De camino a casa paso por una farmacia que esté abierta y te la compro.
Assuming the person goes by this Pharmacy every day and it is always open at that time I'm perplexed as to why the subjective form or the verb estar is being used.

Assuming the person goes by this Pharmacy every day and it is always open at that time I'm perplexed as to why the subjective form or the verb estar is being used.
In your example you are talking about a quality or condition of the pharmacy (being open). You could consider that a "hypothetical" condition ("on my way home if I come across an open pharmacy, I'll buy it").
Check this website to learn more about the uses of the subjunctive (when you should use the subjunctive instead of another verb mood)
I quote directly from the site usage and examples:
Para hablar de las características de personas o cosas desconocidas, no concretas, hipotéticas:
- Quiero comprar un departamento que tenga tres dormitorios.
- Necesito una secretaria que sepa inglés, alemán, francés y español.
- Busco amigos que sean sinceros, simpáticos y que hablen español.
