Upper Respiratory Drugs: First and Second-Generation Antihistamines01:15

Upper Respiratory Drugs: First and Second-Generation Antihistamines

Antihistamines are a class of drugs widely used to alleviate the symptoms of allergies, such as sneezing, itching, and nasal congestion. They work by inhibiting the actions of histamine, which is released by immune cells in response to allergenic substances or tissue injuries.
Histamine binds to specific receptor sites, known as H1 receptors, on tissue cells, triggering inflammation and swelling. Antihistamines combat these effects by competing with histamine for these receptor sites. By...
Cholinergic Antagonists: Pharmacokinetics01:24

Cholinergic Antagonists: Pharmacokinetics

Cholinergic antagonists—such as antimuscarinics—are available in oral, topical, ocular, parenteral, and inhalational formulations. Most antimuscarinics are oral formulations,  while scopolamine is available as a topical patch, and ipratropium and tiotropium are available as inhalation aerosols or powders. Atropine, tropicamide, and cyclopentolate are topically instilled in the eye. Most antimuscarinics are lipid-soluble and readily absorbed from the gastrointestinal tract and the conjunctiva.
Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists01:28

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...

Cholinergic Antagonists: Therapeutic Uses

Antimuscarinic drugs have various therapeutic applications by inhibiting parasympathetic stimulation in different systems. Here are the key therapeutic uses of antimuscarinics:    
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal secretions in common...
Cholinergic Antagonists: Pharmacological Actions01:28

Cholinergic Antagonists: Pharmacological Actions

Antimuscarinic drugs block muscarinic receptors in multiple systems, including the gut, eye, smooth muscles, respiratory tract, cardiovascular, and central nervous systems. They produce similar effects with varying selectivity depending on the specific agent and tissue. Here are the key pharmacological actions of antimuscarinics:
Gastrointestinal Effects: Antimuscarinics reduce gut contractions, increase gastric emptying, and slow intestinal transit. They partly inhibit gastric acid secretion...
Anxiolytic Drugs: Benzodiazepines and Buspirone01:29

Anxiolytic Drugs: Benzodiazepines and Buspirone

Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

Area of Science:

  • Pharmacology
  • Neuroscience
  • Traffic Safety

Background:

  • Driving performance relies on cognitive, psychomotor, and perception functions.
  • Central nervous system (CNS) adverse effects of H1 antihistamines can impair driving.
  • Classification of H1 antihistamines requires rigorous assessment of their impact on driving.

Purpose of the Study:

  • To evaluate the impact of H1 antihistamines on driving performance.
  • To establish criteria for classifying H1 antihistamines as non-sedating.
  • To review methodologies for assessing H1 antihistamine effects on driving.

Main Methods:

  • Utilized standardized objective tests: Choice Reaction Time, Critical Flicker Fusion, Digital Symbol Substitution Test.
  • Employed functional brain imaging: Positron Emission Tomography, functional Magnetic Resonance Imaging.
  • Included neurophysiological studies: Multiple Sleep Latency Test, evoked potentials.
  • Incorporated simulated and real driving studies: driving simulators, Highway Driving Test, Car Following Test.

Main Results:

  • Data from diverse objective tests and driving studies are essential.
  • Specific metrics like Standard Deviation Lateral Position and Brake Reaction Time are key indicators.
  • Comprehensive evaluation is needed to determine non-sedating properties.

Conclusions:

  • A H1 antihistamine can only be classified as truly non-sedating after thorough evaluation.
  • Objective cognitive, psychomotor, and driving tests are indispensable for this classification.
