Final answer:
H2-receptor antagonists can be administered intramuscularly or intravenously in health-care settings, with intravenous administration providing quicker results. Oral administration is the most common method for home use due to its convenience for self-administration.
Step-by-step explanation:
Proper Administration of H2-Receptor Antagonists
H2-receptor antagonists can be administered via different routes depending on the clinical situation and patient needs. Intramuscular injections are one method, involving an injection of medication directly into the muscle, allowing for slower absorption than intravenous administration but faster than oral intake. However, this method is generally performed in health-care settings. Subcutaneous injections are similar to intramuscular injections but are injected into the fatty tissue under the skin. These are not typically used for H2-receptor antagonists.
Intravenous infusions are a common method used in hospital settings, especially when rapid action is required or when the patient cannot take medications orally. Intravenous administration ensures that a precise dose is delivered directly into the bloodstream, providing quick and effective results. Lastly, oral administration is the most common and convenient method for home administration, as it allows for self-administration by the patient, although this route may have slower onset of action compared to parenteral routes.
