Understanding Solifenac 10: What Is It?
Solifenac 10 mg tablet is a pharmaceutical preparation containing solifenacin as its active ingredient. Solifenacin belongs to a class of medications known as anticholinergics, which are used to treat various urological conditions by affecting the way muscles in the bladder function.
The medication comes in tablet form with a strength of 10 milligrams, making it suitable for specific dosing requirements in adult patients. Solifenac 10 has been developed through extensive research and clinical trials to ensure safety and efficacy.
Detailed Composition of Solifenac 10 mg Tablet
Active Ingredient
Solifenacin 10 mg: This is the primary active pharmaceutical ingredient in Solifenac 10 tablet. Solifenacin is a selective M3-receptor antagonist that works by blocking acetylcholine at the muscarinic M3-receptor sites in the bladder smooth muscle.
Inactive Ingredients (Excipients)
The formulation of Solifenac 10 mg tablet includes several inactive ingredients that serve important pharmaceutical purposes:
- Microcrystalline Cellulose: Acts as a binder and diluent, providing tablet structure and integrity
- Lactose Monohydrate: Used as a filler and sweetening agent
- Magnesium Stearate: Functions as a lubricant to prevent tablet sticking during manufacturing
- Croscarmellose Sodium: A disintegrant that helps the tablet break down in the digestive system
- Hypromellose: A film-forming agent that aids in tablet coating and protection
- Titanium Dioxide: Provides white coloring to the tablet
- Iron Oxide Red: Used for tablet color identification
- Polyethylene Glycol: A plasticizer that enhances tablet flexibility
These excipients are carefully selected to ensure the tablet's stability, bioavailability, and patient compliance.
Mechanism of Action
Solifenac 10 mg works through a specific pharmacological mechanism that distinguishes it from other anticholinergic medications:
How Solifenacin Functions
Solifenacin selectively antagonizes M3-muscarinic receptors in the bladder detrusor muscle. This antagonism prevents acetylcholine from binding to these receptors, which results in decreased muscular contractions of the bladder. This mechanism helps reduce overactive bladder symptoms and improves bladder control.
The selectivity of solifenacin for M3-receptors is clinically significant because it minimizes side effects typically associated with non-selective anticholinergic medications.
Therapeutic Uses and Indications
