Formulation and Evaluation of Chrono-Modulated Drug Delivery System for Asthma

Abstract

This study's main goal was to develop and assess a single-unit time-controlled oral pulsatile medication delivery system that contains antiasthmatic drugs to prevent nocturnal asthma attacks. Time-dependent delivery systems are made to release medication quickly or gradually after a certain amount of time, known as the lag time. Medication and chronotherapeutic formulations can be administered into the colon using these devices, among other uses.

The creation of a time-dependent press-coated tablet was the aim of this project. In order to treat nocturnal asthma, this work aims to develop and evaluate a chronomodulated drug delivery system of antiasthmatic medication, a selective β2 receptor blocker, which is a legitimate and acceptable rationale. This paper aims to give an overview of the main formulation techniques and the reasoning behind delayed-release dosage forms. When a medication is prescribed for the pharmacological treatment of asthma, maintain a lag time of 4-5 hours before drug release and a lag time of 4-5 hours between plasma peak concentration and controlled release. A five-hour lag time was the target. The gadget is utilized before going to bed. and is anticipated to administer the medication five hours later, or about four in the morning, when asthma attacks are most frequent.The direct compression method was used to create drug-containing core tablets with different superdisintegrant compositions, such as sodium starch glycolate, croscarmellose sodium, and crospovidone. Press-coated tablets were produced using hydroxypropyl methylcellulose K4M in a variety of hydrophobic and hydrophilic polymer compositions after the fast-dissolving core tablet formulation was selected.The drug release profile and in vitro lag time in simulated stomach and intestinal fluids were used to select and quantify the coated polymers.The best instant-release core pill was determined to be the crospovidone formulation, which had the quickest dissolving time of 30 minutes. After a five-hour lag, the press-coated tablet formulation with a 350 mg barrier layer covering the core tablet demonstrated rapid and complete drug release. After six months, accelerated stability evaluations of the updated formulation revealed no appreciable changes in the release profile. The in vitro dissolving study showed that the amount and kind of coating polymer utilized had a significant impact on the lag time before drug release. Press-coating techniques can be used to produce time-controlled pulsatile release tablets.
