给药方式的选择在药物研究和治疗中至关重要。不同的给药途径包括口服、静脉注射、皮下注射、经皮吸收、呼吸道给药等。口服是常见的、便捷的途径，适用于口服制剂。静脉注射可实现药物迅速达到全身循环，适用于紧急情况。皮下注射适用于慢释制剂。经皮吸收适用于局部治疗，呼吸道给药可直接影响呼吸系统。选择给药方式需考虑药物性质、治疗目标、药效学和患者接受程度，以提高治疗效果。

The choice of delivery method is crucial in drug research and treatment. Different administration routes include oral administration, intravenous injection, subcutaneous injection, transdermal absorption, respiratory tract administration, etc. Oral administration is a common and convenient route and is suitable for oral preparations. Intravenous injection allows the drug to quickly reach the systemic circulation and is suitable for emergency situations. Subcutaneous injection is suitable for slow-release formulations. Transdermal absorption is suitable for local treatment, and respiratory administration can directly affect the respiratory system. The choice of administration method needs to consider the properties of the drug, therapeutic goals, pharmacodynamics and patient acceptance to improve the therapeutic effect.
