Formulation and Pharmaceutical Assessment of Annona muricata Oral Capsules and Suspension as Antidiarrhea Dosage Forms

Abstract

Annona muricata (Annonaceae) is a tropical plant widely known for its edible fruits. Recent scientific studies have confirmed the folkloric use of its seeds as an antidiarrheal agent. /is study sought to formulate capsules and suspensions using the ethanolic extract from Annona muricata seeds. /e dried ethanolic extract was formulated into granules and subsequently encapsulated. /e suspension formulated was assessed for sedimentation rate, sedimentation volume, viscosity, dissolution, drug content, and flow rate, while pharmacopeia tests such as disintegration, dissolution, uniformity of weight, and drug content were carried out on the formulated capsules. /e formulated suspension passed the drug content and in vitro release studies. Annona muricata suspension exhibited pseudoplastic flow with good sedimentation rate and sedimentation volume. /e formulated capsules passed the in vitro dissolution studies, weight uniformity, disintegration, and drug content tests. /e ethanolic extract of Annona muricata seeds was appropriately formulated into standardized solid and liquid oral dosage forms.
