Mechanisms of sublingual immunotherapy
1Allergy and Clinical Immunology, Imperial College, London, UK.
Summary
Sublingual immunotherapy effectively treats allergic rhinitis and asthma, particularly house dust mite allergies. Further research into its mechanisms, similar to subcutaneous immunotherapy, will enhance treatment strategies.
Area of Science:
- Immunology
- Allergology
- Pharmacology
Background:
- Sublingual immunotherapy (SLIT) is an effective treatment for allergic rhinitis.
- Emerging strategies focus on SLIT for allergic asthma, especially house dust mite allergies.
- Understanding SLIT's mechanisms is crucial for optimizing treatments.
Purpose of the Study:
- To review the potential mechanisms of action for sublingual immunotherapy.
- To compare SLIT mechanisms with those of subcutaneous immunotherapy (SCIT).
- To highlight the need for improved understanding to develop advanced therapeutic programs.
Main Methods:
- Review of existing clinical and animal studies on SLIT.
- Comparative analysis of immunological changes induced by SLIT and SCIT.
- Synthesis of current knowledge on immunotherapy mechanisms.
Main Results:
- SLIT demonstrates efficacy and tolerability in allergic rhinitis treatment.
- Immunological changes in SLIT show similarities to those observed in SCIT.
- Further research is needed to fully elucidate SLIT's precise mechanisms.
Conclusions:
- SLIT is a viable treatment for allergic rhinitis and asthma.
- Enhanced understanding of SLIT mechanisms will improve therapeutic development.
- Comparing SLIT and SCIT offers insights into immunotherapy's immunological effects.

Overview
Vaccines
Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
Routes of Drug Administration: Enteral
Medications can be administered through the enteral route using liquids, capsules, or tablets.
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,...

Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
Drug Delivery: Enteral Route
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.
