Based on the information he is vomiting
dark brown beads like coffee grains that is definitive observation and mostly due to "INTERNAL BLEEDING" and immediate medical attention is needed.
The brown color grains is basically a blood drops which when reacts with the stomach acid will turn in dark brown colored grains. If the patient is vomiting such grains needs to be evaluated by the endoscope and general surgeon
or Gastrointestinal Surgeon will do the procedure ( endoscopy
- a flexible tube with camera is attached and help to visualize the inner body part which are not visually seen). The bleeding in access will make him feel dizzy and will decrease the strength. Hence the medical care is needed as soon as possible.
Now about the drugs ,
is to reduce the acid formation,
2) Enablex is for help in urination - May further increase the complication of internal bleeding as it will increase the gastric emptying time (time taken to empty stomach)
3) Ropinerole, tamulosin are used for parkinson
- is basically relaxant.
None except enablex may cause some problem.
TAKE MEDICAL CARE AS SOON AS POSSIBLE.
TREATMENT: need an endoscopic repair/ plugging of bleeding vessel .
Hope it helps.
