Abstract:
Aim: Inhalable microspheres made of polymers as a targeted drug delivery system have been developed to overcome the limitation of current treatments in Tuberculosis. Materials & methods: Isoniazid inhalable microspheres were created using a gelation ionotropic method with sodium alginate, carrageenan and calcium chloride in four different formulations. Result: The particle morphology has smooth surfaces and round spherical shapes with sizes below 5 μm; good flowability. The drug loading and entrapment efficiency values ranged from 1.69 to 2.75% and 62.44 to 85.30%, respectively. The microspheres drug release followed the Korsmeyer-Peppas model, indicating Fickian diffusion. Conclusion: Isoniazid inhalable microspheres achieved as targeted lung delivery for tuberculosis treatment.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Drug Delivery: Enteral Route
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

Factors Influencing Drug Absorption: Pharmaceutical Parameters
Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...
