Additional Routes of Drug Administration
Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
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 Elimination by Renal Route: Tubular Secretion
Once the process of glomerular filtration is completed, blood carrying unfiltered drug molecules traverses through efferent arterioles and makes its way into the peritubular capillaries in the proximal tubule. A variety of carriers play a pivotal role in actively secreting drugs from these peritubular capillaries into the tubular fluid. The organic anion transporter transfers acidic drugs, against an electrochemical gradient, from the peritubular capillaries into the renal tubule cells and...
Direct-Acting Cholinergic Agonists: Pharmacokinetics
Direct-acting cholinergic agonists, such as synthetic choline esters and naturally occurring alkaloids, exert their effects by enhancing the actions of acetylcholine and stimulating the parasympathetic nervous system. Synthetic choline esters share structural similarities with acetylcholine. For example, they have a positively charged quaternary ammonium or onium group, contributing to their hydrophilic characteristics. As a result, they are poorly absorbed in the body through oral...
Routes of Drug Administration: Overview
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Drug Delivery: Miscellaneous Routes
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
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 through the...

Drug Excretion: Miscellaneous Routes
Drug excretion involves various organs, including the liver, intestines, skin, and eyes. In the case of drugs or toxins, they can be actively secreted into bile by transporters in the hepatocyte's canalicular membrane. These substances enter the GI tract during digestion and may be reabsorbed into the body from the intestine. This process, known as enterohepatic recycling, can significantly prolong the presence and effects of a substance in the body. To interrupt this cycle, specific substances...
