Source: Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Working with extreme temperatures, both high and low, is an integral part of many laboratory operations. For many, mentioning a laboratory instantly evokes the mental picture of a Bunsen burner. Bunsen burners and hot plates are used extensively in small and large operations in research laboratories and industries, thus making it necessary for all users to be aware of their safe handling...

Common Ion Effect

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide: This solubility equilibrium may be shifted left by the addition of either silver(I) or iodide ions, resulting in...

2023
Preservation of laboratory samples, specimens, and reagents using extreme cold is routinely performed in biomedical research labs. This video will discuss some of the methods for keeping laboratory samples cold and will explain the correct cooling method to use for each experimental requirement. For example, cooling agents, such as ice and dry ice, are typically used when keeping samples cold during experiments. This video discusses the physical properties of the most commonly used cooling...

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes. When the environmental dynamics fall out of the optimal limit for a given species, changes in metabolism and functioning occur – and this is defined as stress. Plants respond to stress by initiating changes in gene expression - leading to adjustments in plant...
FAQs
The main treatment targets are the effects produced by the host inflammatory response, including congestion, rhinorrhea, sore throat, cough, and fever. Analgesics, antipyretics, decongestants, antihistamines, and cough medicines address selected symptoms, but they do not directly remove the respiratory virus. This distinction explains the supportive nature of medication use.
Different inflammatory effects create different treatment needs. Nasal congestion may prompt consideration of a decongestant, while pain or fever may lead to an analgesic or antipyretic. Rhinorrhea, sore throat, and cough require separate symptom assessment. Pharmacology therefore links the patient’s dominant complaints with targeted treatment rather than applying one universal regimen.
The common cold is caused by respiratory viruses, including rhinoviruses and seasonal coronaviruses, so antibiotics do not target its underlying infectious agent. Medication decisions should instead emphasize supportive, symptom-directed care. Recognizing this difference helps prevent treatment from being based solely on the presence of respiratory symptoms or fever.
These drug categories address different symptom patterns rather than performing the same function. Decongestants are considered for congestion, antihistamines may be selected when relevant symptoms require that approach, and cough medicines target cough. Their use should reflect the patient’s needs, while safety considerations guide whether a particular agent is appropriate.
Begin by identifying the symptoms causing the greatest burden, then select an appropriate symptom-directed category and review safety considerations before use. A patient with prominent congestion may need a different approach from one whose main concerns are pain, fever, or cough. This process keeps treatment focused and avoids unnecessary medication.
Combination products should be examined according to the symptoms they are intended to address and the safety of their overall ingredient mix. Because common cold complaints vary among patients, a multi-ingredient product may not be necessary for every presentation. Reviewing the product’s pharmacologic components supports more deliberate, symptom-based medication selection.
