickening and gelling agent.
