Aim of the study: The aim is to analyse and present influential factors of marketing and management in OTC drug pharmacological campaigns. Study design: A cross-sectional study. Participants and methods: Respondents are of different generations which include generations Z, Y, X and Baby boomers. Data collection was conducted via an online questionnaire in FormsApp. Results: The questionnaire was administered to 108 respondents. There is a statistically significant difference between the generations of the respondents. In general, the respondents recognize different OTC drugs marketing campaigns, but do not think that they influence their buying decision. On the other hand, the most correct answers are visible when recognizing the colours and packaging of OTC products. Moreover, most of the respondents wanted to buy some of the given OTC products because of their appealing packaging design. When it comes to gender, most of the correct answers, when recognizing OTC products, were given by female respondents. Also, when it comes to age, most of the correct answers were given by generation Y (25-39 years old). Conclusion: When recognizing OTC products marketing campaigns, the female respondents and respondents in generation Y stood out with more correct answers. Even though most of the respondents denied that the colour and design of products influence their choice of OTC drugs, the correlation between remembering various products with colour and packaging design is visible. When it comes to choosing OTC drugs, most of the respondents buy the products they have been using for longer periods of time, more precisely the products' effectiveness, followed by recommendation given by family or friends. On the other hand, the least given answer was choosing OTC products based on their price.
