Labetalol hydrochloride, the active ingredient in Labetalol tablets, is a racemic mixture of two enantiomers: R-(+)-labetalol and S-(−)-labetalol. Each tablet typically contains a combination of these enantiomers in varying ratios depending on the formulation and dosage strength.
In addition to the active ingredient, Labetalol tablets may also contain inactive ingredients such as microcrystalline cellulose, starch, colloidal silicon dioxide, magnesium stearate, and other pharmaceutical excipients used to formulate the tablet.
These inactive ingredients help to stabilize the tablet, aid in the absorption of the active ingredient, and ensure the tablet's integrity during storage and administration. The specific composition of inactive ingredients can vary depending on the manufacturer and formulation of the tablet.
It's important for individuals who are prescribed Labetalol to inform their healthcare provider of any known allergies or sensitivities to medications or specific ingredients to avoid any potential adverse reactions.
