Does pilocarpine lower BP?
Pilocarpine strongly increases arterial pressure which activates baroreceptors, thereby enhancing the activity of NTS and CVLM neurons, before the release of inhibitory signals in the RVLM trying to reduce sympathetic activation.
What are the indications of pilocarpine?
DOSAGE & INDICATIONS
- For the treatment of increased intraocular pressure (IOP) in patients with glaucoma or ocular hypertension or for the prevention of increased IOP associated with laser surgery.
- For miosis induction.

- For the treatment of xerostomia and/or xerophthalmia†.
How does Miosis help glaucoma?
Miotics. Miotics are eye drops that cause the pupil to constrict, allowing the blocked drainage angle to open. They may be used two, three, or four times daily. These medications are now reserved for use in people whose glaucoma does not improve with other medications.
