Ligtas na Pagsasama ng mga Gamot

Loperamide at Buscopan (Hyoscine Butylbromide)

Oo, ligtas na sabay na inumin ang loperamide at buscopan dahil magkaiba ang kanilang mekanismo ng aksyon at walang kilalang drug interaction sa pagitan nila. 1

Paano Gumagana ang Bawat Gamot

  • Ang loperamide ay tumutulong sa pagpapabagal ng paggalaw ng bituka at pagpapababa ng dami ng tubig sa dumi, ginagamot ang pagtatae 2, 3
  • Ang buscopan (hyoscine butylbromide) ay antispasmodic na nakakarelaks ng smooth muscle sa tiyan, ginagamot ang pulikat at sakit sa tiyan 1
  • Dahil magkaiba ang target receptors nila (loperamide sa opioid receptors, buscopan sa muscarinic receptors), walang overlap sa kanilang aksyon 4, 1

Tamang Pag-inom

  • Loperamide: 4 mg unang dose, pagkatapos 2 mg pagkatapos ng bawat loose stool, maximum 16 mg sa loob ng 24 oras 3, 5
  • Buscopan: Karaniwang 10-20 mg, 3-4 beses sa isang araw 1
  • Maaaring sabay na inumin o hiwalay, walang kailangang time interval 1

Mga Babala

  • Huwag gumamit ng loperamide kung may lagnat na >38.5°C, dugo sa dumi, o matinding sakit sa tiyan 3, 5
  • Siguraduhing may sapat na hydration bago uminom ng loperamide 3
  • Ang buscopan ay may mababang systemic absorption kaya minimal ang side effects, pero maaaring magdulot ng dry mouth 1

Neozep at Loratadine

Hindi inirerekomenda ang pagsasama ng neozep at loratadine dahil pareho silang may antihistamine component, na maaaring magdulot ng excessive sedation at overdose ng antihistamine. 6

Bakit Hindi Dapat Pagsabayin

  • Ang neozep ay naglalaman ng chlorpheniramine (first-generation antihistamine), phenylephrine, at paracetamol
  • Ang loratadine ay second-generation antihistamine
  • Ang pagsasama ng dalawang antihistamine ay maaaring magdulot ng:
    • Labis na antok at drowsiness
    • Dry mouth, blurred vision
    • Urinary retention
    • Confusion, lalo na sa matatanda 6

Tamang Approach

  • Pumili ng isa lamang: Kung kailangan ng antihistamine para sa allergy, gumamit ng loratadine dahil mas kaunti ang side effects at hindi nakaka-antok 6
  • Kung kailangan ng decongestant (phenylephrine) para sa sipon, maaaring gumamit ng loratadine + phenylephrine alone (hindi neozep)
  • Kung kailangan ng pain reliever, maaaring idagdag ang paracetamol separately sa loratadine 6

Algorithm para sa Pagpili

  1. Kung ang pangunahing sintomas ay allergy (pantal, kati, bahing): Gumamit ng loratadine 10 mg once daily 6
  2. Kung ang pangunahing sintomas ay sipon at lagnat: Gumamit ng neozep, pero huwag idagdag ang loratadine 6
  3. Kung may allergy at sipon: Gumamit ng loratadine + phenylephrine separately, iwasan ang neozep 6

Mahalagang Tandaan

  • Huwag kailanman mag-double dose ng antihistamine dahil walang additional benefit pero tumataas ang risk ng side effects 6
  • Kung hindi sigurado, pumili ng loratadine dahil mas safe at hindi nakaka-antok 6
